Summary: | A perforation blocking sleeve is provided for use in well restimulation, the perforation blocking sleeve having a first anchoring device and one or more expandable members secured to an outer surface of the perforation blocking sleeve. The first anchoring device may be used to secure the perforation blocking sleeve over a perforation cluster within a perforated well casing. The perforation blocking sleeve defines a flow channel and may be remotely and individually uncoupled from a running tool. The perforation blocking sleeve flow channel is sized such that the running tool and a running tool driver are retractable through the flow channel of the perforation blocking sleeve. In one or more embodiments, the perforation blocking sleeve contains an organic polymeric material which expands on contact with a production fluid or an exogenous fluid introduced into the well. |
