Abstract
A method for constructing a lateral hole (303) departing from a main well (302) at a determined depth, the lateral hole (303) having a direction of elongation forming a determined angle with the main well (302), comprises positioning a drilling machine (301) at the determined depth in the main well (302), drilling the lateral hole (303) departing from a wall of the main well (302), in substantially the direction of elongation forming the determined angle with the main well (302), using the drilling machine (301), constructing a tubular (305) for the lateral hole (303) at a downhole location, and positioning the constructed tubular (305) into the lateral hole (303).

A method for constructing a lateral hole departing from a main well at a determined depth, the lateral hole having a direction of elongation forming a determined angle with the main well, the method comprising:
- positioning a drilling machine at the determined depth in the main well (21);
- drilling the lateral hole departing from a wall of the main well, in substantially the direction of elongation forming the determined angle with the main well, using the drilling machine (22);
- constructing a tubular for the lateral hole at a downhole location (23);
- positioning the constructed tubular into the lateral hole (24).
A drilling machine (301, 601, 901, 1001) for constructing a lateral hole (303, 603, 903, 1003) departing from a main well (302, 602, 902, 1002) at a determined depth, the lateral hole (303, 603, 903, 1003) having a direction of elongation forming a determined angle with the main well (302, 602, 902, 1002), the drilling machine (301, 601, 901, 1001) comprising:
- drilling means (307, 607, 907, 1007) to drill the lateral hole (303, 603, 903, 1003), departing at the determined depth from a wall of the main well (302, 602, 902, 1002), in substantially the direction of elongation forming the determined angle with the main well (302, 602, 902, 1002);
- constructing means (315, 616, 915, 1015) to construct a tubular (305, 605, 905, 1005) for the lateral hole (303, 603, 903, 1003) at a downhole location;
- positioning means (313, 613, 913, 1013) to position the constructed tubular in the lateral hole (303, 603, 903, 1003).
