Diagnostic Fracture Injection Testing (DFIT)

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...

Sample eREPORT Level 2 (simplified)

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...
