Filed:

Apr 18, 2012

Appl. No.:

13/814930

Inventors:

Luke William Holderman - Plano TX, US
David Smart - Dallas TX, US

Assignee:

HALLIBURTON ENERGY SERVICES, INC. - Houston TX

International Classification:

E21B 34/14

US Classification:

166319, 166373

Abstract:

A bypass assembly for use in a downhole tool comprises a chamber, a first fluid port in fluid communication with the chamber, a second fluid port in fluid communication with the chamber, a flow restrictor disposed in a first flow path between the first fluid port and the second fluid port, a piston moveable in a first direction by the application of a first fluid pressure, a biasing member, and a restraining member disposed adjacent to the piston. The biasing member biases the piston to move in a second direction opposite the first direction, and the restraining member is actuated by movement of the piston in the first direction in response to a predetermined fluid pressure. Movement of the piston in the second direction to a predetermined position configures the bypass assembly to divert fluid flow around the flow restrictor along a second flow path.

Abstract:

Sensor information is received from a set of sensors. First and second sets of machine monitoring data are generated from the sensor information. The first set of machine monitoring data is sent to a control system with a display in an operator compartment of a mobile machine. The second set of machine monitoring data is sent to a processing system that is separate from the control system.
