Method to prevent well sanding using gravel packing

Abstract

The invention is related to the methods of well sanding prevention, particularly to the technologies of gravel pack making, and may be used for underground formations treatment, particularly for the operations to prevent sand inrush from the oil formation into the well. The sanding prevention method includes placement of the gravel pack in the well where polydicyclopentadiene material is used as the gravel pack. The method enables better sand and fines filtration through a denser and more uniform distribution of the gravel pack as polydicyclopentadiene material, its high thermal stability and high crushing strength.
