Abstract: The present invention generally relates to a connector arrangement for connecting a first tubular to a second tubular. In particular, the present invention relates to methods and apparatus for connecting the tubulars in such a way that the connection is prevented from becoming unmade in response to expansion of the tubulars. A connector mechanically mates a box end and a pin end of the tubulars together to form the connection. Additionally, mating castellations, surface finishes on the pin end and the box end, torque screws, and a variable pitch groove can provide resistance to relative rotation between the tubulars at the connection.

Abstract: A power tool has a mechanism for ejecting a battery pack which includes a receiving frame which defines a cavity to receive a battery pack. A receiving member is adjacent the cavity. The receiving member meshes with a member on the battery pack to hold the battery pack in the cavity. A biasing member is in the cavity adjacent the receiving member. The biasing member ejects the battery pack from the ejecting mechanism. A member retains the biasing member in the cavity. The member guides a portion of the battery pack meshing with the receiving member into contact with the biasing member such that when the battery pack is locked onto the frame, the biasing member is in a compressed condition and when the battery pack is an unlocked position, the biasing member ejects the battery pack from the frame.

Abstract: A portable pipe installation/removal support apparatus for assisting in the installation/removal of a series of connectable pipe strings from a ground-level borehole. The support apparatus has a base, an upright extending from the base, and, in an exemplary embodiment, a pair of catch arms extending from the upright to define a catch platform. The pair of catch arms serves to hold an upper connector end of a pipe string at an operator-convenient standing elevation by releasably catching an underside of a pipe coupler connecting two pipe strings of the series of connectable pipe strings. This enables an operator to stand upright while coupling/uncoupling the series of connectable pipe strings during the installation/removal thereof from the ground-level borehole. Additionally, a process for installing and a process for removing a series of connectable pipe strings is disclosed utilizing such a support apparatus.

Abstract: The invention comprises a section of improved tubing with coupled end connectors and an insert containing at least one electrical wire. The insert has an outside diameter that is approximately equal to the inside diameter of the improved tubing. The insert also has projections at each end such that when two inserts are placed end to end, the projections will mate up. The insert has at least one groove cut into its side and running the length of the insert. The groove is for the placement of a wire for transmission of power to the well bore or for the placement of a wire for transmission of data from the well bore. When a plurality of the inventions are placed end to end, the insert projections line up the electrical connectors and correct mating of the insert projections will result in correct mating of the electrical connectors.

Abstract: A wellhead assembly is provided having a first tubular member, and a second tubular member at least partially extending over a first end of the first tubular member defining an annular space there between. An arcuate lock member such as a lock ring is located within the annular space. At least one load applying member penetrates the second tubular member and urges the arcuate lock member against the first tubular member. A lock nut is coupled to an inner surface of the second tubular member. A method for coupling the first tubular member to the second tubular member is also provided.

Abstract: A method of installing a conductor or a casing in the sea bed, the conductor or casing being caused to penetrate a sea bed, the conductor or casing being substantially suspended from a length of coiled tubing. The conductor or casing being lowered to the sea bed by means of the coiled tubing, the coiled tubing being deployed from a reel on a floating vessel. Ideally a conductor may be deployed in the sea bed at the desired location, and subsequently a casing is introduced to the conductor. Alternatively the casing is introduced into a conductor, the casing and conductor substantially suspended from a length of coiled tubing, lowered to the sea bed by means of the coiled tubing, and caused to penetrate the sea bed. A length of coiled tubing is then introduced to the conductor or casing.

Abstract: A system and method for preventing blowouts during the deployment of a casing string into a wellbore. The system includes securing a casing coupling to a casing string and securing a retrievable check valve within the casing coupling. The retrievable check valve allows fluid from the surface to be pumped through the retrievable check valve. However, the retrievable check valve prevents upward fluid flow from the wellbore through the retrievable check valve to the surface.
