Case Study
Stage 1 · Customer Problem
📋 Customer Background & Pain Points
A Middle Eastern oilfield operation company is responsible for the development and operation of a large-scale oilfield in that country. The oilfield is one of the country's key oil production zones, with its operational site distributed across numerous drilling platforms, mobile power stations, and heavy-duty operational vehicles. In the daily operations of the oilfield, fuel quality is a critical factor affecting production efficiency and equipment reliability.
🏜️
Drilling Dust Environment
Frequent sandstorms deposit large quantities of fine dust particles (silicates) into storage tanks, with fuel cleanliness far below engine requirements and contamination recurring continuously.
⚡
24/7 Uninterrupted Power Demand
Drill rig generator sets must run continuously around the clock. Any fuel-related stoppage directly halts drilling operations and causes significant production losses.
🔧
Sensitive HPCR Systems
Generator sets use High-Pressure Common Rail (HPCR) fuel systems. Micron-level impurities cause injector nozzle seizure, leading to costly precision-component replacement.
🚚
Remote Supply Chain
The oilfield is located in a remote desert area. Engine filter cartridges are consumed quickly, and frequent spare parts supply and manual maintenance generate high logistics and labor costs.
🔬 Before / After Fuel Analysis
Laboratory sampling of diesel drawn from the oilfield's storage and dispatch points was conducted before and after deployment of the Jingyuan filtration system. The results below compare the baseline contamination with the post-treatment fuel quality delivered to the generator sets.
| Parameter | Before (Baseline) | After (Treated) | Improvement |
|---|
| ISO 4406 Cleanliness | ~22/20/17 | 14/12/9 | 8 levels ↓ |
| Free Water Content | ~180 ppm | ≤50 ppm | ≥72% ↓ |
| Visual Appearance | Slightly cloudy | Clear & transparent | Restored |
| TAN (mgKOH/g) | 0.15 | 0.08 | 47% ↓ |
| Particle Composition | Drilling dust, pipeline rust, sand grains | Negligible | Removed |
Note: Baseline samples reflected heavy silicate ingress from desert sandstorms combined with corrosion products from aging transfer pipelines. Post-treatment fuel met the cleanliness requirements of modern HPCR fuel systems.
🛠️ Jingyuan High-Flow Filtration System
Jingyuan customized 4 sets of 20m³/h high-flow filtration equipment for this enterprise, deployed at the oilfield's internal fueling station and core operational zones. Using Jingyuan® polymer rigid composite membrane, the system leverages the oleophilic-hydrophobic properties of the membrane material to efficiently intercept particulate impurities while synergistically removing trace free water, ensuring dispatched fuel is clear, transparent, and meets cleanliness standards. For high-temperature environments above 50°C, the electrical control system has been thermally optimized and equipped with sun shielding.

📈 Measured Outcomes
After the system was put into operation, the diesel quality used within the oilfield improved to ISO 14/12/10 level. Through the 20m³/h high-flow design, "filter-while-filling" was achieved during fuel intake and dispatch stages, effectively improving operational efficiency. The fuel system failure rate of related drilling equipment decreased significantly.
| Metric | Before | After | Change |
|---|
| Fuel Cleanliness (ISO 4406) | 22/20/17 | 14/12/9 | 8 levels improved |
| Injector Nozzle Failures / yr | ~14 | ~2 | −86% |
| Annual Filter Consumable Cost | High (frequent replacement) | ¥0 (regenerable membrane) | Eliminated |
| Generator Set Downtime | Frequent unplanned stops | Near-continuous operation | −85% |
| Free Water in Fuel | ~180 ppm | ≤50 ppm | ≥72% reduced |
Note: The regenerable polymer membrane eliminated recurring cartridge procurement, removing the logistics burden of shipping filter spares to the remote desert site.
💡 Key Takeaways & Replication
✅
Key Success Factor
The 20m³/h high-flow design matched the oilfield's large-scale rapid oil transfer demand, enabling "filter-while-filling" without slowing dispatch. The regenerable polymer membrane delivered 24/7 reliability under continuous desert operation, eliminating consumable dependency in a remote supply chain.
⚠️
Common Pitfall
Many oilfield operators rely on traditional disposable filter cartridges, which clog rapidly under high silicate dust loads and drive constant replacement logistics. Ignoring the combined effect of dust ingress, temperature swings, and free water on HPCR fuel systems leads to recurring injector failures and unplanned generator stoppages.
🔄
Replication Advice
This solution is directly applicable to other oilfield power generation and drilling scenarios — including mobile power stations, heavy-duty operational vehicles, and remote wellhead generators. Specify flow rate to match transfer demand, select explosion-proof enclosures for hazardous zones, and add thermal shielding where ambient temperatures exceed 50°C.
