Scientific drilling into the Earth is a way for scientists to probe the Earth's sediments , crust , and upper mantle. In addition to rock samples, drilling technology can unearth samples of connate fluids and of the subsurface biosphere , mostly microbial life , preserved in drilled samples. Most of the technology used for drilling come from advances in the oil and gas industry. Scientific drilling on the continents includes drilling down into solid ground as well as drilling from small boats on lakes.
