Reservoir Appraisal and Development

Program Objectives

In this 5-day course, exploration and development views will be covered with the aim of gaining a thorough understanding of various reserves levels and their equivalence in both systems, in terms of proved, proved plus probable, and proved plus probable plus possible. Methodologies of different countries will be covered. Participants will work in mixed teams, usually from different technical backgrounds. Initial work involves re-evaluation of the structure and incorporation of the discovery well data into the seismic database. The second phase involves a full review of the reservoir (sand body type and continuity, porosity distribution, net/gross calculation and permeability), the recalculation of in-place volumes and the building of a reservoir model. Thirdly, the characteristics of the reservoir fluids and aquifer are examined, with the teams assessing different development plans, reserves and production profiles and considering the best economic solution. A final exam is administered at the conclusion of the class.
