PROPPANTS WITH IMPROVED STRENGTH

Cements, such as alkali activated aluminosilicate, may be used as coatings on proppants, such as brown sand and white sand, to improve the strength thereof. The resulting coated proppants show increased strength as well as produced fines of lower than about 10 wt% at 10,000 psi closure stress. Selon...

Zusammenfassung:	Cements, such as alkali activated aluminosilicate, may be used as coatings on proppants, such as brown sand and white sand, to improve the strength thereof. The resulting coated proppants show increased strength as well as produced fines of lower than about 10 wt% at 10,000 psi closure stress. Selon l'invention, des ciments, tels que l'aluminosilicate activé par des alcalis, peuvent être utilisés comme revêtements sur des agents de soutènement, tels que du sable brun ou du sable blanc, afin d'améliorer la résistance de ceux-ci. Les agents de soutènement revêtus obtenus présentent une résistance accrue, ainsi que de fines inférieures à environ 10% en poids à une contrainte de fermeture de 10.000 psi.
