Upon completion of the transaction, Linn will have remaining production of about 8 MBoe/d and around 6,600 net acres in the Midland Basin that is prospective for horizontal Wolfcamp drilling.
Both the transactions are expected to be completed in the fourth quarter of 2014.
Linn Energy chairman, president and chief executive officer Mark Ellis said: "One of our goals for 2014 was to maximize value for our Midland Basin and Granite Wash assets in order to reduce the capital intensity and decline rate within our portfolio. We believe today’s announcements largely accomplish this goal.
"When considered in light of the accretive acquisitions and trades we’ve announced this year, we are very excited about our business as we move into 2015."
