TechTips

Did you know that Mini-Frac’ or Diagnostic Fracture Injection Tests (DFIT) can “Double For Initial Tests” in Alberta if subsurface pressure recorders are installed long enough. Formation leak-off data can be extrapolated to a p* acceptable for AER Initial

TechTips

Did you know that Alberta gas wells with deliverability over 300 e3m3/d require multi-rate or isochronal flow tests? Moreover, but little known, is that: if you didn’t do a multi-rate test, but did do a pressure build-up test, and

TechTips

Did you know there are several alternate or unconventional welltesting methods for achieving AER Initial Pressure requirements? Perforation inflow or injection tests, fracture injection or fall-off, and formation leak-off tests are some examples. Just a little known TechTip…

TechTips

Did you know Pressure Transient Analysis (PTA) can extrapolate a reservoir pressure (p*) to satisfy AER Initial Pressure requirements? You don’t have to conform with the “2 kPa Rule.” Engineering can move your completion operations along faster and more

TechTips

Did you know that AER Annual well testing requirements can often be satisfied from surface? Acoustic Well Sounders (AWS) are common in oil fields, and surface pressure recorders are acceptable in dry gas pools. Just a little TechTip hint…

TechTips

With regards to AER Initial Pressure requirements, did you know that subsurface pressure recorder data can be submitted without the extrapolated pressure (p*) from Pressure Transient Analysis (PTA), if data meet the 2 kPa Rule? Economic strategy if completion

D40.6: Compliance to Minimum Requirements

Regulatory requirements are those rules that an operator has a legal obligation to meet and against which the #AER may take enforcement action in cases of non-compliance. The AER issues weekly Initial and Annual Outstanding requirements. Extensions to deadlines

D40.5: Acceptable Test Standards

The manner in which #welltests are conducted and reported is always critical to the value of data obtained. Directive 40 (D40) defines the #AER quality standards required for well tests to fulfill survey requirements. Annual

D40.4: Clarification of Minimum Requirements

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
