Chapter 10. The Displacement of Oil and Gas

10.1 Introduction

This chapter includes a discussion of the fundamental concepts that influence the displacement of oil and gas both by internal displacement processes and by external flooding processes. It is meant to be an introduction to these topics and not an exhaustive treatise. The reader, if interested, is referred to other works that cover the material in this chapter.15 The reservoir engineer should be exposed to these concepts because they form the basis for understanding secondary and tertiary flooding techniques, discussed in the next chapter, as well as some primary recovery mechanisms.

10.2 Recovery Efficiency

The overall recovery efficiency E of any fluid displacement process is ...
