Investigation Of Carbon Sequestration Potential Of The Middle Devonian Sylvania Sandstone, Michigan Basin, U.S.A, Farsheed Rock

Masters Theses

The Sylvania Sandstone is an important brine reservoir in Michigan. This study investigates the geological carbon sequestration potential of this reservoir through integrated reservoir characterization using cores, thin sections, core analysis data and modern wireline log data.

Core-to-wireline-log correlation can be used to subdivide the Sylvania Sandstone into conventional reservoir sandstone, and mixed dolostone, low permeability reservoir tripolitic chert and low permeability limestone lithologies. Isolith maps and cross sections indicate that the reservoir sandstone lithology dominates in southeast Michigan and is transitional to a mixture of sandstone, dolostone, tripolitic chert and limestone lithologies toward the northwest that in turn are …

Geological Controls On Reservoir Quality And Geologic Carbon Sequestration Potential In The Upper Cambrian Mount Simon Sandstone, Kyle Patterson

Masters Theses

The Upper (?) Cambrian Mount Simon Sandstone is an important deep saline geological carbon sequestration (GCS) target throughout the Midwest, USA. The distribution of sedimentary facies, primary mineralogy, and diagenetic alterations and the relationship to wireline log response and reservoir quality throughout the Michigan basin are not well known. This study uses rock core, thin section point counts, x-ray diffraction, inferred spectroscopy, conventional core plug porosity and permeability and pressure fall-off test data to constrain wireline log interpretations of regional geology and reservoir quality.

Prior to the permitting of a CO₂ sequestration project, documentation of a robust transient injection …

High Resolution Depositional Analysis Of The Black River Group (Ordovician), Michigan Basin, Jennifer Elaine Schulz

Masters Theses

The Ordovician Trenton and Black River carbonates of the Michigan Basin are significant hydrocarbon reservoirs that are characterized by hydrothermal dolomitization. Production has exceeded 132 million barrels of oil with forty new discoveries made in the past three years. The giant Albion-Scipio Trend is often used as a model for other prolific hydrothermal dolomite reservoirs around the world with current models focused on the structural control of reservoir quality dolomite.

Previous studies of the Black River Group have not delimited a well-constrained depositional model. This study integrates high-resolution core interpretations, whole core analysis, and thin section evaluation to determine how …

Prediction Of Petrophysical Properties Of Trenton-Black River (Ordovician) Reservoirs By Comparing Pore Architecture And Permeability To Sonic Velocity, John E. Thornton

Masters Theses

Reservoir characterization of carbonate rocks is complicated by heterogeneous pore architecture related to primary depositional facies and subsequent diagenesis; this is especially true in diagenetically-altered and structurually-influenced Trenton-Black River reservoirs of the Michigan Basin. Accurate and reliable prediction of reservoir properties within hydrothermal dolomite reservoirs through the use of acoustic properties would aid exploration and characterization both within and outside of the Michigan Basin.

Results indicate that measures of pore architecture when integrated with measures of physical properties into multiple variable linear regression can accurately predict permeability of core plugs. However, due to the highly-heterogeneous distribution of pore architecture and …

Investigating The Influence Of Organic Acids On Uraninite Solubility And Uranyl Sorption Onto Kaolinite, Michelle L. Barger

Dissertations

Within anoxic near surface aqueous settings where U0_2(S) may be released an opportunity to encounter and complex with organic acids may occur. Reactions between U0_2(S) and ligands may promote the solubility and mobility of uranium. Organic ligands investigated in the dissolution work include citric acid, NTA and EDTA. Exposure to the ligands had little effect on U0_2(S) solubility. The log activity of U0_2(S) hydrolysis under reduced conditions was -6.56. Under all measured conditions of ligand concentration, the data consistently show an increase in uranium concentration to a median log U activity of -4.89. The observed solubility …
