Marksmen Energy Inc. and its wholly owned subsidiary, Marksmen Energy USA, Inc. announced that drilling has commenced on it's Leaman 1-H Clinton Sandstone Horizontal well in Hocking County, Ohio. The well is expected to reach total depth by January 31, 2018. The working interest partners in the well, through the operator, Hocking Hills Energy and Well Services LLC (HHEWS) has entered into an agreement with BATTELLE MEMORIAL INSTITUTE (Battelle). As part of this research portfolio, Battelle is executing a project in conjunction with the Ohio Development Services Agency (ODSA) through the Ohio Coal Development Office (OCDO). This project is to investigate the potential for CO2 storage in Ohio's depleted oil and gas fields, storing CO2 and performing enhanced oil recovery (EOR) simultaneously. Battelle has agreed to participate in Marksmen's (60% working interest) exciting ground-breaking Leaman 1-H well in Hocking County, Ohio. They will evaluate the prime target for CO2 storage and concurrent EOR operations is in Hocking County's Gore Consolidated Oilfield. The Gore Consolidated Oilfield produces from the Clinton Sandstone and can be considered a primary target for CO2 storage evaluation because of relatively poor (10-15%) primary recovery of the oil in place, leading to many reserves remaining to be exploited. Battelle will participate in the new well planned for Washington Township, Hocking County, the Leaman 1-H well. This well will be the first of its kind in Hocking County and the Gore Consolidated Oilfield, presenting a unique opportunity to collect never-before available data. The Leaman 1-H well will be a horizontal Clinton oil well. This well presents the opportunity to explore untapped oil and to realize the potential of horizontal completions in the Clinton Sandstone in Hocking County. Battelle's participation includes data collection that has not yet been performed on any horizontal Clinton well in Ohio. Following drilling, Battelle will run a suite of wireline tools to collect valuable downhole data, including running a triple combo log to assess porosity and other geologic characteristics and an acoustic log to assess geo-mechanical properties (critical to understanding formation mechanics for potential CO2 storage). Following the wireline logging tool deployment, Battelle will run a series of downhole pressure reservoir tests to evaluate the permeability profile and investigate downhole fluid saturation and movement. This information is valuable for potential CO2 storage, but will inform production potential and show targeted areas for high permeability, completion targets for production.
