Bayou City Energy has acquired a stake in High Mesa Inc., an established operator in Oklahoma's Stack Play, the company said Sept. 12.

BCE-MESA Holdings LLC, an affiliate of the Houston company, completed the purchase of preferred stock in High Mesa for an undisclosed amount.

High Mesa is a privately held company with interests in oil and gas assets, notably Alta Mesa Holdings LP. Alta Mesa has more than 95,000 net acres in the Stack in Kingfisher County, Okla., and is currently producing about 16,000 barrels of oil equivalent per day, the release said.

In connection with the investment, High Mesa appointed William McMullen, founding partner of Bayou City Energy, to its board of directors. Bayou City Energy previously formed a drilling joint venture with Alta Mesa and HPS in January, McMullen said.
