Abstract
A flexible hose assembly for horizontal well drilling is provided. The flexible hose assembly has a number of spaced thruster couplings along its length to impart drilling force to a nozzle blaster at an end of the flexible hose. The thruster couplings have rearwardly oriented holes which impart a forward drilling force upon the exit of high pressure water through the holes. 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.
