A flapper valve preferably used in injection application in deep subterranean locations has an actuating sleeve with a seat to accept an object. A j-slot connects the actuation sleeve movement to the housing so that with an object on the seat and an applied pressure cycle the sleeve moves the flapper to the open position. The plug is dissolved and the injection begins. The plug can have an opening so as to allow continuous injection flow as the flapper is operated. Closing the flapper involves a second object on the same seat and a pressure cycle so that a spring can push the sleeve away from the flapper to allow a torsion spring on the flapper to close it.

A new approach is disclosed for measuring the pressure of tight gas reservoirs, using information obtain from continuous injection prior to hydraulic fracture stimulation. The technique can be obtained utilizing either bottom-hole or surface pressure gauges and properly instrumented surface injection pumps. The analysis is completed by plotting injection and rate data in a specialized form from terms arranged in Darcy's radial flow equation to obtain a curve or trend. The key component to proper application of this technique is to obtain both baseline and one or more calibration data sets.
