Chapter 9. Well Deliverability

9.1. Introduction

Chapters 2, 3, 4, and 5 described well inflow performance of oil, two-phase, and gas reservoirs, for vertical, inclined, and complex well architectures. The inflow performance relationship (IPR) was presented in a traditional and standardized manner, with the bottomhole flowing pressure on the ordinate of a graph and the corresponding production rate on the abscissa. This type of depiction gives a comprehensive picture of what the reservoir can deliver into the well at a specific time. Except for the case of steady-state flow, the well IPR would change with time. This would be both under infinite-acting conditions and under pseudosteady-state conditions where the reservoir pressure declines with ...
