As a Southern Californian familiar with this ongoing long-term (not coming) energy issue, for a quick response I used Freespoke AI, asking: WHAT OIL RIGS OFFSHORE SOUTHERN CALIFORNIA HAVE BEEN REACTIVATED AND PROVIDING OIL FOR SOUTHERN CALIFORNIA FEW REFINERS?

Consensus
Reactivated Oil Rigs Offshore Southern California
Sable Offshore Corporation, a Houston-based company, has restarted oil production from the Santa Ynez Unit off the coast of Santa Barbara, California. This unit includes offshore oil rigs in federal waters and a pipeline network that runs along the Santa Barbara County coast and inland to the Las Flores Canyon Processing Facility. Production had been offline for a decade following a major oil spill in 2015. Sable Offshore plans to sell 50,000 barrels of oil per day, anticipating sales to begin by April 1.
Sable Offshore has indicated that two additional oil rigs, Platform Heritage and Platform Hondo, are expected to resume operations soon. The oil extracted from these platforms, which are in federal waters, will be transported via the Santa Ynez pipeline from the Santa Barbara area to the Central Valley and refined at one of Chevron’s California refineries, specifically the El Segundo location.
Perspectives
----------------------------------------------------------------------------
I also asked: How many refineries in California have been shut down and reduction from peak supply?
California Refinery Closures and Capacity Reduction
California has seen a significant reduction in the number of operational oil refineries over several decades. In 1982, there were 43 refineries in California. This number decreased to 23 in 2000, and by early 2026, the state had 12 operating facilities. It is projected that this number will further drop to 11 by the end of 2026, and potentially to seven by the end of 2026.
Recent and planned closures include the Phillips 66 refinery in Los Angeles, which was preparing to close by the end of October 2025 and shuttered at the end of 2025. Valero also announced the closure of its Benicia refinery by April 2026. These two closures represent a combined loss of approximately 17% to 17.5% of California’s total in-state refining capacity, impacting the state’s fuel supply and the West Coast. This reduction accounts for 284,000 barrels per day of total capacity.
The state’s oil production has also experienced a substantial decline, with in-state oil production falling by 69% from its peak in 1985 to a historic low in 2023. California now produces about 20% of the crude oil it consumes, with over 65% coming from foreign sources. The closure of these refineries is expected to have an impact on gasoline prices and the overall energy landscape in the state.

For those interested, here’s Sable Offshore news release on 05/19/2025:
https://sableoffshore.com/news/news-details/2025/Sable-Offshore-Corp–Reports-Restart-of-Oil-Production-at-the-Santa-Ynez-Unit-and-Anticipated-Oil-Sales-from-the-Las-Flores-Pipeline-System-in-July-2025/default.aspx
HOUSTON–(BUSINESS WIRE)-- Sable Offshore Corp. (“Sable,” or the “Company”)(NYSE: SOC) today announced that as of May 15, 2025, it has restarted production at the Santa Ynez Unit (“SYU”) and has begun flowing oil production to Las Flores Canyon (“LFC”). Additionally, with the completion of the Gaviota State Park anomaly repairs on the Las Flores Pipeline System (the “Onshore Pipeline”) on May 18, 2025, Sable has now completed its anomaly repair program on the Onshore Pipeline as specified by the Consent Decree, the governing document for the restart and operations of the Onshore Pipeline.
Seven of the eight sections of the Onshore Pipeline have been successfully hydrotested. Sable will complete the final hydrotest in order to meet the final operational condition to restart the Onshore Pipeline as outlined in the Consent Decree. Sable expects to fill the ~540,000 barrels of crude oil storage capacity at LFC by the middle of June 2025 and subsequently recommence oil sales in July 2025.
Production Restart
-
On May 15, 2025, Sable initiated the flow of oil production from six wells on Platform Harmony of the SYU to LFC at a rate of ~6,000 barrels of oil per day.
-
Sable has been testing wells on Platform Harmony throughout May 2025 and the well tests have performed consistently stronger than they did at the time of shut-in on May 19, 2015 when the SYU produced approximately 45,000 barrels of oil equivalent per day.
-
Approximately 30% of the 32 producing wells at Platform Harmony have been tested as of May 18, 2025 with the remaining Platform Harmony wells projected to be tested over the course of the next several days.
-
Sable expects to initiate production from the additional 44 wells on Platform Heritage and the additional 26 wells on Platform Hondo in July 2025 and August 2025, respectively.

Here’s the latest update from Google AI:
AI Overview
Houston-based Sable Offshore Corp. restarted oil production and sales at the Santa Ynez Unit off Santa Barbara on March 29, 2026, producing over 1 million barrels and targeting ~50,000 barrels per day (bpd). The restart was triggered by a DOE directive under the Defense Production Act, following a 2015 spill. This action is causing intense legal battles with California state officials and environmental groups.
-
Production Status: Operations have resumed at Platform Heritage and Harmony, with plans for Hondo in June 2026.
-
Legal Conflict: Despite the federal directive, a Santa Barbara Superior Court has upheld a preliminary injunction (as of April 17, 2026) forbidding the pipeline operations.
-
Company Strategy: Sable, led by CEO Jim Flores, is moving oil through the pipelines despite state opposition, arguing the move ensures energy security.
-
Lawsuits: Sable is suing Santa Barbara County for over $100 million in damages for permit delays.
-
Production Details: As of April 20, 2026, over 40 wells were active, producing an average of ~750 bpd per well, with about 1 million barrels already produced.
