Title (EN) DOWNHOLE MATERIAL DELIVERY
(FR) DISTRIBUTION DE MATÉRIAU EN FOND DE TROU
Abstract:
(EN) A method of delivering material, typically lost circulation material (LCM), into a hole via a tubular string comprises: opening a bypass port (32) in a tubular string located in a drilled hole, the bypass port being provided above fluid outlets (28) in the distal end of the string,- delivering material through the string from surface, the material passing through the bypass port and into the drilled hole; and locking a volume of fluid in the string between the bypass port and the fluid outlets such that fluid is prevented from passing from the hole into the string via the fluid outlets.
(FR) L'invention concerne un procédé de distribution de matériau, généralement de colmatant (LCM), dans un trou via une rame tubulaire. Ledit procédé consiste: à ouvrir un orifice de dérivation dans une rame tubulaire placée dans un trou foré, l'orifice de dérivation étant formé au-dessus de sorties de fluide à l'extrémité distale de la rame; à distribuer le matériau dans la rame depuis la surface, le matériau passant par l'orifice de dérivation et dans le trou foré; et à bloquer un volume de liquide dans la rame entre l'orifice de dérivation et les sorties de liquide de sorte que le passage du liquide de l'orifice vers la rame via les sorties de liquide est empêché.
