Tullow Oil PLC and its Orinduick license partners are assessing the commercial viability of two offshore Guyana discoveries after lab results determined that the oil recovered is heavy crude with a high sulfur content. Jethro-1 and Joe-1 proved two different oil plays in the basin in August and September. The Jethro-1 well discovered 55 m of net pay in high-quality sandstone in the Lower Tertiary and Joe-1 encountered 16 m of net pay, opening a new play type in the Upper Tertiary. Both wells were drilled within budget, with measure while drilling logging tool and conventional wireline. Tullow said it remains confident in the potential across multiple prospects in both the Cretaceous and Tertiary throughout the Orinduik and Kanuku blocks.

The Carapa well, targeting the Cretaceous play in shallow water on Repsol’s Kanuku license just south of Orinduik, is currently drilling. Started at the end of October, results are expected before yearend.

The partners have sought a third-party consultant with heavy oil development expertise to answer technical queries and provide an initial assessment of several potential development drilling and production scenarios.

While results are being evaluated, the company is in the planning stages of a 2020 drilling campaign in pursuit of additional discoveries. Drilling will be determined by the partners in the coming months.

Tullow Guyana BV operates Orinduick with 60%. Partners are Total E&P Guyana BV, 25%, and Eco, 15%.
