Studies of Fracture Damage Caused by Proppant Embedment Phenomenon in Shale Rock [PDF]
Applied Sciences, 2019 This paper concerns the effect of proppant embedment related with hydraulic fracturing treatment. This phenomenon occurs if the strength of the reservoir rock is lower than proppant grains. The aim of the research is laboratory determining the loss of width of the proppant pack built of light ceramic grains.

Reversible watermarking scheme with image-independent embedding capacity [PDF]
, 2005 Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,

Numerical Simulation Of Horizontal Migration Of Proppant
, 2008 The horizontal migration of proppant was numerically investigated with a two-fluid model, in which the interaction between fracturing fluid and proppant, along with that among proppants was taken into account through interphase forces.

Proppant embedment in coal and shale: Impacts of stress hardening and sorption
International Journal of Coal Geology, 2020 Abstract During methane production in CBM reservoirs, the influence of proppant embedment and permeability damage cannot be neglected – especially where the wall-rock is soft. Effective stresses are elevated during methane recovery, increasing both normal loading stress and confinement and simultaneously overprinting sorption-induced volumetric ...
