Allows for an Initial or Annual #welltest to be submitted without analysis (#PTA). Conventional static gradient surveys, with a 10–15 minute
on-bottom stop, are acceptable. Sometimes the extended gauge won’t pass the 2
kPa Rule, but the gradient will,

We would like to extend our sympathy and understanding to all of our fellow Calgarians during this unprecedented natural disaster. This catastrophe has obviously impacted everybody in our community, and the economic ripples will be felt across Canada. My parents
Perforation Inflow Diagnostic (PID) tests satisfy ERCB Initial Pressure requirements. These simplified tests, now in common usage, provide an economical alternative to traditional methods. Basically the well is perforated under-balanced, and the subsequent closed chamber pressure build-up is monitored with
Perforation, fracture fall-off, and formation leak-off tests satisfy ERCB Initial Pressure requirements. These simplified tests, now in common usage, provide an economical alternative to traditional methods. There are several different scenarios, depending on your completion operation logistics. One method is
Mini-frac’ or Diagnostic Fracture Injection Tests (DFIT) help double your testing efficiency if subsurface pressures are recorded. First, a successful DFIT helps estimate hydraulic fracture closure pressure and reservoir flow properties – valuable information for stimulation design. Second, the resulting
What’s not specifically clear in G40 is that Pressure Transient Analysis (PTA) is acceptable for estimating Initial Pressure Oil and Initial Pressure Gas conditions.
Misconception #1: all tests have to pass the 2 kPa Rule. Not
We are coming out the other side of closing our office and moving home. Most technical issues have been resolved – but the server is still for sale (cheap!). Now that we have time to breath I can start uploading
Three separate inquiries in one week makes for an easy blog topic!
So, your Initial Pressure Gas (IP Gas) or Initial Pressure Oil (IP Oil) submissions have been accepted by the ERCB – but the UWI still shows up on
Perforation Inflow Diagnostic (PID) Tests are an excellent, and cost effective, method for obtaining a quality estimation of initial reservoir pressure conditions. As the name implies, these tests are conducted during or immediately after perforating – so reservoir pressure transients
