What specific data is required from a pressure transient analysis test to determine the skin factor near the wellbore?

To determine the skin factor near the wellbore from a pressure transient analysis test, several specific data points are required. First, the initial reservoir pressure (Pi) before the test begins must be accurately known. This represents the undisturbed pressure of the reservoir before any production or injection occurs. Second, the wellbore pressure (Pwf) as a function of time during the test is essential. This pressure is continuously measured by a downhole pressure ga....
