Nettet4: Hydraulic Fracturing. Developed in the 1940s, the process of hydraulic fracturing has become increasingly important in oil drilling. It comes in handy with "tight" reservoirs -- where the rocks containing the oil don’t have large pores. This means that the oil flow from the rocks is weak, and drilling a simple well into the rock won’t ... NettetModern oil geologists also examine surface rocks and terrain, with the additional help of satellite images. However, they also use a variety of other methods to find oil. They can use sensitive gravity meters to measure tiny changes in the Earth's gravitational field …
