• Choke Management / Sand Productions
• Well Construction Optimizations
• Process Efficiencies (Big Scales)
Operational Challenges
Tecpetrol Unconventional Resources
• No SEC special rules for unconventional estimation and classification
• Volumetric Method required a multidisciplinary approach
• No industry standards currently exist for analysis and interpretation
in shale gas/oil reservoirs.
• Methods and models are still evolving and adapting.
• It is best practice to check volumetric against by back calculating the RE
(recovery efficiency) and evaluate its reasonability.
• In general, the combination of a well defined volumetric method and
performance with decline curve analysis type Arps modified can
sufficient to support reserves reporting before SEC
