Technology Center Scientist II

About the Role

We are seeking an experienced Laboratory Scientist to support advanced rock characterization and core analysis activities within our Weatherford Laboratory. This role involves operating a Scanning Electron Microscope (SEM) system and supporting broader conventional and unconventional core analysis workflows. The ideal candidate will work closely with geologists, petrophysicists, and engineers to generate high-quality analytical data supporting reservoir characterization, completion optimization, and field development programs across EOG's asset portfolio.

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

Responsibilities

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

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, and Special Core Analysis Testing.

Requirements

• Bachelor's or Master's Degree, preferred in Geology or related Engineering 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 core analysis 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.

Desired Attributes

• Strong hands-on laboratory mindset; willing and 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.
