The cable management assembly includes a first support member having a cable attachment portion that supports the cable along a first length; and, a second support member having a cable attachment portion that supports the cable along a second length. The support members are arranged to pivot with respect to each other about a pivot axis as the component moves between received and withdrawn positions in the rack. The first and second lengths of cable are offset from each other in the direction of the pivot axis. | 2010-10-14 |
20100258351 | SYSTEM, METHOD AND APPARATUS FOR DOWNHOLE SYSTEM HAVING INTEGRATED MEASUREMENT WHILE OPERATING COMPONENTS - A drill bit string has an internal steering module for measurement while drilling. A chassis is inserted into a modified drill collar from the axial end, rather than through the side. The chassis has external pockets machined into it from its outer diameter The size of the longitudinally milled slots in the chassis is determined by the size of the components. The mud flow path is positioned off-center because of the component slots. The geometric shape of the flow path through the tool is shaped to optimize the flow area and maintain a wall thickness that can withstand the mud pressure. The wall thickness surrounding the flow area is proportional to the maximum hydrostatic pressure and the circulation pressure. | 2010-10-14 |
20100258352 | System And Method For Drill String Vibration Control - A drilling assembly includes a derrick, a swivel assembly coupled to the derrick, and a drill string coupled to the swivel assembly. The drill string includes a plurality of pipe sections, each having an insert providing a material and/or geometrical discontinuity in the pipe section, the plurality of pipe sections forming periodic cells collectively operative to selectively block propagation of vibrations in the drill string. | 2010-10-14 |
