The salaries of petroleum geologists correspond to their years of experience, according to the 2012 salary survey released by the American Association of Petroleum Geology. For example, workers with up to two years of experience averaged $98,700 per year, with a high of $110,000, and a low of $85,000.
Geologists in the United States can expect to earn an average of $61K per year. Total cash compensation for Geologists runs from $40K to $131K depending on bonuses that can occasionally exceed $25K and profit sharing that can reach almost $29K. The most influential factor affecting pay for this group is the company, though the particular city and years of experience have a (lesser) impact as well.
