About This Career
Wellsite Geologists supervise every stage of the drilling process to extract oil and natural gas from deep underground. They study and analyze rocks from oil and gas wells in order to direct the drilling, and identify the rock formation into which they are drilling. They use specialized tests such as petrographic analysis, rock-cutting data, wireline data, core samples and other measures to accomplish this work. Wellsite Geologists document results from drilling activities, analyze and evaluate this information in order to inform the Development/Reservoir Geologist about the status of drilling activities. The Wellsite Geologist is responsible for executing a drilling plan, provided by the Development/Reservoir Geologist, and making real time decisions.
Education: A post-secondary degree in geology is typically required. However, a post-secondary diploma from a technical institute or a graduate degree in chemistry, geochemistry, physics or geophysics may be another route into this occupation.
Employment: This occupation is found in onshore and offshore environments and is typically employed in exploration and production, oil sands and oil and gas services sectors of the oil and gas industry.
