Polyacrylamide (PAM) plays a critical role in oil and gas operations — from drilling fluid additives to enhanced oil recovery (EOR) agents. As a manufacturer supplying PAM to oilfields across 45+ countries, we see firsthand how the right polymer grade can cut drilling costs by 15-30% while improving wellbore stability.
Quick Overview: PAM in Oil Drilling
| Application | PAM Type | Molecular Weight | Typical Dosage |
|---|---|---|---|
| Drilling Fluid Viscosifier | APAM / Partially Hydrolyzed (PHPA) | 15-25 million Da | 0.5-2.0 kg/m³ |
| Shale Inhibitor | Low-MW PHPA | 6-10 million Da | 1.0-3.0 kg/m³ |
| Enhanced Oil Recovery (EOR) | Ultra-high MW APAM | 20-28 million Da | 1000-2500 ppm |
| Friction Reducer (Fracking) | Emulsion APAM | 12-18 million Da | 0.25-1.0 gpt |
| Produced Water Treatment | CPAM | 8-15 million Da | 2-10 ppm |
1. PAM as Drilling Fluid Additive
Partially hydrolyzed polyacrylamide (PHPA) is the workhorse polymer in water-based drilling muds. It increases viscosity, reduces fluid loss, and stabilizes the wellbore wall — all without the environmental concerns of oil-based muds.
Our PHPA grades for drilling typically run 15-25 million molecular weight with 25-30% hydrolysis degree. At our Zhengzhou facility, we produce these on dedicated production lines with strict viscosity control — each batch tested for dissolution time (≤90 minutes) and residual monomer (≤0.05%).
We supply our PHPA oilfield grade specifically formulated for this application — tested and proven at scale.
Key performance indicators:
- Apparent viscosity increase: 3-8x at 1.0 kg/m³ concentration
- Fluid loss reduction: 40-60% compared to untreated mud
- Shale encapsulation: prevents clay swelling and bit balling
- Temperature stability: effective up to 120°C (for standard grades)
2. Enhanced Oil Recovery (EOR)
Polymer flooding with ultra-high molecular weight PAM can recover an additional 10-20% of original oil in place (OOIP) after waterflooding. The polymer increases the viscosity of injected water, improving sweep efficiency and reducing fingering.
EOR-grade PAM demands the highest molecular weight we produce — 20-28 million Da. These grades require extremely careful manufacturing: polymerization temperature must stay within ±0.5°C tolerance, and the final product needs exceptional shear resistance to survive injection through perforations.
We supply EOR polymers to projects in the Middle East and South America, where reservoir temperatures range from 60-90°C. For high-temperature reservoirs above 85°C, we recommend our sulfonated copolymer grades that maintain viscosity where standard HPAM degrades.
3. Friction Reducer for Hydraulic Fracturing
In slickwater fracking, PAM-based friction reducers cut pipe friction by 60-80%, allowing higher pump rates at lower pressure. This translates directly to faster stage completion and lower fuel costs.
Our emulsion-type friction reducers dissolve in under 2 minutes — critical for continuous pumping operations where you cannot wait 60-90 minutes for powder dissolution. The emulsion format also eliminates dust hazards on the pad.
Typical dosage: 0.25-1.0 gallons per thousand gallons (gpt) of frac fluid. At 0.5 gpt, our FR-series achieves 70%+ drag reduction in fresh water and 55%+ in 2% KCl brine.
4. Produced Water Treatment
Oilfield produced water contains suspended solids, oil droplets, and dissolved organics. Cationic polyacrylamide (CPAM) at 8-15 million MW effectively flocculates these contaminants for removal via dissolved air flotation (DAF) or settling tanks.
Dosage depends on oil content and total suspended solids (TSS). For typical produced water with 50-200 mg/L oil and 100-500 mg/L TSS, we recommend 2-10 ppm CPAM with 30-50% charge density.

How to Select the Right Grade
Choosing the wrong PAM grade wastes money and can damage your operation. Here is our decision framework:
- Define the application — drilling fluid, EOR, fracking, or water treatment?
- Check temperature — standard HPAM works below 85°C; above that, use sulfonated grades
- Determine salinity — high TDS (>50,000 ppm) requires salt-tolerant formulations
- Match molecular weight — higher MW = more viscosity but slower dissolution
- Choose format — powder for cost efficiency, emulsion for speed

Our Quality Assurance for Oilfield Grades
Oilfield polymers demand tighter specs than general industrial grades. Our 3-tier quality control system ensures batch-to-batch consistency:
- In-process monitoring — real-time polymerization temperature curves, initiator ratio tracking
- Batch testing — every batch checked for MW (±0.5M tolerance), solid content (≥92%), dissolution time, and filterability ratio
- Pre-shipment inspection — packaging integrity, moisture protection, container loading supervision
We retain samples from every batch for 24 months. If you ever have a performance issue in the field, we can trace it back to the exact production run and compare against retained sample data.
Packaging & Shipping for Oilfield Projects
Standard packaging: 25kg PE-lined kraft bags on pallets, 20 MT per 20ft container. For large EOR projects consuming 500+ tons/month, we offer 750kg jumbo bags to reduce handling time on site.
From our Zhengzhou factory to Qingdao port takes less than 1 day. Standard delivery: 7-10 days from order confirmation. For urgent needs, we maintain buffer stock of popular oilfield grades — 3-5 day express shipping available.
We currently supply oilfield PAM to projects in Oman, UAE, Brazil, Colombia, Kazakhstan, and Indonesia. Our export team handles all documentation including MSDS, COA, and customs paperwork.
Pricing Factors
Oilfield-grade PAM typically costs 10-20% more than standard industrial grades due to tighter specifications and additional testing. Current polyacrylamide pricing for oilfield grades:
- PHPA drilling grade: $1,800-2,200/ton FOB China
- EOR ultra-high MW: $2,200-2,800/ton
- Emulsion friction reducer: $2,500-3,200/ton
- CPAM for produced water: $1,900-2,400/ton
Volume discounts apply for contracts above 100 tons/month. First-order MOQ is 500kg — enough for field trials before committing to bulk supply.
