ExxonMobil increases estimate for Stabroek block to 4 bn barrels




ExxonMobil has increased its estimate of the discovered recoverable resources for the Stabroek Block offshore Guyana. To more than 4 billion oil-equivalent barrels and has advanced its evaluation to support a third phase of development and consideration of two additional phases.
The increase follows completion of testing at the Liza-5 appraisal well, a discovery at Ranger, incorporation of the eighth discovery, Longtail, into the Turbot area evaluation and completion of the Pacora discovery evaluation. The previous recoverable resource estimate was 3.2 billion oil-equivalent barrels.
Guyana’s first development, Liza Phase 1, will use a floating production, storage and offloading (FPSO) vessel to produce 120,000 barrels of oil per day, starting by early 2020. Liza Phase 2, which is targeted for sanctioning by the end of this year, will use an FPSO vessel designed to produce up to 220,000 barrels of oil per day and is expected to be producing by mid-2022.
The Liza-5 well successfully tested the northern portion of the Liza field and, along with the giant Payara field, will support a third phase of development in Guyana. The Payara development will target sanctioning in 2019 and will use an FPSO vessel designed to produce approximately 180,000 barrels of oil per day, as early as 2023.
The Longtail well established the Turbot-Longtail area as a potential development hub for recovery of more than 500 million oil-equivalent barrels. Additional prospects to be drilled in this area could increase this estimate.
