Assistant Wellsite Geologist Jobs (NOW HIRING)

Description

Fervo is working to build the most cost-effective, repeatable geothermal power plants in the world. Delivering on this mission requires deep subsurface understanding, disciplined execution in the field, and continuous learning across the full project lifecycle. Joining Fervo's Subsurface organization means operating at the intersection of geology, engineering, and real-world execution where data-driven decisions directly shape development outcomes.

We are seeking a Geologist who is excited by Fervo's mission and motivated to support the design, planning, and execution of large-scale geothermal developments. This role is ideal for a geologist with operational experience, strong technical fundamentals, and a desire to grow into increasing technical and execution responsibility within a highly collaborative environment.

The Geologist supports wellfield design, planning, and execution activities across Fervo's geothermal development portfolio. This role contributes to subsurface characterization, geologic modeling, and operational decision-making during drilling, completion, and testing activities.

Working closely with senior geologists, reservoir engineers, geophysicists, and drilling and completions teams, the Geologist integrates geological, geochemical, and geophysical data to build and maintain conceptual and three-dimensional geologic models. Success in this role requires curiosity, strong communication skills, comfort working in data-rich and execution-heavy environments, and a willingness to engage directly with field operations.

Requirements

Responsibilities

Well Planning, Drilling & Operations Support

• Support planning and execution of geothermal drilling and completion campaigns, including providing real-time geological input during active operations
• Develop and QC development plans, well paths, and geologic prognoses for assets under development
• Plan and supervise mudlogging, logging, sampling, and general wellsite geology activities
• Support preparation and execution of short- and long-term flow tests for resource confirmation and early production testing

Geologic Modeling & Subsurface Characterization

• Integrate geological, geochemical, and geophysical datasets to support development and maintenance of conceptual and 3D geologic models
• Assist in development of petrophysical and geomechanical models to characterize reservoirs, fracture systems, and subsurface stress conditions
• Perform offset well analysis to support geologic prognoses, well planning, and risk assessment
• Support interpretation of logs, cores, cuttings, and seismic data to refine subsurface understanding

Cross-Functional Collaboration & Documentation

• Work closely with reservoir engineering, geophysics, drilling, completions, production, and land teams to support wellfield planning and development
• Contribute to Statements of Requirements, Basis of Design documents, and After-Action Reviews
• Prepare clear technical summaries and presentations for internal stakeholders and cross-functional reviews
• Support asset management activities, resource assessment, and technical input to project evaluations

Data, Vendors & Continuous Learning

• Support management of subsurface data acquisition vendors and service providers related to logging, sampling, and testing
• Assist with data quality control, integration, and archiving across subsurface datasets
• Capture operational learnings from drilling and testing activities and apply them to improve workflows and geologic interpretations
• Travel periodically to field sites (primarily western U.S.); travel may increase during active drilling campaigns (up to ~20-30%)

Qualifications

Required

• Bachelor's degree in geology, geophysics, or a related discipline
• 3+ years of professional experience in geothermal and/or oil & gas subsurface roles
• Working knowledge of geologic interpretation and subsurface data integration using industry-standard software (Petrel experience strongly preferred)
• Experience supporting drilling, completions, or wellsite operations in a development or production context
• Ability to interpret basic subsurface data sets, including well logs seismic data
• Strong analytical skills and the ability to communicate technical findings clearly to cross-functional teams
• Willingness and ability to travel to field locations as required during drilling and testing operations

Preferred

• Master's degree in geology, geophysics, or a related discipline
• Operations geology experience during active drilling campaigns
• Experience with petrophysical log interpretation and image log analysis
• Exposure to geomechanics, fracture characterization, or subsurface stress analysis
• Background in structural geology or geothermal reservoir characterization
• Experience working on horizontal wells or multi-well development projects
• Familiarity with geologic resource assessment, reserve estimation, or project economics support
• Experience with geochemical data (e.g., produced water or groundwater analysis)
• Interest or experience in data analytics, geostatistics, or uncertainty analysis
