Jim McKinney, senior vice president and general manager from EnerVest, a Houston-based company, said his company believes that with changes in drilling techniques, activity will increase in the oil-rich northern part of the Utica Shale, which includes Trumbull County.
“When companies first drilled, they were using the same techniques they were using in the dry- and wet-gas areas of the Utica,” he said.EnerVest has found in Tuscarawas and Guernsey counties that by using more water and sand in the fracking process, there can be success in the oil-rich portions of the Utica, McKinney said.“Oil has different molecules than gas,” he said.
Companies were using 200 feet to 250 feet spacing between injections, but for the oil area it needs to be shorter, about 150 feet, McKinney said.
“It allows the oil to move more freely toward the well bore,” he said.If the tests for EnerVest are successful, there will be companies interested in leasing land in Trumbull and Stark counties, McKinney said. Trumbull and Stark counties are thought to be areas with oil-rich shale.
