Question

1)If that strikes oil, then production wells can be drilled.2) They carry out surveys from the ground and from the air using a variety of instruments, and they bore into the rocks to take samples. 3)When Petroleum engineers search for oil they look for certain types of rock layers, or strata which they know from past experience can trap oil. 4) If it indicates that oil may be present, a test well is drilled. 5)Oil is found underground trapped in the layers of rock. 6)When all the information is collected and analysed, a picture of the underground strata is obtained. 7) They also set off explosions in the ground and record the waves reflected from the underground rock layers. 8) This is called seismic surveying​
