Emerald Oil Inc. (NYSE MKT: EOX) has closed the previously announced acquisition of core Williston Basin properties. The total consideration paid for the acreage was approximately $109 million, subject to customary closing adjustments, consisting of approximately $70.2 million in cash and the assignment of approximately 4,250 net acres located in Williams County, N.D.

In conjunction with the closing of the transaction, Emerald and its lending syndicate entered into an amendment to the company's credit facility to increase the borrowing base under the credit facility from $100 million to $200 million. This redetermination reflects both Emerald's completion activities through the second quarter of 2014 and the transaction. The facility is currently undrawn. Emerald expects the next borrowing base redetermination to take place in October 2014.

Emerald Oil is based in Denver.
