    摘要: Degradable polylactic or polyhydroxyalkanoate polymers may be used to viscosify aqueous fluids for use in wells, Sand control screen or liner can be coated with a solid degradable polymer during placement in a well. Mechanical changes or flow changes in a well can be caused by solid degradable polymer that changes physical properties after it is placed in a well. Parts of devices or entire devices can be made of solid degradable polymer that converts to a fluid after selected times in an aqueous environment in a well.

    摘要: An economical computer-controlled non-invasive laser apparatus and method to perform anterior segment surgery in an eye are disclosed. The laser source may include a pumping laser, a Nd:YAG laser cavity gain media, a stimulated Raman converter crystal, intracavity beam diameter-reducing optics, and an intracavity Q-switching crystal. The laser pulses have a selected wavelength for anterior segment surgery. A laser pulse delivery and treatment control mechanism and method for the practicing surgeon are also provided. The laser pulses and delivery system may be used in anterior segment surgery for cataracts, where the laser pulses may be used to form the capsulotomy, to form the corneal incision or to disintegrate contents of the capsule before removal. The laser and delivery system may also the used to treat a capsule and lens for correcting or preventing presbyopia and to treat a cornea to correct visual deficiencies in an eye.

    摘要: A suction manifold mounting for a fluid end of a high pressure pump having a frame assembly. The fluid end has a body forging with a detachable suction manifold plate. The plate is pivotally attached at opposed ends to a pair of swivel arms through a cooperating pair of yoke limbs. The swivel arms are rigidly affixed to the frame member. When attachment bolts are removed from the manifold plate, the plate may pivot from a first closed position wherein the mounting holes in the plate are aligned with mounting holes in the forging to a second open position.

    摘要: A system for blending polymers and other chemicals in an aqueous liquid is provided. Static mixers and tubes, preferably in one or more tube bundles, provide a volume sufficient to allow a residence time in the system to hydrate a polymer. Static mixers may be integrated with a tube bundle. The system may be mounted on a portable base such as a trailer. The concentration of polymer and chemicals in water may be controlled by a controller. A variable speed electric pump may be utilized to precisely control the amount of polymers or other chemicals added to the aqueous liquid.

    摘要: A single trip multizone time progressive well treating method and apparatus that provides a means to progressively stimulate individual zones through a cased or open hole well bore. This system allows the operator to use pre-set timing devices to progressively treat each zone up the hole. At each zone the system automatically opens a sliding sleeve and closes a frangible flapper, at a pre-selected point in time. An adjustable preset timing device is installed in each zone to allow preplanned continual frac operations for all zones. The apparatus is present as a “Frac Module” that can consist of three major components, a packer, a timing pressure device, and a sliding sleeve/isolation device. A hydraulic packer may be removed or replaced with a swellable type packer.

    摘要: Energy is stored by injecting fluid into a hydraulic fracture in the earth and producing the fluid hack while recovering power. The method is particularly adapted to storage of large amounts of energy such as in grid-scale electric energy systems. The hydraulic fracture may be formed and treated with resin so as to limit fluid loss and to increase propagation pressure.
