Field Results: Effect of Proppant Strength and Sieve Distribution Upon Well Productivity

Huckabee, P. et al.

This study compares the production of 452 frac treatments in 30 new wells completed by Shell in the Pinedale Anticline. In the Lower Lance and Mesaverde intervals, 20/40 CarboProp provided 60% higher production rates than a broadly sieved ISP. Decline curve analyses indicated effective fracture lengths were 32% longer for CarboProp. EconoProp similarly outperformed broadly sieved ISP in the Lower Lance, providing 60% greater effective fracture length. API spec ceramics consistently and significantly outperformed broadly sieved ceramics, and were the preferred economic choice in this field.
