Industrial Applications

Coarse Mesh Applications (20/40, 30/50)

Ideal for wide fractures in high-permeability formations. Low-density grades reduce settling, while high-density options provide maximum conductivity in deep, high-pressure wells up to 15,000 psi closure stress.

Fine Mesh Applications (40/60, 40/70, 70/140)

Optimised for narrow fractures and complex fracture networks. Excellent for unconventional reservoirs requiring precise proppant placement and sustained conductivity under moderate to high closure stresses.

Deep Well Operations

High-density, high-crush-resistance grades (103 MPa) enable successful fracturing in wells exceeding 10,000 feet depth where extreme closure stresses would crush conventional proppants.

Unconventional Reservoirs

Comprehensive product range addresses diverse requirements in shale gas, tight oil, and coalbed methane formations with tailored solutions for specific geological conditions.

Gravel Packing Operations

Medium mesh sizes (30/50, 40/60) with optimal sphericity provide excellent sand control in high-permeability formations while maintaining formation productivity.

Multi-Stage Fracturing

Different mesh sizes and density grades can be strategically deployed in sequential stages to optimise fracture geometry and conductivity distribution.

Key Technical Advantages

  • Comprehensive Product Range: 30+ product variations across 5 mesh sizes (20/40 to 70/140) with 4 crush resistance levels (52-103 MPa)
  • Tailored Density Solutions: Three density categories - Low-density (≤1.50 g/cm³) for reduced settling, Medium-density (1.65-1.8 g/cm³) for balanced performance, High-density (>1.80 g/cm³) for maximum strength
  • Superior Crush Resistance: Withstands closure stresses up to 103 MPa (15,000 psi), enabling deep well applications where conventional sand proppants fail
  • Optimal Sphericity & Roundness: High roundness factor (≥0.85) provides maximum contact throughout hydraulic fractures and enhanced permeability
  • Excellent Size Uniformity: Sieve analysis ≥90% ensures consistent particle size distribution for predictable packing behaviour and permeability
  • Superior Chemical Resistance: Low acid solubility (≤5-7%) ensures long-term stability in acidic downhole environments and extended fracture life
  • Low Crush Rate Performance: Minimal fines generation (3.0-12.0% maximum) ensures sustained fracture conductivity over extended production periods
  • Precision Engineering: Consistent quality control across all parameters with tight specifications for predictable performance in varying downhole conditions
  • Application Flexibility: Complete size range from coarse (20/40) for wide fractures to fine (70/140) for narrow fracture applications and multi-stage treatments

Frequently Asked Questions

What makes ceramic proppants superior to sand proppants?

Ceramic proppants offer crush resistance up to 103 MPa compared to sand's typical 52 MPa, enabling use in deeper, higher-pressure formations. They also provide superior sphericity and uniformity for enhanced conductivity.

Which mesh size should I select for my application?

Mesh size selection depends on fracture width and desired permeability. Larger proppants (20/40) provide higher permeability in wide fractures, while smaller sizes (70/140) are suitable for narrow fractures and specific transport requirements.

What quality standards do your proppants meet?

Our ceramic proppants comply with SY/T5108-2014 Chinese petroleum industry standards and ISO 13503-2 international specifications for hydraulic fracturing proppants, ensuring consistent quality and performance.

How do I determine the appropriate density grade?

Density selection balances transport efficiency with strength requirements. Low-density grades reduce settling and pumping pressure, while high-density options provide maximum crush resistance for extreme downhole conditions.

What is the typical shelf life and storage requirement?

Ceramic proppants have indefinite shelf life when stored in dry conditions. Storage in covered areas away from moisture prevents agglomeration and maintains free-flowing characteristics.
