Analysis Of Depositional Facies And Geological Controls On Reservoir Quality In Lower-Middle Devonian Sylvania Sandstone, Midland County, Michigan, Katherine A. Pollard

Masters Theses

The early-Middle Devonian Sylvania “Sandstone” is considered a target for potential CO₂ geosequestration. In order to develop geostatic models for CO₂ injection simulations, controls on reservoir properties must be addressed. The three objectives of this study involve: 1) develop an overview of depositional lithofacies and their vertical stacking relationships, 2) determine fluid sources and controls of diagenesis (dolomitization and silicification), and 3) examine geological controls on the distribution and character of reservoir facies.

The grossly transgressive Sylvania-Bois Blanc interval is a complex lithologic assemblage. Sylvania “Sandstone” strata transition from high energy, subtidal to lower-intertidal mixed carbonate-siliciclastic facies to …

Late Mississippian (Chesterian) Through Early Pennsylvanian (Atokan) Strata, Michigan Basin, U.S.A., Shannon M. Towne

Masters Theses

Over 2,000 linear feet of core material was analyzed to evaluate the stratigraphy and basin evolution of Carboniferous strata in the Michigan basin. Rock units were evaluated on the basis of lithofacies type, contact relationships, and existing regional geologic interpretations. The recovery of three distinct pollen and spore assemblages from core confirms the timing of deposition during the Late Mississippian Chesterian and Early-Middle Pennsylvanian Morrowan and Atokan regional stages within the Michigan basin.

The deposition of a marine carbonate succession with significant interstratified quartz sandstone occurred during the Chesterian regional stage. The Bayport interval (Bayport Limestone) is composed of seven …

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) …

The Contribution Of Small Anthropogenic Particulates (Sap) To The Sediment Load Of A Major Ephemeral Fluvial System, Santa Ana River (Sar), Southern California, Junjie Shen

Theses Digitization Project

This research was undertaken to explore the distribution of small anthropogenic particulates (SAP) in the Santa Ana River (SAR), and to determine the contribution of SAP to the sediment load of the SAR. SAP have never been documented before in the fluvial systems, especially in Southern California. This project will effectively establish a baseline for future changes in SAP for environmental monitoring and regulations.
