Relationship with crude oil proppant acidification of compatibility

In the production of oil proppant time, another serious problem is the reaction of formation fluid is crude oil with an acid to remove residual oil phase can increase the effectiveness of the acid system. Some oils, in particular black heavy oil (<30'APl) and an acid or acid forming slag (precipitated asphalt), either to form a stable emulsion. Moore et al (1965) reported the problem, and give a solution. Sometimes slag breaker agent and does not prevent the formation of a stable emulsion formation. Houchin and Hudmn (1986) discussed similar issues exist organic deposition. Recent resin coated proppant studies have shown, how to prevent the reaction of the acid and the crude acid residue and more stable emulsion. Some "difficult" crude oil between the crude oil and the need to use a hydrocarbon solvent, an acid buffer, crude oil, and the acid can be miscible. Buffers to reduce exposure of crude oil and an acid, and prevent or reduce the acid sludge and emulsion problems. This technique, In Wyoming oilfield construction will increase the success rate from 25% to 75%.
Due to the pressure drop, the asphalt particles will settle. Mutual solvent can be used to partially or completely ceramic proppant disperse them. This action will help to better dissolve the acid-soluble acid solid. To an already oil-based mud competing well well before acidified with an aromatic hydrocarbon solvent pre-soaked conducive flowback. Formulations mutual solvent and surfactant solution can be used as a pre-rinse solution, to restore the formation of water-wet condition.
reported the use co, as a pre-construction solution on acidification has many benefits, helps to reduce the amount of acid to achieve the desired success increase. This type of solution has been demonstrated in the pre-core studies, can improve oil displacement efficiency and improve the flow of the oil.
            

Ceramsite proppant, production method

ceramic proppant is oil, natural gas extraction in the process of fracturing operation to support the solid particles of rock joints with certain strength.

  During the fracturing operation process, proppant mixed with fracturing, using high pressure means will be injected into the deep rock crevices, forming high permeability channel, so that the oil or gas outflow from the cracks.

  The practice proved that, the use of high aluminum proppant fracturing wells can increase the yield of 30 ~ 50%, the service life can be extended well.

Proppant testing becomes more important

Frac proppantis to crack open after lamination, for supporting the fracture to prevent fracture closure of a solid particle. It is an important part of hydraulic fracturing, its quality directly affects the size and the length of validity of fracture conductivity, thereby affecting the fracture stimulation effect. Thus proppant testing becomes more important
 

Hydraulic Fracturing Proppants has become the main measures of well stimulation

Hydraulic Fracturing Proppants technology has become the main measures of well stimulation, it has been widely used in the development of various oil and gas fields, of which an important part of the proppants for hydraulic fracturing, obtained many breakthroughs, especially in low permeability oil and gas development period today, proppant improve performance so that hydraulic fracturing stimulation effect increased significantly.

Ceramic ball are widely used in natural gas fracturing

Ceramic ball are widely used in petroleum, chemical, fertilizer,natural gas fracturing and environmental protection industries. As the reactor coverage tower packing proppants and catalyst. It has a high temperature high pressure, low water absorption,chemical stability characteristics. Can withstand acid, alkali and other corrosive organic solvents and can withstand temperatures occur during the production changes. Its main role is to increase the gas or liquid distribution points, support and protect the strength is not high activity catalyst.

Hydraulic fracking technology development

Hydraulic fracking technology originated in the United States, it is the main method of shale gas exploration and development. Application of hydraulic fracturing technology can greatly improve the unconventional natural gas  production, the application of the principle is to participate chemicals into the water poured into the hydraulic fracture shale gas reservoir, thereby releasing the gas. With the large-scale commercial development of unconventional oil and gas resources, hydraulic fracturing technology must be large-scale application.
           

Kind of oil well fracking

Kind of oil well fracking

(1) hydraulic fracking, mainly by changing the state of the fluid flow, reduce energy consumption and reduce the formation of fluid flow near the lower resistance to complete. So that it can inject the proppant to achieve the diversion effect, so that the oil production.

(2) high energy gas fracturing, boosted by rapid cracks, such cracks are not easily closed during the generation of cracks naturally there will be some debris off, these chips will be self-supporting from the cracks. Meanwhile, in a high temperature wax soluble pores, resin and asphaltene, high temperature can make crude oil viscosity reduction.

(3) acid fracturing ,it is the acid as a fracturing fluid without proppant fracturing.
