Schlumberger offers an array of multistage centrifugal ESPs for a wide range of flow rates, from 200 to 96,000 bbl/d with boost pressures of up to 6,000 psi and extended run lives. Each stage consists of a rotating impeller and a stationary diffuser, designed to deliver the best combination of hydraulic efficiency and lift performance. Special alloys and zirconia or silicon carbide ceramic bearings provide optimal performance in corrosive or abrasive wells. The compression design extends the flow rate range and improves reliability in changing or uncertain production with high GOR.
