Abstract

Summary

Nowadays reservoir models become more and more sophisticated in terms of methods and approaches used. The ultimate objective of a reservoir model is to obtain as accurate as possible estimation of hydrocarbon in place volumes, to capture impacting heterogeneities, and to be as much predictive as possible for dynamic units. This is achieved by a construction of 3D geological model populated with petrophysical properties. Rock-typing is one of the approaches allowing to populate a geologically coherent 3D model with petrophysical data.

The present rock-typing feasibility study has been performed on a clastic gas field, which reservoirs were formed in two distinct depositional environments - fluvial and tidal dominated. The study has included construction of static rock-types model per each interval, followed by the permeability modeling. The main complexity of the study was the poor quality of dataset (old exploration wells, with limited number and quality of acquired logs). Therefore, the challenge was the ability to correctly define and propagate rock-types to all well vintages.

This paper presents the main outcomes of the rock-typing feasibility study, as well as its added value for the reservoir characterization.
