Longtail marks a new phase of development on the Stabroek block, targeting non associated gas and condensate-rich reservoirs. 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 Longtail project is expected to include approximately 45 subsea production and injection wells.
«Guyana is home to one of the world’s most prolific energy developments, and Longtail represents the next phase in realizing the full potential of its resources», said ExxonMobil Upstream Company President Dan Ammann. «By developing these gas and condensate resources, we’re unlocking new value for Guyana while delivering advantaged energy to meet growing global demand».
Longtail builds on ExxonMobil’s long-term commitment to Guyana. Today, approximately 6,000 Guyanese support Stabroek block operations. Since 2015, ExxonMobil Guyana and its contractors have spent more than US$3.9 billion with Guyanese suppliers.
ExxonMobil is safely producing approximately 900,000 barrels of oil per day (bpd) from four projects in the Stabroek block. With the expected startup of the fifth project, Uaru, in the fourth quarter, production is expected to exceed 1 million bpd.
Construction is also progressing on Whiptail and Hammerhead, the sixth and seventh approved projects. Whiptail is anticipated to begin production in 2027, with Hammerhead expected to follow in 2029.
ExxonMobil affiliate ExxonMobil Guyana Limited is the Longtail operator and holds a 45% interest in the Stabroek block. Hess Guyana Exploration Ltd. holds 30% interest, and CNOOC Petroleum Guyana Limited holds 25% interest.
In April, Saipem won 150 million USD contract for ExxonMobil's Longtail project in Guyana.
