WebJan 31, 2024 · Prediction of gas well deliverability is important for reservoir management. Conventional flow after flow, isochronal or modified isochronal tests are common methods for calculation of well deliverability. Single-point test using Vogel-type dimensionless inflow performance relationships (IPR) was also proposed to overcome the need for multi-point … Several different deliverability test methods have been developed to collect the data for use with the basic deliverability models. These tests can be grouped into three basic categories: 1. Tests that use all stabilized data 2. Tests that use a combination of stabilized and transient data 3. Tests that use all transient data … See more There are two basic relations currently in use to analyze deliverability test data. An empirical relationship was proposed by Rawlins and … See more Rawlins and Schellhardt1 presented the basic deliverability test method that uses all stabilized data.
