Plug and pump system for routing pressurized fluid
A plug and pump system for routing pressurized fluid from a fluid source is disclosed. The system includes a platform and a docking station interface mounted on the platform and including multiple points of articulation. A wellhead interface is mounted on the platform and includes multiple points of articulation. The docking station interface and the wellhead interface are configured to route pressurized fluid from a fluid source.
WASHPIPE SYSTEM AND METHOD
A washpipe seal and method includes providing a first sliding mechanical face seal between two seal elements to seal a mud conduit, and a second mechanical face seal between two additional seal elements to define a cavity within a housing of the washpipe between the first and second mechanical face seals and independently from the mud conduit, and in which, during operation, a buffer fluid can be provided.
BUILT-IN END COUPLING FOR HIGH PRESSURE REINFORCED BONDED RUBBER HOSE ASSEMBLIES
One aspect of the disclosure is a method of attaching a hose coupling to a reinforced hose. In one embodiment, the method comprises: skiving the first end of the reinforced hose to expose at least one reinforcing layer of a plurality of reinforcing layers of the reinforced hose; positioning the skived first end of the reinforced hose in an inner cavity of the hose coupling; introducing a vacuum into the inner cavity through a vent port in the hose coupling; and introducing a bonding agent into the cavity through an injection port in the hose coupling, wherein the bonding agent is drawn by the vacuum into the plurality of reinforcing layers of the reinforced hose.
Labyrinth seal swage coupling for high temperature/pressure reinforced rubber hose and methods of attachment
A Specialized Fitting and a Method of Manufacture for swaging hose couplings to high pressure, high temperature reinforced rubber hose having a corrugated or smooth plastic/nylon/elastomer or metal lining (inner tube). The hose couplings include a stem having first hose grippers extending from and along a length of the outer surface; elastomeric sealing members located around and disposed along a length of the outer surface of the stem; and a ferrule attached to the stem adjacent ensuring a labyrinth seal between the inner tube and the hose coupling.

Tubular handling tool
An elevator for use in handling a tubular includes a first body part coupled to a second body part; and at least two slips coupled to each of the first and second body parts, wherein one or more of the slips includes an engagement member for coupling with a mating member of the first body part or the second body part, wherein at least 25% of the engagement member is coupled with the mating member when the slip is in an open position. In another embodiment, a swivel includes an upper housing rotatably coupled to a lower housing; and a rotary union having a rotating body attached to the lower housing and a non-rotating body attached to the upper housing, wherein the swivel is configured to transfer load from the lower housing to the upper housing.

Method and system for evaluating tubular makeup
Methods and systems for connecting threaded tubulars are presented. One example method generally includes engaging threads of the tubulars; engaging the first tubular with a clamp of a makeup tool; rotating the clamp of the makeup tool, thereby rotating the first tubular relative to the second tubular and making up the threaded connection; measuring turns of the first tubular; measuring turns of the clamp; and evaluating the threaded connection by comparing the measured turns of the first tubular and the measured turns of the clamp. One example system generally includes a makeup tool operable to rotate a first threaded tubular relative to a second threaded tubular. The makeup tool includes a clamp configured to engage the first tubular. The tubular makeup system further includes a first turns counter configured to measure turns of the first tubular; and a second turns counter configured to measure turns of the clamp.
Method and system for evaluating tubular makeup
Methods and systems for connecting threaded tubulars are presented. One example method generally includes monitoring relative rotation between a backup tong and a tubular clamped in the backup tong to determine slippage of the backup tong.
