SoCalGas provides update on infrastructure at Aliso Canyon NG facility
Southern California Gas provided an update on comprehensive infrastructure, technology and safety enhancements made at its Aliso Canyon natural gas storage facility. The company continues to make significant progress towards completing the Comprehensive Safety Review required by California's Division of Oil, Gas, and Geothermal Resources. In addition, the inner tubing of every approved well has been replaced. In total, more than 40 miles of new steel piping has been installed. Once SoCalGas has met all of the requirements of the Comprehensive Safety Review, the company will request regulatory approval to begin replenishing the supply of natural gas at the facility to support regional energy reliability. To date, 27 storage wells at the facility have passed all of the tests required under DOGGR's Comprehensive Safety Review. The remaining wells either have been temporarily and mechanically sealed off from the storage reservoir until further testing is completed or have been permanently plugged and taken out of service, in compliance with regulations and state law. In addition to being mechanically sealed from the pressure in the field, the wells also are filled with fluid that provides additional protection. Daily observation of these temporarily sealed wells will continue and they are also being monitored in real time for pressure changes. SoCalGas is a regulated subsidiary of Sempra Energy.
