Ceramic proppants come in different anti crushing strengths and sizes

Other types of proppants like sand or sand-based might be cheaper, but both engineering study and real oil and gas production experiences show that ceramic proppants provide higher and consistent oil and gas production rate due to their higher strength, uniformed sizes and shapes regardless in the shapes of reservoirs and their conditions. Ceramic Proppant grains with uniform size and shape has great advantage of providing maximum porosity for the oil and gas flow channel and allows more oil and gas flow the proppant pack.
Ceramic proppants come in different anti crushing strengths and sizes, and can be classified as into middle ranged density ceramic proppants, mid to high density ceramic proppants. Each group has different ranges of anti-crushing strength.
