Pattern-Review Technique Maximizes Hydrocarbon Recovery in Complex Brownfield

Large, complex, faulted structures often pose substantial challenges in maximizing hydrocarbon recovery. The work presented in this paper has used what the authors call a “pattern-review” technique in a brownfield containing more than 500 well penetrations in southeast Asia. For the first time in field history, pattern reviews have been used extensively as a tool to understand reservoir connectivity and dynamic fluid movements across the field. An integrated effort involving different data sources and disciplines has provided fresh insights into the reservoirs that would have otherwise been difficult in heterolithic stacked reservoirs.

Introduction

The Champion field is 40 km offshore Brunei Darussalam in water depths of approximately 40 m.
