Better wellbore coverage, proppant delivery

摘要

Anew sequenced fracturing technique mat uses a composite blend of degradable particles and fibers was implemented in 2014 by more than 30 operators in 11 major North American basins to successfully deliver stimulation fluids to understimulated or inaccessible well sections. Better contribution to production from fractures also is attained by incorporating fibers in die fracturing fluids to improve proppant transport and placement. In multiple studies using different applications of the treatment, results showed the methodology can improve production rates, increase reservoir contact and reduce completion times and operational costs.
