Modelling of Fluvial Deposits and Their Transient Well Test Responses

P621 MODELLING OF FLUVIAL DEPOSITS AND THEIR TRANSIENT WELL TEST RESPONSES Abstract 1 The hydrocarbon bearing sandstones of fluvial reservoirs are deposited by rivers. Here we present a method of modelling point bar deposits by modelling the last stage of the meandering river path before abandonment. The point bars are inserted inside the bend of the path. After abandonment of the river path the channel is gradually filled with heterolithic sediments. These sediments form a baffle to flow through the deposited channel belt. The effective permeability contrast on the well test pressure transient between the point bar sediments and the
