California Regulators Propose Limiting Aliso Gas Storage

January 18, 2017 - storage organizer

California regulators on Tuesday due to “significantly limit” volumes of healthy gas that could be stored in a now shuttered Aliso Canyon field, a state’s largest subterraneous storage trickery on 3,600 acres with 86 Bcf capacity.

State officials pronounced a Southern California Gas Co. (SoCalGas) trickery could reopen, despite during a fragment of past capacity, as about one-third of a storage wells have upheld a battery of tests. Months of examination have now been finished by a state, and SoCalGas submitted a minute news seeking to reopen a trickery final November.

The Department of Conservation’s Division of Oil, Gas and Geothermal Resources (DOGGR) and a California Public Utilities Commission (CPUC) are proposing to need SoCalGas to accommodate some-more difficult reserve measures, such as equipping all wells with real-time monitors and alarms, and to protectively encase all of a 114 storage wells that eventually could be authorised to resume gas injections.

“We wish to hear a public’s thoughts on a contrast and inspections, and a stairs being taken to safeguard open health, reserve and environmental protection,” pronounced DOGGR arch Ken Harris, who also is a state oil/gas supervisor. “The whole trickery has undergone endless review and any good has been entirely tested with difficult standards that were grown with experts during Lawrence Berkeley, Lawrence Livermore, and Sandia Laboratories.”

The state’s latest examination arguable that 34 of a 114 storage wells have upheld a compulsory six-test series, and 79 others have been taken out of service, filled with protecting fluid, and are safely removed from a gas storage field. The additional wells have a year to pass all a tests or be henceforth plugged.

In further to a reserve slackening requirements, state officials pronounced they now trust that Aliso handling during a reduced ability would be sufficient for gas and electricity trustworthiness in a larger Los Angeles Basin. New conditions SoCalGas would have to accommodate if a trickery is reopened embody tying gas injection/withdrawals to wells’ prolongation tubing (inner steel pipe). Moving gas in and out of storage regulating a prolongation surrounding would no longer be allowed.

SoCalGas also would have to ensure:

  • Storage good heads be legalised daily regulating trickle showing technology;
  • Storage ability be singular to 29 Bcf;
  • At a smallest 15.4 Bcf of gas volumes be in storage; and
  • Maximum handling pressures sojourn next those requested by a utility.

Harris told reporters during a discussion call on Tuesday there is no aim date for completing a ongoing review into a causes of a trickle final year. No new injections would be authorised “until a surrounding communities and endangered open have an event to import in.”

Regulators devise to reason open hearings Feb. 1-2 nearby a Porter Ranch growth adjacent Aliso Canyon. Some citizen organizations are still anticipating to force a facility’s permanent closure. Late Tuesday, a Food Water Watch (FWW) and Save Porter Ranch village organisation reiterated their claims that a 45-year-old gas storage trickery can't be done protected again. “We are prepared to quarrel to keep a storage trickery sealed and safeguard it is decommissioned,” pronounced FWW comparison organizer Alexandra Nagy.

Save Porter Ranch President Matt Pakucko indicted state regulators of perplexing to “rush” a reopening and claimed that no one knows a means of last winter’s four-month methane leak.

Elected officials have pronounced they can't support reinjecting gas during Aliso until a review news and open hearings are concluded. Los Angeles County Supervisor Kathryn Barger, who represents a Porter Ranch area, pronounced she can’t support reopening a trickery until a causes of a trickle are famous .

CPUC and DOGGR officials stressed that they will continue to work in tandem “to safeguard a reserve of a margin and will attend in a meetings to plead a facility’s purpose in ensuring that a larger Los Angeles area has a arguable supply of healthy gas.”

They expel aside concerns about a normal age of a wells during Aliso, observant that isn’t a reserve factor. “It is all about tests; some of a wells can be aged and still be in unequivocally good shape, and others might not be, it is unequivocally a side-by-side, well-by-well situation,” Harris said.
