Filed:

Nov 14, 2007

Appl. No.:

11/940045

Inventors:

Jeffrey James Arcement - Houston TX, US
John E. Hebert - Houma LA, US
William L. Brunet - Houma LA, US
Joseph J. Boudreaux - Houma LA, US

International Classification:

E21B 33/14

US Classification:

166285, 1662428

Abstract:

A method and apparatus for cementing an annulus wellbore is described herein. The apparatus includes an internally radiused portion of a sleeve adapted for increasing the compressive strength of a compound for securing a valve in the sleeve. The internally radiused portion prevents the apparatus from leaking during operation. The apparatus is manufactured using one pass of a milling tool. The apparatus is run into a wellbore. A cementing operation in performed past the apparatus. The apparatus then prevents the cement from entering a downhole tubular.

International Classification:

E21B 19/24

US Classification:

166381, 1662411, 29428

Abstract:

A centralizer assembly having a tubular body member with upper and lower channels extending around the external surface of said central tubular body member. A bow spring assembly having bow spring members is installed around the outer surface of the tubular body member and can rotate about the outer surface of the central tubular body member. Bow spring heel supports prevent the bow spring members from contacting the outer surface of the central tubular member when compressed. Non-abrasive materials prevent damage to wellhead or other polished bore receptacles. A robust bolster frame protects the centralizer assembly during shipping, storage or other periods of non-use.

International Classification:

E21B 23/00

US Classification:

166381, 166 53

Abstract:

An apparatus for launching objects, such as during casing cementing operations, in wells having dual gradient fluid systems or certain downhole internal diameter restrictions. A launching assembly is located below a dual gradient valve or other restriction. In one embodiment, control lines extend from the earth's surface to the launching assembly and control actuation of the launching assembly. In an alternative embodiment, a receptacle assembly is positioned above a dual gradient valve or other restriction, with control lines extending from the receptacle assembly to the launching assembly. A dart or other triggering object is launched from the earth's surface to the receptacle assembly in order to control actuation of the launching assembly.

Abstract:

A connection assembly for automated lifting and positioning of a chiksan or other fluid conduit in proximity to a fluid inlet of a device such as, for example, a cement or hydraulic fracturing head. Once a chiksan or other flow line is positioned in a desired location, a secure connection is made between the outlet of the chiksan or other fluid conduit and the fluid inlet including, without limitation, when the device is positioned at an elevated location above a rig floor.
