About the PlayEagle Ford

The Eagle Ford formation stretches across a wide swath of South Texas and represents a more mature stage of development than our other U.S. resource plays. Six years after we entered the region, our focus has transitioned from rapid growth to efficient development and capturing cash flow from existing wells. Our incremental but steady improvement in drilling efficiencies has been achieved through process optimization, the use of high-spec rigs and experienced crews, and numerous small innovations.

Our advanced SCADA and digital operating control center drives increased efficiency through automated production trend monitoring and automated alerts on our 1,500 producing wells. Roughly two-thirds of our acreage is located in Karnes and Atascosa counties. 

We brought fewer wells to sales in 2017, while we increased well productivity through completion optimization and efficiency gains. 

Latest Activity4Q 2017

Our production in the Eagle Ford averaged 105,000 net boed in 4Q 2017, up from 101,000 net boed in the prior quarter. We brought 33 gross Company-operated wells to sales in 4Q with average 30-day initial production rates of 1,800 boed (73% oil). The testing of enhanced completion designs in Atascosa County continued to deliver encouraging results.
