Sable Offshore, a Texas-headquartered oil and gas company, is set to resume oil production at its third platform off the California coast next month, marking the latest step in the company’s phased effort to bring its offshore operations back online.
Sable claims to have progressed field operations at the Santa Ynez Unit (SYU), the Las Flores Canyon Midstream Processing Facility (LFC), and the Santa Ynez Pipeline System (SYPS) towards steady-state operations, after resuming oil production from the Heritage platform in early April 2026.
An average of approximately 47 wells at the Harmony and Heritage platforms were online in July 2026, producing around 721 gross barrels of oil a day per well. While the firm expects to bring all 77 production wells on these two platforms online during the third quarter of 2026, it anticipates the Hondo platform to come online in September 2026.
The company confirmed that the wireline campaign for perforation additions and producing well optimization at the Harmony platform started in August 2026. Sable elaborates that five completed perforation additions, each forecasted to produce an incremental 600 estimated gross barrels of oil per day, are expected to come online at Hondo along with the restart of the platform in September 2026.
In addition, four more perforation additions at the Hondo platform, projected to produce an incremental estimated 600 gross barrels of oil per day, are planned for completion and to be brought online in early Q4 2026.
The U.S. firm highlighted: “Due to the California regulatory environment, local refineries were not able to plan in advance for SYU first sales and ultimately were forced to displace various imported cargos in the second quarter. As a result, Sable incurred $18.5 million of non-recurring demurrage charges throughout the quarter, recognized in operational expenses.
“The sudden supply influx of Pacific Outer Continental Shelf (Pacific OCS) crude has forced refiners to temporarily limit throughput of Pacific OCS crude and charge quality deducts for sulfur content and other items.”
According to Sable, the Hondo platform is expected to produce lower sulfur content oil, which should bring field-wide sulfur content to normal levels upon planned restart in September 2026.
