Oils and Gas Are Often Found Together Oil is a liquid Gas is in a gaseous (invisible) state – like air Oil and gas move through sand as a team
Where Do Oil and Gas Come From? Microscopic View GasOil Water Source Rock (Fossils) Oil drops in grains of sand

Tools used to find oil
Initially oil and natural gas exploration was as simple as locating surface seeps or places where oil and gas had been discovered accidentally while digging or drilling for water.
Tools used to find oil Seismology, like echolocation, uses vibration and reflection to locate the seams between geographic layers. vibroseis trucks
Tools used to find oil Off-shore seismology
Tools used to find oil Geologist can study aerial photographs and images from satellites.
Tools used to find oil Outcrop surveys
Tools used to find oil Data regarding magnetic fields, gravity and radiation are collected and analyzed

How do oil and gas get from the ground into products we use?
2. Drilling and Production Engineers use the geology map to drill a well under the Earth’s surface using a “rig” If successful, the well will bring a steady flow of oil and gas to the surface m/oil-and-gas-traps/
. The only way to know for sure is to drill… 2. Drilling and Production
Production Or in the case of coal, to dig…
Extraction of Gas and Oil After the rig is removed, a pump is placed on the well head. An electric motor drives a gear box that moves a lever. The lever pushes and pulls, forcing the pump up and down, and creates a suction that draws up the oil.

4. Transportation Crude oil, coal and refined products are transported across the water in barges and tankers. On land crude oil and products are moved using pipelines, trucks, and trains. Photo above courtesy of BP
5. Refining Crude oil is a mixture. Remember mixtures? Refining is separating the components of the mixture.
