Appl. No.:

10/723290

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 19/16

US Classification:

16625001, 166 66, 166 7551, 166 781, 166380

Abstract:

A method and apparatus for connecting threaded members while ensuring that a proper connection is made. In one embodiment, the applied torque and/or rotation are measured at regular intervals throughout a pipe connection makeup. When a shoulder contact is detected, a predetermined torque value and/or rotation value is added to the measured torque and/or rotation values, respectively, at shoulder contact and rotation continued until this calculated value(s) is reached.

US Classification:

16625001, 166 66, 166 7751, 166380, 2940703

Abstract:

The present invention generally provides methods and apparatus for connecting threaded members while ensuring that a proper connection is made, particularly for premium grade connections. In one embodiment, a method of connecting threaded tubular members for use in a wellbore or a riser system is provided. The method includes the acts of operating a power drive unit, thereby rotating a first threaded tubular member relative to a second threaded tubular member; measuring the rotation of the first threaded tubular member; and compensating the rotation measurement by subtracting a deflection of at least one of: the power drive unit, and one of the tubular members.

Abstract:

An electrolyzer assembly has an outer, cylindrical dielectric electrolyzer housing member having a top, bottom, and cylindrical side wall. In one embodiment, the housing member has a sealed top, an open bottom for electrolyte entry, and apertures through the side wall near the sealed top permitting flow of electrolyte through the apertures. A cylindrical anode and cathode pair is situated inside the housing member. The cathode is positioned concentrically within the anode. Electrolyte flows in the space between anode and cathode. The anode is spaced apart from the side wall, providing an electrolyte flow path through the resulting cylindrically-shaped space. Electrical connections through the top of the housing member extend downwardly therein to electrical connection elements projecting upwardly from the electrode pair. The assembly provides for ease of cleaning, as well as ease of refurbishing, and operates efficiently and economically in both forced and unforced flow conditions.
