The LatchRite® junction construction system provides a high-strength TAML Level 4 junction with sand control and full gauge access to the lateral and lower mainbore. It utilizes an industry-proven, patented protected multilateral washover operation and achieves hydraulic integrity using cement. The LatchRite system can also be used to construct a TAML Level 2 junction that eliminates the disadvantages of conventional milling.
Applicable to new wells
Completed as Level 2, 4 or 5 junction
Can be developed bottom-up or top-down as required
Mechanical and hydraulic integrity of Level 4 junction with cement
Minimal milling required to re-open the mainbore
Full-gauge ID through completed mainbore and lateral
Permanent downhole latch coupling reference for depthand orientation control
A customer operating on a rigsite approximately 250 km from the Halliburton base in Nizhnevartovsk, Russia, sought to optimally produce an unconventional well by maximizing reservoir exposure after hydraulic fracturing operations had taken place in both the lateral and mainbore.
