SlimLine ESP systems use a permanent magnet motor and high-efficiency pump stages to produce wells with casing sizes as small as 4 and 4.5 in. (102 and 114 mm). Available in 2.72-in. (69-mm) and 3.19-in. (81-mm) sizes, our SlimLine systems are ideal for use in wells with high dogleg severity and when accessing sidetrack laterals. Built on proven PowerSave ESP system technology, these slim ESPs reduce power consumption by 25–30% compared to the most efficient ESPs driven by induction motors.
Even so-called slimline ESPs most commonly available on the market (400 and 338 series) are still too large to navigate easily through many wells. So the operator either settles for leaving the ESP too high in the wellbore (resulting in greater lifting costs, lower production rates, and reduced overall recovery), or tries a series of risky maneuvers to push the ESP deeper, nearer the perforations and production zone. If the ESP becomes stuck in the wellbore, fishing is typically not an option because there is not enough space between the outside diameter (OD) of the ESP and the inside diameter (ID) of the casing to latch on to it. In some cases, there is no option but to abandon the well.
Novomet offers SlimLine ESPs in 272 and 319 series configurations. Including the cable, these ESP systems have a final OD of 3.23 in. (82 mm) and 3.74 in. (95 mm) respectively, making them ideal for use in 4-in. and 4.5-in. casing.
Our slimline ESPs are powered by a 3.19-in. permanent magnet motor, saving on power and reducing overall lifting costs.
These systems are among the slimmest on the market, helping them glide through the doglegs common in hastily drilled wellbores. Their narrow profiles also enable them to pass through sidetracks to revive production in nonproducing wells. They can also be run in larger casing sizes for multizone production and for injecting and producing through the same wellbore.

The SlimLine ESP uses pump-stage designs that deliver up to a 20% increase in efficiency, and permanent magnet motors shown to increase efficiency 15% compared to asynchronous induction motors. The result is a tough, reliable ESP that reduces power consumption by at least 25%. With installs nearing 1,000 around the world, our SlimLine systems have an average runlife of 490 days.
Auxiliary options available in 3.19-in. sizes are multiphase pumps, advanced gas handlers, scale preventers, gas separators, and slotted screen filters.
