The Well Analyzer with the pressure transient option can be used to obtain pressure buildup data. The operator programs the Well Analyzer to acquire data points while unattended. The rate may be specified in either shots per hour or shots per log cycle. Numerous diagnostic and analysis plots are available including casing pressure vs. time, liquid level vs. time, bottomhole pressure vs. time, log-log plot with derivative, Homer plot, MDH plot and radial flow type curves. Real time viewing of the plots ensures that the wells are returned to production as soon as the test objectives have been reached.
