80 | August 2018 | HYDRAULIC FRACTURING: CASE STUDIES wear and did not require replacement. The onboard filtration system delivered clean oil to enhance bear- ing life through optimized control. With a traditional fracturing pump under similar conditions, the operator would have already rebuilt its fleet of pumps once, and the fleet would be on its second life. However, as the SPM QEM 3000 is fit for purpose in high-pressure operations with longer horizontals, it is poised to effectively at least double the lifespan of traditional fracturing pumps in such environments, as the equipment looks and performs like new at 3,200 hours. This saved the operator CAD 75,000 per pump, approximately CAD 900,000, not including downtime. With the QEM 3000 pumps in use, the operator is now able to run only two QEMs for every three legacy pumps in these particular basins due to the QEMs being specifically engineered to meet demand- ing requirements. While legacy pumps run a 4.5-in. plunger, the QEM can run a 5-in. plunger because of the rod load. The operator noticed that the QEM pumps run smoothly and feel safe, even at the higher rod load and horsepower. The operator is approaching using 80% of available kilowatts, helping to achieve greater efficiency. Additionally, the packing lasts up to three times longer because of improved alignment and stiffness of the frame. Having this kind of capacity and performance enables the operator to respond to market demands quickly, resulting in incremental and new revenue opportunities. The SPM QEM 3000 continues to yield unsur- passed results and savings in the field for this opera- tor, looking and performing like new after more than 3,200 hours of field-proven use in extreme conditions in the winter months in the Duvernay and Mont- ney shale plays. Given its current performance, it is expected to extend maintenance cycles by a factor of three as compared to what the operator achieved in similar service conditions previously. These enhance- ments dramatically affect their bottom line, expand- ing lifespan to improve uptime and productivity, all while reducing maintenance costs and lowering total cost of ownership by at least 17%. Operators running a QEM pump in similar conditions as the Duvernay and Montney formations could expect greater than 200% increase in pump life. n The crank assembly from the QEM 3000 shows minimal wear following 2,700 hours of service.
