The driling manual / Руководство по бурению

Drilling occurs in all nations around the world, and in the seas surrounding those nations, using drilling rigs to bore into the earth.
Drilling:

• provides information about resources (minerals, construction material, oil, gas, water) and also provides access to those resources.

• helps with developing infrastructure in foundations, piling, and constructing dams, and in laying underground cables for energy transmission and  communications.
• helps to gather information such as ground strength, ground formations and composition, and the presence and quality of groundwater (geotechnical, seismic, and environmental).
The drilling industry contributes more than its expected share to a nation’s economy, because it supports a number of other industries – construction and infrastructure development, mining, energy supply (oil, gas, coal, hydro-electricity and geothermal) and housing, agriculture, and rural development through groundwater supply <...>
