Implementations described and claimed herein provide apparatus and techniques for providing a seal for a polished rod. One example apparatus is a stuffing box. The stuffing box generally includes: a first flange configured to surround a polished rod; a second flange configured to surround the polished rod; a seal package disposed between the first flange and the second flang, the seal package being configured to surround and connect to the polished rod; and a flexible membrane surrounding the seal package, the flexible membrane being connected to at least a portion of the seal package.

The integration joint assembly includes an integration joint body (10) having a through bore (16), the body being for connection with a riser system. The integration joint assembly permits a tubular work string (50; 54) to pass there through such that there is an annulus created between the inner through bore (16) of the integration joint body (10) and the outer surface of the tubular work string (50; 54). The integration joint body (10) can also include at least two (300, 200) and more preferably three sealing devices (300, 200, 100) within its through bore (16). A method of drilling is also described as including the steps of installing an integration joint assembly in a riser string and running a tubular work string (50; 54) through the through bore (16) thereof.

An annular seal configured to prevent fluid from outside the wellbore from entering a well head stuffing box and tripping an anti-pollution control device. The seal comprising an elastomeric material and having a seam configured to allow the seal to installed on or in a stuffing box without dismantling well-head equipment.

A well annular pressure control device includes a housing having a through bore and at least two iris valves within the housing. The iris valves comprise a plurality of vanes operable between an open position and a closed position to define an opening. At least one actuator is coupled to the plurality of vanes to move the plurality of vanes between the open position and the closed position.

A wiper plug includes a mandrel and a seal unit disposed about the mandrel. The seal unit has a body and one or more fins extending outwardly from the body. An anti-extrusion assembly is disposed about the mandrel, and is arranged to transition between an initial configuration and an energized configuration. The anti-extrusion assembly limits extrusion of at least a portion of the seal unit.

A harsh environment integrated MPD riser joint includes a dynamic annular sealing system, a static annular sealing system disposed directly below the dynamic annular sealing system, and a flow spool, or equivalent thereof, disposed directly below the static annular sealing system. The dynamic annular sealing system may be a conventional ACD-type, RCD-type, or other conventional annular sealing system. The static annular sealing system may include one or more annular packer systems and one or more connection sealing elements that engage drill pipe during connection or non-rotation operations only. The dynamic annular sealing system may maintain annular pressure during drilling operations while the static annular sealing system is disengaged. The static annular sealing system may maintain annular pressure during connection operations while the dynamic annular sealing system is disengaged. Advantageously, the static annular sealing system is capable of withstanding jarring heaving action encountered in harsh environments.

A Jack-up drilling rig or land drilling rig riser system with quick connectors that can be used to rapidly install and de-install RCD housings between the BOP and the drill floor. The quick connector design can handle different bore diameters without changing the external design of the connector. The connector assembly may be used to connect a blowout preventer or rotating control device housing to a tubular riser, a blowout preventer housing to an RCD housing, or to join two tubular risers. A connector assembly connects a tubular pin end to a housing has a tubular connector body with a first end to receive the pin end and a second end secured to the housing. The connector assembly also includes a latching mechanism movable between a lock position to prevent the pin end from being removed and an unlock position in which the pin end can be removed.
