    1991-11-01

    This paper describes the problems that seismic crews face in Papua New Guinea. The complex geologic conditions which often entail karstified carbonate rocks which are overlying folded sedimentary and igneous rocks, cause severe problems with data collection and interpretation. Secondly, the rugged topography and dense rain forest vegetation along with the wild animals and diseases create inaccessible or undesirable work areas. However, these conditions can be overcome and this paper briefly describes how one exploration company uses local natives to assist in development of reliable seismic surveys.

    1993-02-15

    Light, sweet Kutubu crude from near Lake Kutubu in Papua New Guinea has been assayed. Production of the 44[degree]-gravity, 0.04-wt% sulfur crude-Papua New Guinea's first commercial oil-began in June 1992. Most of the early production will likely be sold to refineries in Sydney and Brisbane. Production of Kutubu is expected to reach 100,000 b/d, and possibly 140,000 b/d. The paper lists the properties of the whole crude and the following boiling point ranges (C): 21--70; 70--140; 140--190; 140--230; 190--230; 230--360; 360--540; 360+; and 540+.

    Operators, paced by a feisty independent based in Port Moresby, have drilled a string of discoveries near the infrastructure of the Kutubu development project that supports Papua New Guinea crude exports. All signs point to the increasing likelihood of good sized -- maybe world class -- oil discoveries that promise to sustain exploration and development interest beyond 2000. Also in the offing are world class gas strikes that eventually could support a liquefied natural gas export project. And integration is the newest concept in Papua New Guinea petroleum. Efforts are under way to build the country's first refineries. Most operators in Papua New Guinea believe thy have merely scratched the surface of the country's oil and gas potential. Thy agree there still will be frustrations and setbacks -- political as well as technical -- but the prevailing opinion is that these problems are no greater than they are in a number of other countries with similar exploration/development potential. The paper discusses the development of Papua New Guinea's oil and gas industry, and exploratory drilling in areas other than Kutubu.

    1980-11-01

    This report presents the results of an engineering and economic assessment of new and retrofit industrial combustion equipment for wood-fuel use in Papua New Guinea. Existing industrial combustion equipment and practices in Papua New Guinea are appraised. Potential industrial wood-fuel systems that utilize wood, wood wastes, charcoal and pyrolytic oils and which are particularly applicable to Papua New Guinea are identified. An economic assessment of wood-fuel systems is conducted for eleven case studies which are representative of a cross-section of Papua New Guinea industry. Conclusions and recommendations are presented to aid both government and industry in Papua New Guinea in fostering the development of appropriate wood-fuel technologies and thereby help displace the consumption of imported petroleum.

    1991-03-01

    This paper reports on several types of remote sensing surveys that have been acquired of the Eastern Papuan Fold Belt, in the Gulf Province of Papua New Guinea. These include aerial photographs, Landsat Multispectral Scanner (MSS) and Synthetic Aperture Radar (SAR). Each has been used by Petro-Canada Inc. for interpreting the geologic structure and stratigraphy of onshore hydrocarbon prospects. Analysis of available remotely sensed imagery reveals greater structural complexity than shown on published geologic maps. Foremost among the images is SAR because of its low, artificial sun angle.

    1996-07-01

    One of the most active hydrocarbon exploration provinces of the last decade has been the fold and thrust belt of Papua New Guinea. Geologic remote sensing is an indispensable part of the exploration process in that remote and rugged area where usable seismic data are obtainable only locally, if at all. Photointerpretation of stereo synthetic aperture radar imagery has been especially useful in conventional lithostratigraphic mapping, both local and regional. Results of remote sensing imagery interpretation, integrated with surface geologic data, limited seismic, and balanced structural cross sections, facilitated the documentation of structural styles and provided the basis for a new, regional structural model. The role of remote sensing during various stages of the exploration process is summarized; imagery and map examples are presented.

    Papua New Guinea (PNG) lies at the eastern end of the Indonesian Archipelago. Its coincidence with the collision zone between the Australian continental plate and the Pacific plate has influenced the geologic evolution of the country. These two major features have rubbed, abraded, overridden, penetrated, and slid by each other to form the geologic complex of basins, uplifts, foundered blocks, and volcanic zones known today as PNG. Since the turn of the century, exploration for oil and gas has produced a melange of data, ideas, and theories, which perhaps are more complex than the physical geology of the region itself. In 1982, the PNG Department of Minerals and Energy initiated a comprehensive study of the hydrocarbon potential of the country through its Geological Survey. The study was financed through International Monetary Fund (World Bank) and OPEC funds. As a result of this work, exploration potential was demonstrated, new play concepts were proposed, and new exploration efforts were introduced following a call for international tenders. These results will be outlined and illustrated.

    High resolution mitochondrial DNA (mtDNA) restriction maps, consisting of an average of 370 sites per mtDNA map, were constructed for 119 people from 25 localities in Papua, New Guinea (PNG). Comparison of these PNG restriction maps to published maps from Australian, Caucasian, Asian and African mtDNAs reveals that PNG has the lowest amount of mtDNA variation, and that PNG mtDNA lineages originated from Southeast Asia. The statistical significance of geographic structuring of populations with respect to mtDNA was assessed by comparing observed G{sub ST} values to a distribution of G{sub ST} values generated by random resampling of the data. These analyses show that there is significant structuring of mtDNA variation among worldwide populations, between highland and coastal PNG populations, and even between two highland PNG populations located approximately 200 km apart. However, coastal PNG populations are essentially panmictic, despite being spread over several hundred kilometers. The high resolution technique for examining mtDNA variation, coupled with extensive geographic sampling within a single defined area, leads to an enhanced understanding of the influence of geography on mtDNA variation in human populations.

  10. Sources and management of hazardous waste in Papua New Guinea

    1996-12-31

    Papua New Guinea (PNG) has considerable mineral wealth, especially in gold and copper. Large-scale mining takes place, and these activities are the source of most of PNG`s hazardous waste. Most people live in small farming communities throughout the region. Those living adjacent to mining areas have experienced some negative impacts from river ecosystem damage and erosion of their lands. Industry is centered mainly in urban areas and Generates waste composed of various products. Agricultural products, pesticide residues, and chemicals used for preserving timber and other forestry products also produce hazardous waste. Most municipal waste comes from domestic and commercial premises; it consists mainly of combustibles, noncombustibles, and other wastes. Hospitals generate pathogenic organisms, radioactive materials, and chemical and pharmaceutical laboratory waste. Little is known about the actual treatment of waste before disposal in PNG. Traditional low-cost waste disposal methods are usually practiced, such as use of landfills; storage in surface impoundments; and disposal in public sewers, rivers, and the sea. Indiscriminate burning of domestic waste in backyards is also commonly practiced in urban and rural areas. 10 refs., 4 tabs.

    Enzymes can be used to catalyze a myriad of chemical reactions and are a cornerstone in the biotechnology industry. Enzymes have a wide range of uses, ranging from medicine with the production of pharmaceuticals to energy were they are applied to biofuel production. However, it is difficult to produce large quantities of enzymes, especially if they are non-native to the production host. Fortunately, filamentous fungi, such as Aspergillus niger, are broadly used in industry and show great potential for use a heterologous enzyme production hosts. Here, we present work outlining an effort to engineer A. niger to produce thermophilic bacterial cellulases relevant to lignocellulosic biofuel production.

  12. Papua New Guinea MT: Looking where seismic is blind

    Hoversten, G.M.

    1996-11-01

    Hydrocarbon exploration in the Papuan fold belt is made extremely difficult by mountainous terrain, equatorial jungle and thick karstified Miocene limestones at the surface. The high-velocity karstified limestones at or near the surface often render the seismic technique useless for imaging the subsurface. In such areas magnetotellurics (MT) provides a valuable capability for mapping subsurface structure. Numerical and field data examples are presented which demonstrate the severity of the 1D errors and the improvements in accuracy which can be achieved using a 2D inverse solution. Two MT lines over adjacent anticlines, both with well control and seismic data, are used to demonstrate the application of 1D and 2D inversions for structural models. The example over the Hides anticline illustrates a situation where 1D inversion of either TE or TM mode provides essentially the same depth to base of Darai as 2D inversion of both TE and TM. The example over the Angore anticline illustrates the inadequacy of 1D inversion in structurally complex geology complicated by electrical statics. Four MT lines along the Angore anticline have been interpreted using 2D inversion. Three-dimensional modelling has been used to simulate 3D statics in an otherwise 2D earth. These data were used to test the Groom-Bailey (GB) decomposition for possible benefits in reducing static effects and estimating geoelectric strike in the Papua New Guinea (PNG) field data. It has been found that the GB decomposition can provide improved regional 2D strike estimates in 3D contaminated data. However, in situations such as PNG, where the regional 2D strike is well established and hence can be fixed, the GB decomposition provides apparent resistivities identical to those simply rotated to strike.

    Thermogenic natural gases in Papua New Guinea occur in hanging wall anticlines and related structures along a 160 mile section of the Papuan fold and thrust belt between S.E. Hedinia in the SE and Pnyang in the NW. Isotopic compositions of the oil associated gases in the SE between Hedinia and Mananda varies little ([delta][sup l3]C[sub CH4]=-44[+-]2[per thousand] and [delta]D[sub CH4]=-200[+-]20[per thousand]). However, subtle isotopic and compositional patterns in these gases are structurally controlled and indicate primary differences in the filling history of the individual structures. In addition, secondary redistribution of the gases between the Agogo and Iagifu structure can be traced through isotopic similarities. In S.E. Mananda, however, gas isotope patterns are affected by bacterial degradation of the gas. Tire concentration of CO[sub 2] in the oil associated gases in the SE is low (0.6-3.0 %) and the carbon isotope values ([delta][sup 13]C[sub CO2]=-10 to -19[per thousand]) suggest an organic origin with minor inorganic contributions. Gas in the Juha structure ([delta][sup 13]C[sub CH4]=-36.8[per thousand]) is likely from a more mature source and has a CO[sub 2] concentration of 9.6% with a [delta][sup 13]C[sub CO2]=-5.9[per thousand], indicating additional CO[sub 2] generating processes in this area, likely related to magmatic activity in the vicinity of the Juha structure. The Pnyang structure in the NW of the area holds a gas ([delta][sup 13]C[sub CH4]-40.5[per thousand]) which is isotopically intermediate between the Juha gas and the oil associated gases in the SE. The low CO[sub 2] concentration of 0.2% suggests that Pnyang is sourced from a gas kitchen similar to, but more mature than, the kitchen for the oil associated gases in the SE of the province. This is consistent with the high GOR in this structure and the association of the gas with a high API gravity condensate.

    West Papua region has fairly high of seismicity activities due to tectonic setting and many inland faults. In addition, the region has a unique and complex tectonic conditions and this situation lead to high potency of seismic hazard in the region. The precise earthquake hypocenter location is very important, which could provide high quality of earthquake parameter information and the subsurface structure in this region to the society. We conducted 1-D P-wave velocity using earthquake data catalog from BMKG for April, 2009 up to March, 2014 around West Papua region. The obtained 1-D seismic velocity then was used as input for improving hypocenter location using double-difference method. The relocated hypocenter location shows fairly clearly the pattern of intraslab earthquake beneath New Guinea Trench (NGT). The relocated hypocenters related to the inland fault are also observed more focus in location around the fault.

    The Gobe 4X sidetrack exploration well was drilled in a remote area of the Southern Highlands Province of Papua New Guinea using an innovative sidetrack technique for delineating hydrocarbons. After gas was encountered in the Gobe 4X straight hole, a nonconventional sidetrack was drilled down dip along the bedding plane of the reservoir sand and determined the gas-oil contact and the oil-water contact with a single wellbore thereby establishing the limits of the oil band. This was accomplished despite a difficult well trajectory, high deviation angle, large stepout and limited structural information.

    1987-06-01

    In recent years, many rural Third World communities have suffered from the gradual degradation of the natural resources on which they depend. The Kilenge of the West New Britain, Papua New Guinea, offer such an example. The paper examines some of the nutritional, economic, social, and political impacts of these changes on the individual, on the household, and on the community in one Kilenge village. It argues that there may be alternatives to dependent development for this community. It concludes that redirected priorities can assist indigenous communities like Kilenge to achieve sustainable self-directed economic improvement.

    Over the past six years the Papua New Guinea Telecommunications network has expanded considerably necessitating the requirements for high reliability power supplies for mountain top repeater sites and small capacity telephone exchange terminals in remote locations. Photovoltaic (solar) power systems are considered the most suited for these applications. Furthermore, new microwave systems and large trunk VHF systems are now being installed. This paper discusses these photovoltaic power supplies in detail with respect to their design, technical composition, configuration with reference to performance and installation requirements.

However, the exact consequences of westernization on community characteristics are still insufficiently understood, and the ecological processes that drive differences have not been elucidated. Here we have compared the fecal microbiota of adults from two non-industrialized regions in Papua New Guinea (PNG) with that of United States (US) residents.

This analysis demonstrated a significant higher rate of bacterial dispersal in PNG and divergent selective environments in the US.

  2. Tectonic controls on carbonate platform evolution in southern Papua New Guinea: Passive margin to foreland basin

    1989-03-01

    The middle Oligocene collision of the northern margin of the Australian craton with a complex subduction system resulted in emplacement of a thrust mass and formation of a foreland basin that extended from the Coral Sea to the Indian Ocean. The distribution of carbonate-platform facies in southwestern Papua New Guinea reflects the transition from an Eocene passive margin setting to the early stages of foreland basin evolution. The initial basin configuration, with terrigenous sedimentation confined to the proximal foredeep, allowed carbonate deposition in the shallow environment adjacent to the peripheral forebulge. Subsequent southward migration of the basin resulted in a rapid increase in the area and thickness of carbonate-platform deposition. When the proximal foredeep became filled by detritus shed from the emerging orogen, clastic sediments buried the platform and terminated carbonate deposition. The history of the southern Papua New Guinea carbonate platform illustrates the paradox of carbonate deposition within the foreland basin, whereby basin configuration initially encourages thick and extensive carbonate deposition but inevitably leads to terrigenous inundation and the demise of the carbonate platform.

By combining offshore seismic data from the Solomon Sea with geologic mapping in the Markham Valley area of northern Papua New Guinea the authors are predicting the outcome of this collision. The Huon Gulf is the present site of initial collision. Seismic profiles show this area is dominated by thin thrust sheets. Onshore, the bulk of the uplifted accretionary wedge is a melange with exotic blocks of a variety of lithologies. Structurally below the melange lies the Leron Formation composed of thick channelized sandstone and conglomerate. It dips north at approximately 40{degree} and is cut by several thrust fault with associated folds. Limestone blocks within the melange are reported to be 2 Ma, and Beryllium 10 anomalies from Bismarck arc volcanoes suggest that initial collision of the Finisterre block (375 km northwest of the present collision point) began no earlier than 3 Ma. This implies the collision is propagating laterally at about 125 km/m.y.. Large outcrops of basalt and gabbro within the melange suggest that segments of oceanic crust were incorporated into the accretionary wedge. Modern sedimentation within the collision zone grades from fluvial sediments in the Markham Valley to deep-water turbidites ponded behind a structural ridge near the point of incipient collision. The Markham submarine canyon occupies the collision front here, and efficiently erodes the accretionary wedge. This setting may serve as a modem analog for deposition of much of the Leron Formation which exhibits tremendous sediment reworking.

    It is important to understand gender difference on pesticide use knowledge, attitude and practices for identifying pesticide risks by gender and to recommend more gender-sensitive programs. However, very few studies have been conducted so far in Nepal. This study, thus, interviewed a total of 325 males and 109 females during 2005 to assess gender differences on pesticide use knowledge, attitude and practices. More than 50% females had never been to school and only <8% individuals were found trained in Integrated Pest Management (IPM). Almost all males and females did not smoke, drink and eat during pesticides application and also believed that pesticides are harmful to human health, livestock, plant diversity and their environment. However, there were gender differences on household decision on pesticides to be used (p<0.001), care of wind direction during spraying (p=0.032), prior knowledge on safety measures (p=0.016), reading and understanding of pesticides labels (p<0.001), awareness of the labels (p<0.001) and protective covers. Almost all respondents were aware of negative impacts of pesticide use on human health and environment irrespective of gender; however, females were at higher risk due to lower level of pesticide use safety and awareness. It is strongly recommended to initiate gender-sensitive educational and awareness activities, especially on pesticide use practices and safety precautions.

    Chevron Nuigini Pty Ltd. and its partners are exploring for oil in the foreland folded belt of Papua New Guinea's Southern Highlands province, one of the remaining frontier areas of the world that offers the potential for the discovery of giant oil fields. The search has been focused on the Lower Cretaceous Toro sandstone, an excellent reservoir rock unit about 100 m thick. It is overlain by up to 1,200 m of Upper Cretaceous marine shales, siltstones, and fine sandstones (Ieru formation) and, finally, at the surface by the thick (1,000 m) Miocene Darai limestone. The entire stratigraphic sequence was folded during the Pliocene-Pleistocene into a broad belt of thrusted anticlines that have good surface expression throughout the highland valleys and ridges. The thick carapace of folded limestone is heavily karsted and extremely rugged, circumstances that have prohibited effective seismic surveying of the region. Prospecting for oil has consequently relied almost entirely on structural interpretation of surface geologic data, including images from satellites and airborne radar, and, most particularly, on the results of wildcat drilling. Fortunately, early drilling was rewarded with encouraging quantities of gas, gas condensate, and oil. Structural models and concepts are continuing to evolve as the results of successive wells become available, thus providing the critical insight into the habitat of hydrocarbons in this complex environment.

    Selenium intakes of 66 rural Malawian children aged 4-6 y consuming maize-based diets were compared with those of 67 Papua New Guinea (PNG) children aged 6-10 y with diets based on bananas, sweet potatoes, and sago. Representative samples of all staple foods consumed were collected, dried, ground and subsequently analyzed for Se by instrumental neutron activation analysis using {sup 77}Se. Median Se intakes for the Malawian children determined by weighed 3-day records at 3 seasons of the year were: harvest 20 {mu}g/d, 1.24 {mu}g/kg; postharvest 21 {mu}g/d, 1.24 {mu}g/kg; preharvest 15 {mu}g/d, 0.96 {mu}g/kg. For the PNG children the median intake during the rainy season, assessed from two 24 hr interactive recalls, was 20 {mu}g/d, 0.89 {mu}g/kg. Four food groups contributed to {ge}95% of the total Se intake for both the Malawian and the PNG children. Of the children, 55% of the Malawian and 87% of the PNG had average Se intakes {lt} US Recommended Dietary Allowances (RDA); 16% and 48% respectively, had intakes {lt}66% US RDA. Average Se intakes were below those reported for US and Australian children but above those of children from New Zealand where Se intakes are low.

    More than 800 Magnetotelluric (MT) stations and EMAP dipoles have been acquired in Papua New Guinea (PNG) since 1988. The use and understanding of this non-seismic method has developed because the lucrative petroleum province of the Highlands Fold Belt. Exploration in this area precludes conventional seismic acquisition owing to outcropping limestone which is karstified and more than 3000 feet (1 km) thick in most areas. MT acquisition has expanded from acquiring single-site or dual-site data using standard wire-link communication to acquiring five stations simultaneously, with communications via radio telemetry. This has resulted in higher production rates, better quality data, and more flexible emplacement of station locations. Design modifications to acquisition equipment has resulted in lighter gear which acquires data with higher signal-to-noise ratio, leading to more reliable interpretations. Advances in computer modeling, primarily through Geotools software, along with better understanding of the structural province and integration with geologists` information, have improved the usability of the interpreted data. The last seven years have seen several wells drilled of which many are now in production. MT has been acquired at many of these locations, and continues to be a advanced exploration tool. Case histories will demonstrate the effectiveness of exploration using MT and other electrical methods.

  10. Petroleum systems of the Papuan Basin, Papua New Guinea, and their exploration potential

    1995-08-01

    The Papuan Basin of Papua New Guinea is a mature basin with a complex geologic history. The basin was initiated during Permo-Triassic rifting of the northern margin of Australia. Passive margin sedimentation occurred until the Oligocene to Recent when the basin was compressionally inverted, resulting in the formation of the present-day fold and thrust belt. Numerous hydrocarbon fields, some commercial, occur in traps along the front of the thrust belt. In mature complex basins such as this, it is critical to fully characterize existing petroleum systems as well as deliberately search for new systems. A recent systematic synthesis of the available geochemical data has defined three systems. Most important is the Jurassic system which is responsible for most of the oil and gas fields and all commercial production. Cretaceous and Tertiary systems, newly discovered in the basin, are based on detailed isotope and biomarker analysis of numerous oil seep. These additional petroleum systems open up new plays for exploration. To better define the pre-thrust basin geometry and help constrain the timing of hydrocarbon generation and migration, a series of palinspastically-stored cross-sections were constructed. Maturity modelling at different basin locations along these cross-sections evaluated the relative importance of two important species: (1) pre-thrust generation from local kitchens behind the present thrust belt, and (2) syn-thrust generation by loading of stacked thrust sheets within the fold belt. The relative importance of re-migration from pre-thrust traps vs direct charging into present day fold belt traps was evaluated using oil composition data.

    Synthetic aperture radar (SAR) is being successfully used within the southern fold and thrust belt of Papua New Guinea to map surface structure and stratigraphy and to help plan a hydrocarbon exploration program. The airborne SAR imagery, along with other surface data, is used as a primary exploration tool because acquisition of acceptable seismic data is extremely costly due to extensive outcrops of Tertiary Darai Limestone which develops rugged karst topography. Most anticlines in the licenses are capped with this deeply karstified limestone. The region is ideally suited to geologic analysis using remote sensing technology. The area is seldom cloud free and is covered with tropical rain forest, and geologic field studies are limited. The widespread karst terrain is exceedingly dangerous, if not impossible, to traverse on the ground. SAR is used to guide ongoing field work, modeling of subsurface structure, and selection of well locations. SAR provides their explorationists with an excellent data base because (1) structure is enhanced with low illumination, (2) resolution is 6 x 12 m, (3) digital reprocessing is possible, (4) clouds are penetrated by the SAR, and (5) the survey was designed for stereoscopic photogeology. Landsat images and vertical aerial photographs complement SAR but provide subdued structural information because of minimal shadowing (due to high sun angles) and the jungle cover. SAR imagery reveals large-scale mass wasting that has led to a reevaluation of previously acquired field data. Lithologies can be recognized by textural and tonal changes on the SAR images despite near-continuous canopy of jungle. Reprocessing and contrast stretching of the digital radar imagery provide additional geologic information.

  12. Petroleum prospects for offshore sedimentary basins in the eastern Papua New Guinea and Solomon Islands regions

    Intra-arc basins in the Buka-Bougainville region of Papua New Guinea and in the Solomon Islands contain thick sedimentary sequences that may be prospective for petroleum. The Queen Emma basin, between Bougainville and New Ireland, contains as much as 8 km of deformed Oligocene and younger strata. The Central Solomons Trough, which underlies New Georgia Sound, is a composite intra-arc basin that contains late Oligocene and younger strata as much as 7 km thick. Farther east, beneath Indispensable Strait, the down-faulted Indispensable basin locally contains as much as 5.4 km of Miocene( ) and younger strata, and the offshore part of Mbokokimbo basin off eastern Guadalcanal includes 6 km or more of late Miocene and younger strata. All of these basins have some of the attributes necessary to generate and trap petroleum. Structural and stratigraphic traps are common, including faulted anticlines, sedimentary wedges, and carbonate reefs and reef-derived deposits on submarine ridges and along the basin margins. The thickness of the basin deposits ensures that some strata are buried deeply enough to be within the thermal regime required for hydrocarbon generation. However, little source or reservoir rock information is available because of the lack of detailed surface and subsurface stratigraphy. Moreover, much of the basin sediment is likely to consist of volcaniclastic material, derived from uplifted volcanogenic rocks surrounding the basins, and may be poor in source and reservoir rocks. Until additional stratigraphic information is available, analysis of the petroleum potential of these basins is a matter of conjecture.

  13. Structure of Papuan foldbelt, emerging hydrocarbon province in Papua New Guinea

    The 500-km long, northwest-southeast-trending, Mio-Pliocene foldbelt of west-central Papua New Guinea is part of an extensive 2000-3000-m high mountain belt through New Guinea that is similar in structural style to the Canadian Rockies. The southwesterly thrust-faulted sediments of the foldbelt are bound to the northeast by major sinistral wrench faults, with allochthonous metamorphic terranes to the north. The sedimentary section comprises 3-4 km of Mesozoic clastics, containing the main hydrocarbon reservoir, overlain by 1-1.5 km of Tertiary limestone. The northeast two-thirds of the foldbelt has a Tertiary limestone duplex at surface and, by inference, Mesozoic duplex(es) beneath, with 70+ km of shortening. In the southwest foldbelt, there is considerable inversion of preexisting extensional faults and the limestone duplex is absent, implying deeper detachment. Shortening in the southwest was approximately 20 km. Along strike, the foldbelt is divided into three segments by major regional lateral ramps. These ramps connect areas with different basal detachments, particularly in the southwest. The northwest segment decollement is 10-12 km into basement along the mid-crustal detachment. The resultant 200-km long Mueller anticline exposes basement in the core and is prospective for hydrocarbons in the parasitic structures, such as the Juha gas-condensate field. The central segment prospective structures, such as the Mananda and Hides anticlines, are detached just above basement such that the entire sedimentary section is repeated. The southeast segment detachment is within the Mesozoic, but the structures, such as the Iagifu oil field, involve the sandstone reservoir and are prospective.

    The SiO{sub 2}-undersaturated lavas from Lihir island, Papua New Guinea, like most arc lavas are highly enriched in Sr, Ba, K, Rb, and Cc and depleted in Hf, Ta, Nb, and Ti relative to ocean floor basalts and oceanic island basalts. These alkali-rich lavas have arc trace element signatures and Nd, Sr, and Pb isotopic systematics. However, they are not a product of present-day subduction, as this volcanism has tapped mantle which was enriched by prior subduction episodes. The narrow range of Pb isotopic compositions suggest a cogenetic origin for these lavas. During the fractionation of the primitive Lihir lavas, elements normally considered incompatible (i.e., the light rare earth elements (LREE), Rb, Th, and P) have high bulk solid/melt partition coefficients (0.15-1.5). Relatively higher partition coefficients during formation of the evolved lavas produced crossing rare earth element (REE) patterns, and primitive lavas have higher incompatible elements abundances than evolved lavas. The Lihir lavas have lower alkali, Sr, Ba, K, Rb, Cs, and LREE abundances than other Tabar-Feni lavas. They are derived from a less enriched mantle source rather than by a higher degree of melting of a source similar to that of the other islands. The similarity of Sm/Nd ratios of these undersaturated arc lavas to those of tholeiitic and calc-alkaline arc lavas and the moderate chondrite-normalized La/Yb (la/Yb{sub cn} = 3-7) indicates that there has been limited enrichment of the LREE relative to the heavy REE during generation of the arc-modified source mantle. The alkaline nature of these lavas reflects their generation, in a tensional tectonic environment, from a fossil arc mantle region that has undergone extreme arc enrichment of alkali and alkaline earth elements during two earlier subduction episodes.

    The unprecedented level of support that has been pledged to strengthen Government of Papua New Guinea (GoPNG) biodiversity conservation initiatives has re-identified an important fact that technical and infrastructure support must be complemented by programs that provide realistic opportunities for developing national capacity. Indications are that the next five years will present a range of challenging opportunities for the department to move from the intensive period of planning, which has been the focus of attention during the first phase of the National Forestry and Conservation Action Programme (NFCAP), into a sustained period of policy and project application. This paper examines processes under which strengthening programs contribute to national development objectives and complement accomplishment of the Department of Environment and Conservation Strategic Plan. An overview of the Global Environment Facility-Integrated Conservation and Development (ICAD) Project and coordination effort that are being made for biodiversity conservation projects in Papua New Guinea, are addressed.

  18. Heat flow and geothermal gradients of Irian Jaya-Papua New Guinea: Implications for regional hydrocarbon exploration

    Compilation of published and unpublished bottom hole temperatures (corrected for circulation times) obtained from open files and reports of the Indonesian Petroleum Association, Papua Geologic Survey, and the Southeast Asia Petroleum Society, together with published oceanographic heat flow analyses from the surrounding seas, allow an analysis of the regional heat flow and geothermal gradients of New Guinea. In two dimensions the thermal trends may be described as a pervasive west-northwest striking Cordilleran core of cool (<1 HFU-<2{degree}C/ 100 m) strata surrounded by warm to hotter regions (>2 HFU->4{degree}C/100 m) on the northwest, northeast, east, and southwest. As a first approximation, the heat flow may be viewed as directly proportional to the crustal thickness (as demonstrated from north-south transects across the Central Cordillera), inversely proportional to the age of the ocean crust (offshore), and perturbed by crustal heterogeneities proximal to plate boundaries (e.g., the Northern New Guinea Fault System). As a result, the heat flow distribution affords a record of post-Cretaceous tectonic activities of New Guinea. Using the spatial distribution of geothermal gradients and specific source rock ages, kinetic calculations of hydrocarbon maturities confirmed by recent drilling results suggest thermal variations through space and time that cannot be modeled simply as a function of present day static temperatures. Therefore, in terms of utilizing the present thermal information, hydrocarbon basin exploration strategies must also take into account the tectonically perturbed heat flow history of the region.

    Over the years several types of remote sensing surveys have been acquired of the Eastern Papuan Fold Belt, in the Gulf Province of Papua New Guinea. These include aerial photographs, Landsat Multispectral Scanner (MSS), and Synthetic Aperture Radar (SAR). Each has been used by Petro-Canada Inc. for interpreting the geologic structure and stratigraphy of onshore hydrocarbon prospects. Analysis of available remotely sensed imagery reveals greater structural complexity than is shown on published geologic maps. Foremost among the images is SAR because of its low, artificial sun angle. Hence, a comprehensive view of the area has been acquired revealing many structural elements previously not appreciated. A distinct difference in structural style is found between the northern and southern segment of the Eastern Papuan fold belt in the study area. The northern segment shows discontinuous, open folds with widely separated anticlines set in featureless valleys. The southern segment is tightly folded, possessing few anticlines and synclines clearly recognizable on the imagery. However, structural components can be traced easily for tens of miles. Recent field work supports an SAR structural interpretation suggesting most, if not all, anticlines in the northern segment are overturned. The combination of remote sensing and field work proved invaluable in understanding the fold belt tectonics and has aided considerably in the selection of drilling locations.

    The Porgera gold deposit is spatially and temporally associated with the Late Miocene, Mafic, alkalic, epizonal Porgera Intrusive Complex (PIC), located in the highlands of Papua New Guinea (PNG). The highlands region marks the site of a Tertiary age continent-island-arc collision zone, located on the northeastern edge of the Australasian craton. It is suggested that the hydrothermal fluids acquired their Sr and Pb isotopic signatures by interaction with, or direct derivation from, a plutonic root of the PIC and host sedimentary rocks of the Om Formation. It is likely that Au was also derived from one or both of these two sources. Concentrations of Au in unaltered igneous and sedimentary rocks from Porgera ({le}10 ppb Au) do not indicate that either lithology represents a significantly enriched protore, although Au and platinum-group element (PGE) abundances in the igneous rocks suggest a mild primary magmatic enrichment of Au relative to the PGE (average (Au/(Pt+Pd)) {sub mantle normalized} = 14.0 {plus minus} 6.5 (n = 8)). Evidence that the Porgera magmas were rich in volatiles permits speculation that Au may have been concentrated in a magmatic fluid phase, but alternative possibilities such as derivation of Au by hydrothermal leaching of solidified igneous materials or sedimentary rocks cannot be excluded at this time.

  1. Atmospheric Radiation Measurement (ARM) Data from Niamey, Niger for the Radiative Atmospheric Divergence using AMF, GERB and AMMA Stations (RADAGAST)

    DOE Data Explorer [Office of Scientific and Technical Information (OSTI)]

    The Atmospheric Radiation Measurement (ARM) Program is the largest global change research program supported by the U.S. Department of Energy. The primary goal of the ARM Program is to improve the treatment of cloud and radiation physics in global climate models in order to improve the climate simulation capabilities of these models. To achieve this goal, ARM scientists and researchers around the world use continuous data obtained through the ARM Climate Research Facility. The ARM Mobile Facility (AMF) operates at non-permanent sites selected by the ARM Program. Sometimes these sites can become permanent ARM sites, as was the case with Graciosa Island in the Azores. It is now known as the Eastern North Atlantic permanent site. In January 2006 the AMF deployed to Niamey, Niger, West Africa, at the Niger Meteorological Office at Niamey International Airport. This deployment was timed to coincide with the field phases and Special Observing Periods of the African Monsoon Multidisciplinary Analysis (AMMA). The ARM Program participated in this international effort as a field campaign called "Radiative Divergence using AMF, GERB and AMMA Stations (RADAGAST).The primary purpose of the Niger deployment was to combine an extended series of measurements from the AMF with those from the Geostationary Earth Radiation Budget (GERB) Instrument on the Meteosat operational geostationary satellite in order to provide the first well-sampled, direct estimates of the divergence of solar and thermal radiation across the atmosphere. A large collection of data plots based on data streams from specific instruments used at Niamey are available via a link from ARM's Niamey, Niger site information page. Other data can be found at the related websites mentioned above and in the ARM Archive. Users will be requested to create a password, but the plots and data files are free for viewing and downloading. The ARM Archive physically resides at the Oak Ridge National Laboratory.

    The extensive flight of uplifted reef terraces which occurs along the Vitiaz strait on the northern flank of the Huon Peninsula in PNG (Papua New Guinea) contains a particularly good record of sea level changes in the last 250 ky. The Huon terraces were the target of an international expedition which took place in July--August 1988. In particular, the authors searched for suitable samples for U-series dating in a reef complex designated as VII, which is correlated with the last interglacial episode and high sea level stand. This complex is composed of a barrier reef (VIIb), a lagoon, and a fringing reef (VIIa). Twelve corals from these terraces and two corals from the older reef complex VIII were selected for analysis. The petrography, oxygen and carbon isotope compositions, and magnesium and strontium concentrations were determined along with the concentrations and isotopic compositions of uranium and thorium. The simplest model for sea level height for terrace VII is a continuous rise between 134 and 118 ky. Alternatively, there may have been two periods of rapid sea level rise. In contrast, in the Bahamas, there is evidence that sea level remained rather constant over the time interval 132 to 120 ky. The absence of ages between 132 and 120 ky in PNG could be the result of changes in the local tectonic uplift rates during that time, or erosion that disrupted the continuous record. In any event, the authors find no basis for accepting a single brief time for the age of the last interglacial and applying this age as a precise chronometer for worldwide correlation, or as a test of climatic models. The older ages reported here precede the Milankovitch solar insolation peak at 128 ky, and the younger ages are [approximately]10 ky after this peak. If the present high-precision data are correct, then it will be necessary to reassess the validity of the Milankovitch theory of climatic changes. 76 refs., 6 figs., 6 tabs.

    The filamentous fungus Aspergillus niger exhibits great diversity in its phenotype. It is found globally, both as marine and terrestrial strains, produces both organic acids and hydrolytic enzymes in high amounts, and some isolates exhibit pathogenicity. Although the genome of an industrial enzyme-producing A. niger strain (CBS 513.88) has already been sequenced, the versatility and diversity of this species compels additional exploration. We therefore undertook whole genome sequencing of the acidogenic A. niger wild type strain (ATCC 1015), and produced a genome sequence of very high quality. Only 15 gaps are present in the sequence and half the telomeric regions have been elucidated. Moreover, sequence information from ATCC 1015 was utilized to improve the genome sequence of CBS 513.88. Chromosome-level comparisons uncovered several genome rearrangements, deletions, a clear case of strain-specific horizontal gene transfer, and identification of 0.8 megabase of novel sequence. Single nucleotide polymorphisms per kilobase (SNPs/kb) between the two strains were found to be exceptionally high (average: 7.8, maximum: 160 SNPs/kb). High variation within the species was confirmed with exo-metabolite profiling and phylogenetics. Detailed lists of alleles were generated, and genotypic differences were observed to accumulate in metabolic pathways essential to acid production and protein synthesis. A transcriptome analysis revealed up-regulation of the electron transport chain, specifically the alternative oxidative pathway in ATCC 1015, while CBS 513.88 showed significant up-regulation of genes relevant to glucoamylase A production, such as tRNA-synthases and protein transporters. Our results and datasets from this integrative systems biology analysis resulted in a snapshot of fungal evolution and will support further optimization of cell factories based on filamentous fungi.[Supplemental materials (10 figures, three text documents and 16 tables) have been made available

    A sequence stratigraphic model developed from the ancient Rio Grande Delta in South West Texas is suggested as an analog for the Niger Delta. The two delta systems are characterized by high sand bedloads, shale diapirism with associated listric normal faulting, and large amounts of tidal and wave influence forming lower coastal plains characterized by swamps and estuaries. The sequence stratigraphic model of the ancient Rio Grande delta is based on approximately 1200 kilometers of single channel, 15 cubic inch water gun data, lithologic descriptions from approximately 25 long cores (28-30 m) located in 17-94 meters water depth, three gamma ray logs, paleontologic data from two cores, and oxygen isotopic data from one core (152 meters in length and located in 94 meters water depth). The combined data indicate that considerable quantities of sand are sequestered on the continental shelf and point sourcing the slope. The Rio Grande sequence stratigraphic model provides an improved understanding of sand deposits on the shelf, of the role of sediment bypass during lowstands, and of the base of slope deposits formed by headward eroding canyons (?) or channels (?) located at the shelf break. This information regarding the distribution of sand in the Rio Grande system can provide valuable insight into the reservoir distribution in the Niger system, improving existing reservoir predictions.

    The identification of extremely high indoor radon concentrations in the village Umhausen (Tyrol, Austria) initiated a scientific program to get information about the source and distribution of this noble gas. The high concentrations can not be related to U anomalies or large-scale fault zones. The nearby giant landslide of Koefels, with its highly fractured and crushed orthogneisses, are the only possible source of radon, despite the fact that the U and Ra content of the rocks is by no means exceptional. The reasons for the high emanation rates from the landslide are discussed and compared to results gained from a similar examination of the giant landslide of Langtang Himal (Nepal). The exceptional geologic situation in both cases, as well as the spatial distribution of different concentration levels, indicate that both landslides must be considered as the production sites of radon. Independent of the U and Ra contents of the rocks, the most important factors producing high emanation rates are the production of a high active surface area in circulation pathways for Rn-enriched soil air by brittle deformation due to the impact of the landslidemass. 37 refs., 4 figs., 1 tab.

    Protein glycosylation is known to play an essential role in both cellular functions and the secretory pathways; however, little information is available on the dynamics of glycosylated N-linked glycosites of fungi. Herein we present the first extensive mapping of glycosylated N-linked glycosites in industrial strain Aspergillus niger by applying an optimized solid phase enrichment of glycopeptide protocol using hydrazide modified magnetic beads. The enrichment protocol was initially optimized using mouse plasma and A. niger secretome samples, which was then applied to profile N-linked glycosites from both the secretome and whole cell lysates of A. niger. A total of 847 unique N-linked glycosites and 330 N-linked glycoproteins were confidently identified by LC-MS/MS. Based on gene ontology analysis, the identified N-linked glycoproteins in the whole cell lysate were primarily localized in the plasma membrane, endoplasmic reticulum, golgi apparatus, lysosome, and storage vacuoles. The identified N-linked glycoproteins are involved in a wide range of biological processes including gene regulation and signal transduction, protein folding and assembly, protein modification and carbohydrate metabolism. The extensive coverage of glycosylated N-linked glycosites along with identification of partial N-linked glycosylation in those enzymes involving in different biochemical pathways provide useful information for functional studies of N-linked glycosylation and their biotechnological applications in A. niger.

    The accuracy of earthquake hypocenter position is necessary to analyze the tectonic conditions. This study aims to: (1) relocate the mainshock and aftershocks of the large earthquakes in Papua region i.e. June 16, 2010, April 21, 2012 and April 06, 2013 earthquake (2) determine the true fault plane, (3) estimate the area of the fracture, and (4) analyze the advantages and disadvantages of relocation with MJHD method in benefits for tectonic studies. This study used Modified Joint Hypocenter Determination (MJHD) method. Using P arrival phase data reported by the BMKG and openly available from website repogempa.bmkg.go.id, we relocated the mainshock of this large significant earthquake and its aftershocks. Then we identified the prefered fault planes from the candidate fault planes provided by the global CMT catalogue. The position of earthquakes was successfully relocated. The earthquakes mostly were clustered around the mainshock. Earthquakes that not clustered around mainshock are considered to be different mechanism from the mainshock. Relocation results indicate that the mainshock fault plane of June 16, 2010 earthquake is a field with strike 332o, dip 80o and −172o slip, the mainshock fault plane of April 21, 2012 earthquake is a field with strike 82o, dip 84o and 2o slip, the mainshock fault plane of April 06, 2013 earthquake is a field with strike 339o, dip 56o and −137o slip. Fault plane area estimated by cross section graphical method is an area of 2816.0 km2 (June 16, 2010), 906.2 km2 (April 21, 2012) and 1984.3 km2 (April 06, 2013). MJHD method has the advantage that it can calculate a lot of earthquakes simultaneously and has a station correction to account for lateral heterogeneity of the earth. This method successfully provides significant changes to improve the position of the depth of earthquakes that most of the hypocenter depth manually specified as a fixed depth (± 10 km). But this method cannot be sure that the hypocenters derived from the

    The asexual filamentous fungus Aspergillus niger is an important industrial cell factory for citric acid production. In this study, we genetically characterized a UV-generated A. niger mutant that was originally isolated as a nonacidifying mutant, which is a desirable trait for industrial enzyme production. Physiological analysis showed that this mutant did not secrete large amounts of citric acid and oxalic acid, thus explaining the nonacidifying phenotype. As traditional complementation approaches to characterize the mutant genotype were unsuccessful, we used bulk segregant analysis in combination with high-throughput genome sequencing to identify the mutation responsible for the nonacidifying phenotype. Since A. niger has no sexual cycle, parasexual genetics was used to generate haploid segregants derived from diploids by loss of whole chromosomes. We found that the nonacidifying phenotype was caused by a point mutation in the laeA gene. LaeA encodes a putative methyltransferase-domain protein, which we show here to be required for citric acid production in an A. niger lab strain (N402) and in other citric acid production strains. The unexpected link between LaeA and citric acid production could provide new insights into the transcriptional control mechanisms related to citric acid production in A. niger. Interestingly, the secondary metabolite profile of a ΔlaeA strain differed from the wild-type strain, showing both decreased and increased metabolite levels, indicating that LaeA is also involved in regulating the production of secondary metabolites. As a result, we show that our systems genetics approach is a powerful tool to identify trait mutations.

    An aeromagnetic contour map compiled over shallow water and onshore portions of the Nigerian continental margin, shows several elongate, long-wavelength anomaly closures with some alternating polarity, separated by steep gradient, NE lineations. The lineations are interpreted as new fracture zones or extensions of previously mapped ones. The NE trend in the western delta region is concordant with the fracture zone trends of the deeper Gulf of Guinea. Aeromagnetic lineations of the SE Niger Delta Basin however, discordantly trend ENE. Their termination against the former, is interpreted as evidence of early sea-floor spreading in a ENE-WSW direction in addition to the well documented NE-SW spreading of the Gulf of Guinea and the rest of the meso-Atlantic sea-floor; The geophysical crustal structure indicate the existence of two Early Cretaceous triple junctions beneath the Niger Delta Basin. The two triple-junctions further support the hypothesis that the African continent was a multi-plate system (in the Niger Delta region) during the early opening of the Atlantic.

  11. Expression of the Aspergillus niger InuA gene in Saccharomyces cerevisiae permits growth on the plant storage carbohydrate inulin at low enzymatic concentrations

    2015-01-01

    The plant storage carbohydrate inulin represents an attractive biomass feedstock for fueling industrial scale bioconversion processes due to its low cost, ability for cultivation on arid and semi-arid lands, and amenability to consolidated bioprocessing applications. As a result, increasing efforts are emerging towards engineering industrially relevant microorganisms, such as yeast, to efficiently ferment inulin into high value fuels and chemicals. Although some strains of the industrially relevant yeast model Saccharomyces cerevisiae can naturally ferment inulin, the efficiency of this process is often supplemented through expression of exogenous inulinase enzymes that externally convert inulin into its more easily fermentable component monomericmore » sugars. Here, the effects of overexpressing the Aspergillus niger InuA inulinase enzyme in an S. cerevisiae strain incapable of endogenously fermenting inulin were evaluated to determine their impact on growth. Expression of the A. niger InuA inulinase enzyme permitted growth on otherwise intractable inulin substrates from both Dahlia tubers and Chicory root. Despite being in the top 10 secreted proteins, growth on inulin was not observed until 120 h post-inoculation and required the addition of 0.1 g fructose/l to initiate enzyme production in the absence of endogenous inulinase activity. High temperature/pressure pre-treatment of inulin prior to fermentation decreased this time to 24 h and removed the need for fructose addition. The pre-growth lag time on untreated inulin was attributed primarily to low enzymatic efficiency, with a maximum value of 0.13 0.02 U InuA/ml observed prior to the peak culture density of 2.65 0.03 g/l. Nevertheless, a minimum excreted enzymatic activity level of only 0.03 U InuA/ml was found to be required for sustained growth under laboratory conditions, suggesting that future metabolic engineering strategies can likely redirect carbon flow away from inulinase production and reorient

    Mesothermal/epithermal gold mineralization at Porgera in the highlands of Papua New Guinea (PNG), occurs in structurally controlled veins and disseminations, which overprint and cross-cut a suite of shallow-level, comagmatic, mafic alkaline stocks and dykes and their sedimentary host rocks. Conventional K-Ar apparent ages of twelve hornblende separates from eight different intrusions scatter between 7 and 14 Ma, but four biotite separates are concordant at 6.02 {plus minus} 0.29 Ma (2{sigma}). {sup 40}Ar/{sup 39}Ar step-heating experiments on six of the hornblende separates reveal saddle-shaped age spectra, which indicate the presence of excess {sup 40}Ar. One of these samples yields a well-defined plateau with an apparent age of 5.96 {plus minus} 0.25 Ma (2{sigma}). Conventional K-Ar analyses of six separates of hydrothermal illite and roscoelite associated with gold mineralization yield apparent ages of between 5.1 and 6.1 Ma and indicate that ore deposition occurred within 1 Ma of magmatism at Porgera. Evidence for the evolution of a magmatic volatile phase, and the presence of excess {sup 40}Ar both in the intrusives and in hydrothermal fluids associated with the orebody, suggest that magmatic fluids may have had some involvement in metallogenesis, but the exact nature of this involvement is not yet clear. Late Miocene magmatism and mineralization at Porgera are thought to have occurred shortly prior to or during the initiation of continent/arc collision and to pre-date associated Pliocene uplift and foreland deformation in the highlands.

    Jayapura city had destructive earthquake which occurred on June 25, 1976 with the maximum intensity VII MMI scale. Probabilistic methods are used to determine the earthquake hazard by considering all possible earthquakes that can occur in this region. Earthquake source models using three types of source models are subduction model; comes from the New Guinea Trench subduction zone (North Papuan Thrust), fault models; derived from fault Yapen, TareraAiduna, Wamena, Memberamo, Waipago, Jayapura, and Jayawijaya, and 7 background models to accommodate unknown earthquakes. Amplification factor using geomorphological approaches are corrected by the measurement data. This data is related to rock type and depth of soft soil. Site class in Jayapura city can be grouped into classes B, C, D and E, with the amplification between 0.5 – 6. Hazard maps are presented with a 10% probability of earthquake occurrence within a period of 500 years for the dominant periods of 0.0, 0.2, and 1.0 seconds.

    The prospectivity of the Papuan Basin has been appreciated, since oil seeps were first discovered in 1911. Initially, the mountainous terrain, a deeply karstified limestone surface covered with tropical rainforest, fed by 300 inches of rain each year, restricted access to the adventurous. Early exploration was focussed along the coastline and river systems, with only limited success. The development of helicopter transportable rigs during the 1970s was the technological advance that led to success, as the crests of anticlines became accessible to the drill. Even so, the lack of seismic due to severe terrain conditions and structural complexity, still constrains our ability to image trap. Despite these limitations, the oil discovery at Lagifu-2 in 1986, led to the development of the Kutubu Field by a Chevron led joint venture, with first oil in 1992. The Kutubu Field was developed at a cost of US$ 1 billion. Reserves are in excess of 250 mmbo with production currently at 1,00,000 bopd. PNG's second oil development will be the Gobe / SE Gobe Fields, also in the Papuan Thrust Belt, and thought to contain around 100 mmbo. Discovered in the late 1980s, the field is expected to produce 25 000 bopd from 1997. Significant volumes of gas have been discovered in the Highlands at Hides, where 3 wells have now confirmed a gas column in excess of 1 km. Additional large gas discoveries have been made in the Papuan Basin, highlighting the potential for PNG to become a long term LNG s producer.

    The Eocene Port Moresby beds consist of chert, siliceous argillite, and calcarenite in a 3000-m sequence. A northwest grain and severe topography at outcrop reflect 50/sup 0/-80/sup 0/ structural dips, northeastward-inclined, low-angle thrust faults, and high-angle reverse faults. Within the fault slices, symmetrical folds plunge toward the northwest, and syntaphral folds occur intermittently. The cherts are comprised of biogenic silica and rarer spherulitic, fibrous chalcedony in massive nodular concretions up to 2 m in diameter and as competent, repetitive, 10 to 30-cm thick beds. The calcarenites are richly nummulitic, partly silicified, and contain chert nodules. Radiolaria, planktonic foraminifera, and sponge spicules predominate over reworked fauna in the cherts. Microlaminations and sparse pyrite endorse the interpretation of sheltered, possibly deep, and rapid deposition in a reducing environment. Chert and cherty limestone crop out again, 200 km northwest at Hell's Gate, Saw Mountains. Oil and gas seeps in the intervening Lakekamu-Moresby Embayment were first recorded 75 years ago, and seismic interpretation confirms the presence of buried thrust folds. Gas and Oil fluorescence was recorded in four vintage wells, but none have tested the Eocene. Like the Monterey Formation, fractured radiolarian cherts have potential as a resource in terms of both reservoir and source. Moresby chert deposition is possibly related to opening of the Coral Sea. The chert diagenesis and thermal maturation were probably influenced by Paleogene overthrusting of oceanic crust 100 km east, Neogene uplift of the Mesozoic metamorphics in the 4000-m Owen Stanley Range, and consequential southwesterly detachment folding of the Tertiary section.

    The collision of the Finisterre-New Britain terrane with the Australian continent is propagating eastward at a rate of approximately 125 km/m.y., based on plate motions and the collisional geometry, as well as on the geochemistry of the arc volcanics. A sequence of sedimentary facies is developed from east to west in the modern environment (pelagic sediments, turbidites, marine molasse, and fluvial molasse), and this sequence is accreted from north to south at the front of the terrane collision in the Markham valley. Based on the modern distribution, the authors suggest that the age of the initial marine molasse will predate the passage of the collision point, and that of the fluvial molasse will postdate its passage. Intense erosion in the Markham canyon, located along the suture between the collision point and the coast, appears to be responsible for stripping most of the accreted marine molasse and redepositing it in a basin just east of the collision point. Convergence along the suture zone deceases westward. At Lae, very young deformation is seen, but 80 km to the west undeformed terrace deposits cover the deformation front. Uplift appears active within the range, aided by out-of-sequence thrusting, but still farther west the rocks lack signs of young tectonism. In the region just west of Lae, the main locus of slip between the Australian and south Bismarck plates must transfer southward to the front of the Papuan fold-and-thrust belt.

    A reservoir development plan was developed from a detailed geological model of the SE Gobe Iagifu reservoir. This model incorporated sequence stratigraphy and extensive core and log analysis to provide the detailed layering framework for reservoir simulation. Cross-sectional balancing techniques were applied to field derived dip and strike, dipmeter log, and RFT data to obtain a structural model for the reservoir. Cross-sectional, sector and, finally, full field reservoir simulation models were constructed and used by the team to generate a reservoir development and management plan. The simulation models were used to examine the relative merits of vertical, deviated and horizontal wells, well placement, offtake rates, gas compression requirements and pressure maintenance strategies. Due to the uncertainty in the size and shape of the field, development options were considered at each of three reserve levels: proven, probable and possible. The simulation results showed that well rates should be held to less than 8,000 stb/d and that horizontal wells, with a length of at least 700 m, generally out-performed vertical wells. Oil recovery ranged between 34 and 45% of OOIP. The cases offering the best recoveries included both water injection and horizontal wells.

    The arcuate, west-northwest-trending, mostly offshore New Ireland basin is 900 km long and about 160 km wide, and extends northeastward from Manus Island, New Hanover, and New Ireland. The basin formed in a forearc between a southerly Eocene to early Miocene volcanic arc, and a northerly outer-arc high bounding the Manus Trench. Its southern margin drops down to the back-arc Manus basin, which commenced spreading in the Pilocene. North of Manus Island, the New Ireland basin contains areas of deformed strata that have apparently been accreted to the Manus arc by south-dipping thrust faults. In places these strata are overlain by shallowly buried lava flows, which may represent attempted spreading. The sedimentary sequence in the eastern part of the basin is interpreted to contain thick Oligocene to early Miocene volcaniclastic sediments, overlain by 1000-2000 m of Miocene shelf carbonates, overlain by 2000 m of overburden. The presumed shelf carbonates could contain both source and reservoir rocks. The Lee line 401 revealed a flat, high-amplitude reflector or bright spot in an anticlinal core 1700 m beneath the seabed in water 2500 m deep off New Ireland, suggesting that hydrocarbons have been generated in New Ireland basin.

    The authors used the feathers of seven species of birds from New Guinea highland forests to examine concentrations of heavy metals and selenium. The authors tested the null hypotheses that there were no species, food type, or elevation differences in the concentrations of mercury, lead, cadmium, selenium, chromium, and manganese in the feathers of adults. All species had nondetectable levels of mercury. There were significant species differences in cadmium, lead, chromium, selenium, and manganese. Common smokey honeyeaters (Melipotes fumigatus, a fruit and flower feeder) had the lowest levels of all metals; blue-grey robin (Peneothello cyanus, mainly insectivorous) had the highest cadmium and manganese; and several species of birds of paradise had the highest lead levels. Lead levels were relatively high compared to those reported from feathers of other birds, attributable to the use of leaded gasoline.

  20. Geology and hydrocarbon potential of the Sepik-Ramu area, Ramu basin, Papua New Guinea

    Improvements in seismic processing have made new interpretations of the structural and depositional history of the northwestern portion of the Ramu basin possible. Support for a wrench tectonic model for this area is observed in the reprocessed seismic data. Strike-slip movement along major fault zones has allowed compressional forces to be translated laterally and resulted in only minor deformation occurring in the Sepik-Ramu area. The major tectonic event is thought to have occurred during late Miocene-early Pliocene, and not during the middle Miocene, as earlier hypothesized. Consequently, Miocene deposition is postulated to have occurred uninterrupted by periods of erosion. A thick Miocene section is preserved in this region and is postulated to contain slope, reef, and shelf carbonates of early to middle Miocene age. This interpretation has led to the identification of a reef trend over 7 mi wide and at least 42 mi long containing numerous pinnacle reefs. The pinnacle reefs are analogous to those found in the Salawati basin of Irian Jaya, Indonesia. The reefs are overlain by deep-water shales, a combination that provides potential reservoirs and seals necessary for the entrapment of hydrocarbons. The presence of oil and gas seeps document the existence of a source. These three factors justify hydrocarbon exploration in this area. The numerous potential drilling targets may lead to the discovery of significant quantities of hydrocarbons.

  1. Geochemical characteristics of oils from New Zealand, Papua New Guinea and Taiwan

    Oils from a number of convergent margin settings of the Pacific and Philippine plates have been characterized by geochemical techniques including gas chromatography-mass spectrometry and carbon isotopic analysis. The oils, collected from New Zealand, New Guinea, and Taiwan, are described in terms of their biomarker compositions, and these distributions are used to evaluate the nature of the source material responsible for the oils. For the most part these oils are of Tertiary age and the source materials were derived predominantly from higher plants. The authors describe the effects of a convergent margin on the relative maturity of the oils as reflected by their biomarker distributions. In other words, do any of the oils from these regions have anomalous maturity values that can be attributed to additional heating resulting from plate movement in the area. The results will also be compared with oils from similar source materials but not in convergent margin settings (for example, the Gippsland basin, Australia) to further evaluate the effects of the convergent margin setting on the biomarker distributions.

    New Guinea lies on the northern Australian plate boundary and has been a sensitive tectonic recorder of Cenozoic plate interactions between the Australian and Pacific plates. The specific plate interactions are documented by the evolution of the Northern New Guinea fault system and the basin it overprints, the Northern New Guinea basin. Consideration of plate kinematics suggests convergence became increasingly oblique during the Cenozoic. Hydrocarbon exploration strategies within the Northern New Guinea basin must address not only sedimentation, but also must deal with the basin's complex structural and tectonic evolution. A static tectonic classification will not adequately define the Northern New Guinea basin. It is better described as an evolving basin being overprinted by wrenching.

    Northwest to southeast regional scale flow in the Toro Sandstone parallels the Papuan Fold and Thrust Belt for a distance of 115 km, passing through Iagifu/Hedinia oil field along the way. This has had a profound effect on oil distribution in the Toro there, having swept the northwest side free of movable oil. A structurally controlled flow restriction causes a local, rapid drop in hydraulic potential, tilting local oil/water contacts up to six degrees and causing the three sandstone members of the Toro to locally behave as separate reservoirs, each with its own hydrocarbon/water contact. Reservoir simulations of Iagifu/Hedinia which include a flowing aquifer are able to match observed production history. Without a flowing aquifer, simulation predicts greater and earlier water production, and a greater pressure drop in the oil leg than has been observed. Reservoir modeling using a flowing aquifer has allowed downhole, structural targeting of later infill wells to be much closer to the OWC than would otherwise have been thought prudent, and has raised questions as to the potential effectiveness of a downdip water injection scheme. Production results from a small satellite field upstream of the main Iagifu/Hedinia field have shown a sudden increase in water production and reservoir pressure after a long period of pressure decline and no water production. This behavior appears to be due to an influx of higher hydraulic potential from a separate reservoir sand, the influx being brought about by pressure draw down during production and consequent breakdown of fault seal.

    The central and western Solomon Islands and the Bougainville regions are parts of a complex island-arc system that includes an intra-arc basin and remnants of both forearc and back-arc depositional wedges. These features formed in response to episodic Cenozoic tectonism along the convergent boundary between the Pacific and Australia-India plates. Presumed early Tertiary southwest-directed subduction of the Pacific plate and associated arc magmatism were curtailed by impingement of the leading edge of the Ontong Java Plateau. Aprons of back-arc and forearc sediment were derived from highstanding parts of the arc during the late Oligocene and early Miocene. Late Tertiary arc-polarity reversal and northeastward-directed subduction of the Woodlark spreading system caused a renewal of island-arc magmatism that completed the construction of the Central Solomons Trough as an enclosed intra-arc basin. Interpretations of multichannel profiles from 1982 and 1984 CCOP/SOPAC Tripartite Cruises of the research vessel R/V S.P. Lee indicate that the Central Solomons Trough is a composite intra-arc basin containing as much as 5.5 km of late Oligocene(.) and younger sedimentary rocks. As many as five lenticular seismic-stratigraphic units can be identified on the basis of unconformities and abrupt velocity changes. Late Miocene and younger folds and faults deform the northeast and southwest flanks of the basin. Profiles across the Kilinailau Trench show Ontong Java Plateau rocks covered by 2-4 km of trench sediment. The inner trench wall consists of folded, upfaulted, and rotated blocks of trench and forearc strata. The deep-water basin northwest of Bougainville is a southeastward extension of the New Ireland forearc basin, the southern margin of which is formed by a subsided part of the early Cenozoic arc. There, Oligocene(.) and younger basin strata, as much as 7 km thick, are deformed by pre-Pliocene faults and folds.

  5. Ramu basin, Papua New Guinea: A record of late Miocene terrane collision

    Cullen, A.B.

    1996-05-01

    The Ramu basin lies along a plate boundary where the Finisterre terrane is colliding with the Indo-Australian plate. Estimates for the age of initial collision range from early Miocene to middle Pliocene. Two unsuccessful wells (Keram 1 and Tsumba 1) drilled to basement and two-dimensional seismic data show that folded and faulted early to middle Miocene carbonates and clastics (the Wogamush sequence) are overlain by relatively undeformed Pliocene marine clastics (the Wewak sequence) along a regional unconformity. The pre-Pliocene section, which is at the crux of resolving the age of initial collision, has been correlated previously to the Finisterre terrane. Clastics within that section, derived from older terranes south of the basin, imply an early Miocene age for collision. I propose that Miocene sedimentary and volcanic rocks in the two wells are correlative with the Wogamush beds of the Maramuni arc. The Ramu basin can then be viewed as having a two-stage evolution. During the Miocene, the basin was part of the Maramuni arc, the polarity of which is unresolved. A collisional successor basin developed in the late Miocene as the Finisterre terrane (Adelbert block) collided with the arc. Thrust faults on the northeastern side of the basin, truncated by a regional unconformity, are interpreted to mark the suture of the Adelbert block. A northern earliest Pliocene sediment source for the basal Wewak sequence was probably the Finisterre terrane, but multiple source areas are inferred for the rest of that sequence. Middle Pliocene inversion of the basin`s northeastern flank, characterized by reverse faulting and forced folding, is attributed to plate boundary reorganization caused by rifting in the Bismarck Sea. The Ramu basin has numerous untested structures related to both collision and basin inversion. Gas-prone source rocks are present, but are largely immature. Reservoir and charge considerations place the Ramu basin in the very high risk sector for exploration.

    Cogenetic volatile-rich alkali basalts and gabbros, hawaiites, and mugearites occur in the late Miocene age epizonal Porgera intrusive complex, which is temporally and spatially associated with rich gold-silver mineralization. The least evolved rocks show enrichments in light rare earth elements ((La/Yb){sub cn} = 15-19) and other incompatible elements (e.g., Ba/La {approx} 8-10, La/Nb {approx} 0.6-0.7, Sr/Nd {approx} 25) characteristic of intraplate alkalic basalts and have isotopic compositions ({sup 87}Sr/{sup 86}Sr {approx} 0.7035, {epsilon}{sub Nd} {approx} +6, {sup 206}Pb/{sup 204}Pb {approx} 18.66, {sup 207}Pb/{sup 204}Pb {approx} 15.56, {sup 298}Pb/{sup 204}Pb {approx} 38.55) consistent with derivation from a time-averaged depleted mantle source. The Porgera intrusive complex was emplaced at 6 Ma in Jurassic-Cretaceous shelf-facies sedimentary rocks near the edge of the Australasian plate. Intrusion appears to have occurred in a back-arc environment during subduction of an oceanic microplate segment on two sides, beneath the continental margin and an island arc. We suggest that this unusual tectonic setting promoted partial melting of asthenospheric source materials that were perhaps modified by deep (>150 km) subduction processes to form alkalic magmas with intraplate character.

    The stable isotope composition of carbon can be used to provide information on the origin of carbon in soil organic matter. This study looks at the effect of decreasing temperature and atmospheric pressure (altitude) on the carbon-isotope composition of soil organic carbon from forests and grasslands in tropical regions. Investigators examine whether a predictable relationship exists between vegetation type, the 13C value of surface soil organic matter, and altitude. The results provide a framework within which to more accurately constrain the carbon-isotope composition of terrestrial carbon ppls and to interpret the observed variations in the isotopic composition of rivere particulate organic carbon. 31 refs., 5 figs., 1 tab.

    New Zealand experienced a marked increase in activity. Concession holdings went up 205% onshore to 62,429 km/sup 2/, and 31% offshore to 215,439 km/sup 2/. Seismic coverage more than doubled both onshore and offshore, to 1,075 and 15,321 line-km, respectively. Several new targets have been delineated offshore, and 2 drillships are scheduled to arrive in the country and start drilling during 1983. Onshore, the total depth drilled more than doubled to 18,993 m. Drilling was concentrated in the recently discovered McKee field, where 2 additional oil producers were completed, and on 3 other structures nearby, where 1 well tested gas and condensate. Production of gas and condensate from the Kapuni and Maui fields combined was 2,177.122 X 10/sup 6/ m/sup 3/ (up 69.3%) and 865,454 m/sup 3/ (up 57.3%), respectively. Expansion of the only refinery in New Zealand and the realization of large petrochemical projects using natural gas are well under way. These projects include an ammonia-urea plant, which was completed by year end, a methanol plant, and a methanol-to-synthetic petrol plant now under construction.

    Fracture prediction in a block cave of underground mine is very important to monitor the structure of the fracture that can be harmful to the mining activities. Many methods can be used to obtain such information, such as TDR (Time Domain Relectometry) and open hole. Both of them have limitations in range measurement. Passive seismic tomography is one of the subsurface imaging method. It has advantage in terms of measurements, cost, and rich of rock physical information. This passive seismic tomography studies using Fresnel zone to model the wavepath by using frequency parameter. Fresnel zone was developed by Nurhandoko in 2000. The result of this study is tomography of P and S wave velocity which can predict position of fracture. The study also attempted to use sum of the wavefronts to obtain position and time of seismic event occurence. Fresnel zone tomography and the summation wavefront can predict location of geological structure of mine area as well.

    Infill drilling based on integrated reservoir characterization and flow simulation is increasing recoverable reserves by 20 MMBO, in lagifu-Hedinia Field (IHF). Stratigraphically-zoned models are input to window and full-field flow simulations, and results of the flow simulations target deviated and horizontal wells. Logging and pressure surveys facilitate detailed reservoir management. Flooding surfaces are the dominant control on differential depletion within and between reservoirs. The primary reservoir is the basal Cretaceous Toro Sandstone. Within the IHF, Toro is a 100 m quartz sandstone composed of stacked, coarsening-upward parasequences within a wave-dominated deltaic complex. Flooding surfaces are used to form a hydraulic zonation. The zonation is refined using discontinuities in RIFT pressure gradients and logs from development wells. For flow simulation, models use 3D geostatistical techniques. First, variograms defining spatial correlation are developed. The variograms are used to construct 3D porosity and permeability models which reflect the stratigraphic facies models. Structure models are built using dipmeter, biostratigraphic, and surface data. Deviated wells often cross axial surfaces and geometry is predicted from dip domain and SCAT. Faults are identified using pressure transient data and dipmeter. The Toro reservoir is subnormally pressured and fluid contacts are hydrodynamically tilted. The hydrodynamic flow and tilted contacts are modeled by flow simulation and constrained by maps of the potentiometric surface.

    A series of oil and gas fields, including Iagifu-Hedinia, occur along the leading edge of the Papuan fold and thrust belt. Formed during Pliocene to Recent compression, they are structurally complex, and typically broken into multiple reservoir compartments. The presence of the karstic Darai Limestone at the surface over most of the fold belt prevents acquisition of useful seismic data. Reservoir mapping, and establishment of reservoir continuity, is therefore based soley on (1) surface geologic data, (2) drilling data; initially dipmeter and RFT pressure data, and subsequently well production histories, and (3) geochemical correlation of reservoir fluids. During appraisal of the Iagifu-Hedinia discovery, these complimentary data sets demonstrated that (1) a single hydrocarbon column existed above a flowing aquifer in the main block of Iagifu-Hedinia field, (2) a separate acuumulation existed in the Usano area. Geochemical data have suggested the presence of reservoir compartments where other data were missing or inconclusive. Subsequently-acquired production history data have confirmed the geochemically-based interpretations. Geochemical data suggest that oils at Iagifu-Hedinia have a common source. The slight differences in oil composition between reservoirs are likely due to multiple phases of expulsion from the same source rock and/or migration-fractionation.

    Soro West is a fault cut-off prospect located in the frontal portion of the Papuan Fold and Thrust Belt. Prospective Toro and Imburu sandstones are interpreted to be in the hanging wall of the Soro Thrust. Truncation against the thrust, both updip and through lateral ramps, provides the trapping mechanism. The Soro West Prospect was defined using geological, geochemical, remote sensing, and geophysical data. The definition and location of the trap is a primary risk and work was focused on this aspect. Surface geological data (lithology, strikes, and dips) topography and synthetic aperture radar imagery were incorporated into the evaluation. Statistical curvature analysis techniques helped define the shape of the structure and the locations of the lateral ramps. Strontium isotope analyses of Darai Limestone surface samples refined erosional levels using a locally-derived reference curve. Severe karst precludes the acquisition of coherent surface seismic data, so the primary geophysical tool used was magnetotellurics (MT). A detailed, pre-survey feasibility study defined expected responses from alternative structural models. The MT data demonstrated that the limestone at surface is underlain by thick conductive clastics and not another Darai Limestone sheet. The data also constrained the range of fault cut-off positions significantly. Multiple, three-dimensionally consistent, restorable alternative structural models were created using results from all analyses. These led to a positive assessment of the prospect and an exploratory test is to be drilled in 1996.

  20. Neogene evolution of the North New Guinea basin, Papua New Guinea: New constraints from seismic and subsidence analysis and implications for hydrocarbon exploration

    SciTech Connect (OSTI)

    Cullen, A.B.; Pigott, J.D. )

    1990-06-01

    The present-day North New Guinea basin is a Plio-Pleistocene successor basin that formed subsequent to accretion of the Finisterre volcanic arc to the Australian Plate. The Ramu, Sepik, and Piore infrabasins formed in a forearc setting relative to the continental Maramuni magmatic arc. The evolution of these infrabasins was strongly influenced by accretion of the composite Torricelli-Prince Alexander terrane to the Australian Plate. Regional reflection seismic data and tectonic subsidence-subsidence rate calculations for seven wells drilled in the North New Guinea basin reveal a complex history. The timing and magnitude of subsidence and changes in subsidence rates differ between each of the Miocene infrabasins. A diachronous middle to late Miocene unconformity generally truncates infrabasin sequences. The Nopan No. 1 in the Sepik basin, however, has a complete middle Miocene to Pleistocene sedimentary record. This well records late Miocene negative subsidence rates documenting that the Nopan anticline grew as erosion occurred elsewhere in the region. This circumstance suggests that the major, sequence-bounding unconformity results from regional uplift and deformation, rather than changes in global sea level. The Plio-Pleistocene evolution of the North New Guinea basin has two profound implications regarding hydrocarbon exploration. First, the late Pliocene structural inversion of parts of the basin hinders stratigraphic and facies correlation inferred from the present setting. The recognition of basin inversion is particularly important in the Piore basin for predicting the distribution of potential reservoir facies in the Miocene carbonates. Second, the subsidence data suggest that although potential source rocks may be thermally within the oil window, these rocks may not have had sufficient time to mature owing to their recent burial.

  7. Resource assessments in national planning - Pupua New Guinea case studies

    SciTech Connect (OSTI)

    Pintz, W.S.; Clark, A.L.

    1984-01-01

    The nation of Papua New Guinea, encompassing 462,000 square miles of land area and a population of approximately 3 million individuals, occupies the eastern half of the island of New Guinea and includes the Bismarck Archipelago and Bougainville Island. The diversity and complexity of Papua New Guinea's geology, coupled with the large number of known mineral occurrences of various deposit types, leads to the inescapable conclusion that the resource potential of Papua New Guinea is very large. In recognition of this potential, a resource assessment of Papua New Guinea was undertaken for the stated purpose of integrating the results of such an assessment into the nation's planning activities.
