Introduction of ceramic proppant

SEPPE Ceramic Proppant

What is ceramic proppant ?

Ceramic proppant is made of high-quality bauxite and other raw materials and sintered with ceramics. Proppant is a solid particle used to prop up the fracture to prevent the fracture from re-closing after the formation has opened the fracture. Therefore, most of the radial flow in the formation is eliminated, and the formation fluid enters the fracture in a linear flow mode. It is an important part of hydraulic fracturing, and its quality directly affects the conductivity of fracturing fractures and the length of validity period, which in turn affects the effects of fracturing stimulation and injection stimulation measures.

What can it be used for ?

Ceramic proppant is a cost-efficitive substitute of natural frac sand. It can be used in oil and gas deep well. In recent years, it has also been widely used in civil architecture, agricultural landscaping and water treatment.

What advantages does it have ?

While ceramic proppants cost more than their naturally-made counterparts, they do offer advantages that make them the preferred choice in some settings, because they are capable of maximizing the yield from a given well. These advantages include:

1.Greater crush strength

As well bores get deeper, the pressure on proppants gets higher, and frac sand is not always up to the task.

Ceramic proppants can withstand a much greater crush strength than traditional frac sand products – up to 10,000 psi.1 This allows drillers to access much deeper shale formations.

2.Higher Conductivity

Ceramic proppants also boast a number of characteristics that translate to better conductivity, or the effectiveness at which the petroleum product can flow around the proppants in the rock fissure.

Improved uniformity in size, shape, and overall sphericity allows natural gas or oil to more easily flow around ceramic proppants in the well bore.

Conductivity is further improved due to the stable thermal and chemical nature of ceramic proppants; there is much less risk for the proppant to thermally or chemically react with the shale formation causing an undesirable deposit to form, which would ultimately clog the fissure.

3.Tailored solutions

Because they are artificial, the characteristics of ceramic proppants can be much more tightly controlled than with sand products. Proppants can be selected based on a variety of engineered characteristics to offer a more tailored solution to the specific needs of a well site.
