__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.

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.

====Manufacturing ====

A self made engine-driven rotary rig is not very difficult to make, although drill bits, drill pipes and engine may have to be specially imported.

==CostCosts==

The price of these rigs depends and varies between US$ 3000 and US$ 5000.

==Country Field experiences==

Engine operated rotary jetting is mainly used in Thailand, Laos, Cambodia, Chad, Niger, Nigeria, Burkina Faso, Tanzania, Mozambique, Zambia, Mauritania, Madagascar and Nicaragua.
