| 105 | Annular Drilling Device | US14719120 | 2015-05-21 | US20150376970A1 | 2015-12-31 | William James Hughes |
| An annular drilling device is provided that employs an active or passive, stationary sealing element. More specifically, rotating annular drilling devices commonly used depend on externally pressurized sealing elements that are energized by wellhead pressure or hydraulic pressure to grip a rotating drill pipe and rotate with the drill string. Thus, a plurality of rotary seals and bearings must be used. Here, however, the passive or active sealing element is stationary, thereby eliminating the need for bearings, etc. The passive or active stationary sealing element is made of a low-friction material that contacts the drill pipe, creates a seal, and does not adversely affect drilling operations. | ||||||

| 110 | APPARATUS AND METHOD FOR STRIPPING SOLIDS AND FLUIDS FROM A STRING USED IN DRILLING OR SERVICING WELLS | US14156211 | 2014-01-15 | US20140124222A1 | 2014-05-08 | Quinn A. J. Holtby |
| An apparatus and method is provided for stripping solids and fluids from a string used in the drilling or servicing of a well when the string is removed from the well. The apparatus can comprise two or more pivotally connected arcuate body portions that can be enclosed around the string in a clamshell fashion. The apparatus can further comprise a seal disposed therein to provide a toroidal sealing member around the string when the apparatus encloses the string. A quick release latch mechanism is provided on the apparatus for easy and quick installation on, and removal from, the string. Handles on the apparatus allow personnel to hold the apparatus in a stationary position as the string passes through the apparatus when being raised from the well. In so doing, the sealing member strips solids and fluids from the string. | ||||||
| 111 | Packing unit for reciprocating pump polished rod | US13090177 | 2011-04-19 | US08631861B1 | 2014-01-21 | Randolph A Busch |
| A packing unit is provided for use with a well having a reciprocating pump and polished rod. Packing assembly seals, a barrier fluid and a pressure transmitter cooperate with housed components to regulate the pressure on either side of a first packing sub-assembly and to pressure one side of a second packing sub-assembly. The barrier fluid is contained above the first packing sub-assembly and below the second packing sub-assembly with well fluids and accompanying pressures being contained below the first packing sub-assembly, such that, if leakage occurs, relatively clean barrier fluids are leaked instead of well fluids. The well fluids pressure and barrier fluid pressure are substantially balanced across the first packing sub-assembly. The first packing sub-assembly and second packing sub-assembly include components allowing their respective packing seals to move with, and remain sealed against, the polished rod when it deviates angularly or translationally from the initial vertical orientation. | ||||||
| 112 | WIPER ASSEMBLY FOR A PUMP | US13850143 | 2013-03-25 | US20130259647A1 | 2013-10-03 | John Edward Stachowiak, JR. |
| A wiper assembly may be used to prevent wellbore debris from entering an operating region of a pump. The wiper assembly may include a housing, a wiper member, a backing member, and a biasing member. The biasing member may bias the backing member into engagement with the wiper member, and thereby bias the wiper member into engagement with a tapered surface of the housing. The wiper member may include a corresponding tapered surface, which thereby forces the wiper member radially inward into engagement with an operating member of the pump. | ||||||
