How do Scientists Discover Oil? Part 2
Once geologists have found an area they think may contain oil reservoirs, they turn to several different tools and techniques to ascertain if there really is oil hidden away in the ground below. There are numerous pieces of equipment that can be used in the process of looking for oil. One tactic is to not look but test for the smell of hydrocarbons. These specialized detectors, informally known as sniffers, use ultra-sensitive electronic noses to detect indicators of the presence of hydrocarbons. Another technique is to deploy advance seismic equipment. These machines create special shock waves that are sent down…

How do Scientists Discover Oil? Part 1
Filling up your tank may be an easy thing to do, but the process by which oil is discovered is anything but. The creation of oil is itself an amazing process – beginning with the death millions of years ago of very small plants and animals, with the organisms sinking into and mud. These remains mixed with sediment to form what’s known as source rock. And when the source rock is pressured and heated by new sedimentary layers, it distils the remains of the organisms into natural gas and crude oil. These fossil fuels then shift into what’s called reservoir…
