Kiewit Vancancies: and you are to forward your Cv / resume to this email: email@example.com Working as a mechanical engineer in oil and gas is not for someone who’s afraid of taking risks. An important job duty is to advise corporate leaders about the best location for an oil well. Often referred to as speculative oil drilling, choosing a site can be challenging. Since oil sources can be as deep as 20,000 feet, mechanical engineers test rocks and collect data to determine the best possible location. Once a site has been selected, a mechanical engineer oversees the assembly of the oil drill, ensures the operation runs smoothly and makes recommendations about the amount of oil that can be extracted. Once oil drilling is finished, a mechanical engineer supervises the deconstruction of the equipment and makes sure that the site is free of residual waste. Long hours, mostly in the field, are common for a mechanical engineer in oil and gas.
