Paper Number: SPE-141456-MS
... a hydrostatic pressure of 131 psi. The differential pressure that the plug is subjected to from the bottom or downstream side is -9097 psi (131 psi – 9228 psi). Positive Test The positive test is the customary test applied to a CP and sometimes a CFP. After the plug is set and gas in the casing has been...

... are also employed. While effective for larger leaks, these methods can produce nebulous results with smaller leaks and can be time consuming. The frequency spectrum a leak produces is a function of differential pressure, leak magnitude, and leak geometry. These properties determine whether the frequency...

... to the surface during the next valve open period. Over time period from [A-1] the plunger falls past the tubing collar recess and acoustic pulses are generated from the rapid release of the differential pressure across the plunger. This acoustic pulse, which is generated at the tubing collar recess, travels...
