Well test information is critical for the prudent management of oil and gas reservoirs. Well testing is thus an integral part of the overall production and depletion strategy of a reservoir. The Alberta Energy Regulator (#AER) defines the minimum legal requirements for #welltesting which are considered essential for prudent reservoir management.
Forecasting stabilized gas well (#LNG) deliverability is important for tie-in economics, tubing string design, separation and facility design, and pipeline capacity contracts. The Alberta Energy Regulator (#AER) uses this information in reserves determinations, provincial forecasts of gas deliverability, and in processing applications for gas plants, pipelines, batteries, etc… Absolute open flow (#AOF) testing is thus a basic requirement for all gas (#LNG) wells. Surface deliverability data are acceptable only for a dry gas AOF <20 e3m3/d. Subsurface flowing pressure data must otherwise be acquired. Single point #welltests are compliant if the AOF is <300 e3m3/d, above which a multi-point test with LIT analysis must be conducted. In-line data (i.e. well on production) are acceptable. The Southeastern Alberta Shallow Gas System is exempt.
