Title: Failure of cap-rock seals as determined from mechanical stratigraphy, stress history, and tensile-failure analysis of exhumed analogs

Abstract

In this study, the sedimentologic and tectonic histories of clastic cap rocks and their inherent mechanical properties control the nature of permeable fractures within them. The migration of fluid through mm- to cm-scale fracture networks can result in focused fluid flow allowing hydrocarbon production from unconventional reservoirs or compromising the seal integrity of fluid traps. To understand the nature and distribution of subsurface fluid-flow pathways through fracture networks in cap-rock seals we examine four exhumed Paleozoic and Mesozoic seal analogs in Utah. We combine these outcrop analyses with subsidence analysis, paleoloading histories, and rock-strength testing data in modified Mohr–Coulomb–Griffith analyses to evaluate the effects of differential stress and rock type on fracture mode.

Quantification of tertiary exhumation in the United Kingdom southern North Sea using sonic velocity data

Journal Article Hillis, R R - AAPG Bulletin

Sonic velocities from the Upper and Middle Chalk (Upper Cretaceous), the Bunter Sandstone and the Bunter Shale (both Lower Triassic) were used to independently quantify apparent exhumation (height above maximum burial depth) in the United Kingdom (UK) southern North Sea. Apparent exhumation is the displacement, on the depth axis, of a given velocity/depth trend from the normal (unaffected by exhumation) trend. Apparent exhumation results derived from the Upper and Middle Chalk, the Bunter Sandstone, and the Bunter Shale are statistically similar. The consistency of results from carbonate and clastic units suggests that, at a formational and regional scale, over-compaction (i.e.,more »« less
Paleozoic cratonal/miogeoclinal stratigraphy in the western Mojave Desert

Conference Martin, M W ; Walker, J D - AAPG Bulletin (American Association of Petroleum Geologists); (United States)

Detailed mapping of metasedimentary rocks by many workers in the western Mojave Desert, California, has revealed Paleozoic lithologies of cratonal/miogeoclinal affinity. These exposures are metamorphosed, highly strained, and dismembered, and sit as roof pendants to Mesozoic and Tertiary intrusive rocks. In most outcrops no diagnosis fossils are preserved. Age correlation of these units is based, therefore, solely on similarities to lithologic packages outside the region. Despite the complex tectonic history this area has suffered since the late Paleozoic paleogeographic elements trend southwest into the region from where they are last clearly defined near the California-Nevada border.

Major Oil Plays In Utah And Vicinity

Technical Report Chidsey, Thomas

Utah oil fields have produced over 1.33 billion barrels (211 million m{sup 3}) of oil and hold 256 million barrels (40.7 million m{sup 3}) of proved reserves. The 13.7 million barrels (2.2 million m3) of production in 2002 was the lowest level in over 40 years and continued the steady decline that began in the mid-1980s. However, in late 2005 oil production increased, due, in part, to the discovery of Covenant field in the central Utah Navajo Sandstone thrust belt ('Hingeline') play, and to increased development drilling in the central Uinta Basin, reversing the decline that began in the mid-1980s.more »« less

Crustal Fluid Evolution and Changes in Deformation Conditions during Regional Syn- to Post-Orogenic Exhumation: Southeastern Piedmont, Southern Appalachians

Journal Article Evans, M A - Geological Society of America Bulletin

Fluid inclusion microthermometric data from veins in the southeastern Piedmont province record the changes in fluid composition and deformation conditions during regional exhumation and cooling related to Late Paleozoic syn- to post-orogenic processes and early Mesozoic rifting. In general, the composition of post-metamorphic fluids that were trapped late during the Alleghanian orogeny and during post-orogenic exhumation are remarkably consistent across the southeastern Piedmont, indicating regional fracture connectivity. The first fluids were trapped in veins that formed during the last phases of the Alleghanian. These syn-deformational fluids are CO2-saturated low salinity brines (salinities of 2.6 to 5.7 wt. percent NaCl equivalent)more »« less

Geology and tectonic history of the Whitehorse trough west of Atlin, British Columbia

Thesis/Dissertation Bultman, T R

The Mesozoic Whitehorse trough extends southeast from the south-central Yukon into northern British Columbia. In the study area, the trough strata are separated from the oceanic Upper Paleozoic Atlin Terrane to the Northeast by the steeply northeast-dipping Nahlin fault, and from the Upper Paleozoic and older amphibolite to greenschist facies metamorphic rocks and plutons of the Coast plutonic complex to the southwest by the subvertical Llewellyn fault system. The trough is a synclinorium with basal Upper Triassic strata exposed only along the margins; they are mainly flows and associated volcaniclastic rocks capped by fossiliferous limestone on the south-west and pyroclasticmore »« less
