Abstract
A device is provided for positively locating within a profile, wherein the device includes one or more radially resilient locator mechanisms; one or more slips; one or more packing elements; and a stopping mechanism; wherein the one or more locator mechanisms are radially expandable to locate within the profile and wherein the stopping mechanism prevents engagement of the one or more slips and the one or more packing elements unit the one or more locator mechanisms are located in the profile. A method is also provided for applying downhole isolation.
Claims13
A method for applying downhole isolation, said method comprising the steps of:
- a. running an intervention tool downhole to a first downhole location, the intervention tool comprising:
- an inner mandrel, the inner mandrel further comprising:
- an outer mandrel surface;
- a locator support integral with the outer mandrel surface, the locator support configured with an outer planar surface;
- and
- an end shoulder,
- a drag assembly slidably movable around the inner mandrel, the drag assembly further comprising:
- a first radial inner end slidably engaged with the outer mandrel surface;
- a second radial inner end slidably engaged with the outer mandrel surface;
- an at least one locator mechanism disposed between the first radial inner end and the second radial inner end;
- a slip disposed around the inner mandrel;
- a cone disposed around the inner mandrel;
- and
- a packing element disposed around the inner mandrel, and also disposed between the end shoulder and the cone
- b. locating the at least one locator mechanism into an external profile by shifting the intervention tool axially;
- c. engaging the packing element with a surrounding surface by shifting the intervention tool axially, while the at least one locator mechanism is located within the external profile;
- d. disengaging the packing element by shifting the intervention tool axially;
- and
- e. moving the intervention tool to another downhole location.
An intervention tool for positively locating within a profile, the intervention tool comprising:
- an inner mandrel, the inner mandrel further comprising:
- an outer mandrel surface;
- a locator support integral with the outer mandrel surface, the locator support configured with an outer planar surface;
- and
- an end shoulder,
- a drag assembly slidably movable around the inner mandrel, the drag assembly further comprising:
- a first radial inner end slidably engaged with the outer mandrel surface;
- a second radial inner end slidably engaged with the outer mandrel surface;
- an at least one locator mechanism disposed between the first radial inner end and the second radial inner end;
- a slip disposed around the inner mandrel;
- a cone disposed around the inner mandrel;
- a packing element disposed around the inner mandrel, and also disposed between the end shoulder and the cone,
- wherein the intervention tool comprises an unset and set position, wherein the set position comprises the at least one locator mechanism is located in the profile, and the outer planar surface engaged with the at least one locator mechanism.
An intervention tool for positively locating within a profile, the intervention tool comprising:
- an inner mandrel, the inner mandrel further comprising:
- an outer mandrel surface;
- a locator support integral with, and protruding outward from, the outer mandrel surface, the locator support configured with an outer planar surface;
- and
- an end shoulder,
- a drag assembly movable around the inner mandrel, the drag assembly further comprising:
- a first radial inner end movably engaged with the outer mandrel surface;
- a second radial inner end movably engaged with the outer mandrel surface;
- an at least one locator mechanism disposed between the first radial inner end and the second radial inner end;
- a slip disposed around the inner mandrel;
- a cone disposed around the inner mandrel;
- a packing element disposed around the inner mandrel, and also disposed between, and
- engaged with, each of the end shoulder and the cone,
- wherein the intervention tool comprises an unset and set position, wherein the set position comprises the at least one locator mechanism located in the profile, and the outer planar surface engaged with an underside of the at least one locator mechanism.
