CGG completes survey over Abu Dhabi's Hail, Shuweihat fields
PARIS -- 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 Company (ADNOC).
Seismic operations were implemented to the highest QHSE standards to acquire the two-part survey, covering a total area of 1,200 km2 and lasting over 18 months. The first part involved acquisition of over 600 km2 of data for the Hail project located 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 500 km2 of data over an offshore and onshore area of 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 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 1,500 km2 shallow water seabed survey over Ghasha-Butini field to be acquired with the support of Seabed Geosolutions.
