Integrated Water-Injection Analysis Uses Salinity as Tracer in Giant Brownfield

When dealing with giant brownfields, a systematic approach is mandatory to succeed in identifying the main production mechanisms amid the geological and dynamic complexity of the reservoir. In this paper, an integrated work flow is proposed for brownfields where oil production is driven mainly by water injection. Produced-water salinity plays a key role, acting as a natural tracer and, thus, helping avoid additional costs for new data acquisition.

Introduction

Production-data analysis (PDA) is a well-known method of investigating field performance. Nevertheless, its application in a giant brownfield can be difficult.
