ExxonMobil advances next phase of Guyana development with Longtail

SPRING, Texas – ExxonMobil has made a final investment decision for the Longtail development offshore Guyana following required government and regulatory approvals. Longtail, the eighth development located 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 condensate-rich reservoirs with significant potential for future gas exports. Subject to future investment decisions, market demand and the development of necessary infrastructure, gas from Longtail could be transported to shore by pipeline. The project will utilize a floating production storage and offloading (FPSO) vessel designed to process 1.2 billion standard cubic feet per day of gas and produce up to 250,000 barrels of condensate per day (bpd).

The US$12.5 billion project is expected to include approximately 45 subsea production and injection wells.
