Filed:

Jun 2, 2009

Appl. No.:

12/476765

Inventors:

Chen Tao - Sugar Land TX, US
Thomas Meyer - Manvel TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 36/00
F28D 7/02
F28D 7/04

US Classification:

175 17, 165156, 165163

Abstract:

Example motor cooling radiators for use in downhole environments are disclosed. A disclosed example radiator comprises a cylindrical housing having an annular passageway. The housing defines an inlet at a first end of the housing and an outlet at a second opposite end of the housing. A channel is arranged within the annular passageway of the housing along a spiral path to transport the first liquid and to define a spiral flow passageway between the inlet and the outlet for the second liquid. In operation, the first liquid does not contact the second liquid and heat is transferred between the first and second liquids as the second liquid flows in the spiral passageway.

Appl. No.:

13/935207

Inventors:

- Sugar Land TX, US
Thomas Meyer - Manvel TX, US

International Classification:

E21B 47/10

US Classification:

7315223

Abstract:

A method to determine a piston position in a sample bottle, having steps of providing a transducer near a chamber of the sample bottle, exciting the transducer to provide at least one wave of acoustic energy, propagating the acoustic energy through the chamber to a surface, reflecting the acoustic energy from the surface, receiving the acoustic energy at a receiver, determining a time of flight of the acoustic energy, and calculating the piston position from the time of flight of the acoustic energy.
