Project Profile
Location: Pickaway County, Ohio
Start-up Year: August 2015
The Knox unconformity is highly prospective for oil in south central Ohio and the Marksmen’s lands have been geologically mapped by analysing the well logs and 2D seismic data from previously drilled vertical wells that penetrated the Knox unconformity in the immediate area. There are several wells drilled in the vicinity that have produced more than 50,000 barrels of oil from the Knox unconformity utilizing 2D seismic surveys, with more than 1 million barrels of oil produced from 3 fields. 3D Seismic has been proven as a viable and cost effective exploration tool to accurately image hydrocarbon traps associated with the Knox unconformity in other parts of Ohio.
The Delong-Davis Unit #1 well was spudded on July 20, 2015 and reached its total depth on July 26, 2015 targeting a large Cambrian Knox remnant that was drilled based on the interpretation of new 3D seismic and encountered significant oil and gas shows in the top of the Cambrian Knox formation where open hole logs recorded porosities of greater than 20% over a 6 foot interval. Oil did circulate to surface. The well is currently being completed for commercial production and is expected to have a pump-jack and bottom-hole equipment in place in a week with the tanks and other surface equipment to follow shortly.
