Job Description
Seeking an experienced Laboratory Technician to support advanced rock characterization and core analysis activities within our Weatherford Laboratory. Duties include operating a Scanning Electron Microscope (SEM) system while also supporting broader conventional and unconventional core analysis workflows.
The ideal candidate will have strong laboratory experience, mechanical aptitude, analytical discipline, and hands-on familiarity with geological sample handling and core analysis procedures. This position will work closely with geologists, petrophysicists, 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 technician-focused role requiring both instrument operation and practical laboratory execution in a fast-paced applied research and operations environment.
Primary Responsibilities
SEM & Imaging Operations
- Operate and maintain Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS) systems.
- Acquire high-quality secondary electron (SE) and backscatter 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.
Core Analysis Support
- 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
- Maintain accurate sample tracking, chain-of-custody, and QA/QC documentation.
Laboratory Operations
- 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.
Desired Attributes
- 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.
Work Environment
- Laboratory-based position requiring standing, lifting, and handling of rock samples and laboratory equipment.
- Frequent microscope and computer workstation use.
- Occasional movement of core boxes and analytical equipment.
- Laboratory safety compliance required at all times.
JOB REQUIREMENTS
Associate’s degree or Bachelor’s degree, preferred in:
- Geology, Petroleum Technology, Materials Science, Chemistry, Engineering Technology, or related technical field
- Minimum 5-10+ years of laboratory experience in one or more of the following: Core analysis, Geological laboratory operations, SEM or microscopy, Petrophysical laboratory testing
- Strong mechanical aptitude and troubleshooting ability.
- Experience handling and preparing geological core or rock samples.
- Strong organizational skills and attention to detail.
- Ability to safely operate laboratory equipment and follow established procedures.
- Proficiency with standard computer software and digital data management.
Preferred Qualifications
- Direct experience operating SEM/EDS instrumentation.
- Experience in oil and gas core analysis laboratories.
- Familiarity with unconventional shale reservoir characterization.
- Knowledge of pore system analysis, mineralogy, organic matter imaging, or microfracture characterization.
- Experience with laboratory QA/QC systems and analytical documentation.
- Experience with image analysis or geological imaging software.
- Familiarity with core handling procedures.
- Understanding of routine core analysis (RCAL) and/or special core analysis (SCAL) methodologies.
