Abstract: A cannula tubing having a series of apertures at its distal end, so that the end of the tube is not the only egress point for the payload of the cannula. The cannula tubing is affixed to a base, which is configured to accept an input connector on the end opposing the cannula. The base is configured so that input medication from the connector flows down the cannula. The base is affixed to the patient via adhesive. The perforated cannula distributes the dose of the medication across a wider area. This has been demonstrated to increase uptake rate of some medications (reducing the time to peak absorption rate). Administering medication (such as insulin) over a greater area may lessen unwanted side effects of subcutaneous injecting, such as lipohypertrophy, scarring, or localized drug resistance.

Abstract: In a method for controlling the interface level between a liquid inventory and an overlying steam chamber in a subterranean petroleum-bearing formation, an inflow relationship is developed to predict the vertical position in a gravity field of the interface between two fluids with a density contrast (most commonly a water/oil emulsion and steam), relative to a horizontal producer well. The inflow relationship is applied to producer well completions by designing the completion to raise or lower sand face pressures over the horizontal length of the well. This pressure distribution will affect liquid levels according to the inflow relationship. Axial flow relationships for the liquid inventory may be developed to facilitate estimation of liquid levels at selected locations. Axial flow relationships for the steam chamber may also be developed to estimate the effect of the injector well completion on the steam chamber pressure and, in turn, the liquid level.

Abstract: In a method for controlling interface level between a liquid inventory and an overlying steam chamber in a subterranean petroleum-bearing formation, an inflow relationship is developed to predict the vertical position in a gravity field of the interface between the two fluids (liquid and steam) with a density contrast relative to a horizontal producer well. The inflow relationship is applied to producer well completions by designing the completion to raise or lower sand face pressures according to mobility variations over the horizontal length of the well. This pressure distribution will affect liquid levels according to the inflow relationship. The completion can include tubing-conveyed or liner-conveyed flow control devices to create flow network that provides a customized sand face pressure distribution. Axial flow relationships between adjacent locations along the producer well may be modeled in order to develop an axial flow network to facilitate estimation of liquid levels at selected locations.

Abstract: A system and method for detecting target rectangles in an image acquired from a camera or computer file in which average pixel values from small horizontal and vertical rectangles called sub-exlons are computed from an edge-detected and binarized version of the image. The sub-exlons are then used to scan for exlons, which are combinations of horizontal and vertical sub-exlons that make up the four possible types of corner (upper left, upper right, lower left, and lower right). Possible corners that are located are then matched up and a rectangle is confirmed by scanning for properly oriented horizontal and vertical connecting lines composed from the previously computed sub-exlons. All confirmed rectangles are stored in an array of found rectangles, which is then processed to filter out rectangles of the wrong aspect ratio.

Abstract: A method for distributing injection fluid in a horizontal well bore in fluid communication with hydrocarbon bearing formation begins by determining flow resistance characteristics of the formation along at least a portion of the length of the horizontal well bore. An injection tubing string having a sidewall defining a tubing bore is injected into the horizontal well bore. The tubing string is provided with ports having a selected distribution and geometry. The annulus geometry is selectively controlled along the length of the tubing string through at least one of axial distribution of eccentricity and flow area of the annulus, so as to provide selected flow restriction characteristics along the annulus, such that when injection fluid is pumped into the tubing, a resulting flow resistance network is formed by the tubing bore, the ports, the annulus and the formation, resulting in a desired distribution of the fluid into the formation.

Abstract: An apparatus for handling tubular goods which includes an elongate tubular body having a peripheral sidewall and opposed ends. The peripheral sidewall has a plurality of axial slots arranged circumferentially around the tubular body parallel to an axis of the tubular body. An articulating coupling protrudes from at least one of the opposed ends. The articulated coupling includes an insert positioned within the tubular body with radial pins that engage the slots, the pins being axially movable along the slots. A gripping assembly is provided at one of the opposed ends for engaging a tubular good.

Abstract: An apparatus for handling tubular goods which includes an elongate body having a coupling end adapted for mating engagement with a tubular good. The coupling end includes a structural member, a flexible cylindrical cage and a pressure member. Longitudinal strips joined at their opposed ends form the cage coaxial with and connected to the structural member of the body. The coaxial pressure member is disposed in an annulus between the structural member and the cage. The pressure member is adapted to cause radial displacement of the cage, thereby exerting a gripping force to maintain the mating engagement between the tubular good and the coupling end enabling a transfer of force between the body and the tubular good.

Abstract: A method for preparing casing for use in a wellbore such as for example, in preparation, for use to line a borehole through a formation or to act as a drill string and thereafter to remain in hole. In the method, a device supporting the use of the wellbore casing is crimped onto the outer surface of the casing. The device supporting casing use can be to facilitate run in through the borehole, to maintain positioning relative to the borehole, to accommodate wear against the wall of the borehole into which the casing is run or to enhance the results of cementing. The devices supporting the use of the casing are attached by crimping to the casing to create a connection having structurally significant axial and torque load transfer capacity.

Abstract: A plurality of steel rings are crimped or shrink fitted onto a joint of steel well casing to produce the casing anchor. The rings and joint are sufficiently interlocked so that, when the anchor is cemented in a well, the joint can transfer axial load from the casing string to the cement through the rings to provide resistance to axial displacement of the anchor relative to the surrounding earth material.

Abstract: A process for the high-yield recovery of ethylene and heavier hydrocarbons from the gas produced by pyrolysis of hydrocarbons in which the liquid products resulting from the fractionated condensation of a cracking gas for the recovery of almost all the ethylene, are supplied to a distillation column, called a de-ethanizer, at different intermediate levels. At the top of the de-ethanizer the vapor of the column distillate is treated directly in an acetylene hydrogenation reactor, the effluent containing virtually no acetylene being separated by a distillation column called a de-methanizer, into an ethylene- and ethane-enriched tail product, while the head product is recycled by compression or treated for subsequent recovery of ethylene.
