A drill string circulation apparatus has a sleeve member with an elongated tubular body and a longitudinal bore, with an outer diameter suitable for being sealingly gripped by a blowout preventer. A drill string has an outer diameter sized to fit within the sleeve member bore, and has one or more seals disposed on an exterior surface. The seals are sized to create a seal between said sleeve member and the drill string, when the drill string and seals are positioned within the sleeve member bore, while said drill string is still capable of reciprocation and/or rotation within the sleeve member when the seals are within the sleeve member bore.

Drill string circulation apparatus

A power tool for unlocking a releasable attachment pin from at least two ground covers includes at least one gripper carried by a carrier and selectively moveable relative to the carrier to grip a first portion of the attachment pin. At least one rotator also carried by the carrier is selectively rotatable relative to the first portion of the attachment pin to rotate a second portion of the attachment pin to unlock the attachment pin from the ground covers. A power-driven actuator associated with the carrier is operatively coupled to the rotator(s) and configured to selectively rotate the rotator(s).

Systems, apparatus and methods for manipulating a ground cover attachment pin

A diverter assembly includes a tubing segment and one or more sleeve members disposed therein. The tubing segment includes apertures that are selectively alignable with apertures of an inner sleeve disposed within the tubing segment. The tubing segment includes a series of stops (e.g., shear pins) to arrest movement of the first sleeve within the bore of the tubing segment. A first one or more ball seats are included in the first sleeve such that deployment of a first ball and pressurization of the well above the first ball causes a first set of shear pins to fail, thereby allowing the first sleeve to slide downhole to cause apertures of the sleeve to align with apertures of the tubing segment, thereby causing fluid to flow to an annulus between the tubing segment and wellbore wall.

Top-down squeeze system and method

A locking pin for connecting at least first and second adjacent mats of a support surface includes a body and at least one foot operatively connected to the body and configured to secure the locking pin to the mats. The foot is selectively movable from an unlocked position to at least one locked position and then, while in a locked position, selectively moveable upwardly relative to the body and the first and second mats.

Apparatus and methods for connecting components of a support surface

Systems and methods for heaters used in treating a subsurface formation are described herein. Certain embodiments relate to systems for insulated conductors used in heater elements. More particularly, fittings for splicing together insulated conductors and/or insulated conductors to other conductors are described.

Systems for joining insulated conductors

A method for coupling an end of a first insulated conductor to an end of a second insulated conductor that includes placing a sleeve over the end of the first insulated conductor and the end of the second insulated conductor; filling an interior volume of the sleeve with electrically insulating material; and moving the end of the first insulated conductor and the end of the second insulated conductor towards the center of the sleeve. When the ends of the insulated conductors are moved together an end of a core of the first insulated conductor and an end of a core of the second insulated conductor are coupled inside a core coupling located inside the sleeve and the electrically insulating material is compressed between an end portion of an electrical insulator in the first insulated conductor and an end portion of an electrical insulator in the second insulated conductor.

Press-fit coupling joint for joining insulated conductors

A fitting for coupling an end of a first insulated conductor to an end of a second insulated conductor is described. The fitting includes a sleeve placed over the end of the first insulated conductor and the end of the second insulated conductor and a core coupling located inside the sleeve. The core coupling fits around an end of a core of the first insulated conductor and an end of a core of the second insulated conductor. An interior volume of the sleeve is at least partially filled with electrically insulating material. The electrically insulating material is compressed with an end portion of an electrical insulator in the first insulated conductor and an end portion of an electrical insulator in the second insulated conductor when the fitting is coupled to the insulated conductors.

A method and apparatus is provided for removing fluids, particularly entrained and/or adherent fluids, from drill cuttings generated during the well drilling process. A generally cylindrical wire-wrapped screen having a bore therethrough rotates about its longitudinal axis. Suction pressure is applied through the inner bore of the cylindrical wire-wrapped screen. As fluid-laden drill cuttings are deposited on the outer surface of the cylindrical wire-wrapped screen, fluids are drawn off of the cuttings and evacuated from the inner bore of the cylindrical wire-wrapped screen. Solid components of the cuttings remain on the outer surface of the cylindrical wire-wrapped screen and eventually roll off the screen. A scraper member is provided to agitate cuttings deposited on the outer surface of the cylindrical wire-wrapped screen.
