SSP Technology

LOTSA has a technology license for using and selling a device named SuperSonic Pump (SSP), which is an Innovative Artificial Lift technology that can be deployed in wells oil production with Gas Lift infrastructure.

Innovative Artificial Lifting System, which allows to increase the oil production rate of a well previously producing by gas-lift, with the best use of the conditions of the well / reservoir, also allowing the optimization of natural gas at high pressure used as a driving fluid.

Supersonic Pump

The SSP is a supersonic jet-type lifting system developed using the Venturi tube principle. Its efficiency is based on harnessing the kinetic energy of the lifting fluid (supersonic flow) to generate sustained suction (vacuum effect).

The SSP combines the principles of a gas lift system and a conventional vacuum pump: It decreases the density of the fluid column inside the wellbore and accelerates the driving fluid to supersonic velocities, which generates suction at the bottom of the well, decreasing the flowing bottomhole pressure (Pwf), which induces an increase in the flow of formation fluids to the production tubing, resulting in an increase in well production.

SSP is installed on the tubing production at the level of Mandrel, Tubing Punch or Sliding Sleeve using a Slickline unit.

SSP Functioning Principles.

The gas, injected at high pressure through the annular pipe of the well, at the level of the pump core (convergent-divergent zone), promotes a mixture of fluids (gas / reservoir fluid) with high efficiency and energy transfer, using the increase in speed at the supersonic level.

At the pump the reconversion of kinetic energy from the injected driving fluid to potential energy occurs, generating a sustained suction (vacuum effect), which produces a decrease in the flowing bottom pressure (Pwf), inducing an increase in the oil production rate of the well, according to its productivity index (PI)
