“…As the same to ceramsite, this kind of pre-cured resin coated quartz sand can also be used in deep well fracturing operation under high closure pressure, it could reduce the cost of fracturing and improve oil production rate. Currently, there is seldom research about resin coated sand [7,8]. In this paper, a new kind of resin coated sand proppant has been prepared; and the effects of the resin, firming agent, coupling agent and temperature on proppant's physical and chemical properties have been thoroughly discussed.…”

A method of preparing precured resin coated sand particles was developed. The effects of resins dosages, plasticizer and coupling agent on the sphericity, roundness, crush resistance and flow conductivity of pre-cured resin coated sand were also discussed. Compared with raw sand, the sphericity and roundness of this resin coated sand particles is higher. It also possessed excellent properties to company sample, such as better resistance to crushing, as well as higher short term flow conductivity. By use of the resin coated sand, the cost could be reduced, and the yield of raw oil will be increased. It is a promising method of modified sand in field of hydraulic fracturing treatment.

Hydraulic fracturing is one of the most effective methods for stimulation. At present, it is actively used around the world, as well as in our country, in Kazakhstan. Currently, many producing fields are at their advanced production stage, and new fields are in such geological conditions when hydrocarbons are extracted from tight reservoirs. Hydraulic fracturing allows maintaining the economic profitability of the development of such fields. However, like other stimulation methods, hydraulic fracturing has a number of disadvantages, including proppant flowback. Proppant flowback after hydraulic fracturing treatments is quite serious challenge. This could be the deterioration of the downhole equipment with a subsequent frequent workovers; decrease in well productivity. Some special methods including preventive as well as corrective measures already exist in the industry to overcome the proppant flowback problems. The paper considers systematization of fourteen preventive methods. Based on physical, chemical, and technological properties of each listed method, as well as the knowledge of the main reasons of the proppant flowback the authors systematize all methods and propose an initial decision-making algorithm and a matrix of methods applicability. The algorithm and the matrix were tested under conditions of Uzen field, Kazakhstan. The paper may be of interest to fracturing engineers, production engineers, operation engineers, and other professionals

“…Coated proppant was initially developed to reduce proppant flowback during production, which creates a fracture width reduction due to a loss of proppant at the entrance of the fracture resulting in near wellbore pressure drop. The width reduction can act as a choke limiting production from the entire fracture (Barmatov et al 2008). Proppant that flows back can also have a detrimental effect on production equipment and lead to plugging or erosion of downhole completions.…”

Ultra-deepwater reservoirs are important unconventional reservoirs that have the potential to produce billions of barrels of hydrocarbons, and are usually high pressure and high temperature with relatively high permeability. One major challenge of an unconventional, ultra-deepwater reservoir is pumping an effective and robust fracture stimulation treatment. Hydraulic fracturing a high permeability reservoir (>100 md) can be different from hydraulic fracturing technology used in low permeability formations (<1 md) due to their difference in purpose. The main purpose of hydraulic fracturing a low permeability reservoir is to create a long, conductive path to enhance drainage area and ensure a commericially economic well. In a high permeability formation, hydraulic fracturing is predominantly used to bypass near wellbore formation damage, control sand production and reduce near wellbore pressure drop. Such a treatment is achieved by pumping a short fracture packed with high proppant concentrations and may also aim at achieving enough fracture length to increase productivity especially when reservoir fluid viscosity is high. To pump such a job and ensure long term productivity from the fracture, understanding the behavior of the proppant pack is critical. A series of laboratory experiments have been conducted to study conductivity and fracture width with high proppant loading, high temperature and high pressure using a Cooke conductivity cell. In thisstudy, proppant was manually placed between two core samples and fracture fluid was initially pumped through the proppant pack. Conductivity was subsequently measured by pumping oil through the manuallyplaced proppant pack to displace the fracture fluid and simulate reservoir conditions; resulting fracture fluid clean-up and proppant pack performance were studied. High strength proppant, ideal for fracture stimulations with high closure stress, was used to study the effects of proppant fracture conductivity with different proppant loadings and closure stresses. Proppant crushing and fracture width were also measured and compared to proppant pack conductivity in certain cases. Testing results while pumping oil through the proppant pack at reservoir conditions indicated almost immediate fracture fluid clean-up. Increasing proppant concentration in the fracture showed higherconductivity values in some cases, while increasing the effective closure stress during an individualtest resulted in a significant loss in conductivity for all cases. Additionally, fracture width decreased with increased effective closure stress and time. Tests were also run to study the effect of cyclic loading and showed further degradation in conductivity and width.
