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.


Production-data analysis (PDA) is a well-known method of investigating field performance. Nevertheless, its application in a giant brownfield can be difficult. Analysis can be very complex and time-consuming because of the large quantity of data and data heterogeneity and reliability, especially if the data are gathered through different monitoring systems and technologies.

Considering this, a systematic integrated work flow has been developed that focuses on brownfields where water injection has played a key role in oil production.
