Petroleum engineers design methods for extracting gas and oil deposits from below the Earth's surface. Once these reservoirs are discovered, petroleum engineers work with specialists on discovering the formation of the rock, methods of how to drill down to the reservoir, and how to monitor the drilling. They also design the equipment and process that gets the maximum profit from the gas or oil. Out of 1.6 million engineers, petroleum engineers held 21,900 jobs. Jobs are expected to grow very well throughout the next decade. The petroleum engineers holding bachelors degree earned on average $108, 020. The median of petroleum engineers earned $108,020. To get a license for chemical engineering you have to have a degree from an accredited engineering program, four years of relevant work experience, and a completion of a state exam. A professional society for engineering is the Society of Petroleum Engineers (SPE). The top three schools for petroleum engineering are the University of Texas, Stanford University, and Texas A&M.http://www.bls.gov/oco/ocos027.htm
