Appl. No.:

09/734489

Inventors:

Patrick G. Maguire - Cypress TX
Richard Duff - Sherwood Park, CA
Tarald Gudmestad - Houston TX
Mark Murray - Sugar Land TX

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 3410

US Classification:

166386, 1662426

Abstract:

The present invention generally provides a running tool comprising a torque-dampening system. A first portion and a second portion of the running tool are operably related by a torsion interface. In one embodiment, the torsion interface includes a plurality of interlaced teeth disposed on the each of the first and second portions. During relative rotation of the first and second portions, the teeth engage and âride upâ on one another, thereby forcing the first and second portions in opposite axial directions. At least one of the portions houses a flow restrictor assembly adapted to restrict fluid flow from one region to another during the axial movement of the portions. Accordingly, the relative rotation between the portions is inhibited, or dampened.

US Classification:

166380, 166206, 166207

Abstract:

The present invention provides apparatus and methods for completing a wellbore using expandable tubulars. In one aspect, the invention includes a tubular member with an expandable portion at a lower end constructed and arranged to be expanded into contact with a previously expanded liner. At an upper end of the tubular is a polish bore receptacle permitting the tubular to be tied back to the surface of the well with production tubing. In another aspect, the invention provides a method of completing a well comprising expanding a liner top into a cased wellbore to hang the liner and, thereafter running a tubular member into the wellbore.

International Classification:

E21B 708

US Classification:

166 50, 1661176, 175 81, 175 82

Abstract:

The well reference apparatus and method of the present invention includes an anchor member with a orientation member preferably permanently installed within the borehole at a preferred depth and orientation in one trip into the well. The orientation member provides a permanent reference for the orientation of well operations, particularly in a multi-lateral well. The assembly of the present invention includes disposing the anchor member and orientation member on the end of a pipe string. An orienting tool such as an MWD collar is disposed in the pipe string above the anchor member. This assembly is lowered into the borehole on the pipe string. Once the preferred depth is attained, the MWD is activated to determine the orientation of the orientation member. If the orientation member is not oriented in the preferred direction, the pipe string is rotated to align the orientation member in the preferred direction. This process is repeated for further corrective action and to verify the proper orientation of the orientation member.

Mark Murray - Sugar Land TX

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 1916

US Classification:

166207, 166380

Abstract:

The present invention provides an apparatus and method expanding a portion of a tubular. The expansion apparatus is run into a wellbore on a working string. The expansion apparatus first comprises a rotary expander for expanding an expandable tubular. The expansion apparatus further comprises a spline assembly for coupling the rotary expander to a motor disposed on the work string. The rotary expander and spline assembly have hollow bodies that allow them to encircle the work string and rotate relative thereto. The spline assembly comprises an inner sleeve and outer sleeve. The inner sleeve is attached to the motor and the outer sleeve is attached to the rotary expander. The inner and outer sleeves are coupled to each other using a spline and groove connection. The connection allows the rotary expander to be rotated by the motor, while at the same time, allow the rotary expander to move axially relative to the motor. The rotary expander comprises two rows of rollers for expansion against the tubular.

US Classification:

285318, 285 92, 285305, 285333

Abstract:

A connector arrangement used for connecting and locking tubular members. The connector consists of two tubular members and a coupling member. The tubular members are threaded together to create a threaded connection. The locking arrangement is provided by a pathway formed on the tubular member whereby a locking member can be inserted in to the pathway to lock the threaded connection. The locking arrangement is also provided by a plurality of castellation members disposed on each tubular member. The connector also has a separate coupling member which has opposite right-hand and left-hand threaded ends to threadedly mate with the threads of the two tubular members.
