Aliso Canyon Gas Leak - Incident Update - February 10, 2016

Feb 10, 2016

LOS ANGELES, Feb. 10, 2016 /PRNewswire/ --

SoCalGas Operations Update — SoCalGas continues to make progress on relief well number one, reaching a measured depth of 8,615 feet.  As we move forward, there are three major milestones – the "three C's" – to stopping the leak:

  • Controlling the natural gas that is leaking:
    • This step consists of approaching the target well along the most precise path possible so the drill bit is in the best position to drill through it, and then pumping heavy fluids into the target well to stop the flow of gas.
    • We expect this step to begin within the next several days.
  • Cementing and stabilizing the target well so that it is permanently sealed:
    • When the flow of gas has been stopped, SoCalGas will pump enough cement to displace the fluids and mud and leave a cement seal that will cut off the target well from the reservoir, permanently stopping the leak at its source.
    • This step will take multiple days after controlling the flow of gas.
  • Confirmation from DOGGR that the target well is permanently sealed:
    • SoCalGas will work with the regulating agency, the Division of Oil, Gas and Geothermal Resources to confirm that the well leak is permanently stopped.
    • At that point, it is anticipated that no more gas will leak from the well and any remaining odors associated with the leak are expected to quickly dissipate.
    • This step will take multiple days after cementing the well.

We remain on schedule with relief well number one to stop the leak by late February or sooner.  Crews continue to set up rig equipment on relief well number two.

SoCalGas Notification to Residents
SoCalGas will make at least two notifications to residents. The first will be when the leak has been controlled. The second will be when SoCalGas receives confirmation from DOGGR. SoCalGas will attempt to call or email all residents who requested relocation assistance from SoCalGas as well as issue a press release, post information on the and provide updates through social media.
