Dyna Drill history

There are some inventions at the End of the 18th century which proposed a drive mechanism at the end of the drill ​​ driven by the drilling fluid, like the turbine drive for diamond drill bits from 1873 by Christopher G. Cross ​​.

Howard Robard Hughes invented the roller cone bit om 1908, this was the breakthrough for rotary drilling and made the later invention of the tricone carbide insert drill bit possible.

In 1930, John Adolphus Zublin patented a fluid driven hammer mechanism ​​. The patent consists of multiple mechanisms to convert the hydraulic energy to a percussive motion and some possible piston retraction concepts.

Dyna-Drill Technologies has been supplying the oil and gas industry with down hole motor equipment made to withstand your most demanding applications since 1958.

The invention of a new kind of hydraulic percussion drill at Pan American Petroleum Corp. (later known as Amoco, then BP) by Renic P. Vincent in 1968 was another milestone.

Novatek patented a new mud driven percussion dill in 1989 ​​, placing the valve around the striking piston and using a hydraulic circuit parallel to the drilling mud flow.
