P.A.S. Pump Technology
Pressure-Actuated Seal Line
P.A.S. pump technology represents an evolutionary advancement in artificial lift systems for the oil and gas industry. This technology focuses on improving the performance, efficiency, and reliability of artificial lift applications, which are essential for extracting hydrocarbons from wells.
One of the key benefits of the P.A.S. pump technology is its ability to enhance pump efficiency under varying well conditions. The pressure regulated stator design ensures optimal sealing and pumping performance, even as the well characteristics change over time. The pressure regulated stator ensures a reliable and consistent sealing performance,
allowing the pump to handle increasing pressures without compromising its functionality. This adaptability allows for efficient fluid extraction and improved production rates.
Additionally, P.A.S. pump technology offers advantages in terms of increased pressure handling capabilities. With its four times higher pressure rate per stage compared to conventional systems, it enables efficient pumping of fluids also even in extreme deep reservoirs. This improved pressure performance contributes to enhanced well productivity and better overall production results.
One further key advantage is the near elimination of chemical or temperature limitations typically associated with rubber components. This is achieved through a rubber less design that mitigates the potential negative effects of chemicals or extreme temperatures on the stator.
Rubber materials used in conventional stators can be susceptible to chemical attack or degradation when exposed to certain fluids or aggressive environments. Additionally, high temperatures can cause rubber components to deteriorate or lose their sealing properties. However, with the rubber-less design of the P.A.S. stator technology, these limitations are significantly reduced or eliminated altogether.
The thermal expansion compensation feature is another important aspect of the P.A.S. Stator technology. As temperatures fluctuate during operation, materials can expand or contract, potentially affecting the performance and sealing capabilities of the stator. The P.A.S. Pump technology incorporates mechanisms to compensate for thermal expansion, ensuring that the stator maintains its sealing efficiency across a wide range of temperatures.
Energy efficiency is a crucial aspect of P.A.S. Pump technology. By reducing friction and optimizing the sealing mechanism, this technology can achieve power savings of up to 40%* compared to systems that use rubber stators. These energy savings contribute to lower operating costs and a reduced environmental footprint.
P.A.S. Stator technology is also designed to withstand high temperatures encountered in oil and gas production. With its temperature resistance of up to 140°C due to its Daurin™ material and up to 200°C due to its Dauraspire™ material, it ensures reliable operation in demanding well environments, reducing the risk of stator failure and associated production disruptions.
Moreover, the technology incorporates automatic wear compensation, which helps maintain pump performance over time. This feature adjusts for stator wear, ensuring consistent pumping efficiency and minimizing the need for frequent interventions or replacements.
Overall, P.A.S. Stator technology represents a significant advancement in artificial lift systems for the oil and gas industry. Its improved pressure handling capabilities, rubber less operation, energy efficiency, temperature resistance, chemical resistance and automatic wear compensation make it a promising solution for enhancing well productivity, reducing costs, and improving the overall efficiency of oil and gas production.
