Sample drilling is a process that uses the same equipment like oil and gas drilling, but instead of extracting those resources, it takes samples from underground geologic formations. It has been used for decades to explore new areas or create a map of an area before deciding whether to extract resources.
Drilling is the process of making holes in a surface with a drill, usually using an electric motor. Sample drilling creates small samples from rocks and other earth materials analyzed for various purposes, such as mineral content or oil deposits. It can be used to find natural resources like coal and petroleum, but it is also commonly used by geologists and archaeologists to study the earth’s crust. It has been around since at least 1837 when Henry Shaler Williams invented the first rotary percussion tool (a type of drill).
