PT 4.0 for Windows

The Echometer analysis is a specialized technique for analyzing Echometer (tm) data, where surface pressure and fluid level are measured instead of bottomhole pressure. The PT software allows both the surface pressure and fluid level to be directly estimated from theoretical curves and compared directly to the measured data. Nonlinear estimation and regression techniques are used to find the best match of the theoretical curves to the data. The estimated parameters are then used to determine the physical well and reservoir parameters.
