About This Career
You may rock at this career. You bring deep knowledge about the rocks and underground conditions that influence how a well is drilled and how it will produce. The job of the Wellsite Geologist is to use data to guide drillers through hundreds of metres of earth and rock and to help obtain the highest production levels possible from a reservoir.
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.
In this occupation, activities may include:
- Performing reservoir analysis for consolidation, grain size, roundness, porosity and cementation
- Informing and advising on measurements, program requirements and revisions while drilling and mud logging
- Selecting the casing point based on data such as isopachs, changes in drilling parameters and samples
- Communicating with the Rig Supervisor on geological risks and casing point tallies
- Advising the logging company of program revisions and timing
- 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.
- Workplace Hazardous Materials Information System (WHMIS)
- Standard and emergency first aid

- Having a Professional Geologist designation, while not strictly required in every jurisdiction, is preferred and/or required by many organizations. Licenses are issued by provincial jurisdictions and may provide interprovincial mobility.
- Unlicensed Geologists may be required to work under the supervision of a licensed Geologist.
