U.S. Energy Department assesses oil production from Eagle Ford shale in southern Texas. UPI/Gary C. Caskey WASHINGTON, Sept. 29 (UPI) — Oil production from the Eagle Ford shale play should increase with improved drilling efficiency, though the area is prone to declines, analysis Monday finds. The U.S. Energy Information Administration, a division of the Energy Department, said the increase in drilling and improvements in drilling efficiency have led to more oil from the Eagle Ford shale region in southern Texas. “These increases have occurred despite the region’s relatively high well decline rates,” an EIA briefing said. “However, by offsetting the natural declines through the use of new recovery techniques, further production increases are possible.” The Texas government said oil production in July, the last full month for which data are available, increased more than 25 percent year-on-year to around 2.15 million barrels per day thanks in part to production […]
