| 20110062670 | LOAD DELAYED SEAL ELEMENT, SYSTEM, AND METHOD - A seal assembly including, a deformable force transmission portion having an inner surface and an outer surface, the force transmission portion operative to transmit an applied force to a component linked to the seal assembly, and deformable in a direction transverse to a main axis of the seal assembly in response to a increased applied force greater than a threshold setting force, and a flexible outer seal portion attached to the outer surface and method. | 03-17-2011 |
| 20110186286 | One Trip Retrieval of a Multi-zone Fracturing System - A completion assembly of a top packer and zone isolation packers separated by screens has a disconnect in a selected zone to be fractured or gravel packed that is armed before such a procedure starts. Initially when the assembly of the outer completion and the inner string are properly located and all the screens valved off, all the packers are pressure set and the packer set release device associated with each packer is armed. Before starting a fracturing or gravel packing operation from a given zone isolation packer, a disconnect for that zone packer is armed so that if the inner string sticks in that packer, the inner string is sheared and removed and another trip is used to grab the top packer and pick up. Such picking up releases all the packers down to the one armed disconnect. The disconnect releases bringing up the remnant of the inner string stuck in the packer just above the actuated disconnect. | 08-04-2011 |
| 20120186824 | SELECTIVE SLEEVE SYSTEM AND METHOD OF MOVING A SLEEVE - A selective sleeve system includes, a tubular, a sleeve movably disposed at the tubular, and a movable member having at least one dog radially biased and configured to be radially displaceable into a recess. The at least one dog is positionable perimetrically adjacent to at least one tab, subsequent displacement into the recess to radially overlap with the sleeve sufficiently to move the sleeve relative to the tubular upon movement of the movable member relative to the tubular. | 07-26-2012 |
| 20130140041 | SELECTIVELY DISENGAGABLE SEALING SYSTEM - A seal assembly including a first tubular having a sealing surface and a seal element run with the first tubular and displaced from the surface. The seal element initially has a radial dimension that forms a radially innermost or outermost sealing dimension of the first tubular for enabling the first tubular to be sealed with a second tubular radially disposed with the first tubular. A mechanism is included that is triggerable for reconfiguring the radial dimension of the seal element. The sealing surface of the first tubular operative forms the radially innermost or outermost sealing dimension of the first tubular when the radial dimension of the seal element has been reconfigured for enabling the sealing surface of the first tubular to receive a second seal element. A method of sealing tubulars is also disclosed. | 06-06-2013 |
| 20140008052 | Resettable Selective Locking Device - A collet system is disabled from gaining profile support when moved between profiles that will be used ultimately to support an inner string at a desired plurality of locations. It is when the collet reaches a desired location that it is unlocked by virtue of inner string movement so that a profile on the outer assembly is engaged by a sleeve to induce relative rotation of the sleeve with respect to the mandrel that supports the sleeve. The relative rotation moves a tab into alignment with a slot to permit relative axial movement between the mandrel and the tool so that the tool can function as intended. The sleeve is engaged by another profile for further relative rotation to misalign the tab and the slot to lock the tool. The tool is preferably a support collet for a crossover in a multi-zone gravel pack. | 01-09-2014 |
| 20140014347 | FORMATION TREATMENT SYSTEM - A treatment system including a first tubular having at least one port therein. A valve member is disposed with the first tubular and operatively arranged to control fluid flow through the at least one port. A second tubular is disposed radially within the first tubular and terminates at an end opening into an interior passage of the first tubular for enabling a treatment media to be supplied through the second tubular into the first tubular, and through the at least one port when the at least one port is open. A seal assembly is disposed between the first and second tubulars for fluidly sealing an annulus formed between the first and second tubulars from the end of the second tubular. A tool is disposed with the second tubular for controlling operation of the valve member. | 01-16-2014 |
| 20150075788 | Apparatus and Methods for Locating a Particular Location in a Wellbore for Performing a Wellbore Operation - An apparatus for use in a wellbore is disclosed that in one non-limiting embodiment includes a locating device having a locating collet configured to engage with a locating profile on a housing and disengage from the locating profile when a first pull load is applied to the locating collet, a delay device that prevents application of the first pull load on the locating collet when it is engaged with the locating profile until the delay device has been activated, and a locking device configured to prevent activation of the delay device until a second pull load less than the first is applied on the locking device for a selected period of time. | 03-19-2015 |
| 20150075800 | Flow-Activated Flow Control Device and Method of Using Same in Wellbores - A flow control device for use in a wellbore is disclosed that in one non-limiting embodiment may include a main flow passage and a weep hole, wherein the main flow passage closes when a fluid is supplied to a first end of the valve that exceeds a selected rate and opens when the fluid supplied is below the selected rate and wherein the weep hole continues to allow the fluid therethrough. | 03-19-2015 |
| 20150075807 | Apparatus and Methods for Selectively Treating Production Zones - In one aspect, an apparatus for selectively treating a plurality of zones around wellbore is disclosed that in one non-limiting embodiment includes an outer string for placement in the wellbore, the outer string including a packer above a flow port corresponding to each zone, wherein each packer is configured to be set independently and the flow port is configured to supply a treatment fluid to its corresponding zone when such flow port is open, an activation device coupled to each packer, wherein each such activation device is configured to be independently activated to set its corresponding isolation packer, and an inner string for placement in the outer string, the inner string including a frac port for supplying a fluid under pressure to each flow port. | 03-19-2015 |
| 20150075815 | Apparatus and Methods Setting a String at Particular Locations in a Wellbore for Performing a Wellbore Operation - An apparatus for use in a wellbore is disclosed that in one non-limiting embodiment includes a set down tool that includes a locating device configured to engage with an outer member at a selected location, a set down device configured to set down in a set down profile in the outer member when the set down device is activated, an alignment device for activating the set down device and a locking device that operates the alignment device to activate the set down device while maintaining the locating device engaged with the outer member. | 03-19-2015 |
