Drilling techniques

Definition

Drilling techniques refer to the methods and technologies used to create boreholes in the earth's surface to extract mineral and energy resources. These techniques are crucial in exploration and extraction processes, allowing geophysicists and engineers to gather subsurface data, locate valuable resources like oil, natural gas, and minerals, and assess their viability for extraction. The effectiveness of these methods significantly impacts the success rate of resource exploration and ultimately influences economic growth and energy production.
