Amberjack, which is jointly owned by Chevron, resumed operations Friday and is flowing at reduced capacity, a Shell spokesperson said. Mars is expected to be up by 4pm central time, according to people familiar with the matter.
Chevron has so far resumed production at its Jack/St. Malo, Tahiti and Big Foot platforms. Other shuttered assets include Shell’s Mars, Ursa and Olympus fields and Equinor ASA’s Titan platform, the companies said. Murphy Oil Corp. also shut some platforms, a spokesperson said.
If both pipelines return to service on the expected timeline, production losses will be minimal, according to Energy Aspects.
The shut-ins come at a time when global energy supplies are exceedingly tight. While US crude inventories have been cushioned by the government’s tapping of emergency oil reserves, stocks nevertheless remain below the five-year average. Supplies could tighten further, with the International Energy Agency forecasting that oil demand will accelerate this year.
Prices for Mars Blend crude, a regional sour crude benchmark, strengthened Thursday before easing Friday. At the same time, Gulf of Mexico dry-gas production fell about 10%, the most since January, according BloombergNEF estimates based on pipeline flows.
