The Effects of Proppant Selection Upon Well Productivity – A Review of Over 650 Treatments in the Cardium Formation

Rightmire, C.M. et al.

For the most common treatment (60 tonnes of proppant placed with a gelled hydrocarbon fluid), wells treated with EconoProp provided 40% more gas than wells treated with sand. Ceramic proppant outperformed sand or RCS in 9 of 11 treatment designs, and average payback times ranged from 30 to 60 days. Increased fracture conductivity was also beneficial in Cardium oil wells when sand size and/or concentration was increased. Wells receiving 12/20 sand often achieved twice the oil rate of treatments with smaller sand sizes.
