Geology, Hydrocarbon Production, and Horizontal Drilling in the Upper Devonian Berea Sandstone, Eastern Kentucky: References and Data Resources

Compiled by David Harris, Kentucky Geological Survey, June 2013.

The Berea Sandstone has been a major producer of natural gas in eastern Kentucky for decades, but recent horizontal drilling activity in northeastern Kentucky has generated new interest in this reservoir interval. In this area, the Berea produces oil in addition to gas due to the lower thermal maturity of the adjacent source rocks. Horizontal drilling combined with hydraulic fracturing technology have been successful in enhancing oil production rates compared to older vertical wells. The references and data sources linked below are provided to assist oil and gas operators in understanding the geology and hydrocarbon potential of the Upper Devonian Berea Sandstone, with particular emphasis on the emerging horizontal oil play.

(These links will return lists of permitted horizontal wells in the specified counties with significant Berea activity. Some of these wells have scanned documents and logs available for viewing after installation of the DjVu browser plug-in. Note that horizontal wells included in the results may include target formations other than the Berea. The selected wells can be mapped by clicking the "Map Results on Geologic Map Service" button.)
