Sterling Reaches TD at Cladhan Appraisal
Sterling Resources announced that appraisal drilling in the Cladhan well 210/30a-4y has outlined the extent of the overall Cladhan play within the license.
"Although the over-pressured nature of the reservoir suggests there may be remaining prospectivity up-dip from the current Central Channel well, this would likely need to be the subject of a future drilling campaign," stated the company. "This well and the previous 210/30a-4z deep well in the fan area have not impacted on the established Cladhan discovery. However, the results start to limit the upside potential on the license as a whole, and suggest that the Cladhan field is likely confined to the Northern Channel belt area and an area up-dip of the deep fan well."
The 210/30a-4y well was drilled as a sidetrack into the Central Channel prospect which lies to the south of the current Cladhan discovery. The well encountered two Upper Jurassic reservoir sand sequences with a gross true vertical thickness of 191 feet (58 meters) and a net of 40 feet (12 meters) TVT. Log pressure data indicates the sands are water wet.
The consortium plans to carry out an infield survey and a pipeline survey to determine how to best develop the Cladhan discovery. The Cladhan field is located on Blocks 210/29a and 210/30a in a water depth of 1,634 feet (498 meters). Serving as operator of the field is Sterling Resources, holding a 39.9% interest; EnCore holds 16.6%; Wintershall holds 33.5%; and Dyas holds the remaining 10%.SubseaIQ provides focused, in-depth coverage of offshore field development activities around the world, with daily updates on hundreds of offshore fields and facilities.
