Ohio got its first look on Monday at production numbers from the Utica shale, and the numbers remain very promising.
The "general production is significant, even with early production numbers" from natural gas wells, said the Ohio Department of Natural Resources’ Division of Oil and Gas Resources Management.
The data covered nine wells drilled by Oklahoma-based Chesapeake Energy: six in Carroll County and one each in Portage, Harrison and Mahoning counties.
Five of those wells are in production and produced nearly 2.6 billion cubic feet of natural gas in 2011, plus 43,513 barrels of oil.
The Buell well in Harrison County produced 1.5 billion cubic feet of natural gas or 2 percent of the natural gas produced in Ohio in 2011 by 49,000 convention wells.
The well has 300 times more in daily production than the average well drilled vertically into the ground, said Rick Simmers, chief of ODNR’s Division of Oil and Gas Resources Management.
"The preliminary production for all the wells on the gas side is very high," he said.
The reported volumes of oil are lower than estimated but higher than convention wells, the state reported.
A typical vertical well in Ohio annually produces about 50,000 cubic feet on gas per day and less than 1 42-gallon barrel of oil.
The five wells were in service from 53 to 206 days in 2011.
The other four wells produced zero natural gas in 2011, but oil was recovered during completion/flowback in 2011. The four wells each produced less than 1,000 barrels of oil in 2011. The Portage well in Suffield Township produced 583 barrels of oil.
Monday’s report covers wells that were drilled and put into production before Dec. 31. The data had to be submitted to the state by Friday.
The report offers the first official production data from Ohio’s Utica shale wells.
Until now, most production data has been tightly held by drilling companies.
