  • Method and apparatus for launching multiple balls in a well
    Patent number: 9103183
    Abstract: A ball launcher for dispatching balls into a wellbore that includes a manifold for selective attachment to a wellhead assembly and a magazine mounted on the manifold in which the balls are stored for distribution to the manifold. Chambers are provided in a cylinder in the magazine, so that by rotating the cylinder the chambers register with a bore in the manifold, through which the balls are delivered to the wellbore. Flowing a flushing fluid into the bore in the manifold urges the balls downward. An auxiliary line through the manifold provides a conduit for the flushing fluid into the bore.

  • Scalloped landing ring
    Patent number: 8919453
    Abstract: A landing ring having at least one scallop groove formed on an interior of the ring. The landing ring interfaces with a fluted mandrel casing hanger such that the scallop groove aligns between flutes of the hanger. This alignment of the scallop groove of the landing ring with the fluted mandrel casing hanger provides sufficient clearance to allow a stabbing in of a cement tube for cement injection during cement topping operations or debris clean out down hole.
