Core Samples Provide Insight into Hidden Reservoirs
Although oil and gas initially formed millions of years in the past, it does not remain in the same place. Instead, it moves around through rocks until it reaches a barrier, often referred to as a trap. (Traps, typically comprised of layers of rock, prevent oil and gas from reaching the top of the earth’s surface.) Such traps are typically categorized according to their appearance or how they were formed.
While it would certainly be nice if oil and gas research companies could see beneath the surface of the earth in order to locate pockets of oil and gas, which simply is not currently possible. As a result, it is necessary to use other techniques in order to acquire a picture of where natural gas and crude oil deposits may be located. Core samples for research are often at the forefront of this exploration process by providing critical information regarding the makeup of the rock that will need to be drilled as well as potential oil and gas level estimates based on the core samples provided.
