Abstract
A method and system for lateral drilling with respect to a main well which is cased by a casing string. At least a part of the casing string provides a lateral opening adapted to enable drilling of a lateral well. A guiding device is positioned at a part of the casing string in front of the lateral opening and the guiding device is controlled from the surface of the main well. A lateral casing string equips the lateral well and provided a sub for connecting the lateral casing string to the main string in the main well.
