First, a successful test helps estimate hydraulic fracture closure pressure and reservoir flow properties—valuable information for stimulation programs.
Time to plan for our #AER Annual Pressure Requirements.
Surface pressure recorders are fine for an annual #welltest — the caveat for gas (#LNG)
wells being that there cannot be a liquid level above the top perforation. Measuring

Time to plan for our #AER Annual Pressure Requirements. D40, section 4.5.7, states that “…the minimum number of pressure surveys should equal about 25 % of a pool’s producing well count. Based on quarter section spacing for oil pools
