An Integrated Multi-disciplinary Approach to Enhance Confidence in Development of a Tight Heterogeneous Reservoir

Abstract

This paper covers the integrated approach performed in one of the major oil fields in off-shore Abu Dhabi to increase the confidence level in this tight heterogeneous reservoir development.This paper outlines the challenges that were faced along with the history of this field and the different approaches made by the development team to overcome them. The paper discusses the steps that the team went through in a period of ten weeks in order to come up in the end with an optimized subsurface & completion strategy plan. It shows how the reservoir with three main reservoir subzones is divided into 43 layers based on the sequence stratigraphy approach. It also discusses how the new infill well locations were optimized and designed with a fit-for-purpose completion strategy. The paper will present the final outcomes of this review, the opportunities identified and the latest results obtained from the more confident post optimized development plan.
