Filed:

Mar 26, 1992

Appl. No.:

7/858100

Inventors:

John A. O'Donnell - Cypress TX
Richard W. Wilson - The Woodlands TX

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

B23P 1102

US Classification:

29447

Abstract:

A method is provided for securing a wellbore tool assembly to a wellbore tubular member, which includes a number of method steps. The wellbore tubular member is provided, and defines a surface with a substantially cylindrical shape having a selected tubular diameter. A wellbore tool assembly is likewise provided, and includes a plurality of ring-shaped components, with at least one ring-shaped component defining a cylindrical surface having a selected ring diameter which differs from the tubular diameter of the wellbore tubular member. A plurality of radial groove members and radial land members are formed on at least one of the cylindrical surface of the wellbore tubular member and the cylindrical surface of the at least one ring-shaped component of the wellbore tool assembly. The wellbore tubular member and the at least one ring-shaped component of the wellbore tool assembly are urged to differing thermal conditions to cause the tubular diameter and the ring diameter to become substantially equal. While maintaining the differing thermal conditions, the wellbore tubular member and the at least one ring-shaped component of the wellbore tool assembly are coupled together.

US Classification:

348143

Abstract:

A system and method is disclosed for instructing personnel in the operation and servicing of machinery at a plant from a geographically remote service center employing trained personnel. The system and method includes monitoring operating machinery at the plant with a video camera and transmitting a video signal to a base unit associated with the plant having a high resolution monitor. Audio communication is also provided between plant personnel and the personnel at the service center wherein audio signals are received and transmitted through the base unit. The video and audio signals are processed together at the base unit for synchronous transmission over a telecommunication system to the remote service center. The machinery is monitored in the plant with a cordless portable video camera by moving the portable video camera to a desired area of the operating machinery which needs monitoring. Cordless headsets, worn by plant personnel attending the machinery, are utilized to provide audio communication through the base unit at the plant.
