Abstract

Structures produced over the top or along the margins of Silurian Pinnacle reefs have proven to be the source of significant oil production in the eastern Illinois basin. The authors have been able to refine gravity methods that can assist in the exploration of such reef targets. A gravity/density model was developed by combining the 1980 work of Dana at the Wilfred pool (Sullivan County, Indiana) with other lithologic and log data in southwestern Indiana. This model includes the density differences between the reef facies and surrounding lithologies as well as density variations that are the result of compaction of the sedimentary sequence above the reef. The density models suggest that positive gravity anomalies with amplitude between 1.5 to 2.5 mgals might occur over the reefs.

Silurian pinnacle reef distribution in Illinois: model for hydrocarbon exploration

Conference Whitaker, S - AAPG (Am. Assoc. Pet. Geol.) Bull.; (United States)

Approximately 92 million bbl of oil have been produced in Illinois from buried Silurian pinnacle reefs and from younger strata draped over these reefs. Better understanding of Silurian reef distribution and the use of appropriate exploration methods should lead to the discovery of new reef-associated hydrocarbon reserves. Evidence presented in this study suggest that Silurian pinnacle reef development was not limited to hinge-line trend around a subsiding basin center. Instead, isolated reefs grew through most of Illinois along a broad ramp dipping gently southeastward under a relatively shallow sea that opened to the south during the Silurian.

Analysis of gravity anomaly over coral-reef oil field: Wilfred Pool, Sullivan County, Indiana

Journal Article Dana, S - Am. Assoc. Pet. Geol. Bull.; (United States)

To compare the measured and theoretical gravity anomaly of a typical coral-reef oil field, data were collected from the wilfred Pool, Sullivan County, Indiana. Densities of available core samples from the field were determined and the anomaly was calculated, taking into account the lateral and vertical variation of density and the geologic structure known from core studies and drilling-log records of lithologic types penetrated by the wells. Comparison of the theoretical and actual anomalies indicated a rough correspondence except for several sharp negative anomalies on the flanks of the measured gravity anomaly. Further studies indicated that the negative anomalies aremore »« less
Silurian reefs in southwestern Indiana and their relation to petroleum accumulation

Journal Article Becker, L; Keller, S - Occas. Pap., Indiana Geol. Surv.; (United States)

Additional petroleum exploration is merited in a large area of SW. Indiana where petroleum accumulations probably will be found in association with Silurian pinnacle reefs. The strata in which accumulations may be found are Mississippian--the Ste. Genevieve Limstone, the Aux Vases Formation, and the Salem Limestone--and the Middle Devonian carbonate section. Not to be overlooked are the Silurian reef bodies themselves. The most promising area for future exploration is a large part of the particularly thick Silurian section that extends from Spencer County northwestward through Dubois, Daviess, Greene, and Sullivan counties. But reefal complexes may be found basinward from themore »« less
Seismic expression of Marts field (Silurian reef) in Sullivan County, Indiana

Conference Renick, Jr, H; Rene, R; Hester, N; ... - AAPG Bulletin (American Association of Petroleum Geologists); (USA)

The Marts field of Sullivan County, Indiana, is associated with a Silurian reef that is part of the Terre Haute bank on the eastern flank of the Illinois basin. Gas production has come from Pennsylvanian sandstones at Marts field, and oil is presently being produced from limestones of the Devonian Muscatatuck Group. Hydrocarbons were trapped in the Devonian limestones because of structural drape over the reef. A 2.8-km (1.8-mi) north-south 24-CDP reflection seismic profile across the Marts field was obtained by using a hydraulic-assisted weight drop with a source array interval of 16.7 m (55 ft). The data were digitallymore »« less
Gravity survey of marine field: Case study for Silurian reef exploration

Conference Heigold, P; Whitaker, S - AAPG Bulletin (American Association of Petroleum Geologists); (USA)

A gravity survey conducted over and around Marine field in southwestern Illinois has been used as an example to show how measurement of the local gravity field can aid in the search for Silurian reefs in the Illinois basin. Acquisition parameters for gravity surveys over Silurian reefs should be calculated beforehand from simple models of the reef based on estimates of density contrasts, depths, and size. Residual and derivative mapping techniques generally enhance gravity anomalies and enable more accurate portrayals of the structural relief on buried reefs. The second vertical derivative map of the residual Bouguer gravity anomaly surface atmore »« less
