Subsurface Data in the Oil and Gas Industry
Introduction. Drilling for oil and gas is expensive. A single well generally costs $5-8 million onshore and $100-200 million or more in deep water. 1 To maximize the chances of drilling a productive well, oil and gas companies collect and study large amounts of information about the Earth's subsurface both before and during drilling. Data are collected at a …
