Surface Seismic in a Mature Field – What is the Value of Surface Seismic Acquisition Parameters?

P297 Surface Seismic in a Mature Field – What is the Value of Surface Seismic Acquisition Parameters? P.M. van Baaren* (WesternGeco) H. Al-Ansi (Qatar Petroleum) & A.B. Thomson (Qatar Petroleum) SUMMARY This paper describes a case study where a structured approach was taken to determine optimal surface seismic parameters in Qatar Petroleum’s Dukhan field the largest onshore oilfield in Qatar with over 700 wells drilled into the structure. Several vintages of 3D seismic exist over the field – all from the early 1990’s. In 2003 an extensive seismic feasibility study was performed followed in 2006 by a combined borehole and
