Abstract
A system and methodology facilitates use of a diverter latch assembly in cooperation with a lateral wellbore. The diverter latch assembly comprises an upper latch assembly coupled with a lower latch assembly via a swivel. The upper latch assembly also comprises a releasable latch positioned to engage a tieback receptacle located in the well. The swivel and the releasable latch are designed to enable rotation of the releasable latch relative to a tubing of the lower latch assembly during release of the diverter latch assembly from the tieback receptacle. The rotational release system helps provide controlled release and withdrawal of the diverter latch assembly while reducing risk of damage to the diverter latch assembly or other downhole components.
