Abstract: A tool, a piping assembly, a system using the tool and piping assembly, and a method using such tool and piping assembly for fracking and production of hydrocarbons from an underground hydrocarbon formation is disclosed. The tool is conveyed downhole using continuous tubing, and by application of fluid pressure supplied to the tool configured in three distinct configurations—a first non-actuated configuration, a second actuated configuration, and a third emergency release/flushing configuration. The emergency release/flushing configuration may be actuated to initiate flushing of pressurized fluid in the region of the tool to flush sand and detritus and thereby prevent or overcome sanding-in or lodging of the tool within the wellbore. The tool, when used with the piping assembly as disclosed, reduces fracking times by allowing continuous deployment of the tool without having to activate and deactivate the tool at each fracking stage.
