Median of all compensation (including tips, bonus, and overtime) by years of experience.
In general, experience and pay appear to be strongly linked; those with more experience usually bring in higher incomes. Average salaries for inexperienced employees average out to around $49K, but folks who have five to 10 years of experience earn a higher median of $62K. Petroleum Technicians with one to two decades of relevant experience report an average salary of approximately $83K. Folks who have racked up more than 20 years in the field report incomes that aren't that much higher than less experienced individuals' earnings; the veterans make just $94K on average. Between one and nine years is the typical spectrum of experience for those in this line of work — of those who took the survey, a majority land within it. Experienced employees who have 10-20 years of experience make up nearly one in seven of the workforce; inexperienced individuals who have been working for less than one year comprise less than 10 percent, and senior people with more than 20 years under their belt fill out the remaining nearly one in eight.
