A pilot full‐azimuth survey for a fractured carbonate reservoir, in North West Raudhatain Area, Kuwait

3D Seismic Survey Design, Second edition

“…A very special testing method is to acquire a pilot survey, which can be used to learn about new acquisition techniques and/or to determine the most suitable survey parameters in an area where more 3D surveys are likely (Shabrawi et al, 2005;Dutta et al, 2009;Rached et al, 2009). If there is serious doubt about the acquisition parameters to be used, the pilot survey must be overdesigned, allowing decimation tests.…”

“…In one implementation, they use what can be called "fat" receiver lines, in which each receiver line consists of up to four sublines, each subline being densely sampled. The single geophones are staggered in adjacent sublines such that in the inline direction, the effective geophone sampling is equal to the basic sampling interval or to the adequate sampling interval (Dutta et al, 2009;Rached et al, 2009). The fat receiver lines can simulate shot arrays in the crossline direction, thus allowing the use of larger shot intervals equal to the effective width of the fat receiver lines.…”
