World Oil's Eagle Ford / Austin Chalk map published in March 2019. Often referred to as the little brother of the Permian basin, the Eagle Ford shale came of age during the five-year U.S. unconventional boom of 2010-2014. Operators were lured to plentiful reserves of oil, gas and condensate. The rapid development and oil production growth, accompanied by traffic snarls and a worker housing shortage, came to a grinding halt at the end of 2014, when the oil price crashed.
The region's rig count, which once hit a peak of 259 during the boom days, fell to a low of 29 in May 2016, but has now recovered to a count of approximately 80. Benefitting from the Permian’s shortage of takeaway capacity, the Eagle Ford is now estimated by the USGS to hold 8.5 Bbbl of oil, 66 Tcf of natural gas, and 1.9 Bbbl of NGLs that are "undiscovered" and "technically recoverable."
