The SQP1000 Quintuplex Plunger Pump is deployed across a broad spectrum of demanding oilfield operations:
Fracturing Operations – High-pressure, high-volume injection of fracturing fluids for reservoir stimulation. The SQP1000's continuous-duty rating and smooth flow make it ideal for extended fracturing jobs.
Cementing Operations – High-volume pumping of cement slurry for well completion, including self-dispensing of cement slurry, slurry pumping, displacing slurry, and pressure testing
Acidizing Operations – Pumping acid solutions for well stimulation and formation treatment
Well Killing – High-pressure fluid injection for well control
Coiled Tubing Operations – Continuous pumping for extended coiled tubing services. The quintuplex design's reduced pulsation and smooth flow are particularly advantageous for coiled tubing applications.
