Acid Fracturing - an overview | ScienceDirect Topics

Such a method consists of (Qu and Wang, 2010 ): 1. Injecting an acid fracturing fluid into the formation at a pressure sufficient to form fractures within the formation. The fluid comprises a, sulfonate ester,, a fluoride salt, a proppant, and water; the, sulfonate ester, is hydrolyzed to produce sulfonic acid. 2.

We compared water use for hydraulic ,fracturing, (HF) for ,oil, versus gas production within the Eagle Ford shale. We then compared HF water use for Eagle Ford ,oil, with Bakken ,oil,, both plays accounting for two-thirds of U.S. unconventional ,oil, production in 2013. In the Eagle Ford, we found similar average water use in ,oil, and gas zones per well (4.7–4.9 × 106 gallons [gal]/well).
