Surprises from the Devonian Foreknobs Formation of Eastern West Virginia

Unusual microfossils recently recovered from the Upper Devonian Foreknobs Formation (Greenland Gap Group) of eastern West Virginia suggest that the paleoenvironmental model for the unit may need revision or refinement. Rock samples from lowermost Foreknobs containing a combination of sedimentary material suggests paleoenvironments ranging from fluvial to brackish water lagoon to back-reef marine to normal marine shelf. While the assemblage probably represents a storm deposit, it indicates sedimentary "sampling" of Foreknobs depositional environments that are not preserved or not yet exposed in this part of the Appalachians.

The Shifting Landscape of Marcellus Shale Development in West Virginia

West Virginia, known historically as a coal producing state, has recently experienced a dramatic increase in natural gas production from the Marcellus Shale. Since 2005, over 2100 Marcellus wells have been drilled in the state. A number of vertical wells penetrated and produced from the Marcellus Shale before 2005, but use of the technical combination of horizontal drilling and hydraulic fracturing of wells created a rapid escalation of shale gas drilling in the Appalachian basin. Projections for future production continue to increase. The West Virginia Geological and Economic Survey continuously updates a database for all oil and gas activity in West Virginia while conducting geological research. Current research includes the examination of the geological controls on the Marcellus Shale as well as a volumetric resource assessment of Marcellus potential in the State.

West Virginia Earthquakes: Crustal Adjustments along The Rome Trough or Something Else?

Ronald R. McDowell, J. Eric Lewis, and Philip A. Dinterman

Since 1966, there have been 33 instrumentally recorded earthquakes recognized in western West Virginia within or adjacent to the structural feature known as the Rome Trough. This structure is a fault-bounded graben involving basement rocks thought to be related to failed rifting of the North American plate during the Precambrian. Interestingly, 7 of the 11 "shallow" earthquakes occurred in Braxton County, WV in a single year (2010). We speculate that the "deeper" earthquakes are associated with isolated, recurrent fault movements in response to ancient crustal stresses within and along the margins of the Rome Trough. The "shallow" earthquakes recorded in Braxton County may reflect slip related to injection activity from a saltwater disposal well that injects at a depth of 1.7 km in close proximity to a recently discovered normal fault.

Assessing Suitability of Depleted Fields for Enhanced Oil Recovery in West Virginia

Oil production has been a part of West Virginia's economy since 1860. Cumulative statewide oil production rates peaked at 16 million barrels in 1900 and began a steady decline that led to eventual abandonment of many early fields. Of the remaining active fields, several continue to be economically viable today due to secondary recovery water floods and are the focus of examination for potential tertiary recovery via CO2 floods. As part of an effort led by the Midwestern Regional Carbon Sequestration Partnership (MRCSP) to identify potential carbon capture, utilization, and storage (CCUS) opportunities, the West Virginia Geological and Economic Survey is examining reservoir parameters in an attempt to establish a suitability ranking system for WV oil fields. Key characteristics were derived from existing sources and several fields were identified as potential targets for more detailed characterization. Many of West Virginia's coal-fired power plants are situated within 20 miles of EOR suitable fields and would be readily-available sources of CO2 if the cost of retrofitting the plants became economically viable.
