  • Method and apparatus for cleaning a wellbore
    Patent number: 11649697
    Abstract: An apparatus performs a method for cleaning a wellbore. The apparatus is a jet sub including an engine, a flow diverter and mixing throat. The engine propels a driving fluid at a first end of the jet sub towards a second end of the jet sub along a longitudinal axis of the jet sub. The flow diverter redirects the driving fluid by a redirection angle that is an obtuse angle. The mixing throat receives a mixed fluid including the driving fluid from the flow diverter and induced fluid drawn into the mixing throat by the driving fluid. The mixed fluid is injected into an annulus of the wellbore at the obtuse angle.
