Job Description
Joining Fervo as a Reservoir Engineer focused on reservoir modeling and history matching means owning the calibration of our subsurface models against real field performance — both the stimulation fracture growth created during completions and the production and pressure response of the reservoir over time.
Key Responsibilities
- Stimulation & Fracture Growth History Matching
- Build and calibrate hydraulic fracture growth models (e.g., ResFrac or comparable geomechanical/fracture simulators) against observed stimulation data.
- History-match fracture height, length, and complexity using treatment pressure, microseismic, DAS/DTS, and tracer data.
- Characterize in-situ stress state and natural fracture (NF) interactions using fracture mechanics principles to guide fracture growth and stress-shadow modeling.
- Account for fracturing-fluid rheology in fracture models, including its influence on fracture width, height growth, and proppant transport.
- Incorporate completion design parameters (stage spacing, cluster design, pump schedule, fluid/proppant systems) into fracture growth models and iterate as new stimulation data arrives.
- Translate calibrated fracture models into simulation-ready fracture network representations for downstream reservoir modeling.
- Quantify uncertainty in fracture geometry and connectivity and communicate its impact on well and pad performance predictions.
- Reservoir Production & Pressure History Matching
- Build and maintain reservoir simulation models (full-field and sector-scale) representing fractured EGS reservoirs.
- History-match production and injection rates, bottom-hole pressures, and thermal/temperature response against field data.
- Iterate reservoir model parameters (permeability, fracture conductivity, compartmentalization, injector-producer connectivity) to improve match quality across wells and pads.
- Diagnose root causes of history-match mismatch and distinguish model, data, and operational sources of error.
- Use history-matched models to inform production forecasts, well spacing, and injection/production strategy.
- Testing & Data Program Development
- Design diagnostic and surveillance testing programs — pressure transient tests, interference tests, tracer tests, DFITs, PLT/DTS/DAS — specifically to improve history-matching accuracy.
- Identify the data gaps most limiting model calibration and prioritize acquisition programs to close them.
- Define minimum viable data requirements per well and pad to support robust history matching within cost and schedule constraints.
- Continuously evaluate testing protocols against realized model performance and refine the testing program based on lessons learned.
- Extend calibrated models beyond history matching to new prospects, forecasting anticipated crossflow behavior and helping design corresponding crossflow test programs; scope and cadence for this forward-looking work will be defined in coordination with Resource and Exploration teams.
- Build repeatable workflows (including automation/scripting) to speed up history-matching iteration and testing feedback loops.
- Cross-Functional Collaboration
- Partner with Completions and D&C to align stimulation design changes with fracture model predictions and observed outcomes.
- Partner with Reservoir and Resource teams to ensure production, injection, and pressure data flows support ongoing model calibration.
- Document modeling methodologies and calibration standards to promote consistency across projects.
- Team and Culture
- Operate with technical independence and objectivity while maintaining strong collaborative relationships with Completions, D&C, and asset teams.
- Provide constructive challenge and thoughtful recommendations grounded in data and engineering principles.
- Balance rigor with pragmatism in a fast-paced, cross-functional environment.
- Contribute to a culture of transparency, consistency, and continuous improvement across the portfolio.
- Be responsive and reliable in remote settings, maintaining momentum without requiring constant oversight.
- Adapt quickly to shifting priorities, new data, and evolving model scopes.
Requirements
- Experience in geothermal reservoir engineering, enhanced geothermal systems (EGS), or unconventional resource development.
- Direct experience with ResFrac or other coupled geomechanics/fracture-reservoir simulators.
- Working knowledge of fracture mechanics and in-situ stress state, including natural fracture (NF) interactions, to guide fracture growth and stress-shadow modeling.
- Familiarity with fracturing-fluid rheology and its impact on fracture geometry, height growth, and proppant placement.
- Experience designing diagnostic testing programs specifically to support model calibration, including forward-looking crossflow test design for new prospects.
- Experience integrating multiple diagnostic datasets (DAS/DTS, tracer, microseismic, PLT) into a single calibration workflow.
- Experience with assisted/automated history matching techniques (e.g., ensemble methods, machine learning-assisted calibration).
- Ability to translate detailed technical analysis into executive-level summaries.
