ExxonMobil is back drilling at its second wildcat on the Canje block offshore Guyana after partially completing the well earlier this year.

The US supermajor was set to recommence drilling at the Jabillo-1 exploration well on 5 June, London-listed company Westmount Energy said on Monday, citing information from Guyana’s Maritime Administration Department.

Westmount holds an indirect interest in the block thought its 7.7% interest in JHI Associates, which has a 17.5% stake in Canje.

Block operator ExxonMobil is once again using the drillship Stena Carron on the well. The Stena Drilling-owned unit had moved off the well earlier this to head to the US supermajor’s prolific adjacent Stabroek block to finish drilling the Koebi-1 well.

“Previously published information indicates that Jabillo-1 is a circa 1 billion barrel oil prospect targeting a Late Cretaceous, Liza-age equivalent, basin floor fan,” Westmount said, referring to JHI’s website.

Liza is the name of the first oil discovery made by ExxonMobil and its partners on the adjacent Stabroek block k to finish drilling the Koebi-1 well.

Jabillo-1 is the second of three exploration wells ExxonMobil plans to drill on the Canje block this year, with the final
well, Sapote-1, set to be the last in the campaign.

The first well, Bulletwood-1, failed to find commercial hydrocarbons. Before drilling it was estimated Bulletwood could hold 500 million barrels of oil.

Situated between 180 and 300 kilometres off Guyana’s coast, the Canje block covers 6021 square kilometres and water depths are between 1700 and 3000 metres.

ExxonMobil operates the block with a 35% interest, French giant Total holds 35%, JHI has a 17.5% stake and Mid-Atlantic Oil & Gas holds the remaining 12.5% equity.
