Alberta’s 2 kPa Rule

For shut-in durations <14 days allows for an Initial or Annual #welltest to be submitted without analysis (#PTA). Note the #AER computer check has built-in leniency and will accept pressure changes <±2.5 kPa/h. Static gradient and ‘single-shot’ AWS files are checked over the last 2.0 h. Extended subsurface, surface, and acoustic well sounder (AWS) transient gauge data files are checked over the final 6.0 h. These rules apply to either oil or gas (#LNG) wells.
