Seismic survey navigates sensitive shallow-water UAE region

Offshore staff

PARIS – CGG, supported by its Seabed Geosolutions joint venture with Fugro, has completed a 3D seismic survey offshore/onshore Abu Dhabi.

Abu Dhabi National Oil Co. (ADNOC) commissioned the survey over the Hail and Shuweihat oil and gas fields. The project scope included data processing and reservoir characterization.

CGG’s survey covered a total area of 1,200 sq km (463 sq mi) and was conducted in two phases over 18 months. The first part involved acquiring more than 600 sq km (231 sq mi) of data for the Hail project located offshore and in the shallow waters of the Merawah natural reserve, a marine UNESCO World Heritage site.

This was followed by acquisition of more than 500 sq km (193 sq mi) of data over an offshore and onshore area of the Shuweihat field. Due to the location on the site of various government interests, the program here called for careful planning and coordination, CGG said.

Processing and reservoir characterization are under way at CGG’s Abu Dhabi center. One goal is to use understanding of the geological targets and integration of well information to provide reliable images over a large geological sequence for identifying key faults and mapping of stratigraphic traps.

Recently, ADNOC also contracted CGG to acquire a 1,500-sq km (579-sq mi) shallow-water seabed survey over the Ghasha-Butini field, again supported by Seabed Geosolutions.
