Brown Fused Alumina as a Frac Sand Alternative
High-strength proppant option for hydraulic fracturing under extreme pressure and temperature.
Why Use BFA as Proppant in Fracturing?
Brown fused alumina (BFA) is a viable ceramic alternative to conventional frac sand, especially in deep well operations. Its superior crush resistance, thermal stability, and sphericity make it an excellent candidate to maintain permeability and conductivity under closure stresses beyond 10,000 psi.
- Crush resistance > 12,000 psi (per API RP 56/60)
- Low dust, low fines generation, minimal embedment
- Inert alumina structure ensures corrosion resistance
Applications in Unconventional Wells
- High-pressure hydraulic fracturing in shale formations
- Deep horizontal wells and HPHT wells
- Gas, oil, and geothermal reservoir stimulation
BFA performs where conventional frac sand or resin-coated sand may fail due to particle breakdown or embedment into formation rock.
