Sanchez Energy Corp. (NYSE: SN) closed its acquisition of Eagle Ford assets from wholly owned subsidiaries of Royal Dutch Shell Plc (NYSE: RDS-A, RDS-B), the company said June 30.

The acquisition, which had an effective date of Jan. 1, totaled about $553.5 million, Sanchez said. About $85.5 million in closing adjustments had been deducted from the $639 million purchase price, the company noted. The $553.5 million included the deposit of about $51.1 million, the company added. The final purchase price depends on more adjustments after closing, Sanchez said.

Cash, along with the net proceeds from the offer of $850 million senior unsecured 6.125% notes due 2023, funded the acquisition, the company said.

Additionally, Sanchez said that it closed its second amended credit agreement. The $1.5 billion agreement received $425 million in available commitments, the company noted, adding that the facility does not have outstanding loans.

"This strategic acquisition adds significant reserves, production and future resource potential in an area of the Eagle Ford Shale where we have demonstrated an ability to rapidly assimilate and efficiently develop acquired properties. We believe that our recently completed equity and notes capital raises, along with our new bank credit facility, will leave us in a financial position of considerable strength to execute our plans," said CEO and president Tony Sanchez III.

Houston-based Sanchez Energy Corp. operates in the Tuscaloosa Marine and Eagle Ford Shales.
