Applications – Where Our Fracturing Technology Excels

Our fracturing technology is deployed across the full spectrum of well stimulation, but it is particularly suited for:

• Ultra‑deep shale gas (3,500m – 5,000m) – The SCF8000’s 175 MPa rating is designed for formations like Sichuan’s Longmaxi, where treating pressures routinely exceed 120 MPa. Our electric spreads have set single‑well stage records in this basin.

• HPHT conventional gas wells – When deep gas requires fracturing at 140+ MPa, standard 105 MPa equipment is inadequate. Our technology provides a safe operating margin.

• Large‑scale multi‑well pads – The SCF8000’s 3:1 horsepower‑to‑footprint ratio allows you to pack 40,000+ HP into a pad that would otherwise require 12–15 diesel units.

• Low‑emission / noise‑sensitive projects – Electric fracturing with zero on‑site emissions and 22% lower noise is increasingly required for urban‑adjacent wells and operators with carbon reduction targets.

• Continuous‑duty fracturing campaigns – When the program runs 24/7 for weeks at a time, our continuous‑rated pumps and predictive maintenance technology keep you pumping without unplanned stops.

Why Choose SJ Petro for Fracturing Technology?

Because technology is only valuable when it works in the field – not just in a lab.

Your Technological Need	SJ Petro’s Answer
"We need to reduce emissions and noise on our pads.”	SCF8000 electric: zero on‑site emissions, 22% lower noise. Proven in China’s deepest shale.
"Our deep wells require 140 MPa. Standard iron won’t hold.”	175 MPa rated pumps and manifolds – continuous, not peak. Field‑proven at 140 MPa.
"We’re tired of fluid end failures every 500 hours.”	10‑inch stroke, 7‑cylinder, stainless steel fluid end – 2,000+ hours in high‑sand shale.
"We want to automate our spread – one operator, not ten.”	SOFElink digital platform: one screen controls pumps, blenders, and wellhead valves.
"We need predictive maintenance, not reactive repairs.”	SOFElink monitors valve impact, packing, bearings, and alerts before failure.
"We have existing pumps from another brand. Can we still get digital control?”	SOFElink retrofit kit works with most major pump brands.

Frequently Asked Questions (FAQ) – Fracturing Technology

Q1: What is the single biggest technological advance in fracturing in the last decade?

A: Electrification combined with digital control. Diesel engines are fundamentally limited – they’re inefficient, noisy, and emission‑intensive. The move to electric drive (like our SCF8000 platform) opens up continuous high‑power operation, zero on‑site emissions, and the ability to precisely control pumps via software. When you add digital intelligence (SOFElink), you get predictive maintenance, millisecond‑level optimization, and one‑operator control. That combination – electric power + digital brain – is the biggest leap since the shift from triplex to quintuplex pumps.

Q2: How does your 8,000 HP electric technology compare to diesel in total cost of ownership?

A: For a large shale fleet running 5,000+ hours per year, the total cost of ownership (TCO) of electric is 15–25% lower than diesel over five years, despite higher upfront cost. The savings come from fuel (electricity vs. diesel), maintenance (no engine rebuilds), and reduced downtime (predictive maintenance). We provide a free TCO calculator with every quote – you input your local electricity and diesel prices, and we show the break‑even point.

Q3: What is the maximum treating pressure your technology has achieved in the field?

A: 140 MPa (20,300 PSI) continuous in Sichuan Basin deep shale wells. The equipment is rated to 175 MPa, so there is still margin above current field requirements. We have also successfully tested to 175 MPa on our factory test stand.

Q4: Can your digital fracturing technology (SOFElink) be retrofitted to other brands of pumps?

A: Yes. Our SOFElink retrofit kit includes vibration sensors, temperature probes, pressure transducers, and a data gateway. It works with most major pump brands (Halliburton, NOV, Schlumberger, Weir, etc.) and can integrate with existing control systems. The retrofit typically takes 2–3 days per pump and does not require major modifications.

Q5: How does your 10‑inch stroke, 7‑cylinder pump design extend fluid end life?

A: Fluid end life is determined by fatigue cycles. A 10‑inch stroke means the plunger moves 10 inches per cycle. For the same flow rate, a longer stroke pump completes fewer cycles per barrel than a shorter stroke pump. Fewer cycles = less fatigue. Additionally, seven cylinders share the load more evenly than five or three, reducing peak stress on any single cylinder. In field data, our 10″ stroke, 7‑cylinder design achieves 2,000+ hours between major rebuilds – roughly double the life of conventional 8″ stroke quintuplex pumps.

Q6: What power source is required for your electric fracturing technology?

A: The SCF8000 requires a 6–10 kV, 50/60 Hz AC power source with sufficient capacity (approximately 6 MW per unit at full load). Options include:

• Direct grid connection – lowest operating cost

• Mobile substation – stepped down from medium‑voltage transmission lines

• Generator bank – diesel or gas turbine generators (higher operating cost, but still lower than diesel pumps)

If grid power is unavailable, we can supply a complete mobile substation as part of the fracturing spread.

Q7: What training do you provide for operators new to electric fracturing technology?

A: For every SCF8000 purchase, we include:

• 2 weeks of on‑site training during commissioning (up to 6 operators)

• SOFElink simulator for offline practice

• Digital operation and maintenance manuals

• 6 months of remote video support

• Access to our online training portal (videos, checklists, troubleshooting)

Electric fracturing is actually simpler to operate than diesel – fewer moving parts, no engine surprises. Most crews are comfortable within 3–5 days.

Q8: Does your fracturing technology support remote operation (e.g., from a central office)?

A: Yes. SOFElink Cloud allows authorized personnel to monitor and, with proper safety interlocks, control fracturing operations from any internet‑connected location. This is used by some operators for expert support during complex jobs. For safety reasons, the primary control remains on‑site, but remote monitoring is fully supported.
