Lenders for Oasis Petroleum Inc. (NYSE: OAS) increased the aggregate elected commitment for the company’s borrowing base to $1,525 million, up from $1.5 million, the company said April 14. The borrowing base is at $1.7 million after the semiannual redetermination, the company added.

If one or more lender’s commitment is increased, the aggregate commitment can be increased to match the borrowing base.

The borrowing base facility is supported by 18 financial institutions.

The next redetermination is scheduled for Oct. 1.
