Location Middletown, California
Date Posted October 4, 2015
Category Reservoir Engineer
Job Type Permanent


Requisition Number 15-0173 Title Reservoir Engineer City Middletown State CA Job Family Commercial Analytics Shift Days Employee Type Regular Subject to DOT Regulations No Percent of Travel Required 0 Relocation Provided No Location Geysers Description Calpine’s Geothermal Production Analysis group develops views of production trends for the world’s largest operating geothermal field, The Geysers in Northern California. Relying heavily on input from the broader Geysers operations team, the production analysis group builds models to project output from the existing field, analyze the impacts of long-term capital investment options, and optimize near-term production decisions.

The Reservoir Engineer will work as part of the Geothermal Production Analysis team in analyzing production and injection data, developing data-management improvement recommendations, conducting reservoir and steam gathering system performance evaluations for optimum field development and building simulation models for field performance studies. The ideal candidate will have had experience in data-driven analytics for reservoir and production optimization. We are particularly interested in individuals who have experience translating the outputs of numerical simulation into field operations.

Essential Duties and Responsibilities will include some or all of the following:

• Reservoir modeling of hydrothermal systems:
o Use of advanced flow modeling software for probabilistic history matching, forecasting, and optimization
o Guide workflows, with the reservoir engineering and geoscience teams
• Build and maintain calibrated numerical simulation models of the reservoir-pipeline-power plant geothermal system.
• Use simulation model to forecast steam flows under different operational scenarios.
• Provide support on forecasts of future capital improvements, generation and revenues.
• Maintain comprehensive, up-to-date knowledge of reservoir data and technology relevant to Geysers field management.
• Participate in the evaluation of exploration, development and acquisition opportunities.
• Maintain general awareness of other geothermal fields and regions.
• Use advanced data mining, pattern recognition and machine learning to reservoir modeling, history matching and production optimization.
• Work location is in Northern California (at The Geysers facility with some flexibility to work in Calpine’s West Region office in Dublin, California)

Requirements • A bachelor or graduate degree in geology, gas/oil/geothermal reservoir engineering or computational/data science from an accredited university is required.
• Analytical/technical skills with a practical approach to problem solving.
• Familiar with data-management systems (e.g. SQL, SQLite, Microsoft SQL server, Microsoft Access, geodatabase etc)
• Familiar with geological and reservoir engineering applications (e.g. GOCAD/SKUA, Petrel, Eclipse, VIP, Tetrad, STAR, TOUGH2, etc)
• Experience in programming languages (e.g. Fortran, C\C++, Python, etc)
• Comfortable operating in a data-intense environment.
• Familiar with the IT/IS aspects of reservoir modeling; skilled with commercially available reservoir modeling applications and/or proprietary model development.
• Experience in geothermal production strongly preferred.
