ABSTRACT
Determination of
Effective Proppant Distribution After Fracturing Using Multiple Gamma Ray
Tracers
A significant
application of multiple tracers is their use in tracing different proppant
concentration stages and/or types of proppant to determine their effective
wellbore distribution at the fracture entrance. Extensive heterogeneous
formations with large fracture intervals containing multiple perforated
intervals or hydraulic fracture treatments that utilize the limited entry
technique provide one of the best opportunities for using multiple tracers to
evaluate proppant distribution.
