TopJet

The TopJet is an increasingly popular solution, used on a number of rigs to speed up Run in Hole (RIH) with closed-end assemblies.  The top filling coupling is quick to install, injects fluid more rapidly and simultaneously allows air and spray to vent downwards. Commonly used when the string is being run in hole with full floats/NRVs, the device rests and seals between the drill-pipe and top-drive to reduce filling time delays and overspill.
