A data monitoring system includes a data monitoring tool incorporated into a work string proximate a bottom hole assembly. The data monitoring tool detects at least one wellbore condition and at least one force experienced by the data monitoring tool.

Real-time tension, compression and torque data monitoring system

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.

Release tool for coiled tubing

A cyclic check valve is provided for a coiled tubing string which enables reverse circulating for a specific period when a specific combination of pumping condition and oil conditions are favorable. The check valve may be activated to prevent reverse flow up through the valve and into the coiled tubing in the event of a failure of the coiled tubing at surface. The valve may be de-activated to allow reverse circulating. The check valve includes a flapper valve which may be de-activated by shiftable sleeve locked in place by a J-slot assembly. The check valve may be cycled from the activated to de-activated position and verified by a change in pressure drop through the tool.
