Applications

Deep Shale Gas Ultra‑Deep Well Fracturing

The SCF system was designed for a single, demanding job: deep shale gas ultra‑deep well fracturing. In these applications, the formation requires high treating pressures (often exceeding 10,000–15,000 psi), large fluid volumes (millions of gallons per multi‑stage completion), and sustained full‑power operation across stage after stage. The SCF system's 5,000 HP continuous rating is matched to these exact requirements. The second-generation SCF5000 pump was specifically developed to meet deep shale gas fracturing requirements for high pressure, large displacement and continuous full-load operation.

Shale Oil Development — Eastern China's First Electric Fracturing Project

In August 2022, SJ's second-generation SCF series fully electric fracturing system was deployed in Eastern China's first shale oil well factory group — the Fanye-1 test well cluster. The system achieved 24/7 continuous electric fracturing, electric fluid mixing, and electric sand conveying operations, demonstrating single-pump high displacement, high operational efficiency, low failure rates and the ability to meet continuous operation requirements.

Ultra‑High Pressure Fracturing (120MPa+)

SJ has iteratively upgraded the 5,000 HP electric fracturing skid's fluid end and optimized the SCF5000 pump's plunger structure, achieving a pressure rating upgrade to precisely match 120 MPa ultra-high pressure fracturing requirements — all while maintaining the same power output [3†L12-L13]. For the most demanding ultra-high pressure applications, SJ also offers a 175 MPa high‑pressure manifold system.

Full‑Electric Fracturing Spreads (E-Frac Fleets)

The SCF system is designed as the core of any modern electric fracturing spread. By replacing conventional diesel-driven fracturing fleets with electric SCF systems, operators achieve significant reductions: one SCF unit replaces three 2,500 HP diesel frac trucks; site area reduced by more than 67%; noise reduced by 22%; all equipment remotely operated from a single control cabin.

Offshore & Marine Fracturing Operations

The SCF5000 pump has been deployed as the core pumping component on China's first large-scale integrated fracturing vessel, "Offshore Petroleum 696″ — a critical advancement in offshore fracturing capability [3†L28]. For offshore platforms and marine fracturing spreads, the pump's electric drive, high power density, and corrosion‑resistant options make it well‑suited to demanding marine environments.

Urban Frac & Environmentally Sensitive Areas

For operators working near residential areas or in environmentally sensitive zones, the SCF's all-electric operation is transformative. Compared to diesel fleets, the SCF system reduces site footprint by 67%, cuts noise by 22%, eliminates all on‑site diesel emissions, reduces harmful pollutants such as NOx and particulate matter, and enables remote operation from a control cabin [7†L6-L8].

Frequently Asked Questions (FAQ)

Q1: What does "fully electric fracturing unit” actually mean?

A: A fully electric fracturing unit (e-frac) is a complete well stimulation system where every component — fracturing pumps, blenders, hydration units, sand delivery systems, and data control — is powered by electricity (grid, gas turbine, or field gas) rather than diesel engines. SJ's SCF series is the world's first fully electric fracturing system designed for 100% continuous full-load output, with all equipment remotely operated from a single control cabin.

Q2: What is the power rating of the SCF electric fracturing unit?

A: The SCF series delivers 5,000 HP continuous output and 8,000 HP peak intermittent power — the highest input power of any plunger pump in the world [8†L6-L7] [9†L8-L10]. In field applications, one SCF8000 unit replaces three conventional 2,500 HP diesel frac trucks.

Q3: How does this compare to conventional diesel fracturing fleets?

A: Compared to diesel fleets delivering the same total hydraulic horsepower, the SCF system reduces site equipment count and total site area by more than 67%, cuts noise by 22%, and enables all-equipment remote operation from a control cabin [7†L6-L8]. Additionally, electric drive eliminates on‑site diesel emissions, reduces harmful pollutants such as NOx and particulate matter, and can reduce fracturing costs by approximately 25%.

Q4: What is the service life of the pump head?

A: The second-generation high-strength stainless steel pump head achieves service life exceeding 2,000 hours under high-pressure continuous operation [8†L12]. In the Sinopec shale gas demonstration area, the pump head has remained in service for nearly three years without replacement — 3 to 5 times the life of conventional alloy steel pump heads.

Q5: What pressure can the SCF system achieve?

A: The SCF5000 pump can achieve up to 140 MPa (20,300 psi) depending on plunger selection. For ultra-high pressure applications, SJ has upgraded the pump's pressure capacity to precisely match 120 MPa requirements [3†L12-L13], and offers a 175 MPa high‑pressure manifold system.

Q6: How is the unit powered — grid electricity or generators?

A: Both. The SCF system can operate on grid electricity where available, or be powered by gas turbine generators running on field natural gas. The electric VFD system provides precise speed and torque control regardless of the power source.

Q7: Can I monitor pump health remotely?

A: Yes. The SCF pump can be equipped with an optional built-in temperature monitoring system that provides remote real-time detection of critical component operating temperatures — bearings, pump head, packing areas and lubrication system — enabling predictive maintenance before failures occur.

Q8: Does SJ provide the entire electric fracturing spread, or just the pump?

A: SJ supplies the complete fully electric fracturing system — pumps, blenders, hydration units, sand delivery, high-pressure manifolds, control cabins, and VFD systems — all integrated and compatible [6†L5-L7]. Standardize your entire e‑fracturing fleet on one qualified manufacturer.

Q9: Is the unit road‑legal for transport between wells?

A: Yes. Each SCF5000 electric fracturing skid weighs under 32 tons, complying with national transport regulations.

Q10: Where has the SCF system been successfully deployed?

A: The SCF system has been extensively deployed in the Fuling National Shale Gas Demonstration Area — one of the deepest shale gas fields in the world. It was deployed in Eastern China's first shale oil well factory group (Fanye-1 test well cluster) in August 2022 [6†L5-L7]. The SCF5000 pump has also been deployed as the core pumping component on China's first large-scale integrated fracturing vessel.
