[Application]
The primary use of ceramic proppant is in oil and gas well fracturing operations to support fractures, improve reservoir permeability, and increase hydrocarbon production.
[Product Advantages]
1. High strength and corrosion resistance.
2. Lower density helps reduce formation pressure and damage.
3. Excellent permeability and strong resistance to corrosion.
4. Reduce environmental pollution.
[Usage and Dosage]
Dosage should be calculated based on well depth, formation characteristics, and expected fracture length and width.
[Packaging]
Typically packaged in ton bags or bulk. Standard ton bags have a net weight of 1000 kg or 1500 kg. Customized packaging is available upon request.
[Storage Conditions]
Store in a dry, well-ventilated area. Temperature should be below 40°C, and humidity below 80%. Avoid direct sunlight and keep away from fire sources. Prevent dust and contamination; do not mix different models.
