About the role

Key responsibilities & impact

Build and calibrate hydraulic fracture growth models 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 interactions using fracture mechanics principles
Account for fracturing-fluid rheology, fracture geometry, and proppant transport in models
Incorporate completion design parameters into fracture growth models and iterate as new data arrives
Translate calibrated fracture models into simulation-ready fracture network representations
Quantify uncertainty in fracture geometry and connectivity and communicate impacts on well and pad performance
Build and maintain full-field and sector-scale reservoir simulation models for fractured EGS reservoirs
History-match production and injection rates, bottom-hole pressures, and thermal response against field data
Iterate permeability, fracture conductivity, compartmentalization, and injector-producer connectivity parameters
Diagnose model, data, and operational sources of history-match mismatch
Use history-matched models to inform forecasts, well spacing, and injection/production strategy
Design pressure transient, interference, tracer, DFIT, PLT/DTS/DAS diagnostic and surveillance programs
Identify data gaps and prioritize acquisition programs within cost and schedule constraints
Define minimum viable data requirements per well and pad
Extend calibrated models to new prospects and support crossflow test program design
Build repeatable workflows using automation and scripting
Collaborate with Completions, D&C, Reservoir, Resource, Exploration, and Data Science teams
Document modeling methodologies and calibration standards
Provide data-driven recommendations and contribute to transparency, consistency, and continuous improvement

Requirements

What you’ll need

B.S. in Engineering (Petroleum, Mechanical, Chemical, or related discipline)
5+ years of experience in reservoir engineering, reservoir simulation, or hydraulic fracture modeling; advanced degree may be considered in lieu of experience
Hands-on experience with reservoir and/or fracture simulation software (e.g., ResFrac, CMG, Eclipse, or comparable)
Experience history matching production, pressure, and/or fracture growth data against simulation models
Strong understanding of fluid flow in fractured/porous media and hydraulic fracture mechanics
Experience interpreting pressure transient and completion diagnostic data (DFITs, PLT/DTS/DAS, tracer, microseismic)
Strong analytical and programming/scripting skills (e.g., Python) to support model calibration and workflow automation
Strong analytical, synthesis, and communication skills, including the ability to explain model uncertainty clearly
Preferred: experience in geothermal reservoir engineering, enhanced geothermal systems (EGS), or unconventional resource development
Preferred: direct experience with ResFrac or other coupled geomechanics/fracture-reservoir simulators
Preferred: working knowledge of fracture mechanics and in-situ stress state, including natural fracture (NF) interactions
Preferred: familiarity with fracturing-fluid rheology and its impact on fracture geometry, height growth, and proppant placement
Preferred: experience designing diagnostic testing programs to support model calibration, including forward-looking crossflow test design
Preferred: experience integrating DAS/DTS, tracer, microseismic, and PLT datasets into a calibration workflow
Preferred: experience with assisted/automated history matching techniques, including ensemble methods and machine learning-assisted calibration
Preferred: ability to translate detailed technical analysis into executive-level summaries
