Back in 2019, Westwood Global Energy Group put the resource estimate for ExxonMobil’s Tilapia-1 find in Guyana’s offshore Stabroek Block at 300 million barrels.
But new estimates by S&P Global Platts puts the estimate significantly higher.
S&P listed Tilapia-1 as holding between 1 billion and 1.5 billion barrels of recoverable oil-equivalent resources.

In 2019, Tilapia was paired with Yellowtail as the biggest high-impact oil discoveries for that year. S&P puts Yellowtail’s resource count as being between 500 million and 1 billion barrels. Westwood had also estimated Yellowtail to hold 300 million barrels.
Norway’s Rystad Energy had ranked the Tilapia find as being the third biggest conventional discovery for the first quarter of 2019. Cyprus’ Glaucus and South Africa’s Brulpadda were ranked number 1 and 2 respectively.
Tilapia-1 encountered approximately 305 feet (93 metres) of high-quality oil-bearing sandstone reservoir and was drilled to a depth of 18,786 feet (5,726 metres) in 5,850 feet (1,783 metres) of water.
