Hess Corporation has announced another oil discovery offshore Guyana at the Uaru well, and revealed an increase in the estimated gross discovered recoverable resources for the block to more than 8 billion barrels of oil equivalent, (up from the previous estimate of 6 billion barrels of oil equivalent).

This oil discovery is the 16th on the Stabroek Block – its recoverable resources are now estimated to be over 8 billion barrels of oil equivalent. This includes 15 discoveries offshore Guyana through year-end 2019. The Uaru discovery is the first of 2020 and will be added to the resources estimate at a later date.

The well, drilled in 1,933 meters of water, is located approximately 10 miles northeast of the Liza Field – Uaru encountered approximately 29 metres of high quality oil-bearing sandstone reservoir. 

Oil production from Liza Phase 1 started on December 20, 2019 and “is currently ramping up” according to a statement by Hess. It is expected to reach its full production capacity of 120,000 gross barrels of oil per day in the coming months, utilising the Liza Destiny floating production storage and offloading vessel (FPSO).

The Liza Unity FPSO will be employed for the second phase of the Liza development and will have a production capacity of 220,000 gross barrels of oil per day. Liza Unity is under construction and expected to start production by mid 2022.

Elsewhere, (pending government approvals and project sanctioning), production from a third development at the Payara field, located north of the Liza discoveries, could start as early as 2023, reaching an estimated 220,000 gross barrels of oil per day.

Four drillships in Guyana continue to explore and appraise new resources as well as develop the resources within approved projects. A fifth drillship is expected to be deployed later this year. The Stabroek Block is 6.6 million acres. At least five FPSOs are expected to be producing more than 750,000 gross barrels of oil per day from the block by 2025.

CEO John Hess said: “Previous discoveries on the block including recent high quality finds at Tripletail and Mako underpin a significant increase in estimated gross discovered recoverable resources for current and future developments. We also continue to see multibillion barrels of additional exploration potential remaining.”

ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45 per cent interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds 30 per cent interest and CNOOC Petroleum Guyana Limited, a wholly-owned subsidiary of CNOOC Limited, holds 25 per cent interest.
