In all, President Obama has okayed over 1,500 offshore fracking permits in the Gulf of Mexico as of summer 2016. According to Schlumberger, drillers had avoided these formations because of the poor seismic data. A subsalt is a play underneath a layer of salt. The Gulf of Mexico has several subsalt oil reserves. The US Department of the Interior must reveal records on the use of fracking technology in the Gulf of Mexico under a legal settlement with an environmental group, Center for Biological Diversity, filed in federal court on June 1, 2015. This can make hydraulic fracturing environmentally risky. Many of the leases were in the Lower Tertiary Basin, an area of hard-to-penetrate rock where the crude is located in deep wate. In August 2014 the federal government sold more than 400,000 acres in the Gulf of Mexico off the Texas coast for oil and gas. Chevron claims it drills to reserves at almost six miles below the seafloor. It is more established and typically smaller in scale than the large, horizontal hydraulic fracturing operations.Ĭhevron claims fracks at its deepest Gulf water sites. It uses high pressure water, gravel and chemicals to clear sand from the opening of the well and allow fossil fuels to flow. Frac packing has been used offshore for decades. The BSEE list released in 2014 indicated a fracking process known as "frac packing" was deployed during 2013. The BSEE also indicated that fracking occurred near the 2010 BP Deepwater Horizon spill. In 2014, federal regulators at the Bureau of Safety and Environmental Enforcement (BSEE) released a partial list of 115 hydraulic fracturing sites in the Gulf of Mexico revealed that BP, ConocoPhillips, Shell and nearly two dozen other drillers were approved to use offshore fracking in 2013. Offshore fracking can sometimes involve using seawater rather than fresh water along with sand and chemicals. federal waters, three miles offshore, from land produced 528,447 barrels (22.2 million gallons) of crude oil. 6 Offshore Hydraulic Fracturing Providers.2.6.1.1 Santa Barbara All American Pipeline Spill.
