Experience in performing MOGT-3D seismic jobs with Slip-Sweep Method

Authors: G.G. Gilaev, A.E. Manasyan (Samaraneftegaz JSC, RF, Samara), M.B. Scvortsov (Rosneft Oil Company OJSC, RF, Moscow), A.F. Ismagilov, V.S. Zhuzhel (SamaraNIPIneft LLC, RF, Samara), V.N. Kozhin, V.I. Efimov (Samaraneftegeofizika OJSC, RF, Samara)

Key words: eismic surveys, Slip-Sweep method, spread shooting, vibroseis source, performance rating.

The paper presents the experience in performing the MOGT-3D seismic and exploration jobs on an industrial scale using the Slip-Sweep method. It was illustrated that the application of this method exceeds the classical seismic study by the parameters like tine to perform the jobs, information content in the materials obtained in challenging seismic/geological and surface conditions. Slip-Sweep method was initially applied on a commercial (for 455 sq. km) and not a test mode at the Russian territory. Considering the fact that the performance of these jobs became possible in the conditions with highly-developed infrastructure, in the areas with high forest coverage, at the agricultural lands with numerous rivers and cross-country terrain the authors consider that the performance of these jobs based upon Sleep-Sweep method is perspective also for other Russian regions.
