Studies of Fracture Damage Caused by the Proppant Embedment Phenomenon in Shale Rock
This paper concerns the effect of proppant embedment related to hydraulic fracturing treatment. This phenomenon occurs if the strength of a dry reservoir rock is lower than that of proppant grains. The aim of this research was the laboratory determination of the loss of width of the proppant pack bu...
