Estimated total net proved reserves are 13.1 billion cubic feet equivalent (4.3 billion cubic feet equivalent net proved developed producing). Net production is 3.9 million cubic feet per day of gas (650 barrels of oil equivalent) per day.

Endeavor chief executive and president William L.

It is also the beginning of a valuable relationship with J-W and Cohort which has been very successful in several domestic resource plays.”
