摘要： A sub surface deployment valve which is particularly suitable for use in underbalanced drilling operations which can be installed through an existing tubular string comprises a radially expandable body (1) having an internal bore and a valve element (2) capable of closing off the internal bore. The deployment valve can be installed by passing the valve through the existing tubular and then radially expanding the radially expandable body of the deployment valve to form a connection resulting from the interference between the external surface of the deployment valve and the tubular string.

摘要： A method of drilling a second wellbore section ( 12 ) from a first wellbore section ( 10 ) that is lined with a tubular liner ( 11 ) using a remotely controlled electrically powered drilling assembly that is suspended from a cable ( 1 ) and of periodically interrupting the drilling operation to extend the tubular liner into the second wellbore section without having to pull the assembly from the wellbore. The drilling assembly comprises an expansion means ( 2 ), a traction means ( 3 ), and an electrically actuated drill bit ( 6 ). An expandable liner pipe ( 19 ) is introduced into the wellbore by disconnecting a cable connection means ( 15 ) at the surface to separate the upper ( 13 ) and lower ( 14 ) lengths of cable, arranging the expandable liner pipe ( 19 ) concentrically about the upper ( 13 ) or lower ( 14 ) length of cable, reconnecting the cable connection means ( 15 ) to rejoin the upper ( 13 ) and lower ( 14 ) lengths of cable and running the expandable liner pipe ( 19 ) into the wellbore supported on a cable traction means ( 20 ) that is moveable along the cable.

摘要： When drilling or completing an oil or gas well, it is often desirable to drill a borehole at an angle to the initial borehole. A process for deflecting a well tool towards the wall of a well bore comprises positioning within the well bore a radially expandable pipe designed to curve longitudinally when its diameter is expanded, expanding the diameter of the radially expandable pipe thereby causing the pipe to curve and passing the well tool through the curved pipe: The process is particularly suitable for through-tubing operations in which a lateral bore is initiated from a production well having within the well a smaller diameter production tubing ( 14 ) comprising (i) passing through the production tube ( 14 ) a radially expandable pipe ( 1 ) designed to curve longitudinally as its diameter is expanded, into a section of well bore ( 12 ) having a diameter greater than the diameter of the production tubing ( 14 ) (ii) expanding the diameter of the radially expandable pipe ( 1 ) thereby causing the pipe to curve, (iii) passing through the curved pipe a milling device or drill bit and (iv) milling the casing or drilling into the well bore wall.

摘要： A method for connecting tubular elements (37, 40), particularly pipe for strings to be used in oil and gas wells, comprises: (A) locating a portion o f a first tubular element (37) within a portion of a second tubular element (40), (B) expanding the portion of the first tubular element and/or compressing the portion of the second tubular element to form a connection resulting from the interference between the external surface of the portion of the first tubular element and the internal surface of the portion of the second tubular element, in which, prior to assembly, one or both of the external surface of the portion of the first tubular element and. the intern al surface of the portion of the second tubular element is/are at least partial ly coated by plasma spraying with hard angular material. Preferably, protuberances (38) of plasma-sprayed hard angular material are formed on at least one of the mating surfaces of the connection.
