In the petroleum industry, gas engineers, also known as petroleum engineers, work out in the field to help identify new gas well locations and design the most efficient way to extract gas from underground. A gas engineer often spends time on geographic surveys, assessing the stability of the land and whether or not it is appropriate for drilling. The job requires involvement in every aspect of the process, from ordering pumps and equipment to installing the pipes and extraction tools. When not in the field, duties include assessing rocks, performing site trials, and designing ways to improve the efficiency of drilling and pipeline technology.
