This course is crucial for reservoir and petroleum engineers, as well as geologists and petrophysicists involved in reservoir surveillance, field development, and enhanced oil recovery (EOR) projects. It provides an overview of the petrophysical knowledge required to understand and monitor EOR processes. The course addresses key logging milestones prior to injection, with a focus on ensuring well integrity through cement bond and corrosion log evaluation, as well as strategies for selecting appropriate monitoring logs. During injection, logging techniques used to ensure injection efficiency—such as Production Logging Tools (PLT)—will be discussed. In addition, the evaluation and interpretation of monitoring logs, including Thermal Decay Time (TDT) and porosity logs, will be covered both at the well level and between wells. Case studies on logging surveillance for EOR projects will be presented and discussed. The course will be conducted through group discussions, practical exercises, and the use of specialized software.
