Hydraulic fracturing is used in the oil and gas industry

Hydraulic fracturing is used in the oil and gas industry to increase the flow of oil and/or gas from a well. The producing formation is fractured open using hydraulic pressure and then proppants (propping agents) are pumped into the oil well with fracturing fluid to hold the fissures open so that the natural gas or crude oil can flow up the well. The hydraulic fracturing proppant size, shape, and mechanical strength influences the integrity of the newly created fractures, and therefore the flow of oil and gas out of the well.

What ceramic sand is ?

ceramic ball , is used to replace concrete gravel and pebbles , is the use of a variety of materials of various types of clay, slate , shale , coal , and industrial solid waste , etc., through the ceramic sintering.
Ceramic sand has a low density , excellent thermal insulation , impermeability, excellent alkali aggregate reactivity, low water absorption, frost resistance and good durability , and many other advantages. hydraulic fracturing proppant, by definition, ceramic particles , called fine sand , also known as oil fracturing proppant .
Most circular or oval sphere, but some ceramic imitation gravel is not circular or oval sphere, and irregular shaped gravel . The appearance of color due to different ceramic materials and process used and different. Firing ceramic colors are mostly dark red , red ocher , there are some special varieties of pale yellow , gray and black ceramic proppant sand , gray , blue gray and so on.
