Paper: Closed Power Hydraulic Pumping Systems

Closed Power Hydraulic Pumping Systems, introduced in 1950, have been applied almost exclusively to the town-lot and off-shore island-platform operations. The ability of the "closed system" to minimize the size of power fluid treating systems is particularly advantageous where space limitations exist. This presentation will attempt to focus on the other features of the closed power fluid application, particularly those applicable to today's pumping requirements. Of particular interest are production requirements involving: 1- High water cuts from natural or artificial floods; 2- Hard to clean crudes; 3- Dual or multiple zone pumping; 4-Use of fluids other than produced crude as power fluid.
