A unit of Ares Management LP is buying South Texas-focused BlackBrush Oil & Gas LP from EIG Management Co. LLC and Tailwater Capital LLC.

With new capital provided with the transaction, BlackBrush plans to further develop its more than 160,000 net (360,000 gross) acre position in South Texas, backers said. The transaction is expected to close in the third quarter and is subject to customary conditions. Financial details were not disclosed.

“BlackBrush is a unique opportunity consistent with our strategy of investing in best-in-class management and high-quality basins as part of the growth in domestic energy production,” said Nate Walton, principal in the Private Equity Group of Ares Management.

BlackBrush will continue to be led by CEO Scott Martin, who founded the company along with Phil Mezey, who will also remain involved as an adviser to BlackBrush. “Partnering with the Ares private equity team provides us the capital to continue developing and growing our large asset base,” Martin said.

BlackBrush executives were not available to provide further comment on the deal or their plans.

San Antonio-based BlackBrush was founded in 2004 and operates more than 160,000 net (360,000 gross) acres extensively throughout South Texas and is active in the Eagle Ford and other shale formations.
