Ras Al Khaimah 3D

Offshore the United Arab Emirates, the Ras Al Khaimah sub-basin offers a diversity of play types given that it sits between the Cretaceous carbonate platform of Abu Dhabi & Dubai and the fold and thrust belt of the Hajar mountains.

The main reservoirs fall into the Thamama Group, one of the most prolific in the region. This area is historically underexplored despite exploration and production efforts dating back to the late 1960s, which resulted in the discovery of the Saleh gas and condensate field which produced until 2016, and a light oil discovery called RAK B. The newly acquired data also reveals deep prospectivity as 3WD and 4WD closures in the Jurassic and Permian intervals with multi TCF potential.

The 2,200 sq.km Polarcus Triple Source 3D was designed to cover the entire width and breadth of the Emirate’s waters. The survey was acquired using an efficient XArrayTM configuration: 6 x 112.5m x 6,000m, resulting in an 18.75m cross-line sample interval to image the 30 degree dips found in the foreland fold and thrust belt. Source array shot interval was set to 12.5m to maintain high inline fold while allowing 5.4 seconds of clean data below the water bottom so that AVO sensitive targets at 1.0 to 4.0 seconds two-way time are outside of the blended zone.

An advanced time processing sequence was utilized on the data, which included merging-in the vintage 3D over the obstructed areas, including deblending, deghosting and Kirchhoff pre-stack time migration. Final PSTM deliverables are available now.
