In Wanli R & D center, we have professional labs for physical and chemistry testing. With years of development, the center has improved methods for test and research, which makes great contribution to the technological updating. The products made by Wanli have successively passed tests of the authentication of Reservoir Stimulation Laboratory of RIPED-Langfang Petrochina, Stim-Lab and Frac-tech Lab and win the certificate of API, which guarantees the leading position of our technology in domestic industry.

Our company took six years to absorb, apply and re-innovate the technology, and developed light weight & ultra-light weight ceramic proppant, etc. The proppant is the key material in low-permeability fracturing of oil and gas wells' exploration. This product is used in the construction of deep well fracturing. Ceramic Proppant is filled to the low permeability deposit in the crack of rock stratum, in order to crack the rock of oil and gas, and propping the fractures not to be closed because of the released force when extracting oil by high closed fracturing, thereby to maintain the high conductivity of oil and gas.

Our proppant features superior thermal stability, high pressure resistance, erosion resistance and high conductivity, satisfying the demands of hydraulic fracturing in different conditions.

Our oil ceramic proppant can be classified as follows:

By compression strength: 52MPa (7500psi) 69MPa (10000psi) 86MPa (12500psi) 103MPa (15000psi)

By bulk density: light density, medium density, high density.

By specification: 6-12 mesh 8-16 mesh 12-18 mesh 12-20 mesh 16-20 mesh 16-30 mesh 20-40 mesh 30-50 mesh 30-60 mesh 40-60 mesh 40-70 mesh 70-140 mesh etc

Moreover, we can produce products with different specifications according to client’s particular requirements.

Ceramic proppant is the key material in low-permeability fracturing of oil and gas wells exploration. It is 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 wells length of service.
