Oasis agreed to sell certain properties targeting the Sanish prospect in the Williston basin for around $333 million. The assets consisted of 8354 net acres and fourth-quarter production of around 2691 barrels of oil equivalent per day on 28.2 net wells.
The buyer was undisclosed and the deal is expected to close next month.
Chief executive Thomas Nusz said funds from the sale would improve Oasis' liquidity and would allow the company to execute its accelerated drilling programme in 2014.
