Torque Limiting Device
US Patent:
2013014, Jun 6, 2013
Filed:
Nov 27, 2012
Appl. No.:
13/686564
Inventors:
Michael Keith Sullivan - Katy TX, US

International Classification:
E21B 17/02
US Classification:
1663051, 1662426, 166 99, 166380
Abstract:
A work string assembly for an oil or gas well has a first and second tubulars, and a torque limiting device connected in the work string. The torque limiting device has a body with an axial bore and two interconnected members that can disconnect to be relatively rotatable. The interconnected members can be repeatedly re-engageable when the torque levels drop below a torque threshold value, or can be connected by a frangible member that is broken when the interconnected members disconnect. A selectively actuable circulation port provided in the string adjacent to and above the torque limiting device allows the annulus between the work string and the casing to be flushed with fluid from the port.
Flexible Wellbore Broach

Assignee:
Weatherford/Lamb, Inc. - Houston TX
International Classification:
E21B 29/10
US Classification:
166298, 166 557
Abstract:
A method and apparatus for milling and/or broaching within a wellbore. A flexible broach runs into the wellbore and is located adjacent a portion of the wellbore to be broached. The broach reciprocates axially within the wellbore and removes at least part of the portion to be broached. Weight may be coupled to the broach, thereby applying a resultant side load for broaching an offset portion of the wellbore. The broach comprises a flexible member that may be a bare cable. When an abrasive material is disposed on an outer surface of the flexible member, the flexible member may be a cable, a continuous rod, or pressurized coiled tubing. Alternatively, sleeves positioned on the flexible member may have an abrasive material on their outer surface. A rotational mill that is either coupled to the broach or run in separately from the broach can further mill the wellbore.
