The Impala extended-range ESP system delivers steady performance – even through unstable, low, or rapidly declining flow. No more shutdowns for equipment replacements – one Impala ESP handles conditions that used to require multiple ESP systems.
Conventional and unconventional wells rarely produce at a steady rate. As production declines or fluctuates, the operating point of a conventional Electrical Submersible Pump (ESP) can move outside its recommended flow range, causing unstable operation, unplanned ESP workovers, higher operating costs, and lost production.
The Impala extended-range ESP system is engineered for variable-flow, low-rate, and declining-production wells. Its wide operating flow range helps maintain production without changing the ESP configuration as well conditions evolve.
Efficient axial load management extends ESP run life across a broad operating range and supports reliable performance in abrasive, solids-laden fluids.
The Impala ESP handles wide-ranging and shifting production rates – no need to change out equipment every time well conditions change.
Low-axial-force stages manage thrust across the operating range, extending equipment run life.
Abrasion-resistant ESPs hold up in fluids laden with mechanical solids and abrasive particles.
Semi-compression (SCMP) assembly design removes the need for shimming, making ESP installation considerably easier.
Impala ESP comes in three equipment lines, each suited to a different solids content environment.
*On request, Impala Premium ESP line can be designed with a 1:1 bearing configuration — a radial-thrust bearing in every stage — for the highest run life in heavy abrasive conditions.
Each bar shows the 60 Hz flow range for each ESP model. Together, they cover production from a few hundred to nearly seven thousand barrels per day — helping you select the right ESP string for the required operating conditions.
Per-stage flow rate at 60 Hz / 3490 rpm on water of 1.00 sg. The operating range can be further widened through frequency control.
Conventional, unconventional wells with fluctuating or rapidly declining production rates — tight reservoirs and deeper production zones.
Wells complicated by mechanical solids and abrasive particles, where conventional ESP stages wear out early.
Wells where the PI is not yet known or varies across a wide range.
Wells with a low productivity index and high required head.
Filter by pump series, then click any column header to sort. All performance values are per single stage at 60 Hz / 3490 rpm on water of 1.00 sg.
