Abstract:

The present invention generally relates to methods and apparatus for subsea well intervention operations, including retrieval of a wellhead from a subsea well. In one aspect, a method of performing an operation in a subsea well is provided. The method comprising the step of positioning a tool proximate a subsea wellhead. The tool has at least one grip member and the tool is attached to a downhole assembly. The method also comprising the step of clamping the tool to the subsea wellhead by moving the at least one grip member into engagement with a profile on the subsea wellhead. The method further comprising the step of applying an upward force to the tool thereby enhancing the grip between the grip member and the profile on the subsea wellhead. Additionally, the method comprising the step of performing the operation in the subsea well by utilizing the downhole assembly. In another aspect, an apparatus for use in a subsea well is provided.

US Classification:

166298, 166 553

Abstract:

A method for milling a tubular cemented in a wellbore includes deploying a bottomhole assembly (BHA) into the wellbore through the tubular, the BHA comprising a window mill; and extending arms of the window mill and radially cutting through the tubular, thereby forming a window through the tubular, wherein a body portion of each window mill arm engages and stabilizes from an inner surface of the tubular after a blade portion of each window mill arm cuts through the tubular.

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 2900

US Classification:

166298

Abstract:

A system has been invented for cutting wellbore casing and retrieving casing and a wellbore device connected thereto, the system, in one aspect, including engaging apparatus for releasably holding the wellbore device, casing cutting apparatus interconnected with and below the engaging apparatus for cutting casing in a wellbore, the wellbore device connected to the casing, and locking apparatus for selectively and releasably locking the engaging apparatus holding the wellbore device. In one aspect the engaging apparatus has one or more movable latching arms for releasably holding a wellbore device, e. g. but not limited to a wellhead and the arms are mounted below a top bonnet that holes therethrough so that the flushing of debris and/or cutting from the tops of the arms is facilitated. In one aspect, a drain sub is used to reduce flow to the casing cutter so that the circulation of debris and/or cuttings is inhibited.

E21B 33/13
E21B 47/09

Abstract:

A mill for use in a wellbore includes a tubular housing having a bore therethrough and a plurality of eccentrically arranged pockets formed in a wall thereof and an arm disposed in each pocket. Each arm has a body portion and a blade portion extending from an outer surface of the body portion and is movable between an extended position and a retracted position. The mill further includes cutters disposed along each blade portion and a block disposed in each pocket and connected to the housing. Each block has a guide engaged with a mating guide of the respective body portion and an inner passage for providing fluid communication between the housing bore and the respective pocket. The mill further includes an actuator for extending the arms.

International Classification:

E21B 29/00
E21B 17/10
E21B 29/06

Abstract:

A method of cutting a tubular includes disposing a rotatable cutter assembly in the tubular, the cutter assembly including a blade having a cutting portion; engaging the tubular using a trailing cutting structure of the cutting portion; engaging the tubular using an intermediate cutting structure of the cutting portion; forming a window in the tubular; and longitudinally extending the window using a leading cutting structure of the cutting portion. A rotatable blade includes a blade body extendable from a retracted position; and a cutting portion on the blade body having: a trailing cutting structure configured to engage the tubular, an intermediate cutting structure configured to engage the tubular while the trailing cutting structure engages the tubular, a leading cutting structure configured to engage an exposed wall thickness of the tubular; and an integral stabilizer disposed on at least a portion of an outer surface of the blade body.

Thomas D. Helbert - Magnolia TX, US

International Classification:

E21B 31/00
E21B 23/00

Abstract:

A pulling tool deploys on a workstring to retrieving a well component, such as casing or a liner, stuck downhole. The tool has an anchor, a puller, and an implement. The implement is supported on the end of the puller and engages the component. Hydraulic pressure supplied downhole moves at least one puller piston coupled to the implement along a piston mandrel to pull the implement and component. An anchor mandrel coupled to the workstring and the piston mandrel anchors the pulling tool downhole. The anchor has slips disposed on the anchor mandrel that engage in surrounding casing when an anchor piston disposed on the anchor mandrel is hydraulically actuated with the communicated pressure.
