                             Black oil frac sand

The high quality bauxite as raw material, High crush resistance and best Roundness

Black oil frac sand is the key material in low-permeability fracturing of oil and gas wells exploration. This products used in the construction of deep well fracturing, be filled to the low permeability of the rock deposits in the cracks, fracturing close to the high oil recovery operations, so that oil and gas cracked rock, support for propping fractures not close because of releasing force, thereby to maintain the high conductivity of oil and gas, not only can increase the oil and gas production output, also can extend the oil and gas wellss length of service.
