Reservoir Engineering

Basic Reservoir Engineering for Non-Petroleum Engineers

Introduction

The objective of reservoir engineering is to optimize hydrocarbon recovery. This course will introduce basic reservoir engineering concepts and methods to enable the cross-disciplinary exchange of ideas and experience. The course will help participants to understand crucial questions such as, how much oil and gas is there (accumulation)? How much can be recovered (reserves)? How fast can it be recovered (rate)? The participants will also work practical problems to ensure a thorough understanding of the principles and procedures.

This comprehensive course describes the main aspects of reservoir engineering. Reservoir engineering has been defined as (the art of developing and producing oil and gas fluids in such a manner as to obtain a high economic recovery). The course begins with a broad overview showing how reservoir engineers assess the value of the reservoir from volumetric, fluids, flow, and investment perspectives. Next is an elaboration on how much oil can be recovered from various natural reservoir drive mechanisms. Next decline curves are used to explain how investors forecast well or reservoir production. Then we explore how key well and reservoir flow properties are quantified through the formation and well testing. Finally, flow simulation modeling is explained as a way to rigorously forecast primary, secondary, and even tertiary or enhanced oil production
