oa Dukhan 3D: from Ultra High Density, Full Wide Azimuth Seismic Survey for the Future

This paper presents a case study on the logistics and acquisition of an ultra high density and full wide<br>azimuth 3D seismic survey across the Dukhan field in Qatar. This survey represents a step change in<br>seismic data acquisition with greatly enhanced data quality by full wide azimuth and very dense spatial<br>sampling. It is expected that this survey will set an industry standard for seismic acquisition leading to<br>improved field redevelopment.<br>The Dukhan field is a large oil field in Qatar established in 1941, it contains over 700 wells producing<br>from 4 major reservoirs. It has a rather complex history of production & development strategies;<br>starting with natural pressure depletion for more than 20 years, followed by power water injection<br>since 1989 and gas cap cycling since 1998. As other large mature Middle East oil fields, Dukhan also<br>witnessed large changes in technology over the last 60 years. In order to maximize the long term<br>economic recovery from the field, QP is committed to applying leading edge but fit for purpose<br>technologies. New, state of the art, 3D seismic data combined with updated reservoir models will<br>enable QP to continue the development of Dukhan field for many years to come.
