SCF5000 Continuous Full-Load Fracturing Pump for Mature Oilfield Refracturing: Give Tired Wells a Second Life

Technical Specifications

Key Applications

Mature Oilfield Refracturing & Re‑Entry

The SCF5000 is your heavy artillery for refracturing mature assets. Whether you are re‑stimulating old conventional wells or going for a re-frac in unconventional plays, the sustained high pressure and volume of the SCF5000 is essential to break down old perforations and extend fracture networks into new, untouched payzones.

Ultra‑Deep Shale Gas & Tight Oil Refracturing

Formations buried deeper than 3,500 meters create unique refracturing challenges. The extreme closure stresses require breakdown pressures exceeding 100 MPa. Our SCF5000 units have successfully executed over 1,600 ultra‑high pressure stages across various deep basins, using its continuous power to pump massive slickwater volumes at rates above 22 m³/min.

Extended "Factory Mode” Refracturing Campaigns

When you're executing a multi-well pad refracturing campaign, downtime kills your economics. The SCF5000’s 24/7 continuous duty cycle allows you to pump for 9+ hour stages, day after day, without the mid-job equipment swaps or cooldown periods required by intermittent‑duty pumps.

175 MPa Ultra‑High Pressure Fracturing

For the deepest, tightest refracturing jobs, we offer a field‑optimized version of the SCF5000 capable of hitting and sustaining pressures up to 175 MPa. This system has already set basin records for treating pressures in ultradeep refracs, allowing you to access reserves that were previously considered uneconomical.

Multi‑Well Zipper Fracturing

Modern zipper fracturing operations demand a pumping fleet that can instantly switch between wells without losing pressure or flow. The SCF5000’s responsive electric drive and continuous‑duty fluid end handle the instant load changes of zipper fracs with ease.

Why Choose SJ Petroleum Machinery?

One of the World’s Largest Fracturing Pump Manufacturers

SJ Petroleum Machinery is a 100% wholly‑owned subsidiary of Sinopec Oilfield Equipment Corporation (SOFE). With decades of heritage building drilling, cementing, and fracturing equipment for the most demanding geological basins on the planet, we don't just know pumps—we understand reservoir dynamics. Our 6,000 HP pump test center is one of the largest in the world, and our annual fracturing equipment output exceeds 200 units.

Dual‑Testing for Absolute Peace of Mind

Every SCF5000 is subject to our rigorous "Million‑Cycle” qualification test and a full 2‑hour dyno test before it leaves the factory, monitored in real time for temperature, vibration, and performance. You get complete test reports, material certifications, and a serialized log for every unit.

Ultra‑High Pressure Specialists

While many competitors plateau at 100 MPa or 125 MPa, we have already deployed SCF5000 units in active 175 MPa service. Our team understands the specific metallurgy and failure modes of ultra‑high pressure fracturing, and we have the R&D data to back it up.

Built For Global Operations

As a premier exporter of high‑pressure equipment, we understand international logistics. Our pumps are crated for sea freight, certified for global road transport, and serviced via our regional parts hubs in Houston, Dubai, and Shanghai. Third‑party inspections (SGS, BV) are always welcome.

The Lowest Total Cost of Ownership in Its Class

With 2,000+ hour fluid end life and 8,000+ hour power end life, the SCF5000 dramatically reduces your cost per pumped stage. Fewer maintenance events, fewer pumps on location, and higher operational uptime mean you frac more rock for less money.

Frequently Asked Questions (FAQ)

Q1: What exactly is "continuous full load,” and why does it matter for refracturing?

"Continuous full load” means the SCF5000 can operate at its maximum rated power of 5,000 HP for 24 hours a day, 7 days a week, without thermal derating or mandatory cooldown. For refracturing, where long pump times (9+ hours) and high pressures (100+ MPa) are the norm, a continuous‑duty pump will finish the job while an intermittent‑duty pump might fail halfway through. As the first electric fracturing system with 100% continuous output capability, this redefines what's possible for mature field re‑stimulation.

Q2: My current pumps are rated for 120 MPa. Can the SCF5000 really handle 140 MPa or 175 MPa?

Yes. We have optimized the SCF5000’s fluid end and plunger geometry to reliably achieve pressure class upgrades without sacrificing its massive 5,000 HP output. Our system has set field records in 140 MPa service and is actively deployed in 175 MPa operations today. The key is not just the pump itself—we can also supply the companion 175 MPa high‑pressure manifold system to complete the job safely.

Q3: What is the typical lifespan of the fluid end and power end?

In continuous, high‑pressure service:

• Fluid End (Pump Head): 2,000+ hours (second‑generation high‑strength stainless steel)

• Power End: 8,000+ hours
  These numbers are based on actual field data from multi‑stage ultradeep refracturing campaigns. Compare that to standard fluid ends that often fail at 500–800 hours in similar conditions.

Q4: Is this a diesel or electric pump?

The SCF5000 is an electric fracturing pump. Electric drive offers higher reliability, lower maintenance, quieter operation (<85 dBA), and zero direct emissions. For mature field refracturing where you may have grid access or field generation, electric is the clear winner for continuous duty.

Q5: How many pumps do I need for a typical refracturing spread?

Because the SCF5000 provides 5,000 continuous HP in a single skid, you can often reduce your total pump count by 30–40% compared to a conventional 2,500 HP diesel fleet. Fewer pumps means less rig‑up time, lower fuel/power costs, and a smaller environmental footprint.

Q6: What’s your warranty and after‑sales support?

18 months from shipment or 12 months from commissioning (whichever occurs first). We maintain a dedicated fracturing pump support team available 24/7 via phone, email, or video call. Critical spare parts are stocked in Houston, Dubai, and Shanghai for rapid air freight delivery.

Q7: Can I see third‑party validation or field references?

Absolutely. The SCF5000 has been deployed across thousands of stages in the Fuling shale gas field, Sichuan Basin, and other mature basins. We can provide customer references and, subject to confidentiality, field performance summaries.

Q8: How do I size an SCF5000 for my refracturing project?

Provide us with your target treating pressure (psi or MPa), desired flow rate (bpm or m³/min), expected stage duration, and well depth. Our fracturing applications engineers will respond with a pump configuration recommendation, a full technical datasheet, and a fixed price quote – typically within 3 business days.
