INTRODUCTION
HZ Drilling, Multi-Stage Hydraulic Fracturing:Today is the norm throughout the industryVery High Drilling & Completion costs In WCSB over 5600 HZ Wells Drilled
Over 4000 Wells for Gas and Liquid RichCost > 6 MM $$/wellEUR > 4 BcfeLow Commodity Prices Predicted
SUCCESS IS RESERVOIR SPECIFIC“ONE SIZE FITS ALL” IS NOT THE ANSWERFIELD ANALOGIES ARE DANGEREOUS

Motivation: WHY?
• Stimulated Reservoir Volume (SRV)
Mike Mayerhofer = “Godfather” of SRVBetween 2006 – 2010 many SPE papers, articles
SPE 163833 (February 4 – 6, 2013)“Change of heart” Authors distance themselves from SRVCONCLUDE: “Reservoir permeability is the main driver…..”

CONCLUSIONS
1. UNIQUE TYPE CURVE FOR HZ-MSF WELL PRODUCTION EXISTS
2. CONVENTIONAL APPROACH FOR PRODUCTION EVELUATION OF HZ-MSF COMPLETIONS WORKS
PSS Equation (Pi, km, A, s’, n)
3. IN-SITU km & Pi CONTROL AND DETERMINE HZ-MSF EUR
4. PID TESTING IS THE MOST ACCURATE PRE-FRAC TECHNIQUE Pi, km
5. DFIT TEST IS A GREAT TOOL FOR FRAC ENGINEERS ISIP, Breakdown, Closure, Tortuourosity
6. MAYERHOFER et al, PULLED THE PLUG ON “SRV”
