Reservior Engineering for Non-Reservoir Engineers

This five-day course is designed for professionals who work with, or rely on, analyses provided by reservoir engineers, or who otherwise need to understand and communicate with them on a technical or commercial basis. The course provides an understanding of the underlying value and limitations of the analyses provided by reservoir engineers, as well as a better understanding of the required data and assumptions involved in the practice of reservoir engineering. Participants will obtain an understanding of routine reservoir engineering calculations, the data required to perform these calculations, the primary tools and techniques used by reservoir engineers, and the information gained by the application of those techniques. The limitations of the extrapolation of the results to the decision making process will also be covered. Throughout the course, the impact of the data, assumptions and technical limitations are related to the economic impact they have on reservoir management.

Reservoir Engineering is a comprehensive, multidisciplinary evaluation of both producing and non-producing oil and gas fields. This may include reservoir characterization, reservoir engineering analysis, field development strategy, planning, production forecasting and reserves assessment, identification of uncertainties and risks and their mitigation and reservoir management and production optimization.

This course is a problem based learning (PBL) program and provides hands on experience.  Based on the data from two fields: Hatar Oil Field and Banjora Gas Field (fictitious), the course leads attendees to evaluate hydrocarbon volume in place, recovery factor, reserves, production forecasting and deliver development strategy and plan. The field examples emphasizes on the process and integration of various tasks, dealing with issues and their implications, and, above all, identification of subsurface uncertainties and associated business risks and their management.
