High-Efficiency ESP Pumps

Schlumberger Artificial Lift offers the widest capacity range of submersible pumps in the industry. These pumps can handle production rates from 100 to 95,000 bbl/d and can produce from depths of 15,000 feet.

In addition to typical applications in oil, water, and brine production, pumps are used for booster service, ballast transfer, waterfloods, direct injection, cavern storage, mine dewatering, fire protection, irrigation, and commercial water systems.

Submersible pumps are multistage centrifugal pumps. Each stage consists of a rotating impeller and a stationary diffuser. Stage materials are Ni-Resist, Ryton, or special metallurgies for optimum performance in corrosive or abrasive wells.

MONEL alloy K-500 shafts are standard on all pumps. Optional high-strength shaft material is also available.

Corrosion-resistant coatings and ferritic steel construction are available for protection in H₂S, CO₂, and similar corrosive environments.

For abrasive applications where maximum pump life is required, the patented ARZ pumps with zirconia ceramic bearings and compression-ring construction are the most technologically advanced submersible pumps available. The compliant-mounted zirconia bearings have repeatedly shown 100 times less wear than hardened alloy bearings in tests and actual field performance.
