Description:
PT 4 is a full-featured system for evaluating pressure transient well tests. Using a standard Windows user interface, it implements most classical and log-log type curve methods, as well as an advanced "Adjust and Compare" technique to interactively interpret test data. This version of PT also includes a new method for well test interpretation using acoustic well data (fluid levels and surface pressures).See following pages for screen displays of PT 4
