Abstract:

Systems and methods for specifying one or more operational parameters for a pumping system are disclosed. A first suction pressure loss profile for a first pump in a pumping system is determined. A second suction pressure loss profile for a second pump in the pumping system is determined. The first suction pressure loss profile is compared with the second suction pressure loss profile. One or more operational parameters are specified based, at least in part, on the comparison.

US Classification:

16625001

Abstract:

A system and method for monitoring operation of a pump are disclosed herein. The methods and systems make use of acoustic sensors to collect and analyze data in order to detect cavitation. The disclosed methods and systems may also be used to detect valve damage. The pump may be a positive displacement pump that is employed in a wellbore servicing operation such as pumping a wellbore servicing fluid into a wellbore.

Appl. No.:

6/501681

Inventors:

Don M. Roberts - Duncan OK
David W. Looper - Duncan OK

Assignee:

Halliburton Company - Duncan OK

International Classification:

H05H 720

US Classification:

361384

Abstract:

An enclosure for electronic equipment includes an outer housing having an inner housing mounted therein. The inner housing has a fan and air deflector members mounted therein for maintaining a controlled circulation of air flow within the interior region of the inner housing so that air within the interior region is moved in heat exchange relationship with a heat sink member extending into the inner housing. The heat sink member in the inner housing is connected by thermal diodes with another heat sink member attached to a side wall of the outer housing. Another fan directs an air flow over the heat sink member attached to the side wall of the outer housing. A third fan is mounted within the interior region of the outer housing, but externally of the inner housing, for providing air circulation within the interior region of the outer housing.

International Classification:

E21B 2106
G01N 1104

US Classification:

73151

Abstract:

A rheology test system includes a self-propelled vehicle, a computer contained in the vehicle and a rheology flow loop skid mounted in an outboard storage compartment of the vehicle. The rheology flow loop skid includes an obliquely mounted helical conduit through which laminar flow is maintained. The helical loop is mounted on a base near an inboard side thereof, and instrumentation is mounted on an outboard side of the base so that the apparatus can be readily used while mounted on the vehicle. Improved connecting pipes provide a more compact construction and a more easily assemblable and disassemblable construction.
