| abstract | A method of controlling sand production in a sandstone reservoir comprising providing (i) an aminosilane and (ii) a polymeric linking agent comprising monomeric units having pendent functional groups selected from the group consisting of carboxylic acids, carboxylic acid esters and amides, wherein a plurality of the pendent functional groups are reacted with the amino group of the aminosilane by a process selected from the group consisting of aminolysis of carboxylic acid ester groups, Mannich reaction between the amino group of the aminosilane and a plurality of at least one of carboxylic acid and amide pendent groups in the presence of an aldehyde activating agent or combination thereof, contacting the aminosilane and polymeric linking agent with the sandstone reservoir to bond the silane group of the aminosilane with particles of sand and provide agglomeration as a result of covalent bonding of the linking agent with a plurality of aminosilanes. |
