Shell has begun production from Silvertip Phase 3, a two-well development supplying its US Gulf production facility, Perdido. Subsidiary Shell Offshore confirmed the start-up in an announcement dated 28 October 2026.
Using subsea facilities already in place, the development connects the Silvertip Frio reservoir to Perdido. Shell expects the wells to reach a combined peak output of up to 6,000 barrels of oil equivalent per day (boe/d). The company puts recoverable resources for this phase at an estimated 17 million boe. Both estimates represent the whole project before allocation to individual partners.
The resource estimate carries a 2P classification under the Society of Petroleum Engineers’ Resource Classification System. Shell operates the reservoir development with a 40% interest; Chevron holds 60%.
Located in the Alaminos Canyon area, the Perdido spar operates in water about 8,000 feet deep, roughly 200 miles south of the Texas city of Galveston. It receives production from three fields: Great White, Silvertip and Tobago.
Ownership of the Perdido Regional Host differs from that of the reservoir development. Operator Shell has 35%, while Chevron U.S.A. holds 37.5%, 3C Perdido Holdings has 26.5% and BP holds 1%.
