Abstract

Summary

For more than 50 years, dual-porosity type models have been used for modeling fluid flow in naturally fractured reservoirs (NFRs). However, despite the ubiquity and importance of fractured and faulted hydrocarbon reservoirs, and the acknowledged complexity of modeling hydrocarbon flow in such reservoirs, few authors have challenged the capability of the dual-porosity type models to simulate the behavior of NFRs. There are conditions under which dual-porosity type models may be applied.

Here, we use our new solution for the pressure transient behavior of continuous connected and discretely fractured reservoirs containing arbitrarily placed fractures of different lengths, densities, and orientations that addresses many of the shortcomings of the dual-porosity type approach. Unlike the dual-porosity approach, which contains only two parameters to describe the interaction between the fracture and matrix media, it is challenging to apply such geologically-realistic models to history matching due to the number of variable parameters. We present a new methodology for pressure transient test design and analysis using our solutions to gauge the sensitivity of a pressure transient test to realistic geological parameters and to provide a geologically consistent “most-likely” model under uncertainty.
