Technology Center Scientist II

Seeking an experienced Laboratory Scientist to support advanced rock characterization and core analysis activities within our Weatherford Laboratory. Duties include operating a Scanning Electron Microscope (SEM) system and supporting broader conventional and unconventional core analysis workflows.

The ideal candidate will have strong laboratory experience, analytical discipline, and hands-on familiarity with geological sample handling and core analysis procedures. This position will work closely with geologists, petrophysicists, and engineers alongside laboratory staff to generate high-quality analytical data supporting reservoir characterization, completion optimization, and field development programs across EOG's asset portfolio.

This is a role requires both instrument operation and practical laboratory execution in a fast-paced applied research and operations environment.

• Coordinate analytical priorities and sample workflows with division petrophysicists and geologists to address specific technical goals of the division in a proprietary work environment
• Technology development & structure with core analytical techniques
• Support in coordinating vendor lab work supplementary to in-house experiments
• 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.

• Operate and maintain Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS) systems.
• 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
