ExxonMobil Approves Guyana Longtail Development: Additional $12.5 Billion Investment, 2030 Start-Up, Up to 250,000 Barrels of Condensate a Day
ExxonMobil announced on November 12 that it has made a final investment decision for the Longtail development offshore Guyana, following required government and regulatory approvals, with an additional investment of about US$12.5 billion planned. Longtail, the eighth development in the southeastern portion of the Stabroek block, is expected to come online in 2030.
Longtail marks a new phase of development on the Stabroek block, targeting non-associated gas and condensate-rich reservoirs. The project will use a newly built floating production storage and offloading (FPSO) vessel designed to process 1.2 billion standard cubic feet of gas per day and produce up to 250,000 barrels of condensate per day, with approximately 45 subsea production and injection wells. Subject to future investment decisions, market demand, and the development of necessary infrastructure, gas from Longtail could be transported to shore by pipeline.
Four projects in the Stabroek block are already producing about 900,000 barrels of oil per day. ExxonMobil Guyana Limited operates the block with a 45% interest, Hess Guyana Exploration Ltd. holds 30%, and CNOOC Petroleum Guyana Limited holds 25%. Under earlier company disclosures, SBM Offshore is performing front-end engineering and design for the Longtail FPSO using its Fast4Ward hull program.
