Simon Petroleum Technology was contracted by Sagasco Resources to forward model a suite of synthetic CDP gathers for the Crayfish Formation in the Crayfish-A 1 well, using synthetic shear velocities generated from the client's log interpretation model. Since the formation was water-bearing, the contract also required modelling of a gas column from the top of the Crayfish sand unit at 1594 metres KB down to 1746 metres KB, followed by a comparison of the Amplitude Versus Offset (AVO) response of the two models. To achieve these aims, data from 11 km of seismic line SO94-119 and 7.5 km of line HO93-102 (the latter line passing through the well and crossing the former at almost right angles) were processed for AVO, then inverted to acoustic impedance.
