Job Summary
Role Overview
Title: Senior Geothermal Reservoir Engineer
Hours: Full-Time Salaried
Location: Salt Lake City UT Hybrid (3 days in office 2 days can be remote)
Benefits Eligible: Yes
Manager: Head of Exploration or Head of Reservoir R&D (depending on applicants skillset)
Why we exist
Geothermal energy is the most abundant renewable energy source in the world. There is 2300 times more energy in geothermal heat in the ground than in oil gas coal and methane combined. However historically its been hard to find and expensive to develop. At Zanskar were building technology to find and develop new geothermal resources in order to make geothermal a cheap and vital contributor to a carbon-free electrical grid.
At Zanskar we combine deep subsurface expertise with modern data and modeling to improve geothermal discovery and development outcomes. We conduct well tests and build reservoir models to make better calls on well targeting and field optimization strategy.
Who you are
The Senior Geothermal Reservoir Engineer will play a critical role in understanding and forecasting geothermal reservoir performance and translating that understanding into field development decisions. A successful candidate will:
- Lead - own reservoir engineering workstreams end-to-end: test planning execution support interpretation model updates and recommendations.
- Model - move fluently between well test interpretation and numerical simulation and reconcile mismatches between model predictions and field behavior.
- Collaborate - partner closely with geoscience drilling facilities and operations teams to drive alignment and decision quality.
- Teach - raise the technical bar through strong documentation clear communication and mentorship across disciplines.
What youll do
Well test design execution support and interpretation
- Plan and oversee well tests and surveillance programs (production tests injection tests pressure transient tests interference tests falloff/step-rate tests spinner/PTS campaigns and tracer tests as appropriate).
- Provide real-time support during tests and interpret results post-test (e.g. permeability-thickness skin boundaries connectivity injectivity/productivity and reservoir pressure trends).
- Build repeatable analysis workflows templates and QC checks so results are trustworthy and comparable across wells and campaigns.
History matching and integrated reservoir/wellbore modeling
- Build calibrate and maintain reservoir models that match observed field history (rates pressures temperatures/enthalpy injectivity/productivity and tracer/connectivity signals).
- Perform sensitivity and uncertainty analysis; communicate what is known vs. uncertain and what data would most reduce uncertainty.
Forecasting development planning and optimization
- Generate production and injectivity forecasts under multiple operational and development scenarios (including uncertainty ranges).
- Evaluate reservoir management strategies (injection allocation make-up well timing pump strategies and remediation options as relevant).
- Translate model outputs into decision-ready recommendations (generation impacts operational tradeoffs and key risks).
Data tooling and cross-functional communication
- Maintain high-quality operating datasets and ensure completeness and provenance across test data production/injection data and well logs.
- Build lightweight analytics (Python/SQL) to automate recurring analyses and monitoring dashboards.
- Present findings via concise memos and reviews; be the owner of the reservoir narrative that leaders and operators can rely on.
What were looking for
- B.S. (or higher) in Reservoir Engineering Petroleum Engineering Mechanical Engineering Geoscience or a related field.
- 4 years of reservoir engineering experience in geothermal and/or analogous subsurface industries (oil & gas hydrogeology CCS) with demonstrated ownership of well tests and reservoir modeling work.
Proven excellence in several of the following technical skills:
- Well testing and surveillance: design and interpretation of PTA (build-up falloff/step-rate) interference/connectivity tests injectivity/productivity and tracer-based diagnostics; strong data QC.
- Numerical simulation: develop and update geothermal reservoir models with wellbore models; calibrate against field data and integrate geologic constraints into conceptual and numerical models.
- History matching: ability to adjust parameters systematically understand non-uniqueness and communicate uncertainty and model limitations.
- Forecasting: scenario-based production and injectivity forecasts tied to operational constraints; translate results into actionable field recommendations.
- Cross-functional communication: write clear technical memos present tradeoffs and collaborate effectively with operations drilling and facilities teams.
- Nice-to-haves: reservoir-surface network integration; probabilistic history matching/optimization workflows; fluency in Python and SQL.
Location and Benefits
- The position is based out of our headquarters in Salt Lake City Utah and is a hybrid position with periodic travel (15-30%) to operating geothermal assets.
Benefits include:
- Paid holidays
- 18 days PTO PTO accrual increase based on tenure
- Medical dental and vision coverage
- 401k Stock options
- Paid Parental Leave
- Growth opportunities at a company with a direct impact in displacing carbon emissions
