  • Patent number: 9045956
    Abstract: In one aspect, a method of method of performing a wellbore operation is disclosed that in one embodiment may include: providing a device that includes a non-explosive energetic material configured to disintegrate when subjected to a selected energy; placing the device at a selected location in the wellbore to perform a selected function; and subjecting the device to the selected energy to disintegrate the device in the wellbore after the device has performed the selected function. In another aspect an apparatus for use in a wellbore is disclosed that in one embodiment may include a device placed in the wellbore at a selected location, wherein the device includes a non-explosive energetic material configured to disintegrate when subjected to a selected energy, and a source of the selected energy configured to subject the device to the selected energy in the wellbore to disintegrate the device.

  • Patent number: 8939221
    Abstract: A lock assembly including a mandrel having one or more windows arranged alternatingly with one or more struts. One or more dogs are included corresponding to the one or more windows and are radially extendable therethrough. A member is operatively arranged for radially extending each of the one or more dogs. Each of the one or more dogs is operatively coupled between the member and the mandrel when fully radially extended by the member for bypassing loading in the one or more struts during loading of the assembly.

  • Patent number: 8607860
    Abstract: A collet assembly has a housing and the collets disposed on flexible fingers connected to the housing at their opposed ends. A surrounding landing sleeve stops the assembly so that collets are aligned with a recess in a landing collar that is part of a surrounding tubing string. Once set the landing sleeve transmits compressive loads so that compressive stress essentially bypasses the finger structure supporting the collets. The fingers are initially tapered toward a longitudinal axis so that when internally supported they assume an aligned orientation to the housing axis to allow greater tensile loading and to provide a retraction force when the housing is to be removed after the collet support is removed.

  • Publication number: 20130175051
    Abstract: A lock assembly including a mandrel having at least one window therein. At least one dog corresponds to the at least one window and is radially extendable therethrough. The at least one dog is operatively arranged for engaging at least one feature of a tubular radially disposed with the mandrel. At least one seal element is arranged for sealing the mandrel with respect to the tubular and operatively positioned with respect to the at least one dog for maintaining the mandrel solely in compression against the at least one dog during fluid pressure loading on the mandrel in either longitudinal direction with respect to the lock assembly.

  • Patent number: 8291982
    Abstract: A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves that can assume at least two configurations: wide open and open with a screen material juxtaposed in the flow passage. In a preferred embodiment the valve assembly has three positions, adding a fully closed position to the other two mentioned. After run in, the valves can be put in the wide open position in any order desired to fracture. After fracturing, the valves can be closed or selectively be put in filtration position for production from the fractured zones in any desired order. Various ways are described to actuate the valves. The tubular can have telescoping pistons through which the fracturing can take place if the application calls for a cemented tubular.
