Abstract: Drill bit cutters and drill bits equipped with the cutters. The cutter is mounted on a bit to present the formation with a radiused, curving, side wall cutting face that is concave in one dimension and convex in another dimension. In a preferred form, the cutting face is in the form of a portion of a surface of revolution generated by an arc segment that is concave relative to the axis of revolution. The cutting face is formed on a layer of polycrystalline diamond disposed on a substrate of tungsten carbide. In another side wall cutter arrangement, a standard cylindrical cutter with a diamond cap is mounted to present the curved cylindrical side of the cap to the formation. Curved side wall cutting faces cut more efficiently than the usual flat end face of conventionally mounted cutters. A major portion of the diamond volume in a side mounted cutter trails the point of cutting face engagement with the formation to provide impact resistance and an increased diamond wear area.

Abstract: A system for pumping a selected fuel product from a storage tank to a dispenser includes a site controller, several fuel dispensers, each operable for dispensing a selected fuel product, and a data link connected to convey product information from a selected dispenser to the site controller. Several storage tanks each contain a different fuel product from each other tank, and also contain a submersible pump in each tank. A relay is connected to each pump. A submersible pump controller (SPC) is connected to each relay and the site controller. The SPC may also be connected to each dispenser. The SPC receives product selection information from the site controller and activates the relay connected to the pump in the storage tank containing the selected product, whereby the selected fuel product is pumped to the selected dispenser.

Abstract: Steel bit bodies are manufactured in a production process that employs polystyrene patterns in a lost foam casting process. The patterns are machined to permit the formation of complex shapes that cannot be reproduced in simple patterns that are extractable from reusable, two-piece pattern molds or dies. The patterns are machined from a billet material according to a basic, programmed, five-axis machining process to form multiple copies of a reproducible complex pattern body. The process is modified to produce multiple copies of a modified design. Machining the complex patterns and producing variations by changing the machine program permit multiple bit patterns of variable forms to be produced without need for building an intermediate, reusable pattern mold that would require multiple mold pieces, thus eliminating the associated time and expense required in the creation of a new pattern mold for each variation of the bit design.

Abstract: A valve assembly for controlling the flow of fluid through a conduit section having and an inlet and an outlet in which a ball valve having a through bore formed therein is rotatably mounted in the conduit section. The ball valve moves between an open position in which at least a portion of the bore registers with the inlet to permit the flow of the fluid through the ball valve, and a closed position in which fluid flow through the ball valve is prevented. An insert is disposed in the conduit section downstream of the ball valve, and a first series of passages are formed through the insert for receiving the fluid from the ball valve. At least one addition series of passages extend through the insert for receiving fluid from the first series of passages and discharging the fluid to the outlet, with the passages reducing the noise generated by the fluid flow.

Abstract: An actuator assembly for moving a device between a retracted and extended position in which a ball screw is connected to the device and is in threaded engagement with a ball nut so that, upon rotation of the ball nut, the ball screw moves between a retracted and an extended position. A gear train is connectable between a power source and the ball nut for transferring torque therebetween to rotate the nut member, and a control system responds to a relatively low power input for selectively connecting the drive assembly between the power source and the ball nut member.

Abstract: An acoustic logging tool, useful for creating a circumferential image of an earth borehole or well casing, which includes one or many acoustic transceivers mounted in substantially the same plane, in a drill string sub. The mounting receptacles are located in blocks, flexibly mounted in fixed inserts within the interior of the drill string sub. Each of the transceivers is structured to provide temperature and pressure compensation. The echo signals received by the transceivers are digitized and processed to eliminate extraneous noise created by the ringing of the transducers, by the signals reflected from the material backing the transducer ultrasonic element, and by any other sources inherent to the drilling environment. Digitization and further processing also allows for signal enhancement, thus allowing detection of signals in the presence of substantial noise.

Abstract: A fluid system and method according to which a first fluid, a second fluid, or a blend of the fuels is passed to a first meter for measuring the flow thereof while the second fluid is passed through a second meter before it passes to the first meter. The flow of the first fluid to the first meter and the flow of the second fluid to the second meter and then to the first meter are controlled by valves and, as a result, a predetermined ratio of the blended fluids can be established and maintained. The second meter can be calibrated based on the first meter and therefore does not have to inherently provide relatively accurate volumetric measurements. Thus, the second meter can be less costly than the first meter.

Abstract: A deployment tool for communicating a well tool from a generally vertical wellbore to a lateral wellbore includes a hollow tube having a generally uniform inside diameter. The tube includes at least one flex portion disposed intermediate a first end and a second end of the tube to allow for angular deflection of the second end of the tube with respect to the first end of the tube. The flex portion also maintains the generally uniform inside diameter of the tube during the angular deflection. The deployment tool also includes a locking device attached to the first end of the tube for releasably securing the first end of the tube at a selected location in the vertical wellbore adjacent to the lateral wellbore. The tube of the deployment tool includes a length selected to allow the second end of the tube to extend into a portion of the lateral wellbore when the first end is releasably secured at the selected location in the vertical wellbore.
