Position Type:

Full Time, Regular

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.
The role will also support laboratory programs focused on Chemical Enhanced Oil Recovery (EOR), reservoir fluids characterization, fluid-rock interaction studies, and experimental testing of surfactant, polymer, and other chemical treatment technologies.
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
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.

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.
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.

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.
Demonstrates strong laboratory safety awareness and familiarity with chemical handling and experimental testing procedures.

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 Engineering, Chemical Engineering, 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, Reservoir fluids analysis, Chemical EOR laboratory testing, Rock-fluid interaction studies, Special Core Analysis (SCAL), Oilfield chemistry laboratory operations
Strong mechanical aptitude and troubleshooting ability.
Experience handling and preparing geological core or rock samples.
Experience conducting laboratory measurements of fluid and rock properties.
Experience working with reservoir fluids, brines, solvents, surfactants, polymers, or other chemical systems used in oilfield applications is desirable.
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.
Experience supporting rock and fluid properties, conformance, or fluid-rock interaction projects.
Experience measuring fluid properties such as viscosity, density, rheology, interfacial tension (IFT), emulsion characteristics, and phase behavior.
Experience conducting wettability, relative permeability, capillary pressure, adsorption, chemical retention, or coreflood testing.
Familiarity with surfactant, polymer, alkali-surfactant-polymer (ASP), or other EOR chemical systems.
Experience preparing and handling laboratory chemical solutions and conducting tests under established QA/QC protocols.

Position will be filled at a level commensurate with experience.
