Penn Virginia Corp.’s 40% working interest partner in its Lavaca County, TX, Eagle Ford Shale acreage has elected to go “nonconsent” on the last 17 initial unit wells on the acreage. Penn Virginia said it will seek a partner to acquire the 40% working interest. Of 17 initial unit wells, seven have been drilled, two are being drilled and eight remain to be drilled, the company said. The current working interest partner will have no participatory rights in any subsequent wells drilled in the unit. As a result, Penn Virginia’s net Eagle Ford acreage in Lavaca County will increase from about 9,200 acres to about 13,400 acres upon the drilling of all of the initial unit wells. “We expect that each of the drilling units will support up to an additional four primary development wells after the initial well,” Penn Virginia said. “To date, our Lavaca County wells have generally met or exceeded expectations with average reserves of approximately 500,000 boe and attractive economics.” In October, Penn Virginia acquired about 4,100 net Eagle Ford acres in Gonzales and Lavaca counties for about $10 million. Other nonoperated working interest owners were expected to acquire some of the acreage (see Shale Daily, Oct. 4). One year ago, the company said it was exploring the Eagle Ford with an undisclosed “major oil and gas company” (see Shale Daily, Dec. 21, 2011).

Gas operations include the McArthur River, Ninilchik, Cannery Loop and Kenai Gas units, as well as Beaver Creek, which is an oil and gas development within the Kenai National Wildlife Refuge. The sales package also includes natural gas storage and gas pipeline transmission systems. Last year Marathon’s Alaska net production averaged 93 MMcf/d of gas and 112 b/d of oil. The company also had about 12.5 Bcf in storage at the end of 2011. The transaction, with an effective date of Jan. 1, 2012, is set to be completed this fall. Not to be sold is Marathon’s onshore drilling rig, which is being marketed separately.
