Filed:

Nov 19, 2003

Appl. No.:

10/717046

Inventors:

David Lush - Houston TX, US
Jonathan Eng - Sugar Land TX, US
Hikmet Ucok - Sugar Land TX, US
Dave Hopgood - Missouri City TX, US
Chris Landeck - Sugar Land TX, US
Ken Carmon - Richmond TX, US

Assignee:

Chevron U.S.A. Inc. - San Ramon CA

International Classification:

E21B 29/12

US Classification:

166357, 166267

Abstract:

A preferred embodiment of the inventive fluid delivery system comprises a vertical liquid/vapor separator and riser assembly that comprises a multi-phase separator inlet, a vapor outlet and riser, and a liquid outlet port connected to a hydraulically-driven centrifugal pump. By controlling the operational speed of the pump, the level of the separated liquid within the separator can be controlled without the need for control valves. The vertical separator is capable of low pressure operation and large variations in controlled liquid levels within the separator, allowing the relatively slow reaction time pump to control the liquid level from low pressure wells penetrating low pressure reservoirs.
