US-based oil and gas firm Exxon Mobil and its partners have made a new oil discovery at Snoek well on the Stabroek Block offshore Guyana.

The partners encountered more than 82ft of high-quality, oil-bearing sandstone reservoirs at Snoek well, which is located in the southern portion of the Stabroek Block, approximately 9km to the southeast of the 2015 Liza-1 discovery.

Drilling at the Snoek well started in February and targeted similar aged reservoirs as encountered in previous discoveries at Liza and Payara, the company said.

The well has been drilled to a total depth of 16,978ft using Stena Carron drillship.

ExxonMobil Exploration Company president Steve Greenlee said: “The latest discovery at Snoek demonstrates the continued success we have achieved in this technically complex play, which is just part of the significant exploration province offshore Guyana.”

Exxon’s affiliate Esso Exploration and Production Guyana operates the Stabroek Block with 45% interest while other partners include Hess Guyana Exploration with 30% interest and CNOOC Nexen Petroleum Guyana with 25% stake.

Greenlee added: “As we continue to evaluate the full potential of the broader Stabroek Block, we are also taking the necessary steps to ensure the safe, cost-efficient and responsible development of this world-class resource, which can provide long-term, sustainable benefits to the people of Guyana.”

With the completion of drilling at Snoek well, the Stena Carron drillship has now been moved to drill the Liza-4 well in the Liza area.

In January 2017, ExxonMobil and its partners have made oil discovery at Payara-1 well in the Stabroek Block. The well had encountered more than 95ft of high-quality, oil-bearing sandstone reservoirs.
