Antero

Prometheus Energy Group Inc. announced that it had signed a multi-year agreement to supply Antero Resources with enough liquefied natural gas (LNG) to power “a significant portion” of Antero’s natural gas-fueled drilling rigs in the Marcellus and Utica shales.

Antero Resources LLC, now preparing to become a publicly traded explorer, already oversees one of the biggest operations in the Appalachian Basin, and it wants to keep it that way by building a 150-mile-long water sourcing and distribution pipeline that would feed drilling sites across West Virginia and into Ohio.

A district court judge wants the highest court in West Virginia, the Supreme Court of Appeals, to certify whether existing state law allows a company to drill on land where it doesn’t own the surface rights, but it owns the underlying mineral rights.

Pennsylvania state Rep. Jesse White (D-Cecil), who has frequently voiced his opposition to the state’s omnibus Marcellus Shale law and the potential impacts of gas drilling in the state, sent e-mails to Range Resources Inc. — the largest driller in his home county — asking for campaign contributions and a ride to the 2011 Superbowl on Range’s corporate plane.

Houston-based Vanguard Natural Resources LLC has closed on its acquisition of natural gas and liquids assets in the Arkoma Basin from Antero Resources for an adjusted price of $434.4 million, subject to post-closing adjustments. The effective date is April 1, 2012. The deal was announced early last month (see Shale Daily, June 5). Vanguard funded the acquisition with borrowings under its existing reserve-based credit facility. The borrowing base was increased from $670 million to $975 million in connection with an interim borrowing base redetermination to include the properties from the acquisition. Updated 2012 production and financial results guidance will be included with second quarter results, which are expected to be released on Aug. 2.

MarkWest Energy Partners LP is building out its services for Appalachian rich-gas producers with the $512 million acquisition of Pennsylvania-based Keystone Midstream Services LLC.
