Abstract
A system is provided that is conducive to multi-stage stimulation in a near-continuous fashion. That is, unlike conventional stimulation systems, embodiments herein may operate without the requirement of traditional plug-setting, perforating and fracturing interventions on a zone by zone basis for a cemented completion. Rather, the system is outfitted with frac sleeves that may be shifted open to expose the bore to the formation while simultaneously achieving a seal through a ball drop technique. Once more, this manner of operation is rendered practical by the sleeve being of a passable configuration such that cementing of the casing is not impeded.
