Proppant Frequently Asked Questions

1   Proppant   how to use  What is the role
A: The fracturing fluid additives are mixed together and pumped into the formation, cracks, and to bring to the seam proppant, proppant flowback after the crack opening. Corresponding costs ratio: 46% fluid infusion, 25% proppant fracturing chemicals accounted for 19%, 10% acid.
The role of proppant in the fracture after cracks open, so its strength is critical proppant must be sufficient to withstand the closure pressure.
 
2  Ceramic proppant  of raw materials and Scope
A: It is based on sintered bauxite and other additives, and its mineral components are alumina, silicates and iron - titanium oxide, more spherical cylindrical, high strength, high closing pressure for deep oil and gas layer fracturing, for the deep well, to improve the flow capacity is also used to make trailing proppant.
 
3 The amount of fracturing a well ceramisite
Answer: According to the calculation of the length and width of cracks. Generally 30-40 square, large amount of up to one hundred sixty seventy square.
 
4 ceramic performance impact fracture conductivity of the main factors
A: (1) density.  ceramic proppant  fracturing fluid density will affect the choice; (2) sphericity. Proppant particle shape directly affect the flow capacity; (3) Broken rate. Crushed under the pressure of a certain closure rate is lower (higher strength) diversion capacity of the stronger; (4) acid solubility. Acid solubility is lower (the stronger acid), the higher the conductivity.
 
5  fracturing  fluid and the oil will be pumped together
A: There will be a small part of the process because there is flowback, most fracturing fluid flowback will be up, but very few will be left in the ground or have been drawn up and the oil together, but also through post-processing of oil, so not affected.
