Gas Injection in Gas Condensate Reservoirs

Course details

• One-third to one-half of the original oil-in-place may remain in a reservoir as it reaches abandonment due to its economic limit. The primary reasons are: heterogeneity of the reservoir, unfavorable fluid properties, and inefficient nature of the displacement process, oil price, and production cost considerations.
• The secondary reasons, however, are: inappropriate development, inefficient reservoir management practices, and escalating costs of remedial interventions/corrective measures and producing operations.
• The oil recovery is generally lower than expected due to some combination of the above reasons. Gaining a better understanding of the reservoir fundamentals and the important variables that influence the recovery process can enhance it.
• This overview course aims to provide such an understanding. It presents the subject material with a clear focus on:
• developing and producing the reservoir efficiently within its complexity constraints, harnessing energies available within the reservoir-aquifer-injection system, realizing technical benefits and application limitations of the various EOR methods, and selecting the optimum time window.
• This course covers the recovery improvement possibilities that present themselves at all stages in the reservoir life cycle. It thereby enables one to timely select the most beneficial method and set realistic expectations on production behavior changes and recovery improvement.
• The impacts of the selected method on personnel training, technology transfer, and facility modification are also covered. The material is presented in simple terms that would enable a participant to understand what works where, what fails when, and why. It is light on theoretical equations, but it scrutinizes these to comprehend importance of significant parameters. It utilizes case studies from projects around the world; their analyses and interpretations aid the participant in understanding of the material. Many illustrative problems, worked in the class by teams, are helpful in gaining a better grasp of the subject matter.
