FORT WORTH, Texas and NEW YORK, May 16, 2017 /PRNewswire/ — Chisholm Energy Holdings, LLC (“Chisholm” or “the Company”), a start-up oil and gas company, today announced that it has closed on the acquisition of its first asset, located in the New Mexico region of the Delaware Basin. The asset, located in Eddy and Lea counties, includes a substantial amount of highly attractive undeveloped acreage with multiple targets in the Bone Spring and Wolfcamp formations. The asset was acquired from a private seller.

Terms of the transaction were not disclosed.

Formed in May 2016 and headquartered in Fort Worth, Texas, Chisholm is focused on the northern Delaware Basin. Chisholm is backed by a $500 million line-of-equity from Warburg Pincus, a global private equity firm focused on growth investing.
