Abstract
Born in ancient times, drilling wells until the second half of the 19th century remained mostly percussive on rope or rods. Rotary drilling was only manual and was used for sinking shallow wells in weakly cohesive rocks. As far back as 600 years B.C. Confucius wrote of thousands of wells as deep as 500 m and even as deep as 1,200 m drilled in China for water and salt. Over the centuries this ancient invention of the Chinese has hardly changed. French travelers of the 19th century described Chinese drilling technology as it was more than 2.5 thousand years ago.
