Formation evaluation
We rely on expert knowledge to interpret specialized data. The Formation Evaluation group maintains a fundamental understanding of wellbore logging measurement technologies and measurement of reservoir properties from rock samples obtained from the wellbore. They use methodologies that provide accurate interpretation of reservoir and fluid properties and work with the subsurface team to evaluate results. Beyond data interpretation, specialists lead the planning for wellbore data acquisition, and steward the acquisition process with an eye on quality controls all the way through post-processing. Specialists may have a geoscience, engineering or other technical background.
Example roles: (Early and Advanced) Formation Evaluation
Generalist
Our biggest challenges require go-to experts. Generalists develop and hone a broad range of fundamental geological and geophysical skills to create reliable, integrated interpretations that support our core business. Technical knowledge such as reservoir characterization, drill well planning and reservoir surveillance, drives this group, along with a commitment to developing ideas and skills to solve problems across exploration, development, production and research.
Example roles: (Early and Advanced) Generalist
Geophysical Applications
Our industry-leading business decisions are informed by deep proficiency. The Geophysical Applications group delivers integrated geophysical technologies, workflows and application solutions across our upstream businesses. With specialized expertise, this group applies advanced geophysical tools and processes for making subsurface predictions.
Example roles: (Early and Advanced) Geophysical Applications
Geophysical Operations
We reach business goals without losing sight of safety, efficiency, and the environment. The Geophysical Operations group maintains the capabilities for the design, planning and execution of seismic data and shallow seabed acquisition programs across four sub-disciplines: Data Analysis/Survey Design, Geophysical Field Supervision, Operations Integrity/SSH&E and Geophysical Operations Research. Additionally, specialists in this group work with a multi-functional team to develop data acquisition programs.
Example roles: (Early & Advanced) Geophysical Operations, Advanced Data Analysis/Survey Design, Field Supervision, Research and Integrity/SSH&E
Geophysical Processing

The Geophysical Operations group maintains the capabilities for the design, planning and execution of seismic data and shallow seabed acquisition programs across four sub-disciplines: Data Analysis/Survey Design, Geophysical Field Supervision, Operations Integrity/SSH&E and Geophysical Operations Research. Additionally, specialists in this group work with a multi-functional team to develop data acquisition programs.
Example roles: (Early & Advanced Geophysical Processing) Research Focused, Advanced External Management and Data processing
Hydrocarbon Systems and Assessments
Our business decisions are informed by expert analysis. The Hydrocarbon Systems and Assessments group performs volumetric uncertainty analysis, value of information assessments, multiple scenario analysis, risking sessions and Prospect/Play evaluations. This group is primarily comprised of petroleum geochemists, basin modelers, reservoir quality experts and assessors, but also maintains specialized skills in fluid inclusion analysis, noble gases, genetic basin analysis and more.
Example roles: (Early & Advanced) Hydrocarbon Systems, (Advanced Capability) Assessment, Petroleum Geochemistry & Reservoir Quality
Geoscience Technicians
Data integrity is essential in every aspect of our business. Our geoscience technicians oversee data and provide technical products to support our geoscientists.
Example roles: (Early & Advanced) Geoscience Technicians and Laboratory Technicians
Operations geology
Safety and the environment stay at the forefront as our Operations Geology group oversees the planning and surveillance of ExxonMobil’s drillwells. This group also develops drilling and evaluation programs that allow the drillwell to reach, evaluate and complete geologic objectives. The three sub-disciplines of Operations Geology are Site Investigation, Integrated Pore Pressure Prediction and Well Planning & Surveillance.
Example roles: (Early) Operations Geology , (Advanced) Pore Pressure Prediction & Surveillance, Site investigation and Well Planning & Surveillance
Reservoir Modeling
Predict the outcomes of today while supporting development planning for tomorrow. The Reservoir Modeling group integrates structural and stratigraphic descriptions, seismic interpretation, reservoir quality data, reservoir performance data and geologic concepts to characterize a reservoir system, its constituent rock property types and their architecture. Members of this group have a deep knowledge of the fundamentals of geoscience and reservoir engineering, and work with many roles across geoscience and engineering.
Example roles: (Early & Advanced) Reservoir Modeling
Stratigraphy
High-quality technical work is the basis of many of our biggest business decisions. The Stratigraphy group provides stratigraphic analysis, including play element prediction and reservoir characterization.
Example roles: (Early & Advanced) Carbonate / Siliciclastic Stratigrapher and (Advanced) Biostratigrapher
Structure
Our business decisions are powered by technical skills. The Structure group conducts the highest quality work in rock deformation components by evaluating the folding and fracturing of rocks. This group also stewards the major components of trap-seal risking in exploration settings. Practitioners construct structural frameworks integrating core, wireline log and seismic data.
Example roles: (Early & Advanced) Structure Analyst, (Advanced) Fracture Analysis, Geomechanics and Integrated Trap Analyst
