Jet and Inject Tool and Its Application for Directional Hydraulic Multi-Fracturing

P30 JET AND INJECT TOOL AND ITS APPLICATION FOR DIRECTIONAL HYDRAULIC MULTI- FRACTURING Abstract 1 The proposed apparatus for treating rock surrounding a wellbore comprises a hollow elongated housing having nozzles radially mounted therein which are projectable externally thereof. Each nozzle has a through passage communicating with the internal space of the housing to pass the flow of a fluid with an abrasive filler there through. The body of each nozzle also has auxiliary passages. The external end faces of the nozzles are shaped so as to press against the wall of the casing. In the course of operation nozzles
