There are many useful applications for surface pressure data instruments, besides those already described. Optimization or surveillance purposes for determining timing for the running or pulling of subsurface pressure
It is common practice in pumping oil wells to use acoustic well sounder instruments (#AWS) to obtain reservoir pressure buildup data without pulling rods and pump. With this method
Electronic surface pressure gauges have several fundamental advantages over acoustic well sounder instruments (#AWS). First, the sampling rate is significantly higher, whereas acoustic instrument sampling rates are controlled by
Valid interference #welltest results can be obtained from water injection wells, flowing oil wells, and pumping oil wells. For this example, pressure buildup data were obtained on a pumping
It appears only logical that surface pressure data could prove useful for interference #welltesting in high permeability gas zones. Valid results have been derived from both producing wells and
Pre-frac’ #welltests have proven successful using closed chamber methods. Surface pressures are recorded during perforation. The surface pressure buildup is proportional to gas influx into the closed chamber (wellbore).
