One-page notes, tips, and hints to provide subject clarity.
AER 2 kPa Rule
Alberta’s 2 kPa Rule for shut-in durations <14 days allows for initial and annual tests to be submitted without analysis.
Popular Annual Testing methods include acoustic well sounder (AWS) for pumping oil wells and surface pressure build-up tests…
Popular Initial Testing alternatives include Perforation, Fracture Fall-off, and Formation Leak-off technologies.
What’s not specifically clear in Directive 40 is that Pressure Transient Analysis (PTA) is acceptable for estimating a p* for Initial Pressure Oil and Initial Pressure Gas conditions.
Multi-point Isochronal Tests in high deliverability gas wells help quantify turbulence factors for rate-dependent skin and tubing performance evaluations.
Mini-Frac’ DFIT Doubles for Initial Test… Mini-frac’ or Diagnostic Fracture Injection Tests (DFIT) help double your testing efficiency if pressure recorders are installed on bottom.
