The EXCITE system from Comitt Well Solutions is a patented downhole tool technology designed for restimulation and refracturing of existing oil and gas wells. The tool is deployed on either coiled tubing or conventional stick pipe and enables selective pinpoint injection of fluid and proppant into both existing and newly added perforations. Activated solely by pump rate and pressure, the EXCITE system allows for adaptive activation and deactivation of the tool, through-tool circulation, and reverse circulation without any need for mechanical manipulation of the work string. This unique feature in turn allows for debris cleanout and screenout mitigation to prevent stuck-tubing scenarios. The tool system has recently been field-trialed in previously completed shale wells in which both existing stages and newly added perforation clusters in between old stages were treated in a single run. During field trials, 170,000 lbm of sand were placed into a single cluster at pump rates up to 17 bbl/min.
