  • Publication number: 20070137822
    Abstract: A paper web is moved from an upstream source by a transport mechanism, and is cut into individual sheets of paper by a blade. The transport mechanism operates in a start-and-stop motion cycle to move the web intermittently. During the stop periods, the blade cuts the web. The transport mechanism includes a driving member, and also includes a driven member for performing a start-and-stop motion in response to simultaneous non-stop motion of the driving member. The driven member is arranged to cause the web to move to the blade, and each cutting occurs when the driven member is in a substantially stopped position. The interface between the driving member and the driven member is mechanical only.

  • Publication number: 20070137823
    Abstract: Temperature measurements of sheet material such as paper can be obtained directly from an analysis of the absorption spectrum of water in the infrared region. The technique is based in part on the recognition that the central wavelength position of a selected moisture peak is dependent upon the sheet temperature; the wavelength position also has a known temperature sensitivity. Thus, once the wavelength position of this moisture peak is ascertained, the moisture temperature of the product being monitored can be calculated. The position of the moisture peak is preferably obtained from the derivative of the peak. By measuring the size of the infrared absorption and the wavelength position of the absorption peak, both the moisture content and the moisture temperature of the sheet material can be determined. The data is used for process control. Tunable laser diodes are particularly suited as the source of infrared radiation for the temperature sensors.

  • Publication number: 20070137858
    Abstract: The extraction of hydrocarbon fuel products such as kerogen oil and gas from a body of fixed fossil fuels such as oil shale is accomplished by applying a combination of electrical energy and critical fluids with reactants and/or catalysts down a borehole to initiate a reaction of reactants in the critical fluids with kerogen in the oil shale thereby raising the temperatures to cause kerogen oil and gas products to be extracted as a vapor, liquid or dissolved in the critical fluids. The hydrocarbon fuel products of kerogen oil or shale oil and hydrocarbon gas are removed to the ground surface by a product return line. An RF generator provides electromagnetic energy, and the critical fluids include a combination of carbon dioxide (CO2), with reactants of nitrous oxide (N2O) or oxygen (O2).

  • Publication number: 20070137859
    Abstract: A laboratory test method employs maximum acoustic wave velocity to determine cure time of a sample of curable resin-coated proppant (CRCP) that are packed in a pressurized chamber to simulate conditions in a reservoir rock formation during fracturing in which the CRCP will be used. The pressurized CRCP is subjected to a varying temperature profile that replicates the reservoir temperature recovery during shut-in of the fractured zone in order to develop maximum proppant pack strength and minimize proppant flow back following completion of the fracturing operation and to determine shut-in time to complete curing of the resin.

    Abstract: Wellhead assembly and method for providing a power connection to a downhole electrical device, such as a heater. Pressure-containing wellhead body members enclose a vertical wellbore and support therein an isolated tubing hanger and a grounding tubing hanger. The isolated tubing hanger suspends a conducting tubing string, while the grounding tubing hanger suspends a grounding tubing string concentrically spaced from the conducting tubing string. The isolated tubing hanger has an outer housing, an inner electrically conducting portion supported by the outer housing operative to provide electrical connection with, and suspend, the conducting tubing string, and insulation between the housing and conducting portion to electrically isolate the housing portion. Hot electrical connection is made for electrical connection to the conducting portion of the isolated tubing hanger or the conducting tubing string.

  • Publication number: 20070137865
    Abstract: A setting mechanism is made to respond to hydrostatic pressure. Upon reaching a predetermined depth corresponding to a given pressure, a pilot piston is shifted to allow well fluids to bypass a first set of piston seals and reach a second set. A shear pin that held the pilot piston in position is broken as the hydrostatic pressure increases with greater depth attained. However, the shifting of the pilot piston does not cause the main piston in the assembly to set the downhole tool. The action of the well fluids on the secondary seal set on the pilot piston eventually fail the second seal set allowing hydrostatic pressure to bypass them and actuate the main piston that will set the downhole tool. Raising the tool from the wellbore allows the spring acting on the pilot piston to seal in a bore to isolate hydrostatic pressure from the operating piston.

  • Publication number: 20070137869
    Abstract: A subsurface safety valve comprises a tubular body adapted for placement within a wellbore and defining a fluid passageway. A valve closure member, such as a flapper valve, is carried by the tubular body and movable through a closure path between positions opening and closing the fluid passageway. An actuator, such as a biasing spring, urges the valve closure member to its closing position. A flow tube is axially-movable within the tubular body between a first position preventing the actuator from urging the valve closure member to its closing position and a second position permitting the actuator to urge the valve closure member to its closing position. A latch assembly is provided for preventing movement of the valve closure member from its opening position to its closing position until the flow tube has been urged clear of the closure path. Aspects of the safety valve are employed by a related method and system.
