Diagenesis and fracture development in the Bakken Formation, Williston Basin: Implications for reservoir quality in the middle member
The middle member of the Bakken Formation is an attractive petroleum exploration target in the deeper part of the Williston Basin because it is favorably positioned with respect to source and seal units. Progressive rates of burial and minor uplift and erosion of this member led to a stable thermal regime and, consequently, minor variations in diagenesis across much of the basin. The simple diagen

Diagenesis and reservoir quality of the Upper Mississippian Aux Vases Sandstone, Illinois Basin
Conventional reservoir quality data for more than 300 wells provided by the Illinois and Indiana state geological surveys were analyzed to determine the factors governing porosity and permeability in the Upper Mississippian Aux Vases Sandstone, an important hydrocarbon-producing unit in the Illinois Basin. In addition, approximately 150 samples of the Aux Vases Sandstone were collected for mineral

Geologic controls on the formation of lakes in north-central Florida
Fluid exchange between surficial waters and groundwater, as well as the processes that control this exchange, are of critical concern to water management districts and planners. Digital high-resolution seismic systems were used to collect geophysical data from 30 lakes of north-central Florida. Although using seismic profile data in the past has been less than successful, the use of digital techno

Reservoir quality and diagenetic evolution of Upper Mississippian rocks in the Illinois Basin; influence of a regional hydrothermal fluid-flow event during late diagenesis
Conventional reservoir quality data for more than 300 wells provided by the Illinois and Indiana State Geological Surveys were analyzed to determine the factors governing porosity and permeability in the Upper Mississippian Bethel Sandstone and Cypress Sandstone, two of the principal producing units in the Illinois Basin. In addition, approximately 150 samples of the Bethel Sandstone-Cypress Sands

Regional diagenetic patterns in the St. Peter Sandstone; implications for brine migration in the Illinois Basin
Diagenetic minerals and alteration patterns in the
Ordovician St. Peter Sandstone, Illinois Basin, record varied
hydrologic and chemical conditions during the basin?s long
and complex geologic history. Major diagenetic events modifying
the St. Peter Sandstone include (1) mechanical compaction,
(2) early K-feldspar overgrowth and dolospar
precipitation, (3) burial quartz, dolospar, anhydrite,

Diagenesis of hydrocarbon-bearing rocks in the Middle Ordovician Simpson Group, southeastern Anadarko Basin, Oklahoma
Quartzarenites and subarkoses in the Middle Ordovician Simpson Group in the Gulf Costello No. 1 and Sunray-DX Parker No. 1 Mazur wells, southeastern Anadarko basin, have undergone a complex diagenetic and petroleum-migration history. During early burial, petroleum migrated locally through sandstones; patches of bitumen in calcite and bitumen-lined quartz overgrowths containing oil-bearing inclusio
