BENCHMARKING RESOURCE PLAYS Implications for Exploitation and Development
JULY 11, 2011
AGENDA ! Introduc)on: ! What is a Resource Play? ! Bench Marking Process ! Western Canada Resource Plays (overview) ! Montney: Sunrise, Glacier, Dawson ! Cardium: Rat Cr. vs Carrot Cr.
! Summary ! Conclusions
WHAT IS A RESOURCE PLAY?
“A 'play' is a family of pools and/or prospects that share a common history of hydrocarbon genera8on, migra8on, reservoir development and trap configura8on. A RESOURCE PLAY is a special category of play which implies the use, or poten?al use, of advanced drilling and/or comple?on technology to make it economic. Although specific wells may be excep8ons, generally speaking a RESOURCE PLAY is deemed to be historically uneconomic on a regional basis without the use of advanced technology.” Ed Fogg, Canadian Discovery Ltd.

MONTNEY: PROPPANT AND STAGE TRENDS
MONTNEY Longer Lengths / More Stages / Shorter Frac Intervals
Comple)on Costs declining over )me Produc)on/Stage decreases with increased stages
More Proppant does not equal more produc)on
Cased Hole Comple)ons appear to have lower costs, beJer produc)on rates and lower opera)onal failures
CARDIUM Carrot Creek vs Rat Creek
CARDIUM Carrot Creek vs Rat Creek
CARROT CREEK: 8.2 % Opera)onal Failure
RAT CREEK: 10.2 % Opera)onal Failure
CARDIUM: Carrot Creek vs Rat Creek
CARROT CREEK: 33% of Opera)onal Failures NOT related to Downhole (mechanical) Problems
RAT CREEK: 65% of Opera)onal Failures NOT related to Downhole (mechanical) Problems
CARDIUM: Carrot Creek vs Rat Creek

CRITERIA FOR EVALUATING RESOURCE PLAYS
GEOLOGY MATTERS Stress Analysis is a KEY criteria for evalua)on Resource Plays
CARDIUM Rat Cr. vs Carrot Cr.
Reservoir characteriza)on using surface microseismic monitoring Peter M. Duncan1 and Leo Eisner1 GEOPHYSICS,VOL. 75, NO. 5 (SEPTEMBER-‐OCTOBER 2010); P. 75A139–75A146
MICROSEISMIC IS THE ONLY WAY TO KNOW WHERE THE FRACS ARE
Case History: Horizontal Gas & Water RECON
THE ONLY WAY TO KNOW WHICH FRACS ARE EFFECTIVE IS TO USE FLOWBACK ANALYSIS
