ABSTRACT:
A method is provided for producing at least a first fluid or desired fluid contained in a geological formation this formation further comprising at least a second fluid, or undesired fluid, which risks hindering production of the desired fluid, this latter being produced by means of at least one deflected or substantially horizontal drain.
According to this method, a second drain is disposed in said geological formation, this second drain being situtated between the first drain and the undesired fluid for drawing off a part at least of the undesired fluid and allowing the first drain to produce essentially the desired fluid.
