• Acquire high-quality secondary electron (SE) and back scatter electron (BSE) images of geological materials, including elemental analysis and mineral identification using EDS workflows.
• Assist with development and optimization of SEM imaging procedures for unconventional reservoir characterization.
• Prepare geological samples including core plugs, slabbed core, cuttings, polished mounts and Ion-milled samples including conductive coating and maintaining sample prep equipment
• Organize and archive analytical images and laboratory data.

• Support routine and specialized core analysis workflows on conventional and unconventional reservoir samples.
• Assist with laboratory testing including porosity and permeability measurements, fluid saturation analysis, extractions & drying, rock sample preparation, Special Core Analysis Testing
• Assist with laboratory measurement of reservoir rock properties including wettability, capillary pressure, relative permeability, fluid saturation, and fluid-rock interaction experiments.
• Support preparation, handling, and preservation of reservoir fluids, produced water, brines, and chemical solutions for laboratory testing.
• Maintain accurate sample tracking, chain-of-custody, and QA/QC documentation.

• Coordinate analytical priorities and sample workflows with technical staff and project teams.
• Assist in generating presentation-quality figures, photomicrographs, and laboratory summaries.
• Support continuous improvement of laboratory workflows, efficiency, and analytical consistency.
• Work effectively across multiple simultaneous projects and shifting operational priorities.
• Support laboratory testing programs associated with reservoir fluids characterization, fluid and rock properties, and fluid-rock interaction research initiatives.
• Assist with calibration, maintenance, troubleshooting, and operation of laboratory instruments used for rock and fluid property measurements.

• Strong hands-on laboratory mindset. Willing / able to be on your feet most of the day.
• Detail-oriented and highly organized.
• Self-motivated with strong initiative.
• Ability to learn and adapt to new analytical technologies.
• Team-oriented with strong communication skills.
• Capable of balancing analytical precision with operational efficiency.
