Gov. John Kasich on Tuesday touted the economic potential of Ohio's Utica shale in his State of the State speech in Steubenville.
The governor also announced plans for two gas-processing facilities: one in Harrison County and one in Monroe County.
MarkWest Energy Partners LP is partnering with the Energy & Minerals Group to form MarkWest Utica EMG LLC on the two projects that will together cost about $500 million.
The project calls for two so-called processors that will separate natural gas from oils and wet gases like butane, propane and ethane from Ohio's Utica shale. A third unit, a fractionation complex, will separate the oils from ethanes, a key ingredient in making plastics.
Construction of the two plants and connecting pipelines is expected to create about 700 construction jobs. The plants will employ about 40.
The companies have not identified locations but have said they hope to have the plants operating in 2013.
The Harrison County complex would process up to 200 million cubic feet of gas per day and 100,000 42-gallon barrels of oil and other liquids per day, MarkWest Energy said. The Monroe County complex is still under design.
Additional processing complexes are anticipated as drilling develops in eastern Ohio, the company said.
