Appl. No.:

09/995842

Inventors:

John E. Hebert - Houma LA
Joseph J. Boudreaux - Houma LA
David F. Laurel - Cypress TX
Scott A. Darby - Houston TX

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 3400

US Classification:

166374, 166325, 166326, 1375157

Abstract:

The present invention generally relates to a flow-actuated valve for use in a wellbore. The invention includes a body having a closing member and a seat. The closing member and seat are separable to open and close the valve, thereby allowing the flow of fluid through the valve. The invention further includes a retainer to initially retain the valve in the open position absent a predetermined fluid flow rate in a first direction for a predetermined time period. A biasing member thereafter urges the valve to the closed position, absent another fluid flow rate in the first direction.

International Classification:

E21B 4310

US Classification:

166285, 166207, 166380

Abstract:

The present invention provides a cement shoe assembly for use on a string of tubulars in a well. In one aspect of the invention, the cement shoe assembly includes a housing having a lower portion with an enlarged inside diameter and a drillable cement shoe disposed therein. The shoe includes a weakened portion of material adjacent the enlarged inside diameter portion of the housing and ensures that as a cutting tool passes through the housing, all portions of the cement shoe are removed from the enlarged inside diameter portion, leaving a connection surface clear of debris for a subsequent tubular string. When a smaller tubular is expanded into the enclosed diameter portion of the housing, a connection is made therebetween without enlarging the outer diameter of the housing.

Joshua T. Smith - Spring TX, US

International Classification:

E21B 34/06

US Classification:

166373, 166321

Abstract:

A method and apparatus for a pressure relief valve assembly. The valve assembly may be coupled to one or more casings and/or tubular members to control fluid communication therebetween. The valve assembly is a one-way valve assembly that relieves pressure within an annulus formed between adjacent casings and/or tubular members to prevent burst or collapse of the casings and/or tubular members. The valve assembly is resettable downhole.

International Classification:

E21B 17/10
E21B 19/00

Abstract:

A centralizer assembly installed on a casing section. A bow spring assembly having bow spring members is installed around the outer surface of the casing section and can rotate about the outer surface of the casing section. A portion of the casing section that is aligned with the bow spring assembly is swaged to increase the outer diameter of that section. Bow spring heel supports prevent bow spring members from contacting the outer surface of the central casing section when compressed. Non-abrasive materials prevent damage to wellhead or other polished bore receptacles.

International Classification:

E21B 19/00
E21B 19/22

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 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 of a cement head including, without limitation, when the cement head is positioned at an elevated location above a rig floor.
