Tullow Oil makes maiden oil discovery in Orinduik block offshore Guyana


Orinduik block oil discovery : Tullow Oil and partners have made an oil discovery in the Orinduik block in the Suriname Guyana basin through the drilling of the Jethro-1 exploration well, as per the latest oil and gas industry news.

The Jethro-1 well, which was drilled by the Stena Forth drillship to a total depth of 4,400m in nearly 1,350m of water depth, intersected 55m of net oil pay. Tullow Oil said that the maiden Orinduik block oil discovery supports a recoverable oil resource estimate which surpasses its pre-drill forecast.

The Orinduik block, which spans 1800 sq km, is located 170km off the coast of Guyana. The offshore Guyanese block is contained in 70-1,400m water depths.

Tullow Oil claimed that the Jethro-1 discovery in the Orinduik block is made up of high-quality oil-bearing sandstone reservoirs of Lower Tertiary age.

The company plans to evaluate the data from the Jethro discovery and define appropriate appraisal activity.

The UK-based oil and gas company said that the first discovery on the Orinduik license significantly de-risks other Tertiary age prospects on the block. Included in these is the shallower Upper Tertiary Joe prospect, which will be spudded later this month after the conclusion of operations at the Jethro-1 exploration well.

Tullow Oil, through its subsidiary Tullow Guyana is the operator of the Orinduik block with a stake of 60%. The company is partnered by Total E&P Guyana (25%) and Eco (Atlantic) Guyana, which holds the remaining 15% stake in the offshore Guyanese block.

Paul McDade – CEO of Tullow Oil, commenting on the Orinduik block oil discovery, said: “This substantial and high value oil discovery in Guyana is an outcome of the significant technical and commercial focus which has underpinned the reset of our exploration portfolio. It is an excellent start to our drilling campaign in the highly prolific Guyana oil province.

“We look forward to drilling both the Joe and Carapa prospects in our 2019 drilling campaign and the material follow-up exploration potential in both the Orinduik and Kanuku licences.”
