The application of hydraulic fracturing stimulation technology to improve the productivity of
unconventional oil and gas reservoirs is a well-established practice. With the increasing …

Proppant is the key material of hydraulic fracturing, which directly determines the fracturing
effect of hydraulic fracturing. With the gradual development of unconventional oil and gas …

Conventional proppants have the problem of proppant flowback and the inability to fully
distribute along long fractures. To solve these problems, coated proppants have emerged …

Oil well stimulation treatments have been employed to improve the productivity index, either
by imposing a negative skin effect through hydraulic fracturing or by reducing a positive skin …

Herein, we report mechanically reinforced dual-coated sand proppants for hydraulic
fracturing operations. The dual-coated sand proppants were prepared by sequential surface …

Fracturing (hydraulic fracturing technology) treatment in an unconventional reservoir was a
key technology. For an increased in production, effective proppant placement in hydraulic …

Controlling scale deposition in tight formations such as shale is commonly achieved by
combining fracturing stimulation with squeeze treatment. The squeeze treatment process's …

The present work reports the fabrication of ultra-high strength microsand proppants (100
mesh) through a polymer nanocomposite dual coating approach and gives insight into their …

The present work reports 3D-cross-linked polymer network-based coating onto frac sand
prior to the epoxy coating to prepare dual-coated sand proppants with very high-stress …

Proppants play an important role to increase oil and gas output in shale oil and gas
development process. Tracers are used to study the degree of heterogeneity and dynamic …
