Today, most Earth drilling serves one of the following purposes: return samples of the soil and/or rock through which the drill passes; access rocks from which material can ...
Drilling for boreholes was time-consuming and long. As the depth of the holes varied, the drilling of a single well could last nearly one full decade. [4] It was not up until the 19th century that Europe and the West would catch up and rival ancient Chinese borehole drilling technology. [10] [5]
