Abstract
In recent years, new drilling technologies have changed the traditional well profile to increase field productivity. The majority of new wells now being drilled have one or more horizontal legs in order to maximize the drilled hole interface with the rock formation, thereby increasing production from a single wellhead. New techniques to manage and service these wells have also emerged, however, re-entry into open hole or uncontrolled multilateral junctions can be difficult.
A new coil tubing tool or lateral entry guidance system has been developed to help locate and steer into these multiple completions. The tool uses a unique methodology for use with standard coil tubing to gain access into lateral legs. No special electrical conduits are required to operate the tool and tool function is automatic when downhole. A precise series of pressures and flow rates from a surface pump are the only requirement to operate the tool. The tool can deliver most stimulation fluids directly via the coiled tubing or piggyback other coil tubing tools.
