Abstract: A variable orientation downhole actuation tool is made up of a first part which is adapted to be fixed with respect to the end of a down hole tube, and a second part which is adjustable with respect to the first part. The first and second parts are adjustable with respect to each other in any two of the three Euler angles possible angles, that is, the included angle or bend of a respective reference axis, the plane of included angle, or direction, and the rotation of the first body about its reference axis. It may also include a third part such that the third part is adjusted by at least one of the possible angles with respect to the second part, and the second part is adjusted by a further of the possible angles with respect to the first part. A passageway is provided between the first and second parts for the conveyance of material, gas, liquid, solid or some combination.

Abstract: A drillpipe line installation system, the drillpipe string being composed of drillpipe sections which are added and removed to increase and decrease the length of the drillpipe, and a length of cable is disposed within the drillpipe string. The length of this cable is greater than that of the drilipipe string when the cable is put in the drill pipe. The system includes a lower cable storage means which stows the cable in a compact manner and pays the cable out when the length of the drillpipe is increases, and an upper cable storage means which can take up the cable in a compact manner when the length of the drillpipe is decreased.

Abstract: An oil flow line and power device system has a tube for the transportation of oil and a power device which can be received in the tube. The tube is provided with an electric power transmission line extending along at least some of the length and has a first power transfer unit which can cooperate with a second power transfer unit on the power outlet device such that the other power transfer units cooperate to transfer power from the transmission line to the power device.
