Get Access To All JobsTitle: 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 applicant’s skillset)
Why we exist
Geothermal energy is the most abundant renewable energy source in the world. There is 2,300 times more energy in geothermal heat in the ground than in oil, gas, coal, and methane combined. However, historically it’s been hard to find and expensive to develop. At Zanskar, we’re 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 you’ll 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 we’re 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

Get Access To All JobsTips for Finding Visa Sponsorship as a Reservoir Engineer
Verify your degree meets specialty occupation requirements
A bachelor's degree in petroleum engineering, geosciences, or a closely related field is what ties your credentials to the specialty occupation standard. If your degree is in a broader discipline like mechanical or chemical engineering, gather documentation showing your coursework directly supports reservoir analysis and simulation.
Target employers with active LCA filing history
Oil majors, independents, and oilfield services companies file LCAs for reservoir engineering roles consistently. Use Migrate Mate to identify employers with verified sponsorship history for petroleum and reservoir engineering positions, so you're applying where the path already exists.
Distinguish upstream from downstream when researching sponsors
Sponsorship activity in oil and gas is concentrated in upstream exploration and production. Refining and midstream operations hire fewer reservoir engineers and sponsor at lower rates. Narrowing your search to E&P companies improves your odds of landing a role with an active filing program.
Get your reservoir simulation software credentials documented
Employers filing H-1B petitions for reservoir engineers often need to demonstrate the role requires specialized knowledge. Certifications or project documentation in Eclipse, Petrel, or CMG can strengthen the specialty occupation argument in your petition and reduce the likelihood of a Request for Evidence.
Understand how the LCA prevailing wage affects your offer
Your employer must certify your offered wage meets or exceeds the prevailing wage for your location. Use the OFLC Wage Search to look up the wage level for petroleum engineers in your target city before negotiating, so you're not accepting an offer that creates compliance problems at filing.
Start the PERM conversation before you need it
Reservoir engineering roles are well-suited for EB-2 or EB-3 green card sponsorship through PERM. Raise the topic during the offer stage, not years later. DOL's PERM labor certification process takes time, and starting early gives your priority date the best chance to stay ahead of backlogs.
Frequently Asked Questions
Does a reservoir engineer role qualify as a specialty occupation for the H-1B?
Yes. Reservoir engineering requires at least a bachelor's degree in petroleum engineering, geosciences, or a closely related discipline, which satisfies USCIS's specialty occupation definition. USCIS reviews the relationship between the degree and the actual job duties, so employers should document that the role genuinely requires that specific educational background rather than a general engineering degree.
Which visa types are realistic for reservoir engineers seeking U.S. sponsorship?
The H-1B is the most common path, covering specialty occupation roles and granting up to three years initially, extendable to six. Australian nationals can pursue the E-3 visa, which has no lottery and renews every two years. TN visa status is not available for reservoir engineers because petroleum engineering is not on the USMCA profession list. EB-2 and EB-3 green card sponsorship through PERM is also well-established in the oil and gas sector.
How do I find oil and gas companies that sponsor visas for reservoir engineers?
Migrate Mate lists employers with verified sponsorship history for engineering roles, including petroleum and reservoir engineering positions. You can browse by location and role type to find companies actively filing for candidates in your specialty, rather than applying broadly and discovering after an offer whether a company has a sponsorship program.
Does the H-1B cap affect reservoir engineers the same way it affects other workers?
Yes, unless your employer is cap-exempt. Most oil and gas companies, oilfield services firms, and engineering consultancies are cap-subject, meaning your petition enters the annual H-1B selection process. Universities and certain nonprofit research organizations are cap-exempt. The cap includes 65,000 regular slots and 20,000 reserved for advanced degree holders, and the selection rules have changed recently, so check current USCIS guidance before your employer files.
What degree background do U.S. employers expect for a sponsored reservoir engineer role?
Most employers and USCIS petitions are built around petroleum engineering degrees, but geosciences, geophysics, and chemical or mechanical engineering with significant reservoir-focused coursework also qualify. O*NET classifies reservoir engineering as requiring at least a bachelor's degree in a directly related field. If your degree title doesn't match standard expectations, you'll want an educational credential evaluation and supporting documentation before your employer files the petition.
What is the prevailing wage requirement for sponsored Reservoir Engineer jobs?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
