The Canje Block is currently operated by an ExxonMobil subsidiary, Esso Exploration & Production Guyana Limited (35 per cent), with Total (35 per cent), JHI (17.5 per cent), and Mid-Atlantic Oil & Gas (12.5 per cent) as partners.

Westmount holds an indirect interest in the Canje Block as a result of its circa 7.7 per cent interest in the issued share capital of JHI Associates. Following a 2018 farm-out to Total, JHI is carried for the drilling of the Jabillo-1 well and is funded for the drilling of additional wells.

In an update on Monday, Westmount Energy noted the announcement by the Maritime Administration Department, Guyana that the Stena Carron drillship would restart exploration drilling operations at the Jabillo-1 wellsite on 5 June 2021.

Jabillo-1 is the second of three exploration wells scheduled for drilling on the Canje block in 2021. Jabillo-1 is a circa 1,000 MMbbl oil prospect targeting a Late Cretaceous, Liza-age equivalent, basin floor fan.

As previously reported, ExxonMobil started getting ready to drill the Jabillo-1 well following the completion of the Bulletwood-1 earlier this year.
