摘要： A drill pipe mountable wellbore cleaning tool apparatus is of an improved configuration that enables attachment to a drill pipe joint having first and second connector end portions and a cylindrically shaped portion in between the connector end portions. The drill pipe joint with attached debris cleaning tool or tools is made part of a drill string. The apparatus includes a support sleeve that is mounted to the drill pipe joint in between the connector end portions. The support sleeve abuts but does not invade the integrity of the cylindrical portion. Centralizers are attached to the opposing ends of the support sleeve, with each centralizer overlapping a portion of the support sleeve. The support sleeve carries one or more debris cleaning tools in between the centralizers. These tools enable debris to be removed from a wellbore. At least one locking clamp is attached to the cylindrical portion next to a said centralizer. The locking clamp prevents the support sleeve from moving longitudinally along the drill pipe joint.

摘要： What is provided is a method and apparatus which can be detachably connected to an annular blowout preventer thereby separating the drilling fluid or mud into upper and lower sections and allowing the fluid to be displaced in two stages, such as while the drill string is being rotated and/or reciprocated. In one embodiment the sleeve can be rotatably and sealably connected to a mandrel. The swivel can be incorporated into a drill or well string and enabling string sections both above and below the sleeve to be rotated in relation to the sleeve. In one embodiment the drill or well string does not move in a longitudinal direction relative to the swivel. In one embodiment, the drill or well string does move longitudinally relative to the sleeve of the swivel.

摘要： A duplex snubbing jack and method of snubbing pipe into a well bore which includes first and second gripping units that alternately and synchronously grip and release a length of pipe to be attached to a pipe string. The first and second gripping units are synchronously movable upward and downward toward and away from each other to push or pull the pipe through a BOP stack and into or out of a wellbore. Linear actuators are used to synchronously move the first and second gripping units. Guide rails are provided to laterally support the pipe as the pipe is pushed or pulled through the BOP stack into or out of the wellbore. The first and second gripping units are preferably slip-type spiders.

摘要： A drilling mud remediation and drilling cutting treatment device and method. There are three main components: a vacuum liquid solid separator; a pelletizer; and an induction furnace. The liquid solid separator has a seamless filter belt configured to carry a mixture of liquids and solids over a vacuum. A slurry comprised of drilling mud and cuttings is deposited on the filter belt. An applicator ensures that the slurry is deposited evenly across the entire filter belt at a uniform thickness. The vacuum removes most of the liquids for further treatment and reuse. The solids are transferred to a pelletizer which compacts them into relatively uniform pellets while removing much residual liquid. The pelletized cuttings are then passed through an induction furnace, which removes any residual liquids, renderings the cuttings safe for disposal.
