Item 1.01 Entry into a Material Definitive Agreement.
West Williston Acquisition
On
September 4, 2013, Oasis Petroleum Inc. (the "Company") entered into a purchase and sale agreement (the "Purchase Agreement") with an undisclosed private seller, pursuant to which the Company will purchase 136,000 net acres
in the Williston Basin for approximately $1,450 million (the "Purchase Price"), subject to purchase price adjustments (the "West Williston Acquisition"). The Company currently expects to close the transaction during early October
2013, subject to obtaining required regulatory approvals and other customary closing conditions. The effective date for the transaction is April 1, 2013, with any purchase price adjustments to be calculated as of the closing date.
The West Williston Acquisition will increase the Company's reserves portfolio by approximately 43.9 MMBoe of proved reserves, of which
40% are developed. The West Williston Acquisition also adds approximately 136,000 net acres, of which 91,000 net acres are prospective for all depths, including the Bakken and Three Forks reservoirs. The acreage is generally in large contiguous
blocks and is 97% held-by-production. Additionally, the added acreage consists of 99 operated spacing units and 82 non-operated spacing units. Approximately 91% of the acreage will be operated, with an average working interest of 67%.
The Company expects to fund the Purchase Price of the West Williston Acquisition with borrowings under its revolving credit facility or,
subject to market conditions, proceeds from the issuance of private or public securities.
The foregoing description of the Purchase
Agreement is a summary only and is qualified in its entirety by reference to the complete text of the Purchase Agreement, which is filed herewith as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.
Credit Facility Amendment
On
September 3, 2013, the Company entered into an amendment to its Second Amended and Restated Credit Agreement with its bank syndicate (the "Amendment"). The lenders under the Company's revolving credit facility completed their
regular semi-annual redetermination of the borrowing base scheduled for October 1, 2013. Following the redetermination, the Company's borrowing base increased from $1,250 million to $1,500 million and elected commitments also totaled
$1,500 million. Additionally, the Company added four new lenders to the bank group. The next redetermination of the borrowing base is scheduled for April 1, 2014.
The foregoing description of the Amendment is a summary only and is qualified in its entirety by reference to the complete text of the
