摘要

Low density propante for sustaining fractures induced in rock formations subterru00e1neas and packaging devices for retaining the sand formation.The present invention provides a material for filling fractures obtained by means of hydraulic fracturing operations, as well as filling the annular space between the shaft and the screens or between shaft and tubes scored in the operations of "back pack.Propante based on coconut shell of macauba, industrialized, crushed and sieved, and receive or not, a treatment based on resin to increase the mechanical strength and the decrease of solubility in hydrochloric acid, hydrofluoric acid, or a combination of the two, presenting the mat Erial of this invention.The density and mechanical strength characteristics suitable for sustaining fractures or packaging 1 fill "taped packs".
