Abstract
Les réalisations décrites comprennent un appareil, comme un piston plongeur pour les puits de pétrole et/ou de gaz, qui comprend au moins une caractéristique de décapage. La caractéristique de décapage peut comprendre au moins une crête configurée pour décaper du matériel, comme les paraffines, les asphaltènes, le sel, les hydrates, les débris et les solides, de la surface interne dun corps tubulaire et déloigner le matériel décapé du corps du piston plongeur. Une méthode décrite servant à décaper du matériel à lintérieur dun corps tubulaire comprend introduire un piston plongeur dans le corps tubulaire qui comprend une surface externe ayant une caractéristique de décapage qui comprend au moins une crête, décaper le matériel sur la surface interne du corps tubulaire au moyen de la crête de la caractéristique de décapage et éloigner le matériel décapé du corps du piston plongeur.
