ABSTRACT:
The present invention resides in a three directional horizontal drilling process which is suitable for the in-situ treatment or extraction of undesirable contaminants from subsurface formations. A first extraction well is drilled utilizing three directional horizontal drilling techniques in the general vicinity of a contaminated subsurface formation. A second injection well is strategically drilled to direct contaminants into a subsurface screen system in the extraction well, thus facilitating the extraction and collection of undesirable contaminants.
