Abstract

Delineation of reservoir lateral continuity for flow zones in wells using cluster analysis: Case of West Baram Delta, offshore-Sarawak

Highlights

Reservoir property modeling is often used to determine lateral extent and continuity in targeted multiple wells for implementation of any enhanced oil recovery (EOR) methods
(Ringrose and Bentley, 2015) extent and distribution. These zones are mainly delineated through reservoir property modeling and simulation (Ringrose and Bentley, 2015) approach, but requires large of volume data by introduction of representative elementary volume (REV) (Bear and Bachmat, 2012) to develop dynamic version of geological flow zones
The analysis indicates an abundant porosity supportive characteristic ascribed to occurrence coarse and medium sub-rounded, rounded and well-rounded grains within studied lithofacies including the fine grained lithofacies introduced by occurrence of coastal to coastalfluviomarine sand which have been deposited in a northwestwards prograding delta since the Middle Miocene (Tan et al, 1999) during depositional regime

Summary

Introduction

Reservoir property modeling is often used to determine lateral extent and continuity in targeted multiple wells for implementation of any enhanced oil recovery (EOR) methods. As emphasis to maximize oil recovery from mature fields (Latief et al, 2012) around the world prompt renewed interest (Henares et al, 2014) to understand the distribution of fluid flow characteristic (porosity and permeability) in wells, since it is associated with changes in vertical and horizontal properties that occurred due to difference in depositional environments. These differences affect spatial and temporal distribution in porosity-permeability that determines reservoir extent and continuity between. Literature reveals that there are substantial heterogeneity within approximately 7000 feet thick stacked reservoir unit sequence of shallow marine sands of cycle V and VI (Rahman et al, 2014; Johnson et al, 1989)
