Assignee:

Mandrels, Inc. - Houston TX

International Classification:

E21B 1710
E21B 1718

US Classification:

166242

Abstract:

An insert for use in a mandrel used in the production string of a well utilizing a gas lift operation is disclosed. The tubing unit and the valve lug forming the mandrel have communicating bores into which the insert, which is formed of an abrasion resistant material such as carbide, is placed. The insert is soldered in place, with the soldering to the valve lug being accomplished through a temporary opening in the valve lug. A method for assembly of the mandrel is described and an abrasion resistant sleeve for inclusion in a valve lug for use with a fluid operated valve is disclosed.

International Classification:

E21B 17/042
F16L 57/00
F16L 15/08

Abstract:

Herein disclosed is a method of protecting a tubular or a component attached to the tubular, comprising making two sections of the expandable tubular into two complete centralizing rings or two partial centralizing rings having a larger outer diameter than the remainder of the expandable tubular, wherein the two complete centralizing rings or partial centralizing rings are on two ends of the component. Also discussed herein is an assembly comprising an expandable tubular, a component attached to the tubular, a sleeve over the component and an adhesive; wherein the adhesive fully covers the space between the inside diameter of the sleeve and the outside diameter of the component. The sleeve remains in place when the tubular is placed down hole. Related methods and assemblies are discussed in further details.

International Classification:

E21B 43/10
B21D 39/20

Abstract:

Herein disclosed is an expansion device comprising at least one expanding segment; an actuator; and a connector linking the at least one expanding segment to the actuator such that when the actuator is activated, the expanding segment expands or retracts. The actuator is propelled by hydraulic, pneumatic, or electric power. Also disclosed herein is a method expanding a portion of a tubular comprising providing an expansion device comprising at least one expanding segment, an actuator, and a connector linking the at least one expanding segment to the actuator such that when the actuator is activated, the expanding segment expands or retracts; and placing the at least one expanding segment inside the tubular.

International Classification:

E21B 43/10
E21B 19/24
E21B 17/10

Abstract:

Herein disclosed is an apparatus comprising an expandable tubular; and at least one section of the expandable tubular having a larger outer diameter than the remainder of the expandable tubular, forming at least one complete centralizing ring or at least one partial centralizing ring. In an embodiment, at least one complete centralizing ring or at least one partial centralizing ring is configured to centralize the expandable tubular when the tubular is in use; and wherein at least one complete centralizing ring or at least one partial centralizing ring has the same diameter as the expandable tubular after the tubular is radially expanded. Also disclosed herein are method of using and method of making the apparatus.
