Abstract:It has been widely demonstrated that frac stimulation efficiency and more importantly production, varies significantly between perforation clusters as well as between sleeve entries. Recent trends indicate that many operators are simultaneously increasing the number of perforation clusters or entries while decreasing frac-to-frac spacing. This is done with the expectation that it will lead to more productive wells overall. The purpose of this paper is to investigate some of the aspects that may limit this appr… Show more
“…Although the underlying mechanisms are still under investigation, closely spaced parallel hydraulic fractures have been observed in the few core-back experiments performed up to date. A recent study (Ugueto et al, 2019) that deployed optical fiber in a horizontal well also observed that a "dual peak" signature commonly appeared at many perforation clusters in the poststimulation warm-back DTS measurements. Jeffrey et al (2009) also saw subparallel strands of hydraulic fracture in a mine-through experiment.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
