Chapter 12. Well Test Analysis: Type Curves

12.1 Introduction

In Chapter 11, well test analysis with straightline methods were presented. In that chapter, the difficulties associated with correctly identifying the time region over which straightline methods are applicable were discussed. In some cases, engineers analyzing the same well test data could identify different times for the start of the infinite-acting radial flow (IARF) regime, which is crucial to the application of straightline methods for calculation of well and reservoir properties. Well test analysis was improved tremendously by combined application of straightline methods and type curves on the same well test data. In this chapter, representative type curves, such as Ramey type ...
