  • Publication number: 20110094746
    Abstract: In some embodiments, the invention provides methods useful for subterranean operations, and more particularly, to swellable spacer fluids for sealing an annular space in a well bore, such as the annular space between a tubular and the subterranean formation or between two concentric tubulars or for forming a seal inside a well bore in the subterranean formation. One method involves providing a swellable fluid, wherein the swellable fluid comprises: an aqueous fluid, a crosslinking agent, and at least a plurality of swellable particles; and placing the swellable fluid in a subterranean formation, and allowing the spacer fluid to form a semi-solid crosslinked gel structure in the subterranean formation.

  • Publication number: 20110094748
    Abstract: An automatic release system for a riser includes a guide funnel assembly that receives a shaft coupled to the riser. A pull-head is located inside at least a portion of the shaft and coupled to the shaft. The pull-head is coupled to a pulling mechanism. One or more spring-loaded dogs are mounted on the outside of the shaft. The dogs radially move in and out through one or more openings in the shaft aligned with the dogs and engage a groove on the pull-head when radially moved in through the openings. One or more stopper mechanisms are mounted on the outside of the shaft and aligned with the dogs. In a first position, the stopper mechanisms inhibit the dogs from disengaging from the groove in the pull-head. In a second position, the stopper mechanisms allow the dogs to disengage from the groove in the pull-head.

  • Publication number: 20110094752
    Abstract: A well installation including metallic structure having downhole metallic tubing for conveying product towards the surface, a sub surface safety valve disposed in the downhole metallic tubing for interrupting flow of product towards the surface when closed and allowing flow of product towards the surface when open. Also, valve control means are disposed downhole and arranged for detecting electrical signals in the downhole metallic tubing and for holding the valve open while receiving an electrical signal, and surface signaling means for applying an electrical signal to metallic structure of the well for transmission via the downhole metallic tubing towards the valve control means so as to hold the valve open. The system can be made more robust by ensuring that the control means will only hold the valve open while receiving a signal of given characteristics to help prevent stray currents erroneously holding the valve open.

  • Publication number: 20110094753
    Abstract: A downhole releasable tubing connection includes a joint between two tubing strings, wherein one of the two tubing strings is radially expanded and plastically deformed by an expansion device. When the expansion device is moved adjacent to the joint, a mechanism in the joint reacts to the radially outward forces of the expansion device and releasably expands, separates, breaks, or otherwise provides a release between the two tubing strings. One tubing string and the expansion device can then be removed to the surface of the well bore while the expanded tubing remains installed in the well bore.

    Abstract: The present invention is directed to systems and methods for initiating annular obstructions in wells used in, or in support of, enhanced oil recovery operations—particularly enhanced oil recovery (EOR) efforts involving steam injection (e.g., steam flooding). In at least some instances, system and method embodiments of the present invention utilize one or more passively-activated annular obstruction devices (and/or hybrid active/passive devices) for inducing annular obstruction, wherein the associated passive or hybrid activation is at least partially controlled by thermal means such that it can be deemed to be thermally-directed or thermally-controlled. Such thermally-directed passive activation can afford considerably more control over the annular obstruction process and, correspondingly, over the overall steam injection into the formation and associated reservoir—thereby providing more efficient recovery of hydrocarbons.

    Abstract: An electric power tool has a drive motor and an electronic control unit. Power is supplied by a battery pack with several individual cells and a monitoring circuit for the operating parameters of the cells. A communication line connects electronic control unit and monitoring circuit. Digital data are exchanged through the communication line between electronic control unit and monitoring circuit. A controller controls data traffic through sending and receiving units. The communication voltage is higher than a permissible input voltage level of the controller and lower than a maximum battery pack voltage. The receiving unit, as a filter, converts a received first signal level that is lower than a first voltage to a LOW signal and lowers a received second signal level that is higher than a second voltage to the input voltage level of the controller and relays the second signal level as a HIGH signal.

    Abstract: A printed circuit board includes a signal plane and a reference plane. The signal plane includes a pad, a passive element mounted on the pad, and a signal transmission line electrically connected to the passive element via the pad. The reference plane provides a return path for a signal transmitted through the passive element and the signal transmission line. A void is defined in the reference plane corresponding to the passive element, to increase a length of the return path. A length of a first axis, perpendicular to the signal transmission line, of the void satisfies a following equation: W 1 ? 8 ? Wpad + 10 ? T 0.8 ? Wtrace + T , wherein Wpad is a width of the pad, Wtrace is a width of the transmission line, T is the height of the pad.
