How are oil and gas reservoirs in the sea identified?
Valuable reservoirs of oil and gas lie hidden in rocks on the seabed, and it can be tapped by drilling through the rocks. But only some kind of rocks contain oil and they must be located in water that is shallow enough for the drilling to reach it. These reservoirs are identified by means of shock waves sent through the seabed and the returning signals distinguish between the rock layers.
