SoCalGas Issues Statement on Blade's Analysis of Aliso Canyon Well Failure
May 17, 2019
LOS ANGELES, May 17, 2019 /PRNewswire/ -- Earlier today, Blade Energy Partners (Blade) published a report detailing its analysis of the 2015 natural gas leak at SoCalGas' Aliso Canyon storage facility. The investigation was conducted at the direction of the California Public Utilities Commission and the Division of Oil, Gas and Geothermal Resources.
The report concluded that a rupture in the outer casing of the well occurred on the morning of October 23, 2015, followed hours later by a complete separation of the casing. According to the report, microbial induced corrosion caused the metal in the outer casing to thin, which led to the rupture.
Blade's report confirms SoCalGas complied with gas storage regulations in existence at the time of the leak. Blade also determined that SoCalGas' current practices and new state regulations address most, if not all, of the causes identified in the report. SoCalGas is still reviewing the report and issued the following media statement in response to the report's release:
"The release of this report marks an important milestone in helping the region and California move forward from the Aliso Canyon natural gas leak. The leak was an industry changing event resulting in the development and implementation of enhanced safety regulations and practices.
"Today Aliso Canyon is safe to operate and Blade's report indicates the industry leading safety enhancements and new regulations put in place after the leak should prevent this type of incident from occurring again.
"While we are still reviewing the report released today, we appreciate Blade acknowledging SoCalGas' full cooperation and support.
"Within two days of discovering the leak, we brought in Boots & Coots, the world's preeminent well control company, best known for controlling hundreds of wells during the Persian Gulf War. The leak at Aliso Canyon was stopped on February 11, 2016.
"In the months after the leak was stopped, SoCalGas and state regulators, who worked in consultation with independent experts at the U.S. Department of Energy's National Labs, conducted a comprehensive safety review at Aliso Canyon. That review and safety enhancements SoCalGas completed have been recognized as the most rigorous and comprehensive in the nation.
"The Blade report confirms SoCalGas complied with gas storage regulations in existence at the time of the leak and that the related compliance activities conducted prior to the leak did not find indications of a casing integrity issue. In Blade's opinion, there were measures, though not required by the gas storage regulations at the time, that could have been taken to aid in the early identification of corrosion and that, in their opinion, would have prevented or mitigated the leak.
"We look forward to reviewing the report in detail and to receiving the supplementary reports, so we can better understand the technical basis for some of Blade's conclusions."
