Abstract: The subsea intervention system (SIM) includes a BOP module 10 and CT module 20. A tool positioning system 76 is used for positioning a selected subsea tool 22 stored within a rack 18 with a tool axis in line with the BOP axis, while a marinized coiled string injector 80 is moved by positioning system 81 to an inactive position. Power to the subsea electric motors 162 is supplied by an electrical line umbilical extending from the surface for powering the pumps 164, with the hydraulic system controlled by power control unit 198. The injector 80 preferably includes a pressure compensator roller bearing 220 and a pressure compensated drive system case 254.

Abstract: A member having a body, the body having two spaced-apart ends, wave energizable identification apparatus which, in one aspect, is radio frequency identification apparatus with integrated circuit apparatus and antenna apparatus on the exterior of the body, and encasement structure encasing the identification apparatus, the encasement structure, in certain aspects, including one or a plurality of layers of heat resistant material and, in certain aspects, at least one layer of heat resistant material, and methods for producing such a member.

Abstract: A rig, the rig useful in well operations, the rig having rig structure above the earth, and heat transfer loop apparatus connected to the rig for supplying heat transfer fluid for use on the rig, either from a loop or loops with portion(s) in water or portion(s) in earth, or both.

Abstract: A method for guaranteeing a consumer a best price on an item purchased from a vendor in a first transaction at a first price, the method including recording the first price and information identifying the consumer, monitoring the sales price of the item for a predetermined time period after the first transaction, noting any price lower than the first price for the item during the predetermined time period, calculating a money-value difference between the first price and said any price lower than the first price, and refunding to the consumer an amount equal to the money-value difference.

Abstract: A controller provides an automatic bit protection sequence for an autodriller that can be initiated during the initial stage of set down of the bit within the formation. The automatic protection sequence establishes a setpoint for a parameter of interest (such as weight on bit, ROP, torque) associated with operation of the drilling system and then initiates a gradual increase in that parameter in order to achieve the setpoint. The bit protection sequence may be adjustable so that varying degrees of gradualness may be selected. The controller of the autodriller may also be provided with measured data for torque, rate of penetration (ROP) and/or the differential pressure of the mud motor of the drilling system. Each of these parameters is provided with a predetermined setpoint, and each may be selected as the controlling parameter for operation of the autodriller.

Abstract: A method for making a screen assembly for use in a vibratory separator, the method, in certain aspects, including producing a heated first screen assembly; cooling the first screen assembly while a second heated screen assembly is being made; and cooling the second screen assembly while a third heated screen assembly is being made—with heating apparatus adjacent cooling apparatuses.

Abstract: A method for installing a heat exchange pipe loop in a borehole, the method, in at least certain aspects, including drilling a borehole with a sonic drill system having a head and casing connected thereto, a drill apparatus on a lower end of the casing movable by the sonic drill head to drill the borehole, pumping fluid into the casing and up to earth surface in an annular space in the borehole so that drilled material flows to the earth surface, lowering a heat exchange pipe loop having a lowermost U/bend member down into the casing, introducing grout into the casing around the heat exchange pipe loop, and extracting the casing from the borehole.

Abstract: An apparatus for transporting solid waste drill cuttings material produced in the drilling of an oil or gas well, the apparatus including: a waste supply apparatus; a feeder to transport the material; a pneumatic conveying apparatus to which the material is transferred from the feeder; at least one blockage sensing device in the conveyor; and a control apparatus for controlling feed rate of the feeder.

Abstract: An apparatus for rotating a tubular, the apparatus, in at least certain aspects including a frame, a rocker assembly connected to the frame, the rocker assembly including a top rocker arm pivotably mounted to the frame, and a bottom rocker arm pivotably mounted to the frame, top torque apparatus connected to the frame, upper gripper apparatus connected to the frame for gripping a primary tubular (e.g., but not limited to a first pipe), lower gripper apparatus connected to the frame for gripping a secondary member (e.g.

Abstract: Interconnectible screen assemblies for vibratory separators or shale shakers and methods for manipulating such screen assemblies which, in certain aspects, include a first screen assembly and a second screen assembly positioning at least a portion of the first screen assembly with respect to screen assembly holding apparatus, connecting a second screen assembly to the first screen assembly, and moving the first screen assembly and the second screen assembly together with respect to the screen assembly holding apparatus.

Abstract: A top drive drilling system, in at least some aspects, having a top drive unit, and a pipe gripping system beneath the top drive unit which has an open throat for receiving a tubular to be gripped by the pipe gripping system; and, in at least certain aspects, the gripping system having a body with first and second jaws movably connected thereto and piston/cylinder devices movably interconnected with each jaw for moving the jaws to clamp and then to rotate the pipe.
