SoCal Gas announced Monday that it has started the process of permanently sealing its leaking well at the Aliso Canyon storage facility, a leak which led to many residents of Porter Ranch leaving their homes.

"We will be working with [the California Division of Oil, Gas and Geothermal Resources] to complete a diagnostic process to confirm that the cementing process was successful and the well is permanently sealed," SoCal Gas senior vice president Jimmie Cho said in a press release.

The gas company has been drilling a relief well since Dec. 4, according to the company. The company pumped heavy fluids in order to temporarily block the leak last Thursday, then began pumping cement down to permanently seal the well on Friday, according to the release.

It could take several days for state officials to confirm the well has been permanently sealed, according to the release. The methane levels in the area dropped on Feb. 11 after the well was temporarily sealed, according to the Air Quality Management District.

The company says that residents shouldn't experience any symptoms related to gas now that the well has been sealed. Residents are scheduled to be given eight days to leave temporary housing paid for by SoCal Gas once the well has been confirmed sealed.
