Opis:: To increase the efficiency of fracturing process, proppant materials are added to fracking fluid. This admixture allows to keep developed fracks, that tend to lock, opened. The aim of this overview is to present methods of carbon dioxide and proppant mixing. The most often applied methods are as follows: special medium admixing, direct proppant with CO2 mixing. Liquid CO2 and proppant blenders are currently commercially used, but are not very popular.

Opis:: Throughout the past two decades, there has been a great intensification of research on processes related to hydraulic fracturing. One of the most significant issues is the behavior of proppants under reservoir conditions. It clearly influences the oil production from the stimulated borehole. Quick loss of a fracture conductivity after hydraulic fracturing may be caused by migration of particles into the porous area of the fracture. Another effect is creation of small solid particles as a result of proppant crushing. Mineral sedimentation may occur on grains propping the fracture because of chemical reactions at the area of contact between the proppant and the mixture of reservoir water and the fracturing fluid. The effect of these reactions is changes in the porosity of the proppant package and conductivity of the fracture. The article presents results of a computer simulation of parameter changes of the proppant in reservoir conditions and their influence on oil production. One of paramount factors is proppant grains damage. As a result of a computer simulation, using Fracpro software, the level of decreased conductivity of the fracture was determined. It was also defined that the influence of this phenomenon on lower production in comparison to the situation where proppant damage is not accounted for.

Tytuł:: Influence of proppant concentration on rheological parameters of slick water

Opis:: Proppant concentration is one of the main parameters used to design, characterize and describe hydraulic fracturing process, as well as properties of proppant transport and fracturing fluid such as viscosity and viscoelasticity. Low viscosity fracturing fluids decrease proppant transport capability while high viscosity fracturing fluids increase pumping time, proppant transport properties and also the fracture width. A larger proppant size leads to a high permeability of the reservoirs while applying a low stress closure but it requires enough large fracture width to be transported during the process. So combining those parameters in a right way will lead to the achievement of a high performance hydraulic fracturing process. The goal of this paper is to analyze the influence of proppant concentration addition on rheological properties of hydraulic fracturing fluid, using slick water and sand proppant; rheological models are reviewed, and based on the experimental values of different proppant concentrations, the best rheological model describing this process has been chosen based on the best fit curve. A new approach based model is developed in the way of well describing the hydraulic fracturing process. Details are given of the important properties related to hydraulic fracturing fluid. Lab testing results are presented as support to observations made.
