From a press release this week:

CALGARY, ALBERTA, June 21, 2016 -- Marksmen Energy Inc. ("Marksmen" or the "Company") is pleased to announce that Marksmen, as operator, and its joint venture partner Houghton Investments LLC., drilled a discovery well at its Pickaway County, Ohio, Davis-Holbrook #1 well location on a large Cambrian Knox target outlined by Marksmen's 3D Seismic programs.

The discovery well was spudded on June 14, 2016. The well which had a projected total depth of 2,480 feet produced free flowing oil to surface from a depth of 2,357 vertical feet from the Cambrian Knox formation. The Davis-Holbrook #1 well intersected the Cambrian Knox formation 40 feet stratigraphically higher than the Company's Strittmatter 1 well, which is located approximately 2,000 feet to the north and on the same large Cambrian Knox structure.

Overnight the well was deepened an additional 120 feet to a total depth of 2,477 feet. The well is currently being logged and completion operations are underway. Production casing is scheduled to be run and cemented today.

Marksmen estimates there are at least an additional five drilling locations on the Davis-Holbrook 3D Cambrian Knox remnant on which the Davis-Holbrook #1 well was drilled.

Marksmen's 3D Seismic acquisition programs in Pickaway County have resulted in Marksmen selecting more than 20 Cambrian Knox target well locations. Additional 3D Seismic surveys are planned on Marksmen's leasehold interests in Pickaway County Ohio.

Results of production testing and other information will be announced when they are available.

For additional information regarding this news release please contact Archie Nesbitt, President, Chief Executive Officer and a Director of the Company at (403) 265-7270 or e-mail info@marksmen.ca.

Interesting article, they used seismic testing which I think is unusual in shallow formations, at least in Ohio.     Ohio indeed is "on the radar" for all types of oil and gas development as well as businesses related to it.
