US Patent:

41590368, Jun 26, 1979

Filed:

Jun 8, 1978

Appl. No.:

5/913839

Inventors:

Phillip M. Wilson - New Orleans LA
Charles L. Presley - Houston TX

Assignee:

Kobe, Inc. - Huntington Park CA

International Classification:

E21B 4300

US Classification:

166267

Abstract:

High pressure product fluid from a petroleum well goes into a high pressure separation vessel where preliminary phase separation of the constituents takes place. Oil and gas leave the preliminary separator by a flow line. Power fluid for a triplex pump flows from the high pressure separator into a separator tank that opens to atmosphere. Here, further separation of the phases takes place and power fluid low in abrasive solid content is taken off by a charging pump and fed to the triplex pump. The triplex pump increases the head of the power fluid and introduces it to the well. The power fluid may be either water or oil.

Abstract:

A separation compartment of a multiphase separation vessel receives production fluid from a petroleum well and that fluid separates by gravity into the gas, oil and water phases in the vessel. An adjustable siphon leads from a water space in the separation compartment to a discharge compartment of the vessel. The level of the discharge from the siphon determines the elevation of an oil phase-water phase interface within the separation compartment and the presence of the desired of the fluid phases at a pickup for power fluid. The siphon includes a removable line that permits a change in the elevation of the outlet of the line into the discharge compartment. Preferably, the discharge compartment comprises an upstanding pipe, the top of which acts as a weir for receiving oil from the separation compartment. Oil from the vessel may pass through a cyclone for further separation of solids from the oil and then introduced by a pump back into the well to act as the power fluid for the well. Excess oil is taken off as product in a product stream together with production gas and water.
