The geologist's job is to observe, explore and scrupulously record any clue to the possible presence of hydrocarbons below ground. Geologists are people of action and naturalists. They examine rocks and take samples to ascertain their nature and date the strata from which they were taken. They then seek to reconstitute a scenario that may have been written 4 billion years ago.
