<p>A flexible hose assembly (10) for horizontal well drilling is provided. The flexible hose assembly (10) has a number of spaced thruster couplings (12) along its length to impart drilling force to a nozzle blaster (24) at an end of the flexible hose (11). The thruster couplings (12) have rearwardly oriented holes (18) which impart a forward drilling force upon the exit of high pressure water through the holes (18). A method of horizontal well drilling using the above-described flexible hose is also provided. The method is particularly useful for shallow wells, such as 50-2000 feet.</p> |
