In gas wells (#LNG) involve sequences of alternating flow and shut-in periods. Inflow rates are incremented for each point. In Alberta the #AER requires an isochronal test when the transient AOF >300 e3m3/d, mainly for sour gas blowout considerations. If you didn’t acquire the data you can apply to the Board for a ‘Single Point AOF-PAS File Authorization’ (SGPTAU) special submission code. Otherwise, if there is a flow & build-up #welltest, we can analyze it (#PTA) and submit a theoretical AOF.
