About Tullow in Guyana

View Guyana Map

Guyana has become an industry hotspot following giant oil discoveries in the Starbroek block. Tullow has interests in two neighbouring licences offshore Guyana with a 60% operated interest in the Orinduik block and a 37.5% non-operated interest in the Kanuku block.

Tullow’s position in Guyana dates back to 2008, when the Group farmed into the then named Georgetown licence, operated by Repsol. In 2013, Repsol re-secured the newly defined Kanuku block, and Tullow secured a 30% interest. In early 2018, Tullow agreed to increase its equity share in the Kanuku licence from 30% to 37.5% in a farm-in deal with Repsol.   

In early 2016, Tullow increased is Guyana position after being awarded a 60% operated interest in the Orinduik licence which is a 1,776 square kilometre offshore block.

exploration & appraisal

Acquisition of new 3D seismic across Tullow’s Guyana licences in 2017 highlighted a number of potential prospects across both the Kanuku and Orinduik licences. In 2019, Tullow was ready to commence its exploration programme and started a three-well programme to test three different play types – the Lower Tertiary, the Upper Tertiary and the Cretaceous. 

In August 2019, Tullow announced its first oil discovery in Guyana, with the Jethro-1 well on the Orinduik Block. The well encountered 55m of net oil pay in high quality oil bearing sandstone reservoir in the Lower Tertiary play. This discovery was followed in September by the Joe-1 discovery in the Upper Tertiary play which is a new play opener for the overall Guyana basin. This second discovery on the Orinduik Block successfully de-risks the petroleum system of the Western area of the Orinduik Block, where a significant number of Tertiary and Cretaceous age prospects have been identified. The Cretaceous Carapa prospect in the non-operated Kanuku licence is the final well in the 2019 programme, and is expected to commence operations at the end of September with a result in the fourth quarter of 2019.
