Levare compression pumps cover a wide range of flow rates and are very tolerant to higher thrust loads and abundant solids in the produced fluids.


Unlike floater pumps, compression pumps are better able to manage varying thrust loads in rapidly changing flow conditions as is often experienced with gas slugging. When a compression pump begins to operate in down thrust, the force is transferred and managed at the thrust bearing in the motor seal. Absorbing this down thrust force in the clean oil environment of the seal section helps extend pump run life.


Levare Packet pump is better able to withstand prolonged down thrust and abrasive production typically experienced by ESPs in unconventional well applications. The Packet pump is constructed such that as mechanical wear progresses, stage impellers will lock together in groups (configurable packets) so as to limit the axial movement of the packet along the shaft. Down thrust is then dynamically managed through a tungsten carbide (T) bearing in the diffuser at the base of each packet.

Benefits

Increased production even in challenging environments

Longer ESP run life improves ROI

Wider pump operating range helps reduce intervention costs

Levare gas handling devices allow continuous operation of ESP systems in gassy applications, increase and improve ESP production by conditioning the gas-liquid mixture and eliminating gas locks to further reduce the tendency for underload shutdowns due to gas interference in the pump.

The versatile portfolio of Levare gas handling devices provide trouble-free ESP system operation in well conditions with free gas content up to 90% at the pump intake when Levare gas separator is installed together with Vapro gas handler.

Levare gas separators provide efficient mechanical separation of free gas from the produced mixture. They are available in 272, 338, 400, and 538 series and cover virtually every production rate delivered by the extended product line of Levare pumps. Gas separators feature abrasion-resistant design and can be trusted by conventional and unconventional oil producers.

Gas separator type Max flow rate of the connected pump @ 60 Hz Max free gas at pump intake
ESP 338 RGS 1,500 bpd up to 65%
ESP B 400 VGS CW 3000 3,000 bpd up to 75%
ESP B 400 VGS CW 5800 5,800 bpd up to 75%
ESP B 538 VGS CW 9000 9,000 bpd up to 75%

The Levare Vapro gas handler efficiently handles higher percentages of free gas in gassy wells, allowing continuous operation of ESP systems in extreme gas conditions and reducing the tendency for underload shutdowns due to gas interference in the pump.



The Vapro multiphase pump incorporates an axial-flow impeller optimized to reduce gas bubble size and create a more homogenous flow regime at a higher GLR, in the pump. This mixture of gas and liquid behaves more like a single-phase fluid helping to stabilize the flow moving into the primary pump.



When the Vapro pump is run in combination with the Levare Vortex gas separator, ESP production with GVF up to 90% is achievable.

Gas separator type Max flow rate of the connected pump @ 60 Hz Max free gas at pump intake
400 Vapro 2000 717 – 2,038 bpd up to 70%

Levare was the first company in the world to commercialize the permanent magnet motor (PMM) for ESP downhole applications in 2006. Since then, Levare has deployed more than 22,000 PMMs around the world serving a variety of ESP and PCP applications.


Permanent magnets – specially engineered and embedded in the rotor – create a constant rotor magnetic field. No electrical power is consumed in generating the rotor magnetic field. As a result, the PMM rotor experiences little to no electrical losses, is more efficient, and has higher horsepower density. This translates to a synchronous PMM with a wide operating range that consumes less energy, generates less heat and is shorter in length than an induction motor of the same rating.
