Professor of Engineering Emeritus at Cornell University, about the Risks to the climate, the environment, and investors continue to mount. Once again, this cost-cutting approach hasn’t been working, and the Limits of technology to try to finally turn a profit and pay back their Same issues that have caused past failures: cutting corners on costsīecause shale companies have been losing money and are pushing the This growing problem for the fracking industry can be traced to the Industry players, including Shell, BP, and XTO, the subsidiary of ExxonMobil that operated the blown well in Ohio. Tackling this issue is made up of representatives from the major This is not some fringe issue for independent operators. Issue at its February 6 meeting in Texas during a three-hour panelĬalled ” Casing Deformation in Unconventionals: Case Histories, Root-Causes, Managing and Mitigating.” The Society of Petroleum Engineers itself will be discussing this Occurring during fracture stimulation operations are increasing at anįor an industry laser-focused on cutting costs, the risk of losing an entire fracking well gets its attention. Strong language (for engineers), noting, “Incidents of casing failures Hazardous problem. This paper identified the problem in depth and used Linked to the stresses and high pressures required to complete theįracking process and the industry is grappling with this costly and Petroleum engineer Neal Adams and others, casing failures have been Credit: Environmental Protection Agency, public domainĪccording to the Society of Petroleum Engineers paper, produced by Representation of a horizontally drilled and hydraulically fractured natural gas well, with the cycle of water involved. Rock, creating fractures that allow trapped oil and gas to flow up the This is accomplished by pumping a mixture of water,Ĭhemicals, and sand under such high pressure that it breaks apart the The process of hydraulic fracturing is what releases the oil and gasįrom the shale. Gas, and fracking fluids that pass through the well. Vertical portion is made up of several layers of steel pipe casing andĬement that are designed to protect nearby groundwater from the oil, Well, at a certain point, the well bore turns and drills horizontallyįor distances up to 20,000 feet (that’s nearly four miles). While a fracked well is initially drilled vertically like a conventional What are known as “conventional,” or traditionally drilled, oil wells. Wells used to produce oil and gas via fracking are different from Injuries/fatalities, and loss of the well with associated costs.” Out: “Outcomes from casing failures include blowouts, pollution, The results of these failures can be catastrophic, as a 2017 paper published by the Society of Petroleum Engineers spells
Where hydraulic fracturing, or fracking, is happening. Such as fracking fluids - to leak into the surrounding environment. TheyĬan take place, as in the example of Exxon’s gas well in Ohio, at sites Pressure anymore and creates a pathway for anything inside the well . Or gas well breaks or cracks, which means the well can’t maintain Fracking and when well linings failĬasing failures occur when the steel or cement that’s lining an oil The cause of this massive leak was a failure of the gas well’s casing, or internal lining. Well casing failures represent yet another significant but not widely discussed technical problem for an unprofitable fracking industry. Methane released by the oil and gas industries in countries like Norway Leaked more methane in 20 days than an entire year’s worth of In December that new satellite data revealed that this single gas well On February 15, 2018, a fracked natural gas well owned by ExxonMobil’s XTO Energy and located in southeast Ohio experienced a well blowout, causing it to gush the potent greenhouse gas methane for nearly three weeks. The obscure accident ultimately resulted in one of the biggest methane leaks in U.S.
