Subsurface Stratigraphy And Characterization Of Mississippian (Osagean To Meramecian) Carbonate Reservoirs Of The Northern Anadarko Shelf, North-Central Oklahoma, Brett Robert Wittman
Subsurface Stratigraphy And Characterization Of Mississippian (Osagean To Meramecian) Carbonate Reservoirs Of The Northern Anadarko Shelf, North-Central Oklahoma, Brett Robert Wittman
Graduate Theses and Dissertations
Mississippian carbonate strata of the midcontinent contain prolific oil and gas reservoirs. Production from these carbonates has been primarily from two reservoir types, the Mississippi "chat" and recently denser chert-rich mudstone intervals. The"chat" interval is a high porosity chert residuum associated with the both the Osagean and basal Pennsylvanian unconformity. The distribution of the "chat" reservoir is discontinuous and heterogeneous. Recent horizontal drilling successes have reinvigorated academic and industry interest in the Lower Mississippian. Much of the activity is now targeting lower porosity, cherty, mudstone intervals of the Reeds Spring and Cowley Formations, which were previously considered to be non-economic. …
Depositional Setting And Sequence Stratigraphic Analysis Of The Lower Permian Lower Hueco Formation On The Western Margin Of The Orogrande Basin, South Central New Mexico, Jonathon Eric Stautberg
Depositional Setting And Sequence Stratigraphic Analysis Of The Lower Permian Lower Hueco Formation On The Western Margin Of The Orogrande Basin, South Central New Mexico, Jonathon Eric Stautberg
Open Access Theses & Dissertations
On the western margin of the Orogrande Basin in south-central New Mexico, eight outcrop datasets, in the form of measured stratigraphic sections from the lower interval of the Lower Permian Lower Hueco Formation were analyzed in regard to depositional facies distribution and sequence stratigraphy. Based on petrographic analysis of 247 samples and associated field relationships, 11 depositional facies are recognized: 1) quartz sandstone, 2) quartz siltstone and shale, 3) fenestral dolomudstone, 4) microbial intraclast packstone, 5) dolomudstone, 6) green-algal packstone to grainstone, 7) ostracode foram wackestone, 8) oolitic packstone, 9) fossiliferous packstone and grainstone, 10) fusulinid packstone and grainstone, 11) …
Messinian Forced Regressions In The Adana Basin: A Near-Coincidence Of Tectonic And Eustatic Forcing, Ayhan Ilgar, Wojciech Nemec, Aynur Hakyemez, Erhan Karakuş
Messinian Forced Regressions In The Adana Basin: A Near-Coincidence Of Tectonic And Eustatic Forcing, Ayhan Ilgar, Wojciech Nemec, Aynur Hakyemez, Erhan Karakuş
Turkish Journal of Earth Sciences
This sedimentological and sequence-stratigraphic study focuses on the late Miocene deposits in one of the largest peri-Mediterranean basins of southern Turkey, the Adana Basin, which formed as a Tauride foreland depression accumulating molasse deposits. The Tortonian-Messinian shallow-marine Handere Formation, previously interpreted as a regressive succession, appears to have recorded several relative sea-level changes. The formation base recorded a forced regression attributed to the end-Serravalian (Tor-1) eustatic fall in sea level. The lower to middle part of the formation is transgressive, culminating in offshore mudstones. The upper part is regressive and its 3 isolated conglomeratic members represent sharp-based Gilbert-type deltas with …

On The Long Duration Of Till Sheet Construction : A Reassessment Of How Quaternary Grounding Line Translations Relate To Near-Surface Seismic-Stratigraphy Of Eastern Ross Sea, Antarctica, Sydney Grace Bowles
LSU Master's Theses
Previously acquired seismic surveys provide strong evidence that the post-Last Glacial Maximum (LGM) retreat of the West Antarctic Ice Sheet (WAIS) deposited a back-stepping succession of seismically-resolved grounding zone wedges (GZWs) in eastern Ross Sea. However, the chronology of WAIS retreat is debated. The conventional view is that three GZWs (Red, Brown, and Gray Units) were deposited since the LGM. An alternative view, based on recent radiocarbon dates, is that the youngest GZW (the Gray Unit) was deposited during the LGM. If correct, then the older GZWs (Red and Brown Units) were deposited prior to LGM. A recent study (Bart …

Lithological And Sequence Stratigraphic Examination Of The Madison Group Marker Beds, Eastern Williston Basin Margin, North Dakota, Troy Jd. Skitt
Theses and Dissertations
The Frobisher-Alida interval consists of eight log-defined subintervals or “beds” within the Mississippian upper Mission Canyon and lower Charles Formations of the Madison Group in the Williston Basin. The subintervals are composed of predominantly evaporite and carbonate lithologies, and include in descending order: 1) Midale, 2) Rival, 3) Bluell, 4) Sherwood, 5) Mohall, 6) Glenburn, 7) Wayne, and 8) Landa. The top of the lower six subintervals are separated by thin but areal extensive log-defined markers of contrasting lithologies and include in descending order: 1) State A, 2) Sherwood Argillaceous Marker (S.A.M.), 3) K-1, 4) K-2, 5) K-3, and 6) …
