Abstract

Summary

A new approach for modelling geobodies in clastic reservoirs has been developed using a random walk approach. It allows generating very realistic images of geology in the 3D space, with the preservation of sediment continuity along the sedimentation profile. The method is based on the simulation of sediment transportation path through the computation of trajectories. These ones are then dressed with parametric surfaces for generating the geobodies in the gridded reservoir model. The workflow includes: 1) the computation of the transportation flow for generating stream lines; 2) the simulation of sediment trajectories guided by the stream lines; 3) the dressing of the trajectories according to the location in the 3D space. The method enables an easy conditioning to well static hard data, but also an unusual conditioning on various dynamic and seismic information and data.
