His innovative approach has led to the development of a unique mechanism that enhances the efficiency of pack-off units.

Latest Patents

Miller holds a patent for a "Pressure actuated pack-off and method." This invention involves a mechanism designed to achieve the radial expansion of an annular elastomeric pack-off unit. The mechanism operates between the bore of a casing and the exterior of a liner. It comprises a tubular sealing assembly that is threadably connected between the liner and the hanger. This assembly defines two inwardly projecting annular seals, an annular fluid pressure chamber, and radially disposed fluid inlet ports. These ports are strategically located between the two inwardly projecting annular seals. An annular piston mounted in the pressure chamber facilitates the compressible expansion of an elastomeric seal element. The design also includes a tubing extension of the work string, which can be selectively moved into sealing relationship with either or both of the internally projecting annular seals. During cementing operations, the tubing extension engages both seals, and after cementing, it can be elevated to disengage from the lowermost seal, allowing fluid pressure to actuate the piston.
