Two more oil discoveries; more than 30 discoveries in Stabroek block since 2015
IRVING, Texas – ExxonMobil today announced two discoveries at the Sailfin-1 and Yarrow-1 wells in the Stabroek block offshore Guyana, adding to its extensive portfolio of development opportunities.
ExxonMobil has made more than 30 discoveries on the block since 2015, and it has ramped up offshore development and production at a pace that far exceeds the industry average.
“Our unrivalled exploration success and accelerated pace of development in Guyana are a testament to our people, decades of experience, technology capabilities and steadfast focus on optimizing all aspects of operations,” said Liam Mallon, president of ExxonMobil Upstream Company.
“We are committed to responsibly and safely developing this world-class resource to help meet global demand for secure, reliable and lower-emission energy. Our investments through the pandemic have allowed us to increase supply at this critical time, while creating value for the people of Guyana, our partners and shareholders.”
The Sailfin-1 well encountered approximately 312 feet (95 meters) of hydrocarbon-bearing sandstone and was drilled in 4,616 feet (1,407 meters) of water. The Yarrow-1 well encountered approximately 75 feet (23 meters) of hydrocarbon-bearing sandstone and was drilled in 3,560 feet (1,085 meters) of water. Both wells were drilled by the Stena Carron drillship.
ExxonMobil’s first two sanctioned offshore Guyana projects, Liza Phase 1 and Liza Phase 2, achieved an average of nearly 360,000 barrels of oil per day in the third quarter.
A third project, Payara, is expected to start-up by the end of 2023, and a fourth project, Yellowtail, is expected to start-up in 2025. ExxonMobil is currently pursuing environmental authorization for a fifth project, Uaru. By the end of the decade, ExxonMobil expects Guyana’s oil production capacity to be more than one million barrels a day.
Guyana’s Stabroek block is 6.6 million acres (26,800 square kilometers). ExxonMobil affiliate Esso Exploration and Production Guyana Limited is the operator and holds 45% interest in the block.
