On Monday, Oklahoma-based Gulfport Energy Corp. announced completion of an agreement with MarkWest Utica EMG LLC to build and operate gas-gathering pipelines and processing facilities tied to Gulfport's Utica-shale acreage in eastern Ohio.
MarkWest plans to process the natural gas at a complex in Harrison County and will provide fractionation or processing servces for natural-gas liquids in Harrison County.
Initially, MarkWest will bring on line in interim refrigeration gas-processing plant in the third quarter of 2012.
That facility will be followed by a 125 million cubic-feet-per-day permanent cryogenic gas-processing plant that is expected to begin operations by the first quarter of 2013, Gulfport reported.
An additional capacity of 200 million cubic feet per day of cryogenic capacity wil be available by early 2014.
MarkWest is expected to have about 60 miles of related pipelines to move Gulfport volumes by the end of 2012.
By 2014, MarkWest should have 140 miles of gas-gathering lines and 20,000 horesepower of compression, Gulfport said.
By early 2014, MarkWest's facilities will include 325 million cubic feet per day of cryogenic gas-processing capacity in Harrison County and 100,00 barrels per day of ethane fractionation.
MarkWest is also developing a second processing complex in Ohio's Noble County.
Interim capacity of 45 million cubic feet per day is expected. The plant should begin operations in the fourth quarter of 2012.
A permanent facility with a daily capacity of 200 million cubic feet per day should be operational by mid-2013.
The Harrison and Noble processing complexes will be tied via pipelines to the Harrison fractionation complex. It will have a capacity of 100,000 barrels per day by the first quarter of 2014.
The Harrison fractionation complex will be connected to MarkWest's Houston fractionation complex in western Pennsylvania.
The Houston and Harrison fractionation complexes will be the largest in the Northeast, Gulfport said.
Gulfport has drilled three horizontal wells in eastern Ohio.
MarkWest is not the only company planning processing facilities in eastern Ohio.
Chesapeake Midstream Development andf two partners, M3 Midstream (Momentum) and EV Energy Partners, have announced plans for a $900 million complex in Columbiana and Harrison counties.
A state-of-the-art cryogenic processing plant for natural gas with an initial capacity of 600 million cubic feet per day in planned in Columbiana County.
The natural gas liquids would go to a central hub in Harrison County where 90,000 barrels a day would be processed.
Processing could begin in the second quarter of 2013.
"Aside from the economic growth and increase in job creation we've already seen coming in from development, at this early stage in the play these investments are another great indicator of the future, long-term potential of Ohio's resources in the Uticas shale. These companies are investing for the long haul," he said.
