Oil and gas exploration, or commonly called as hydrocarbon explorations is the term used by geologists to look for oil and natural gas. The exploration allows oil and mining companies to harvest natural gas and hydrocarbons from different parts of the earth. Drilling is expensive and as such hydrocarbon explorations are done to identify possible areas which contain these deposits while limiting cost and reducing its impact on the environment.
Before a drill location is identified, geologists must evaluate the area and ensure that five factors are present – source rock, reservoir, migration, trap and seal or cap rock. As explorations are expensive and costly, these factors must be present before any drilling is done. Once the factors are considered, geologists employ several techniques to ensure the success of the drilling. The first methodology involves geophysical survey or seismic survey. This process includes the measurement of electrical currents, … Read More
