The steering assembly (20) includes upper (26) and lower (28) tubular housings connected by a universal joint (30). An angle cam is disposed on the end of the lower housing and projects into the upper housing. A plurality of wedge members (90) extend axially from the upper housing and into engagement with the angle cam (80). Drive trains are connected to the wedge members to move the wedge members toward and away from the angle cam so as to pivot the lower housing at the universal joint and change the angle and azimuth of the lower housing with respect to the upper housing. The lower housing is connected to a bearing pack (16) supporting a drill bit (12) such that upon changing the angle and azimuth of the lower housing, the direction of the drilling of the drill bit is also changed. The steering assembly being connected to composite tubing having conductors in the wall thereof for conducting data and commands between the steering assembly and a processor at the surface and for providing power to the steering assembly. Data on the position of the bit is transmitted to a processor which determines the direction of drilling and selectively transmits commands to the steering assembly to change the bend angle and direction of the drilling of the bit.

| An offshore floating platform for the drilling and/or production of petroleum products from the seabed includes a production deck and a buoyancy apparatus vertically guided and restrained within the platform. The buoyancy apparatus includes a well deck on its upper surface on which are mounted at least two surface trees. At least two vertical risers are supported by the buoyancy apparatus and are attached to the well deck. Each of the risers is connected to one of the surface trees and extends down through the buoyancy apparatus for connection to a seabed wellhead. At least one tendon assembly secures the buoyancy apparatus to the seabed. The tendon assembly is constructed with at least two concentric tubular tendon elements, and it is attached to the well deck and extends along the vertical centerline of the buoyancy apparatus. A manifold on the well deck is fluidly coupled to the surface trees through a pressure reduction choke, and a low pressure jumper fluidly couples the manifold to petroleum handling apparatus on the production deck. | ||||||

| The invention concerns a method and a device for directional drilling of a hole (3), in particular when drilling curved holes for mining, drift mining or similar, whereby a drill support (4) is used in the form of a flexible continuous drill tube with a proximal end and a distal end, that at the end of the drill support distal end is connected a down hole assembly (5) comprising a drill bit (13) for forming a drill string, which is fed into the gradually forming hole. To avoid and minimise the occurrence of “stick slip” during directional drilling, according to the method, the drill support (4) while drilling is taking place is held fixed at its proximal end against rotation outside the borehole and the rotating motion for indexing the drill bit (13) around an axis extending in the direction of drilling is performed in the area between the drill support’s distal end and the drill bit while drilling is in progress. | ||||||

| Apparatus for recovering logging tools and the like from a wellbore as part of a drilling operation such as for oil wells, irrigation systems and the like. The apparatus comprises the use of a flexible connector member (44) in the form of a flexible wire rope, or strand, or cable which is provided with socket members (46, 48 or 146, 148) attached with resin (54) or by being swaged or crimped to the flexible member (44). The apparatus takes the place of the conventional rigid sinker bar assembly that causes safety concerns when used with a top drive housing. | ||||||
| 276 | RELEASABLE CONNECTOR | EP00950095.0 | 2000-08-04 | EP1409837A1 | 2004-04-21 | BAKKE, Stig |
| A connector (10) with an axial bore (12) therethrough has a connecting end (22) for coiled tubing, and a connecting end (20a) for a downhole tool, and is arranged to be released and divided into two sleeve-shaped parts (14 and 16, 20). In a spring chamber (44) for a piston body (23, 23a) and with the purpose of delaying release, there is filled lubricating grease, for which extrusion channels are provided. The lubricating grease must first be forced out of the spring chamber (44) by means of the piston body (23, 23a) before the spring (42) thereof can be fully compressed and allow displacement of the piston body into its end position to release an expandable locking ring (17) and release the connector. Because of the delay achieved, the interconnection of the two parts (14 and 16, 20) can be restored, if an unintentional pressure build-up inside the connector ceases before the locking ring (17) has been brought completely out of its active position. | ||||||

| 280 | SECTIONAL DRIVE SYSTEM | EP97924634 | 1997-05-09 | EP0901558A4 | 2002-03-20 | COUSINS JAMES E; MARKIEL GEORGE R; BOYTER RUBEN C |
| A sectional drive system for transmitting power linearly or in a curved path to an output, which system includes multiple tapered and splined, interlocking driving segments (17) which are nested and stacked as a segment string (10) that is rotatable in a guide path. The top one of the segments cooperates with a drive mechanism (12) to effect rotation of the nested segments in concert and the bottom one of the segments connects to a suitable output such as drill bit (42). Articulation of the segments with respect to each other due to matching asymmetrical splines (19) and companion spline slots (24) facilitates dampening of drive vibration and bending of the segment string in the guide path in any desired direction to facilitate transmitting power in a curved path of desired magnitude from the drive mechanism to the output. In a typical application the interlocking driving segments are incorporated in a downhole drilling apparatus designed for insertion in a well bore to facilitate drilling holes at selected angles in an uncased hole or through the well casing (7), cement sheath and producing interval to enhance well production. The driving segments and bit will continue travelling in a straight line and continue on the same path presented when existing the guide path from the downhole drilling apparatus. | ||||||
