Warburg Pincus and Kayne Anderson-backed Ensign Natural Resources, a private equity firm, agreed to acquire Eagle Ford Shale Acreage from Reliance Eagleford Upstream, a wholly owned step-down subsidiary of Reliance Industries. Financial terms were not disclosed. "Through our efforts over the last three years, we have created an asset that generates significant free cash flow and has a deep inventory of highly economic well locations in the core of the Eagle Ford Shale. We are excited to complete the puzzle with the acquisition of Reliance's interest and now operate one of the premier assets in the basin. We look forward to future development of the asset and working closely with our service providers and landowners as we continue to grow the business in a safe and efficient manner," Brett Pennington, Ensign President and CEO.
