Proppants
The most common propping agents include silica sand, treated sand, and ceramics with sizes ranging from 106 μm to 2.36 mm. Resin-coated sand (RCS), is the most commonly used treated sand and is optimal for compressive rock formations. RCS has a lower density and higher strength properties than regular sand but is also more expensive.
