BigTex firms Locke Lord, Vinson & Elkins, and Akin Gump Strauss Hauer & Feld are representing WildHorse Resource Development in its pending $625 million purchase of Eagle Ford assets from Anadarko Petroleum Corp. and affiliates of Kohlberg Kravis Roberts & Co. (KKR). Two out-of-state firms with Texas offices represent the other side, with Sidley Austin representing Anadarko and Kirkland & Ellis advising KKR on the deal.

The Eagle Ford Shale is considered the largest oil & gas development in the world.

On May 11, Houston-based WildHorse announced a definitive agreement to acquire about 111,000 net acres and associated production from Anadarko and the KKR affiliates. Terms of the agreement call for WildHorse to pay $556 million in cash to The Woodlands-based Anadarko and provide 6.3 million shares of WildHorse common stock valued at about $69 million to KKR. The transaction is expected to close by June 30, with an effective date of Jan. 1.
