This paper presents a case history of the pilot 3D seismic processing of the ultra high-density and full wide-azimuth 3D seismic survey across the Dukhan field for Qatar Petroleum (QP). The acquisition of the survey commenced in early in 2009 and took 2 years to complete. The pilot processing was carried out in parallel over a small 85 sq km area as a test to parameterize the 860 sq km production processing. The pilot test was completed in early in 2011. The VSP and uphole data processing and analysis has been initiated. The production surface seismic processing is expected to be completed by mid-2012. This paper focuses on the pilot test processing.

This paper presents acquisition of a large, ultra high density and full wide azimuth 3D seismic survey across the Dukhan field for Qatar Petroleum (QP) and in particular the acquisition of the Transition Zone (TZ) and sabkha elements of the project. This survey represents a step change in seismic data acquisition by full wide azimuth and very dense spatial sampling complemented by uphole and simultaneous 3D Vertical Seismic Profile (VSP) recording. It is expected that this survey will set an industry standard for seismic acquisition leading to improved field redevelopment. While the 3D seismic data can always be reprocessed in the future, re-acquisition of the entire Dukhan field area may be difficult to justify. Therefore one of the key principles of the survey design was to ensure that the source and receiver effort was fully specified, so that it represented a "no regrets" case for the future. The survey commenced in Q1 2009 and until January 2010 the acquisition was fully a vibroseis operation. From January to December 2010, TZ acquisition operated concurrently with the vibroseis operation. This was followed by the final sabkha acquisition in January-February 2011. Data processing has commenced and targeted to complete by mid-2012.

Oil and gas E&P are faced with challenge of achieving seismic data acquisition quality control (QC) in more extreme environments. In this direction, oil and gas companies must manage more projects from supervisors' desktops using rapidly multiplying online capabilities and remote-access databases. In the hands of modern practitioners, the purpose of the modern QC process is to determine and then verify whether the field process of acquiring and transmitting seismic data meets or exceeds the expectations of the customers. Regularized, repeatable procedures can overcome the previous dissimilar project practices that resulted in unreliable data. A consistent level of QC personnel training conquers poor field practices and improves report generation. JagSeis Seismic Acquisition Management & Quality Control by Jaguar Exploration provides a complete suite of interactive modules, including the ability to send, receive, and archive critical QC data safely and securely via the Internet.
