The Transient Response of Formations to Flow in a Well: Transient Pressure Well Testing

  • Arnold Watson
Chapter

Abstract

Quantifying the ability of a geological formation to allow fluid to flow through it is an essential part of geothermal engineering, but fortunately it is equally important to groundwater and petroleum engineering and has been under development since the 1930s. Although it is a fluid mechanics-based topic, it could equally well be described as signal processing. This chapter introduces the fundamentals and then presents the relevant basic equations, their most often-used solution and the principle of superposition which allows the design of well tests. Ideal conditions for testing are defined and the historical development of methods of dealing with real effects such as skin and wellbore storage in single-phase flows is described. The chapter ends by describing the approach to analysing the flow in formations containing two-phase fluid and interference testing.
