Applications

Shale gas fracturing equipment from SJ is used across the full spectrum of unconventional resource development:

1. Shale Gas Completions (Sichuan, Marcellus, Haynesville)

Multi‑stage fracturing of horizontal wells – typically 20–60 stages per well, with 200–1,000 tons of proppant per stage. Our frac pumps are rated for 24/7 continuous operation. The zipper manifold allows two wells to be fractured alternately, cutting non‑productive time by 40%.

2. Tight Oil (Permian, Bakken, Vaca Muerta)

Light oil reservoirs also require massive fracturing. Our equipment handles slickwater, crosslinked gel, and hybrid fluid systems. The blender’s high sand concentration capability (3,000+ kg/m³) is essential for tight oil.

3. Coal Seam Gas (CSG) Fracturing

Shallower, lower pressure fracturing requires smaller pumps (2,500 HP) but higher mobility. Our trailer‑mounted single‑unit spread is used in Australian CSG fields.

4. Refracturing (Re‑Frac)

Older wells can be re‑fracked. Our equipment is compact enough to operate on existing pad sites with limited space. The data van’s microseismic monitoring helps avoid fracture interference with adjacent wells.

5. Proppant Fracturing of Deep Gas Reservoirs

Some deep conventional gas wells also require fracturing. Our 15,000 psi pumps handle the high closure stresses of deep formations (10,000+ ft).

6. Offshore Hydraulic Fracturing (Jack‑Up)

Fracturing from a jack‑up rig requires compact, modular equipment. We offer offshore‑rated frac pumps with marine coatings, ABS certification, and smaller footprints.

Why Choose SJ Petroleum Machinery?

1. Sinopec‑Owned – Built by the World’s Largest Frac Operator

Sinopec is one of the world’s largest shale gas operators (Sichuan Basin, >10 Bcm/year). SJ’s frac equipment is what Sinopec uses on its own wells – not a copy, not a reverse‑engineered knockoff. That means our equipment has been refined through thousands of frac stages, in real rock, with real sand.

2. 80+ Years of High‑Pressure Pump Expertise

We’ve been building mud pumps and well service pumps since the 1950s. Our frac pump fluid ends are direct descendants of that lineage – forged, not cast; heat treated to exact hardness; and field‑proven at 15,000 psi.

3. Full API Certification & Traceability

Every frac pump, blender, and manifold component carries API monogram where applicable (7K, 6A, 16C). We supply full material certs, NDE reports, and hydrotest certificates with every unit.

4. Designed for Continuous Duty – Not Occasional Use

Shale fracturing runs 24 hours a day, 7 days a week, for weeks at a time. Our pumps feature oversized bearings, forced lubrication, and fluid end designs that resist fatigue cracking. Many of our pumps have run 10,000+ frac hours with only routine maintenance.

5. Shorter Lead Times & Competitive Pricing

Typical lead time for a 6,000 HP frac pump: 6–8 months (compared to 10–14 months for major Western brands). Blenders: 4–6 months. Complete frac spread: 8–12 months. Pricing is typically 20–30% lower for equivalent performance.

6. Modular & Mobile – Built for Pad Drilling

Our frac equipment is trailer‑mounted with highway‑legal dimensions (within 8.5′ width, 13.5′ height, 53′ length). Quick‑connect hammer unions and auto‑aligning hitches mean you can rig up a 12‑pump spread in 8 hours.

7. Global Parts & Field Service

We stock pump fluid end modules, valves, seats, packing, blender augers, and control system components in Houston, Dubai, Chengdu, and Jingzhou. Spare parts ship within 24 hours. We provide 24/7 field service engineers for major frac campaigns.

8. Technology Transfer & Training

For new operators, we offer training packages: classroom (1 week) + field (1 week) for your frac crews. We also provide remote data van support for the first 5 jobs.

Frequently Asked Questions (FAQ)

Q1: What is the typical frac spread configuration for a 10,000 ft horizontal shale well?

A standard high‑rate slickwater frac uses:

• 10–12 frac pumps (5,000–6,000 HP each) for 90–120 BPM total rate

• 1 blender (200 BPM) or 2 for very high rates

• 1 hydration unit (if using gel)

• 1 data van

• 1 zipper manifold (for multi‑well pads)

• 2–3 sand storage frac tanks (100 tons each)

• High‑pressure iron (2″ or 3″ Fig 1502)

For a single well, you may use 6–8 pumps.

Q2: What is the maximum proppant concentration your blender can handle?

Our SJ‑BL‑240 blender can handle up to 4,000 kg/m³ (about 3,200 lb/gal) – that’s heavy. Most shale fracs use 1,200–2,400 kg/m³. The limitation is usually the pump fluid end erosion, not the blender.

Q3: How long does a frac pump fluid end last?

In typical slickwater frac service (100–120 BPM, 1–2 lb/gal sand), expect 500–800 hours before valve/seat replacement is needed, and 1,500–2,000 hours before the fluid end block itself requires repair. We provide exchange fluid ends – swap out a worn block for a rebuilt one in 8 hours.

Q4: Can your equipment handle crosslinked gel, linear gel, and slickwater?

Yes. Our blenders have separate additive pumps for gel concentrate, crosslinker, breaker, and surfactant. The hydration tank can be used inline for continuous gel mixing. We’ve run all fluid types on the same spread.

Q5: Do you offer remote frac control from a single data van?

Absolutely. Our SJ‑FracControl software runs on the data van and can manage up to 32 pumps, 4 blenders, and 2 zipper manifolds simultaneously. The system includes automatic pump switching (to avoid pump cavitation) and real‑time proppant tracking.

Q6: What certifications are included for international export?

Every unit comes with API monogram (where applicable), material test reports, NDE reports, hydrostatic test certificates, and a comprehensive operations manual. For offshore use, we provide ABS or DNV classification. For EU, CE/PED.

Q7: Do you have equipment for refracturing (re‑frac) of older wells?

Yes. Re‑fracs often require smaller spreads (4–6 pumps) and precise microseismic monitoring to avoid fracture hits. Our data van includes real‑time microseismic integration. We also offer compact, single‑axle trailer pumps for tight access.

Q8: What is your warranty on frac equipment?

Standard: 18 months from shipment or 12 months from commissioning, whichever comes first. For pump fluid ends (wearing parts), we warranty against manufacturing defects only – normal wear is expected. Extended warranties up to 5 years available.
