However, none of them give the characteristics of pressure buildup test for such wells. In recent years, the impact of fracture (artificially-induced or natural fracture) permeability loss on production performance of shale gas wells has drawn much attention. Some researchers (e.g. Ozkan et al...
Assuming negligible pressure loss in the surface injection line, determine the minimum required gas injection pressure using a kinetic energy index safety factor of 1.2 for the design gas injection rate. 2. Plot profiles of the pressure, velocity, gas density, and kinetic energy index along the ...
(b) Outlet pressure stability test with pressures set to 1, 5, and 10 kPa, by turning the control knob to the 1st, 14th, and 20th positions, respectively, following the calibrated results in (a). The pressure was measured over 5 days to check the stability of the outlet pressure ...
