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 this translates to one survey per productive section. For gas pools, one survey per four productive sections is required.” Referencing ‘one survey (#welltest) per X productive sections’ is confusing for large gas (#LNG) plays which have not been fully drilled up. In these low density, or low well count pools, surveying 25 % of the drilled wells may actually leave some ‘productive’ sections un-tested.
