Finding Oil - Geophysical Surveys

One of the ways that oil prospectors find oil is with a geophysical survey. A geophysical survey is sonar for the ground. Surveyors send vibrations deep into the earth, sometimes as deep as 30,000 feet down. Each layer of rock shows surveyors a different reading until a liquid is found somewhere deep in the earth. Surveyors can tell how far the oil is into the ground and roughly how much of it there is before they start drilling. In many ways, geophysical surveys are the most accurate and useful way to find oil deep in the earth. Other ways of finding oil include wildcatting, in which oil wells are drilled on untapped oil fields in search of a large oil reserve. This method is considered high risk, high reward because it doesn’t cost as much, and the payoff could be huge, but drilling without knowing where the oil is exactly is always a risky operation. Oil prospectors can also take detailed pictures of an oil field with a satellite. The pictures are analyzed by geological experts to determine if a given oil field can is productive.

Geophysical surveys also involve sensors that detect other telltale signs of oil deep in the earth. Devices meant to detect changes in magnetism are used to find the exact location of the oil.

Brian Sullivan Fairfield Energy, former leader of Fairfield Energy, only worked in oil fields that he knows will produce. Sullivan uses all of the tools at his disposal to find the most productive oil fields for his company, himself and his partners.
