Directive 040: Pressure and Deliverability Testing Oil and Gas Wells
Purpose of this Directive
This directive sets out requirements for pressure and deliverability tests, drill stem tests, fluid sampling and analysis, and coalbed methane and shale gas control well tests. It is intended to serve as a handbook for anyone testing oil and gas wells, regardless of their experience. However, test quality will improve if licensees/operators use properly trained personnel, and take care in designing, conducting, analyzing, and reporting their tests.
Note that the well testing requirements defined in this directive are minimum requirements, and the AER may require testing that exceeds these requirements. In addition, for specific geological zones within a defined area, the AER may adapt subsurface directive requirements through a subsurface order to better suit the resource development practices being used.
