Explore our engineering-grade cyclonic separation equipment, dewatering modules, and sand removal units engineered for severe offshore and onshore operating environments.
Addressing the paradigm shift in conventional and unconventional hydrocarbon extraction water management.
As mature oilfields across North America, the North Sea, the Middle East, and Southeast Asia age, water-to-oil ratios (WOR) continue to rise exponentially. Operating companies routinely process between 3 to 10 barrels of produced water for every single barrel of crude oil extracted. Managing these extreme fluid volumes under tightening regulatory regimes demands high-throughput, low-footprint OEM technology capable of continuous operations without mechanical failure.
Environmental regulatory authorities worldwide have drastically lowered permissible Oil-in-Water (OIW) discharge thresholds. Offshore discharge standards under OSPAR guidelines require concentrations consistently below 30 mg/L (ppm), with localized jurisdiction limits pushing toward 15 ppm or less. For onshore deep-well reinjection, particulate content and suspended solids must be removed down to sub-micron scales to prevent formation plugging and catastrophic reservoir damage.
Offshore topside structures and floating production storage and offloading units (FPSOs) operate under strict spatial and structural weight limits. Traditional gravity settling tanks and conventional skim vessels are no longer viable due to their massive size and heavy operational wet-weights. Advanced cyclonic produced water disposal packages provide up to 80% reduction in equipment footprint while delivering superior liquid-liquid and solid-liquid phase separation efficiency.
Key Takeaway for Procurement Directors: Modern oilfield development demands modular, high-capacity produced water disposal systems that combine mechanical simplicity with aggressive phase-separation metrics. Partnering directly with a specialized OEM supplier ensures cost efficiency, custom skid integration, and immediate compliance with international offshore and onshore standards.
Mastering four-phase (Oil, Gas, Water, Sand) separation dynamics through advanced hydrocyclonic engineering.
Produced water is a complex emulsion containing dissolved hydrocarbon gas, free and emulsified oil droplets, dissolved mineral salts, chemical additives, and solid particulates (formation sand, scales, and corrosion products). Efficient disposal or re-injection requires a multi-stage separation architecture engineered to handle fluctuating inflow rates and dynamic shear forces.
Deoiling hydrocyclones utilize extreme centrifugal acceleration—frequently exceeding 1,000 Gs—to separate light-phase dispersed oil droplets from the heavy-phase water stream. The hydrocyclone geometry accelerates fluid tangentially, driving heavier water outward against the liner wall while forcing oil droplets to coalesce into a central low-pressure core, which is ejected through an overflow reject orifice.
Solid particulates such as quartz sand and iron sulfide cause abrasive wear on valves and pumps, while plugging reinjection wells. Solid desanding hydrocyclones strip dense abrasive solids from produced water prior to delicate downstream treatment units. Integrated accumulation pots allow for continuous or batch purging and sand washing without interrupting system flow.
The PR-10 series represents a breakthrough in high-g cyclonic polishing. Designed specifically to catch sub-micron suspended solids and ultra-fine particulate matter that evade conventional cyclones, the PR-10 minimizes chemical flocculant consumption and preserves injection formation permeability in ultra-deep disposal wells.
Innovating the next generation of smart, automated, and zero-emission fluid separation systems.
Future produced water treatment facilities are shifting from static operational parameters to dynamic digital twin systems. By integrating real-time laser droplet sizing sensors, dynamic differential pressure controllers, and AI predictive maintenance algorithms, modern separation skids automatically adjust reject ratios based on incoming oil concentration spikes, preventing oily water carryover during slug flow events.
To eliminate the cost of pumping massive volumes of produced water to surface platforms, subsea separation systems are being deployed directly on the seabed. Seabed hydrocyclones and desanding packages separate water at seabed pressure, re-injecting it into reservoirs immediately. This drastically reduces topside power demands and cuts greenhouse gas emissions associated with fluid elevation.
For onshore shale oil and tight gas plays facing strict aquifer protection laws, produced water disposal is shifting toward reuse and Zero Liquid Discharge (ZLD). Mechanical vapor recompression (MVR) combined with high-efficiency cyclonic pretreatment enables operators to recycle 95%+ of flowback water for hydraulic fracturing, eliminating regional disposal well reliance.
Shanghai Shangjiang Petroleum Engineering Equipment Co., Ltd. (SJPEE.CO., LTD.)
Shanghai Shangjiang Petroleum Engineering Equipment Co., Ltd. (SJPEE.CO., LTD.) was established in Shanghai in 2008. The factory covers an area of 4,820 m² with a total factory building area of 5,700 m². Strategically located at the mouth of the Yangtze River, our facility enjoys exceptionally convenient water and land logistics for worldwide heavy equipment dispatch.
The company has always been committed to developing advanced separation equipment and filtration systems tailored to the demanding requirements of the oil and gas industry. Technically, we continuously optimize and elevate cyclone separation technologies. Guided by our core operational principles—"Strict management, quality first, quality service, and customer satisfaction"—we deliver reliable, low-cost, high-efficiency separation skids, finished equipment, third-party system retrofits, and comprehensive field after-sales support.
Implementing total quality management in strict compliance with ISO-9001 standards, SJPEE maintains a complete service structure supporting global clients across pre-sales analysis, custom manufacturing, and field commissioning. Our engineering products are exported to Singapore, Thailand, Malaysia, Indonesia, Russia, and beyond, earning widespread acclaim from international operators.
Flexible commercial models for EPC contractors, field operators, and equipment leasing firms.
For major capital expenditure projects, SJPEE offers volume-tier pricing on custom-built produced water disposal skids, hydrocyclone liners, and vessel internals. Every skid is engineered according to exact field temperature, pressure rating, fluid viscosity, and salinity parameters, featuring full material traceability and ASME/CE compliance.
To reduce upfront CAPEX during well testing or temporary production surges, we provide flexible equipment leasing arrangements. Our lease fleet includes mobile containerized desanding hydrocyclones, PR-10 fine particle removers, and pilot testing units configured for immediate field hookup and rapid mobilization worldwide.
Operators with existing, underperforming separator vessels can leverage SJPEE retrofits. By replacing inefficient internal baffles or obsolete hydrocyclones with our modern high-efficiency cyclonic insert bundles, facilities can double their treatment capacity without replacing costly pressure vessels.
Ensuring frictionless field deployment across regional regulatory frameworks.
All test equipment and commercial produced water disposal packages undergo rigorous factory acceptance testing (FAT). Certified under CE directives and ISO-9001 frameworks, our systems meet stringent European Union and international safety and environmental regulations, ensuring smooth site acceptance and operator sign-off.
From initial field survey through to mechanical completion and final commissioning, SJPEE engineers provide hands-on technical guidance.

Expert insights into produced water disposal technology, operational parameters, and equipment selection.
A: Standard deoiling hydrocyclones focus on liquid-liquid phase separation (removing droplets down to 10-15 microns). The PR-10 is specifically engineered for ultra-fine solid particle separation and micro-droplet polishing, capturing sub-micron particulate contaminants that cause formation plugging in deep injection wells.
A: Hydrocyclones utilize strong centrifugal acceleration (up to 1,000+ Gs) to accelerate phase separation by orders of magnitude compared to 1-G gravity settling. This reduces fluid residence time from hours to seconds, cutting equipment footprint and operational wet-weight by up to 80%.
A: Yes. All electrical components, instrumentation, control panels, and automated valves integrated into our produced water disposal skids can be engineered and certified to Zone 1 or Zone 2 hazardous location standards (ATEX, IECEx, or NEC directives).
