Oil production in the Eagle Ford shale region in Texas continues to increase due to more drilling operations and improved drilling efficiency. The region also generated more than $87 billion in economic output last year, according to the University of Texas at San Antonio.
Producers in the region have raised the amount of horizontal drilling as well as hydraulic fracturing operations in the Eagle Ford, which has made it possible to increase production despite well decline rates, the UTSA stated. First-year decline rates in the Eagle Ford have moved between 60 and 70 percent, but second-year decline rates have increased from 30 percent in 2009 to 50 percent in 2011 and 2012.
Typically, wells will have high production rates at the beginning, then see large decline rates until they level off. The increased output and faster decline in Eagle Ford shale wells can be attributed to fracking, which is known to increase initial production rates then causes a severe drop in production.
In 2013, the Eagle Ford supported nearly 155,000 full-time jobs, according to UTSA. The oil production activity has created more than $4.4 billion dollars for local and state governments. UTSA predicts the region will support more than 196,000 positions by 2023.
