__NOTOC__

Engine powered rotary jetting is a [[Jetting - general| jetting technique]] in which engine power is used to rotate the drill stem and pump the mud. A large variety of engine powered rotary jetting rigs are used. Examples of commercial versions used in developing countries are the Lone Star 100, the PAT Drill 201 and the Deep Rock Hydra drill; but many more exist.

Although one would expect a large advantage over manual jetting, engine operated rotary jetting requires the same time and reaches the same depths as the manual operated rotary jetting. The systems show better performance only with regard to ergonomic aspects.
