What is the difference between Temporary Reservoir Simulation Engineer vs Reservoir Engineer?

AspectTemporary Reservoir Simulation EngineerReservoir Engineer
CredentialsBachelor's or Master's in Petroleum Engineering or related field; familiarity with simulation softwareBachelor's or Master's in Petroleum Engineering; professional engineering license often preferred
Work EnvironmentProject-based, temporary assignments in oil and gas companies or consulting firmsLong-term employment within oil and gas companies or consulting firms
Industry UsageUsed during specific reservoir modeling projects or simulationsInvolved in ongoing reservoir management and production optimization

The Temporary Reservoir Simulation Engineer focuses on short-term, project-specific reservoir modeling tasks, often working temporarily on simulations. In contrast, Reservoir Engineers typically have ongoing roles managing reservoir performance and production over time. Both roles require similar technical skills but differ mainly in duration and scope of employment.

What are the key skills and qualifications needed to thrive as a Temporary Reservoir Simulation Engineer, and why are they important?

To thrive as a Temporary Reservoir Simulation Engineer, you need a strong background in petroleum engineering, fluid dynamics, and numerical modeling, often supported by a relevant engineering degree. Proficiency in reservoir simulation software such as Eclipse, CMG, or PETREL, and familiarity with data analysis tools is typically required. Strong analytical thinking, problem-solving abilities, and effective communication skills set candidates apart in this role. These competencies are crucial for accurately modeling reservoir behavior, optimizing production strategies, and supporting team decision-making in short-term project environments.

What are some common challenges faced by Temporary Reservoir Simulation Engineers when integrating new models into existing workflows?

Temporary Reservoir Simulation Engineers often encounter challenges such as aligning new simulation models with legacy data and established workflows, ensuring model accuracy within tight deadlines, and adapting quickly to diverse software platforms used by different teams. Since the position is temporary, engineers must rapidly understand the reservoir characteristics and project objectives while communicating effectively with geologists, production engineers, and IT specialists. Proactive collaboration and strong documentation skills are essential to ensure a smooth handover and integration of simulation results into ongoing reservoir management strategies.

What are Temporary Reservoir Simulation Engineers?

Temporary Reservoir Simulation Engineers are professionals hired on a short-term basis to analyze and model the behavior of fluids within oil and gas reservoirs. They use specialized software to simulate reservoir performance, assist in optimizing production strategies, and provide technical support for field development planning. Their work helps companies make informed decisions about drilling, production, and reservoir management. Temporary roles typically fill gaps during peak project periods or when specialized expertise is needed for a specific timeframe.

Senior Geothermal Reservoir Engineer

Zanskar

Salt Lake City, UT • On-site, Remote

Full-time

Posted 22 days ago

Job description

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 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
