WRAP UPFinal Words

• Dunvegan is a prolific oil and liquids-rich gas resource play

• Variations in geology overwhelmed by completions technique

• Other factors affecting production rates

Reservoir heterogeneity

Optimal well spacing and production acceleration

Quality of drill targets in later development stages

• Completions trends

Completed length

Frac stages

Fluid pumped per stage

Slickwater usage = rate increase especially in gas

WCSB Deepest Penetration by Section
