This course offers a software-independent view on the process of reservoir model design and simulation model-building, addresses the underlying reasons why some models disappoint and offers solutions that support the building of more efficient, fit-for-purpose models.

Considerable time is dedicated to reservoir model and simulation exercises in many companies but the results often disappoint: the time taken to build models is often too long, the models too detailed and cumbersome and the final model is ultimately not fit-for-purpose. This course examines the reasons why and offers remedies to fix these problems.

Duration and Logistics

Classroom version: 4 days; a mix of classroom lectures (60%), case studies (20%) and exercises (20%). The manual will be provided in digital format and participants will be required to bring a laptop or tablet computer to follow the lectures and exercises.

Reservoir Engineering for Geoscientists (G024)

Tutor(s)

Mark Cook: Associate Reservoir Engineer at TRACS International Consultancy and Independent Engineer at Delta-T Energy Consultancy.

Overview

The course examines reservoir engineering processes, techniques and terminology, particularly those that interface with geoscience activities. The material is structured around the three-part process of building a reservoir model: (1) building a static model to identify the main flow units, (2) developing a dynamic model to predict fluid flow in the reservoir, and (3) implementing a life-of-field reservoir management plan to maximize economic recovery. Numerous examples illustrate the use of subsurface data and the techniques employed during the construction of a reservoir model. The focus is on the principles rather than the detailed work of the reservoir engineer; the use of complex mathematics is avoided.
