Evolution Petroleum (EPM) said late Monday it closed the acquisition of non-operated oil and natural gas assets in New Mexico, Texas, and Louisiana for $9 million.

The seller of the assets was not disclosed.

The acquisition, effective Feb. 1, was funded through a combination of cash and borrowings under the company's existing credit facility, Evolution said.
