CGG, with the support of its Seabed Geosolutions joint venture with Fugro, has completed the acquisition of a 3D seismic survey over the Hail and Shuweihat oil and gas fields in the Emirate of Abu Dhabi, one of the world’s most environmentally sensitive areas.
The survey is part of an integrated project, including data processing and reservoir characterization, awarded to CGG by the Abu Dhabi National Oil Co. (ADNOC).
Seismic operations were implemented to the highest QHSE standards to acquire the two-part survey, covering a total area of 1200sq km and lasting over 18 months.
The first part involved acquisition of over 600sq km of data for the Hail project offshore and in the shallow waters of the Merawah natural reserve, which has a very rich biodiversity and is a marine UNESCO World Heritage site. It was immediately followed by the acquisition of over 500sq km of data over an offshore and onshore area of the Shuweihat field, which, due to its location on the site of various government projects and interests of the Emirate of Abu Dhabi, called for careful planning and coordination.
Processing of the high-quality data collected during the survey is being conducted in conjunction with reservoir characterization in CGG’s Abu Dhabi center. A good understanding of the geological targets and integration of well information at the outset of processing was key to providing reliable images over a large geological sequence for the extraction of key faults and mapping of stratigraphic traps.
ADNOC’s satisfaction with the acquisition component of the Hail-Shuweihat survey also played a part in its recent award to CGG of a contract for a 1500sq km shallow water seabed survey over the Ghasha-Butini field to be acquired with the support of Seabed Geosolutions.
Jean-Georges Malcor, CEO, CGG, said: “CGG is proud to be a key player in the high level of seismic activity currently ongoing in Abu Dhabi, as part of ADNOC’s plans to implement their extensive mid- and long-term field development projects. The choice of CGG for this integrated project indicates the strength of our shallow water and seabed solutions and our ability to successfully deliver complex programs, combining acquisition and subsurface expertise. We are particularly pleased that ADNOC wishes to benefit from our acquisition experience in environmentally sensitive areas to support its commitment to protecting the Emirate’s natural environment.”
