Title (EN) METHOD FOR SEALING PERFORATION TUNNELS WITH SWELLING ELASTOMER MATERIAL
(FR) PROCÉDÉ DE SCELLEMENT DE TUNNELS DE PERFORATION AVEC UN MATÉRIAU ÉLASTOMÈRE GONFLANT
Abstract:
(EN) A method for sealing perforation tunnels in a well includes steps of pumping an initial volume of fluid into the well, mixing expandable material into a carrier fluid to form an expandable fluid mixture, pumping the expandable fluid mixture into the well to force the expandable material into the perforation tunnels in the well, and holding the expandable material under a hold pressure in the perforation tunnels for a cure period to form perforation plugs.
(FR) Cette invention concerne un procédé de scellement de tunnels de perforation dans un puits, comprenant les étapes consistant à pomper un volume initial de fluide dans le puits, mélanger un matériau expansible dans un fluide porteur pour former un mélange fluide expansible, pomper le mélange de fluide expansible dans le puits pour forcer le matériau expansible dans les tunnels de perforation dans le puits, et maintenir le matériau expansible sous une pression de maintien dans les tunnels de perforation pendant une période de durcissement afin de former des bouchons de perforation.
