Abstract

Predrilling prediction of pore-pressure (PP) from seismic velocity has significant impacts on drilling of new wells. Model based post-stack seismic inversion has been carried out along an 8km seismic line passing across three wells. A velocity model has been developed for time to depth conversion of the inverted results by integrating all geological and velocity information for precise PP prediction. The inversion derived density and velocity models are used for mapping of overburden stress (SV) and PP along the 2D seismic line using Eaton
