Integrated Waterflood

Book now button

Course overview

Waterflood is the most widely deployed incremental recovery process in the oil industry. Although it is now firmly established that the process can add significant incremental volumes to field recovery, the process is very rarely optimised. Historically, waterflood has been seen as primarily the domain of the reservoir engineer but, given that problems can become manifest across virtually all disciplines, a fully optimised development needs the successful input of all of those disciplines. This course has therefore been developed to train staff on all aspects of waterflood. It therefore facilitates a fully integrated approach to field optimisation.

Learning objectives

Section learnings (see Course outline below) are cemented through the use of exercises. In addition there is a field case history to further highlight topics discussed during the course. This looks at a real field at 4 stages of its lifecycle. Following an initial depletion period, the following phases are addressed:

  • Pilot
  • Implementation
  • Remediation
  • Optimisation (inc infill)

In teams, course participants will identify problems associated with the waterflood implementation and develop remediation plans.
