Abstract

The purpose of the present study is aimed to carry out Hydraulic Flow Unit (HFU) modeling for a clastic oil reservoir of Linch Pay, Linch Field, Cambay Basin. Linch pays of Older Cambay Shale of Early Eocene sequence are discrete sand bodies embedded in monotonous shale unit. Lithofacies and distribution pattern of clastic unit depicts eight subpays from LUI to LU-VIII from top to bottom.This study involves rock type classification based on routine and special core analysis data, statistical methods such as histograms, probability plot and cluster analysis. Finally seven HFU's constituting the reservoir were identified based on calculations of Reservoir Quality Index (RQI) and Flow Zone Index (FZI). In addition to that three major rock groups were also identified based on core description.This study will help in understanding the heterogenity of Linch pay and also assist in reliable estimation of the permeability in uncored wells, generation of initial water saturation profiles and consequently reliable reservoir simulation studies
