Abstract
About 70% of the oil produced today comes from mature fields, which focuses the interest of the industry on these fields, especially when the recovery factor is low (under 30%).
To increase the recovery factor, techniques as water injection can be implemented which also helps to mitigate the environment impact, transforming the water produced from an unwanted to a resource.
Having permanent control over the reservoir when is going through a secondary recovery, requires optimize the processes of displacement and recovery. The monitoring has the power to set the behavior of operational parameters for the optimization of the injection-production operations and to diagnose potential problems, which allow having a specific and a general vision of the process.
The continous monitoring process should be considered from the planning of injection-production system. The technology that provides constant monitoring is the DTS-Fiber Optics System, which allows the generation in real-time of production profiles and come across with more frequently the injection distribution. With the proper interpretation of these logs the following can be achieved: the injection rate optimization, injectivity leak detection, leak control in wells, cross-flow detection, the contribution of each zone in a stratified reservoir, and detection of the water breakthrough in the producer well.
This paper contains a conceptual level study, which presents the working principle, applications worldwide, Benchmarking, benefits, advantages, best technical setup and the correct procedure for implementing the DTS-Fiber Optic system for both a producer and an injector well. Additionally an economic evaluation which compares the DTS-Fiber optic System with conventional monitoring systems currently implemented to generate injection and production profiles in the Yariguí-Cantagallo field in Colombia are presented.
Finally, the main findings, conclusions and recommendations obtained in this study are shown.
