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.

1 . A method of gavel-sand well sanding prevention including gravel-pack placement in the well characterized in the fact that as gravel pack proppant represented by polydicyclopentadiene material particles is used. 
     
     
         2 . The method of  claim 1  characterized in the fact that polydicyclopentadiene material particles may be of various shapes. 
     
     
         3 . The method of  claim 2  characterized in the fact that polydicyclopentadiene material particles may be elongated and/or polygonal and/or cubical and/or spherical and/or fiber-like. 
     
     
         4 . The method of  claim 1  characterized in the fact that polydicyclopentadiene proppant may be reinforced using additional filler. 
     
     
         5 . The method of  claim 4  characterized in the fact that the additional filler may be ceramic or silicon dioxide or fiber.
