Faunal Distribution And Relative Abundance In A Silurian (Wenlock) Pinnacle Reef Complex - Ray Reef, Macomb County, Michigan, Jennifer L. Trout

Masters Theses

Niagaran (Silurian) reefs are important sources of hydrocarbons in the Michigan Basin. In addition, some of these reservoirs have been used for gas storage and may be potential CO2 sequestration sites.

Despite extensive research on Niagaran reefs, most studies concerning faunal abundance and distribution have been qualitative studies conducted by paleontologists with an emphasis on taxonomy, paleoecology, and evolution.

This study is the first quantitative study of relative abundance and general distribution of fauna throughout a single Wenlock reef located in the southern trend of the Michigan Basin. This study will build on previous work done by WMU students and …

Stratigraphic Framework For Deposits Of The Saginaw Lobe, Barry And Calhoun Counties, Michigan, Usa, Stephanie K. Ewald

Masters Theses

Between 2006 and 2012, twelve rotasonic borings were drilled in Barry and Calhoun Counties, south central Michigan, as part of several Great Lakes Geological Mapping Coalition projects. Natural gamma ray logs were collected at every location and a detailed description and textural analysis was completed for seven of these cores. Five of the seven analyzed cores reached bedrock. Six of the seven borings were drilled north of the Kalamazoo Moraine of the Saginaw Lobe, which was constructed during retreat of the lobe after the Late Glacial Maximum. Five borings, drilled in tunnel valleys, indicate an increase in depth of tunnel …

Characterizing The Internal Architecture Of Upper Bone Spring Limestone Turbidites And Mass-Transport Deposits (Mtds) Utilizing High-Resolution Image Log Technology, Jason J. Asmus

Masters Theses

Characterization of reservoir scale (less than 1 meter thick) turbidites and mass-transport deposits (MTDs) using conventional subsurface data is complex, due to millimeter-centimeter scale architectural heterogeneity exhibited by these deposits.

Limited studies of the Bone Spring carbonate turbidites and MTDs within the Delaware Basin subsurface emphasized the use of conventional wire-line log and seismic data to evaluate reservoir potential of such strata. As a result, limited resolution offered by these data sets do not allow for accurate characterization of reservoir, and sub-reservoir scale, architectural and compositional variations.

The present investigation integrates high-resolution (centimeter scale) electrical borehole image logs with conventional …

Reservoir Characterization And Enhanced Oil Recovery Potential In Middle Devonian Dundee Limestone Reservoirs, Michigan Basin, Usa, Abrahim Abduslam

Masters Theses

Middle Devonian Rogers City and subjacent Dundee Limestone formations have combined oil production in excess of 375 MMBO. In general, hydrocarbon production occurs in two distinct reservoir types: 1) bottom water drive, fractured dolomite reservoirs in the Rogers City and 2) gas expansion drive, depositional facies controlled limestone reservoirs of the Dundee.

The main objective of this study is to evaluate the enhanced oil recovery (EOR) potential in Dundee Limestone reservoirs on the basis of detailed geological reservoir characterization in several fields in the Michigan Basin. Seven main depositional facies were identified from core studies in six fields. Three of …

Geophysical And Remote Sensing Applications For A Better Understanding Of The Structural Controls On Groundwater Flow In The Lucerne Valley, California, Dale R. Dailey

Masters Theses

An integrated study was conducted in the Mojave Basin to investigate the potential role of faults and basement uplifts for groundwater flow in the Mojave Desert. Observations made include: 1) Very Low Frequency (VLF) measurements across mapped (using LIDAR and Geoeye-1 imagery) fault traces showed significant radio field dip angles indicative of presence of shallow sub-vertical, sheet-like conductors; many of the VLF tilt peaks coincided with changes in the magnetic profiles; 2) Vertical Electric Soundings indicate shallow basement west of, and parallel to, the Helendale Fault and deep saturated zones east of the fault/basement outcrop (F/B); and 3) isotopic analyses …

A Localized Investigation Of High Resolution Groundwater Flow Properties Of The Saginaw Aquifer Mason, Michigan, Amanda Hayden

Masters Theses

High resolution groundwater models can aid in better management of groundwater resources through more accurate characterization and quantification of aquifer systems. Detailed assessments of flow properties in the context of sedimentary facies can provide high quality data input for more accurate groundwater models.

The Pennsylvanian Grand River and Saginaw bedrock formations comprise the Saginaw Aquifer located in the Lansing, Michigan Tri-County region. The Saginaw Aquifer consists of a predominately shale and sandstone successions. These sandstone facies range up to 40 meters thick, and supply a significant amount water resources to the Lansing Tri-County area. Data used in this study was …

Integrating Depositional Facies And Stratigraphy In Characterizing Hydrothermal Dolomite Reservoirs: Trenton Group Of The Albion-Scipio Trend, Michigan, Marcel R. Robinson

Masters Theses

Reservoir characterization of carbonate rocks requires understanding the role of depositional and diagenetic parameters in reservoir distribution. This is especially true for the diagenetically-altered and structurally-influenced Trenton-Black River reservoirs of the Michigan Basin. Evaluating the depositional evolution and reservoir characteristics of component depositional facies through modeling and stratigraphic reconstruction would aid in exploration and characterization through providing a prediction tool for reservoir distribution, both within and outside of the Michigan Basin.

Results indicate that reservoir development is controlled by primary rock fabric related to depositional facies. Depositional and stratigraphic reconstructions show facies distribution trends occur consistently and therefore predictably away …

Evaluating The Effects Of Lithofacies And Thin Shales On The Lateral Distribution Of Hydrothermal Dolomite Reservoirs In The Michigan Basin, Peter J. Feutz

Masters Theses

The southern Michigan Basin contains numerous hydrothermal dolomite hydrocarbon fields, including the giant Albion-Scipio Field. The fields typically encompass narrow zones of faulting and fracturing which have been altered from a tight host limestone into a more porous and permeable dolomite by upward-moving hydrothermal fluids. Alternating layers of dolomite that spread laterally away from the main vertical fault conduits imply that structure alone may not define the resulting reservoir architectures within the region. A detailed analysis of primary depositional facies and thin shale seams suggests that secondary stratigraphic controls play a significant role in the development of reservoir rock within …
