The US oil & gas company ConocoPhillips has signed a long-term sales and purchase agreement (SPA) for the offtake of 4 Mt/year of LNG from the Port Arthur LNG Phase 2 project, currently under development by Sempra Infrastructure, a subsidiary of Sempra, in Jefferson County, Texas (United States). The agreement covers a 20-year term, with deliveries on a free-on-board (FOB) basis.
The Port Arthur LNG project will include two liquefaction trains with a combined capacity of 13.5 Mt/year, along with two LNG storage tanks and related infrastructure. Commercial operations are expected to begin in 2027 for Train 1 and 2028 for Train 2.
In July 2022, ConocoPhillips signed a separate 20-year SPA for 5 Mt/year of LNG from Phase 1 of the project and acquired a 30% equity stake in that phase. While a final investment decision (FID) is still pending for Phase 2, ConocoPhillips’ involvement will be limited to LNG offtake, with no equity participation.
In August 2025, Japanese utility JERA also signed a 20-year SPA for 1.5 Mt/year of LNG from Phase 2. Earlier, in May 2025, Saudi energy group Aramco signed a memorandum of understanding (MoU) to purchase 5 Mt/year of LNG over 20 years from the Phase 2 expansion.
