Sovonex™ specialty pumps excel at overcoming severe pumping conditions that standard API pumps are not able to handle. Whenever pumping is impaired by high viscosity fluids, gas interference, sand production, or borehole deviation, our specialty pumps make sure pumping efficiency is restored.
Based on the proven design of Sovonex™ API subsurface pumps, most parts of our specialty pumps comply to API Spec 11AX, thus reducing maintenance costs. Still, they are often called non-API rod pumps to distinguish them from common API subsurface pumps.
These savings, however, are secondary compared to the amount of money Sovonex™ special sucker rod pumps save our customers during pumping operations.
Severe pumping conditions lead to less fluid pumped, which directly translates into a financial loss. In addition, some pumping problems like gas locking and sand production require costly workover services and increase non-productive time.
Our special rod pumps are categorized according to their field of application, such as sand control and gas control pumps, and are best used in combination with our API sucker rods.
Sand laden fluids exert strong abrasive forces on the barrel, plunger, and valves, resulting in high maintenance costs and and impaired production.
In response to this problem, we have developed a series of non-API sand pumps, such as longer plunger pump, that show excellent performance in sandy wells.
The special design of these pumps ensures that sand particles and other solids cannot interfere with the pump components anymore, which means lower maintenance costs and enhanced pumping efficiency.
In order to allow us to select the most suitable high sand pump for your application, all you need to do is inform us about your special downhole conditions.
When heavy crude is produced with a standard sucker rod pump, a severe loss of production can often be observed.
The viscous fluid’s resistance to flow delays closing of the valves, resulting in incomplete pump fillage and reduced pumping performance. Service life is of the pump is shortened due to increased friction and pressure built-up.
Sovonex™ non-API high viscosity pumps address these problems by either providing a larger flow area or directly reducing the viscosity of the production fluid.
Our electric heating pump is an example of the latter category. This pump raises the temperature of the crude efficiently by means of an electric cable run through a hollow sucker rod string into the pump’s heating chamber.
In order to allow us to select the most suitable high viscosity pump for your application, all you need to do is inform us about your special downhole conditions.
In wells with a high gas-to-liquid ratio (GLR) gas interference severely impairs pumping efficiency.
When during the upstroke gas escapes from the production fluid, fillage of the pump chamber is incomplete resulting in a gas pound or even a gas lock.
A gas pound significantly reduces pumping performance and puts enormous stress on the entire pumping system during the downstroke, a gas lock brings completely brings pumping to a halt.
The Sovonex™ non-API gas pump overcomes these problems easily. Instead of a traveling valve, it is equipped with a strong on-off valve mounted on a pull bar. This design provides a way for the gas to enter the tubing string without impeding pumping efficiency.
At great seating depths, the borehole pressure and weight of the fluid column acting on the pump can exceed the calculated seating depth of a standard API subsurface pump. Especially the seating assembly is prone to failure.
Sovonex™ deep seating pumps are designed to make pumping operations in deep wells save and predictable. Several features contribute to the good performance of these special rod pumps:
In order to allow us to select the most suitable deep seating pump for your application, you only need to inform us about your special downhole conditions.
Sovonex™ specialty rod pumps extend to other fields of application as well and include special purpose pumps for separate zone production, deployment in deviated wells, as well as custom-made pumps.
If none of our non-API sucker rod pumps or specialty pumps meet your special requirements, we might still be able to help you. You only need to inform us about your well conditions and we will suggest a suitable pump for you.
