Reservoir Simulation information
Is reservoir simulation a good career?
What are the key skills and qualifications needed to thrive as a reservoir simulation engineer?
What is the difference between Reservoir Simulation vs Reservoir Engineer?
| Aspect | Reservoir Simulation | Reservoir Engineer |
|---|---|---|
| Primary Focus | Developing computer models to predict reservoir behavior | Analyzing reservoir data to optimize production |
| Required Skills | Petroleum engineering, reservoir modeling, software proficiency | Reservoir analysis, production forecasting, data interpretation |
| Work Environment | Engineering teams, software development, simulation labs | Field operations, data analysis, project planning |
| Certifications | Petroleum Engineering degree, software certifications | Petroleum Engineering degree, professional licenses |
Reservoir Simulation involves creating models to predict reservoir performance, while Reservoir Engineers analyze data to optimize extraction. Both roles require petroleum engineering knowledge but focus on different aspects of reservoir management.

HDR is looking for a water resources engineer to join as a team leader within our Hydrology and System Operations Section team in Sacramento, CA and assist in staff development and project delivery. This position is well-suited for an experienced water resources professional with a strong technical foundation and increasing responsibility in project delivery, client interaction, technical leadership, and staff development. The ideal candidate will bring depth in reservoir system operations, hydrologic and hydraulic modeling, watershed hydrology, and climate change analysis, and will contribute meaningfully to team leadership and mentoring.
Our clients include local, state, and federal agencies, and our work spans some of the most complex and high-profile water resources challenges in California and the western U.S. The selected candidate will play a key role in project execution, staff development, and the delivery of high-quality technical work across a diverse portfolio.
Skills such as scripting (such as WRESL, Python/Jython, or VBA) and experience with CalSim II and CalSim 3, CalLite, VIC, HEC software (such as HEC-SSP, HEC-HMS, HEC-ResSim and both HEC-RAS 1D and 2D), water temperature modeling (HEC 5Q, CE QUAL W2), climate change analytical tools and datasets (such as Global Circulation Models and downscaling methods), linear programming and optimization would be considered beneficial.
The candidate is expected to be a key part of project delivery teams; mentor junior staff; manage small- to medium-sized projects; and effectively interact with clients and peers. Candidates should be able to work independently but also enjoy working in a collaborative team environment. The candidate must have strong writing skills and good quality control/quality assurance processes.
