What are the AER stability requirements for a GRD.pas file?
The AER requires that the Electronic Recorders used during the .GRD test must be left On Bottom for a minimum of 2 hours and the pressure must not exceed +/- 2.5 kPa per hour. If the well has been shut-in for longer than 14 days then a 10 to 15 min On Bottom stop is acceptable and it is not required to meet the pressure stability requirements to pass as an "Initial Test".
