This study is an attempt to investigate the mechanical behavior of proppant packs deforming under compression loading. A generalized confined compression test (CCT) was simulated in the present study to investigate the deformation of walnut/ceramic proppants against compression. In this way, the CCT was simulated using ABAQUS explicit code. Unlike ordinary CCT, we obtained permeability of compr...

The settlement drag coefficient of non-spherical particles (SDCNPs) is a crucial parameter in the field petroleum engineering. Accurately predicting SDCNPs fluid essential to selection and design proppant hydraulic fracturing scheme. Although many models for anticipating have been proposed, none them can be adopted non-Newtonian (NNF) Newtonian (NF). In investigation, NF NNF are studied experim...

The main type of geological and technical measures in the oil fields Western Siberia today is hydraulic fracturing. widespread use this method intensifying production due to its undeniable advantages over other technologies. However, fracturing not without significant drawbacks - clogging bottomhole zone with proppant products chemical reactions, as well premature watering products. All above r...

Proppant flowback after hydraulic fracturing treatment is quite a serious challenge that causes damage to both downhole and surface equipment, leading unwanted workovers production suspension, or other negative outcomes. Some special methods including preventive as well corrective measures already exist in the industry overcome proppant problems. However, there no clear guidance on how choose m...

Micro-fractures are widely developed in deep shale gas reservoirs after fracturing. Effective support of micro-fractures is great significance to slow down the production decline rate Wells. When particles enter fracture, they can be effectively supported provide a channel with high conductivity for oil and transport. The level depends on distribution proppant so it very important analyse descr...

Abstract Horizontal wells are often drilled and hydraulically fractured in tight reservoirs to produce hydrocarbons or heat. Different fracturing fluids such as slick water, gas, foam, gel, a combination can be used with water being the most common fluid. In this paper, we study impacts of different on well productivity using an in-house integrated hydraulic reservoir simulator equation-of-stat...

Survey and novel research data are used in the present study to classify/identify lithological type of Verey age reservoirs’ rocks. It is shown how use X-ray tomography can clarify degree heterogeneity, porosity permeability these These then elaborate a model hydraulic fracturing. The resulting software take into account properties proppant breakdown fluid, thermal reservoir conditions, oil pro...

We study the dynamics of proppants carried by fluid driven into an evolving penny-shaped fracture. The behaviour slurry flow is investigated in two phases: pressurised injection and elastic closure. During modelled using a frictional rheology that takes account shear-induced migration jamming proppants. Making pragmatic assumptions negligible toughness cross-fracture slip, we find self-similar ...
