Course Description

The most universal, comprehensive and concise descriptive documents on oil and gas wells are logs. They impact the work of almost every oilfield group from geologists to roustabouts to bankers. Familiarity with the purposes and optimum applications of well logs is therefore essential for people forging their careers in the oil business
