„Stop pumping immediately upon observing deviation. Monitor and record the pressure decay to stability. Allow sufficient time to confirm that a stable pressure has been obtained. [...]
If formation breakdown occurs, pumping should be stopped, but the well should be kept shut-in and the pressure decay curve should be recorded. Fracture closure is indicated by stabilization of the pressure decay curve to a constant pressure value.”

„Chart Recorder shows stable test pressure for at least 10 minutes without visible leaks. The final stable pressure is at least equal to the required original test value. See Figure 14 for a pressure testing chart example. Stable test pressure is defined as a straight line on the chart recorder with no visible drop over the test duration.”
