Requisition Id 14269 

Overview: 

Oak Ridge National Laboratory is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security.

We are seeking a Postdoctoral Research Associate who will support the Manufacturing Energy Efficiency Research & Analysis (MEERA) Group in the Manufacturing Science Division (MSD), Energy Science and Technology Directorate (ESTD) at Oak Ridge National Laboratory (ORNL) to work in the areas of life cycle energy impacts analysis, technoeconomic analysis, and industrial energy efficiency analysis research under the Strategic Analysis and Industrial Energy Efficiency Programs.

The MEERA Group conducts techno-economic, value chain, trade, patent, and global analyses relevant to advanced energy and manufacturing technologies. MEERA is currently supporting a multi-laboratory DOE Geothermal Technologies Office (GTO) project to develop an independent, objective, and publicly available geothermal well life cycle assessment analysis. This project will conduct research into alternative geothermal well designs that can improve the life cycle value of geothermal wells, reduce costs, improve productivity, and mitigate risks. The project builds upon previous MEERA work focusing on casing and cementing activities that identified the cost of casing, cement and cement additives, and annulus area as key variables in reducing total drilling cost. This project expands the analysis to other aspects of geothermal well development including well completion, production, and abandonment phases.

Major Duties/Responsibilities:

• Conduct techno-economic, value chain, and global manufacturing competitiveness analysis in the area of geothermal well development.
• Analyze supply chain, material flows, and development costs throughout the lifecycle of a geothermal well to identify opportunities to reduce materials, time, and environmental impact of geothermal wells.
• Help support other MEERA Group industrial technical deployment (Better Plants) and Energy System Software Tools development projects.
• Help support the development of new resources, trainings, and tools to support companies participating in the DOE’s Better Plants program.
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Basic Qualifications:

• A PhD in mechanical engineering, industrial engineering, environmental engineering, chemical engineering, geothermal engineering or a related field completed within the last 5 years.
• Quantitative and analytical research background which can be applied to conduct research analysis on geothermal well development and other advanced energy technologies that could achieve transformative gains in energy efficiency.
• Ability to develop optimization and life cycle models analyzing advanced energy technologies.
• Strong analytical capabilities with experience in life cycle energy and cost assessments for technology assessments.

Preferred Qualifications:

• An educational background in sustainable manufacturing technologies with an emphasis on life cycle research.

• Experience in manufacturing process or energy systems modeling.
• Proficiency in the use of industry standard modeling and simulation tools, such as spreadsheet-based process cost modeling, input/output modeling, or commercially available life cycle analysis tools such as SimaPro and openLCA.
• Excellent written and oral communication skills.
• Motivated self-starter with the ability to work independently and participate creatively in collaborative teams.
• Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs

Open Position May 16, 2025

Description

The Senior Seismologist will lead the design, implementation, and processing of critical borehole and surface seismic monitoring campaigns to support Fervo Energy’s Enhanced Geothermal operations. This role is central to executing Fervo’s induced seismicity monitoring and mitigation plans, leveraging extensive datasets from fiber optic sensing, seismometers, and dense nodal arrays. A key responsibility is the development of advanced workflows for real-time microseismic processing using fiber-optic Distributed Acoustic Sensing (DAS). This includes estimating event magnitudes, focal mechanisms, and stress drops from DAS data, and integrating these insights into building rupture models and assess seismicity risk. The Seismologist will also play a leadership role in securing and managing research grants as Principal Investigator, fostering collaboration with national laboratories and academic institutions. While Fervo already has systems in place for real-time earthquake cataloging, this role encourages innovation in catalog-building techniques, especially those leveraging DAS and geophone data. The ideal candidate will develop algorithms that enhance real-time seismic hazard assessment and inform operational response protocols. Open to candidates across experience levels who meet the qualifications, this position will be an integral part of a multidisciplinary team of geophysicists, fiber-optic specialists, reservoir engineers, and computational scientists. The Seismologist will report to the Manager of Data Acquisition and Advanced Analytics.

Responsibilities

• Process and interpret microseismic and fiber optic strain/strain rate data to inform geologic models and evaluate reservoir performance.
• Analyzing induced seismicity to assess seismic hazard, support risk mitigation strategies, and optimize stimulation and completion efficiency.
• Extract earthquake source parameters—including magnitude, focal mechanism, and stress drop—from DAS, geophones, and seismometers; develop and apply rupture models to characterize fault behavior.
• Design and implement algorithms for real-time seismic hazard assessment using physics-based modeling, statistical analysis, and machine learning approaches.

Required Qualifications

• Master’s or Ph.D. in Geophysics, Seismology, Applied mathematics or a related field.
• Strong proficiency in earthquake source analysis, including moment tensor inversion, stress drop estimation, and stress inversion. Experience with DAS-based earthquake source characterization is a plus but not required.
• Demonstrated ability to develop analytical and numerical models for interpreting strain and strain rate from fiber-optic DAS data during hydraulic stimulation and geothermal production.
• Experience integrating seismic observations with Thermo-Hydro-Mechanical-Chemical (THMC) models to evaluate seismic and aseismic slip processes.
• Proficiency in Python for seismic data processing, including scripting, tool development, and algorithm implementation; familiarity with Linux-based computing environments.

Preferred Qualifications

• Experience in High Performance Computing.
• Background in solving inverse problems related to seismological data.
• Experience in applying machine learning techniques to seismological problems.

Location
Fervo Energy is headquartered in Houston, TX with satellite offices in the Bay Area, CA, Golden, CO and Reno, NV. This position will be eligible for some hybrid work flexibility, but regular in-office presence at the Houston OR Golden, CO office will be required. Some travel is required for this position. 

Compensation and Benefits
Fervo provides a comprehensive suite of benefits including medical, dental, vision, life, short-term and long-term disability, flexible paid time off, and paid parental leave. Additionally, Fervo offers an incentive stock options program, a bonus incentive program, and a 401(k) plan with an employer match.

The roles will provide a mix of field geology, well design and construction, technology development, and interactions with customers and subcontractors.

With funding from the NSF, DOE, USDA, State of Minnesota, and climate investors, Darcy is pioneering a new groundwater-based, geothermal approach to sustainable heating and cooling for commercial and multi-family residential buildings. We’re working closely with our industry partners to pioneer new and exciting, integrated ground loop-HVAC designs to help our customers meet increasingly aggressive carbon emissions goals and energy efficiency requirements while lowering costs. Our approach incorporates elements of water well and geothermal technology, resulting in a novel way to put groundwater to work.

The Staff/Senior Geologist positions offer candidates the chance to be part of an innovative company impacting greenhouse gas emissions in a collaborative work environment with opportunities for professional growth and development.
