A method for improving underground fluid collection and removal. The method includes drilling one well (20) with a vertical section and a horizontal section (40) having main bores and branches. All the branches are substantially in one horizontal plane except one branch for each main bore. That one branch (140) for each main bore is slope downward towards a common place, where a second vertical well is drilled for collecting fluid.
L'invention concerne un procédé permettant d'améliorer la récupération et l'évacuation d'un fluide souterrain. Ce procédé consiste à creuser un puits comportant une section verticale et une section horizontale comprenant des orifices principaux et des ramifications. Toutes ces ramifications sont situées dans un même plan horizontal, excepté une ramification. Cette ramification pour chaque orifice principal est inclinée vers le bas vers un point commun où un second puits vertical est creusé pour récupérer le fluide. L'invention concerne également un système découlant de ce procédé.
