We invite you to bring your ideas to ExxonMobil to help create sustainable solutions that improve quality of life and meet society’s evolving needs. Learn more about our What and our Why and how we can work together.
What role you will play in our team
We are looking for experienced engineers with minimum 3 years in the upstream oil and gas industry, who will drive innovation and conduct reservoir simulation studies to support ExxonMobil’s global portfolio of Deepwater, Conventional, Heavy Oil & Unconventional assets.
What you will do
- Build computational models and simulations using proprietary and vendor tools to develop new technologies, enhance design and operational practices and address evolving business needs.
- Build or update high fidelity reservoir simulation models, history-match using available field data, and forecast dynamic predictions using calibrated models
- Perform data QA/QC and correct anomalies, analyze trends to recognize deviations and inconsistencies
- Interpret field experimental data (DAS/pressure/tracer data) and generate data driven insights to evaluate technologies and provide inputs to business decisions
- Conduct fit for purpose reservoir simulation analysis to accurately predict dynamic performance and provide appropriate technical inputs to support business decisions like workovers, infill drilling, facility capacity & operational thresholds, field development and reserves estimation
- Quantify subsurface uncertainties using multi scenario modeling methods
- Conduct research and development on new technologies, methods, or best practices using simulation models to provide engineering design recommendations for business decisions.
- Work closely with global business units and central capability groups to integrate geologic, reservoir and production data into reservoir simulation models, conduct or coordinate reservoir studies to robustly assess dynamic performance of our conventional, heavy oil, unconventional and carbon storage reservoirs
