Abstract
The present invention provides a method for injecting a fluid into a geological formation so as to form a barrier of said fluid along a predetermined surface having an elongate shape, the direction of elongation of this surface, or main direction, being distinct from the vertical. Said method consists in injecting said fluid from at least one injection zone of at least one drain passing through said formation, said injection zone being sloping with respect to the vertical and belonging substantially to the surface of the barrier to be formed.
