... ABSTRACT: Migration and packing patterns of proppants play a critical role in the conductivity of hydraulic fractures and unconventional oil and gas production. However, the fracture surface is usually tortuous with gradually narrow walls (tortuous - wedge fractures). Existing fracture models...

The comprehensive model considers hydraulic fracture interaction (i.e., stress shadowing effect), gravity proppant settlement, etc. The numerical results show that the geometry of fracture propagation under the condition of multi-well fracturing completion...

... ABSTRACT: The objective of this study was to examine the effects of various fracturing fluids on proppant transport and its impact on the productivity of a Marcellus shale horizontal well with multiple hydraulic fracture stages. The available data from a Marcellus shale horizontal well were...

... ABSTRACT: In hydraulic fracturing, micro-nano proppants can easily enter microfractures for support and have strong adsorption properties, so it's very important to explore their adsorption in micro-fracture support. By analyzing the forces of the proppant in fractures, a mathematical model...

... due to their cost-effectiveness and simplicity. However, they pose challenges such as formation water sensitivity, blockages, difficulties in transporting proppants, water availability concerns, and issues with cleaning up low-pressure reservoirs. These challenges have spurred research...

... ABSTRACT: The sand-carrying fluid flow in complex hydraulic fracture is crucial to improve the fracture conductivity. Previous research on proppant transportation simulation has mainly focused on planar fracture. This paper presents a proppant transportation model of the nonplanar fracture...

... ABSTRACT: During the post-fracturing flowback stage, a large amount of fracturing fluid (30%-80% of the injected volume) will flow back to the surface, but it will also carry proppants into the wellbore. This has adverse effects on the fracturing effectiveness and subsequent production...

... ABSTRACT: This paper proposes a new low-density, high-strength composite proppant to address the rising cost of proppants in hydraulic fracturing operations in tight oil reservoirs. Fly ash and coal gangue are sintered with a certain concentration of bauxite and alum at 1300°C∼1500°C to form...

... ABSTRACT: The deep-formation rock has various deformation modes such as viscosity, elasticity and plasticity under the action of complex geo-stress, high temperature and high pore pressure. These deformation modes increase the proppant embedment depth at different stages and affect the long...
