Abstract

A bottom hole assembly for use with fracturing or fracing a wellbore using coiled tubing is described having a first packing element and a second packing element on a mandrel. The bottom hole assembly may be run into the wellbore such that the packing elements straddle the zone to be fraced. Also described is a timing mechanism to prevent the closing of dump ports before the bottom hole assembly may be flushed of the sand. A release tool is described that allows an operator to apply combination of force for a given amount of time to the coiled tubing to dislodge a bottom hole assembly without completely releasing the bottom hole assembly. Also disclosed is a collar locator capable of being utilized in a fracing process. Methods of using the above-described components are also disclosed.
