ExxonMobil increases Stabroek resource estimate after 10th discovery

  • More than 5 billion recoverable boe discovered in less than four years
  • Reinforces potential for at least five floating storage, production and offloading vessels producing more than 750 000 barrels of oil per day by 2025
  • Pluma-1 well represents 10th discovery

The resource estimate, up from the previous estimate of more than 4 billion oil-equivalent barrels, is a result of further evaluation of previous discoveries and includes a new discovery at the Pluma-1 well.

“The discovery of a resource base of more than 5 billion boe in less than four years is a testament of our technical expertise and rigorous evaluation and pursuit of high-potential, high-risk opportunities in this frontier area,” said Neil Chapman, ExxonMobil senior vice president. “We will continue to apply what we’ve learned to identify additional exploration prospects and potential future discoveries that will deliver significant value to Guyanese people, our partners and shareholders.”

The Pluma-1 well encountered approximately 121 ft (37 m) of high-quality hydrocarbon-bearing sandstone reservoir. Pluma-1 reached a depth of 16 447 feet (5013 m) in 3340 ft (1018 m) of water. The Noble Tom Madden drillship began drilling on Nov. 1. The well is located approximately 17 miles (27 km) south of the Turbot-1 well. The Noble Tom Madden will next drill the Tilapia-1 prospect located 3.4 miles (5.5 km) west of the Longtail-1 well.

“Together with the government and people of Guyana, we are continuing to grow the value of the Stabroek Block for Guyana, our partners and ExxonMobil with successful exploration investments,” said Steve Greenlee, president of ExxonMobil Exploration Company. “Our ongoing work will evaluate development options in the southeastern portion of the block, potentially combining Pluma with prior Turbot and Longtail discoveries into a major new development area.”

The Liza Phase 1 development is expected to begin producing up to 120 000 bpd by early 2020, utilizing the Liza Destiny floating storage, production and offloading vessel (FPSO). As previously announced, Liza Phase 2 is expected to start up by mid-2022. Pending government and regulatory approvals, Liza Phase 2 project sanction is expected in early 2019 and will use a second FPSO designed to produce up to 220 000 bpd. Sanctioning of a third development, Payara, is also expected in 2019 with start up as early as 2023.

The Stabroek Block is 6.6 million acres (26 800 km2). ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45% interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds 30% interest and CNOOC Nexen Petroleum Guyana Limited holds 25% interest.
