Perforation Inflow Diagnostic Tests
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 are limited. Subsequent completion, stimulation, clean-up, and testing operations often seriously affect our ability to acquire quality pressure build-up data for analysis. Using subsurface pressure recorders will also satisfy ERCB Initial Pressure Gas (IP...

Characterizing Reservoir Properties using Diagnostic Fracture Injection Testing (DFIT) was presented at a recent Society of Petroleum Engineers (SPE) luncheon. A great talk – and a great reservoir diagnostic test – as our example Level 2 eREPORT illustrates: DFIT2 Mini-frac’ Fall-off. But…here in Alberta…as per ERCB Bulletin 2010-38 surface (or acoustic well sounder) data are no longer acceptable for Initial Pressure Gas or Initial Pressure Oil requirements. For compliance with Initial Pressure requirements the...

The second sample eREPORT I’d like to point out is PTA2 Theoretical 4pt AOF – Pressure Transient Analysis Level 2. Our Level 2 eREPORT is simplified in terms of write-up: only a summary of analytical results and conclusions. Level 2 is great for internal use and ERCB compliance where detailed discussion is not required. Analyses and data are still included, but with primary bookmarks only. Our example also illustrates taking advantage of the theoretical Initial Deliverability Gas submission when the transient AOF >300 e3m3/d...

We now have a variety of sample eREPORTS available for perusal. The first one I’d like to draw your attention to is titled PTA1 Comprehensive: Pressure Transient Analysis level 1 comprehensive. This is the traditional, legacy style, turnkey eREPORT for reservoir engineering, reserve auditors, and data rooms – with robust analytics, petrophysical, logs, completion reports, deviation, fluid properties, reserves, and Board certificates, all in one place. The write-up is thoroughly inclusive: objectives, conclusions, background, data...
