Abstract: A drill assembly with a drill body coupled to a drilling string and a sonde body having a least one chamber defined therein for receiving locating electronics therein. In disclosed embodiment, the one or more chambers may be provided and the electronics can include a battery, a sensor, a transmitter, an antenna and connecting wires. One or more secure windows may be provided in the sonde body to allow the locating electronics to wirelessly transmit outside of the sonde body. The electronics may be potted within the chamber with a solidifying potting agent to improve durability of the electronics in a drilling environment.

Abstract: A system and method for installing casing in a blind horizontal well for blind horizontal directional borings. The system and method may include an example of an offset transmitter sonde assembly that contains an open central passage through which well casing can be inserted, and an example of a drill bit assembly that may be remotely uncoupled from a drill string, leaving the bit in the bore created. Remote uncoupling of the drill bit assembly tends to allow a casing to be installed in the bore while the drill string and bit remain in the bore for support during casing installation. After installation of the casing the drill bit assembly may be uncoupled from the drill string, allowing the drill string to be withdrawn from the bore, with the drill bit assembly remaining in the bore.

Abstract: A system for a water supply well that incorporates a vertical well with one or more horizontally drilled collectors extending therefrom. All of the horizontally drilled collectors may be constructed using horizontal directional drilling techniques with the main drilling equipment positioned on the ground surface and thereby defining a surface port for accessing the horizontal collector. The horizontal collector may be cleaned and maintained through the surface port without requiring access through the vertical well.
