Applications

SJ Petro’s Series Cementing Plunger Pumps are deployed across a broad spectrum of oilfield operations:

• Cementing Operations – Pumping cement slurry for well completion, including self-dispensing of cement slurry, slurry pumping, displacing slurry, and pressure testing. TPH400 pumps are the traditional workhorse for cementing operations.

• Acidizing Operations – Pumping acid solutions for well stimulation. TPD/TPE 600 triplex pumps are specifically designed for cementing and acidizing applications.

• Fracturing Operations – High-pressure injection of fracturing fluids for reservoir stimulation. The QPE 1600 quintuplex pump is ideal for fracturing operations with its 1,600 bhp capacity.

• Sand Control – Gravel packing and sand control operations.

• Coiled Tubing Operations – Continuous pumping for coiled tubing services. The QPE 1600 is particularly suited for extended coiled tubing operations.

• Well Killing – High-pressure fluid injection for well control.

• Circulating Operations – Fluid circulation in drilling and workover operations.

• Intermittent Well Service – Acid treatment, cementing, fracturing, and other intermittent operations.
