RE:Positive based on Surge's 2P 2013 estimateRPL states the sale of " mature" assets while Surge describes them as "low decline, 10 year reserve life, accretive assets" with battery, pipeline and water flood infrastructure".
These may be former Penn West assets that need a lot of maintenance costs and do not fit well with the new, slimmer RPL that high debt load will mandate. Also, the deal requires attractive assets to entice a buyer in this M+A climate so maybe we are fortunate.
