(f) You may not resume operations until you obtain a satisfactory pressure test. If the pressure declines more than 10 percent in a 30-minute test, or if there is another indication of a leak, you must submit to the District Manager for approval your proposed plans to re-cement, repair the casing or liner, or run additional casing/liner to provide a proper seal. Of course this happens after the old Renal is gone! I have a machine failing negative pressure tests (neg stabilize and once in a while neg flow) I found it needed new brushes, so I replaced those, have calibrated deaeration and flow pumps, changed hansen o rings, adjusted the flow pump, made sure testing was running at good conductivity and 37 .it is a kind of tester that use compression air to produce negative pressure by vacuum device to test the seal capability and processing technique of soft plastic packaging material. It has advantages of easy operation, novel design, convenient to observe test result, especially to detect some tiny pole leak.If the casing or liner top packer does not have the required integrity, there may be an additional leak path that could jeopardize the production process and even pose danger to the safety of the well.
