support team lead
Chevron produces energy to meet the world’s needs, but Chevron itself is a product of its workforce and ingenuity. The “Day in the Life” series showcases that ingenuity, our Human Energy, at work across the breadth of our businesses. Through this series, we highlight the people that make our company unique, as they give us an insider’s look at their work days and share a bit about their lives at Chevron.
day in the life: reservoir simulation support team lead
What do petroleum engineers, computer scientists, mathematicians, physicists and chemical engineers have in common? They all play a vital role in Chevron’s reservoir simulation workflow support team.
Barış Güyagüler leads this team, which helps create computer-based models for the fluids and rocks in subsurface reservoirs. These sophisticated models are used to forecast various development scenarios to help decide how best to develop the field – what facilities will be needed, where the wells go, how the wells will be designed and how the reservoir will be managed.
“Reservoir simulation is an essential piece of delivering energy.”
Measurements are taken in the field and used to build computer models to create a virtual oilfield. The first part is to reproduce what’s actually happening in the field with its virtual counterpart – for example, the team models how fluids are injected, how the reservoir is produced, how its pressure and temperature changes. Once that part is done, the team can experiment with hypothetical scenarios, such as drilling for a new well, and carry out various economic analysis based on those scenarios.
“Reservoir simulation is a very powerful tool in making investment decisions.”
Barış enjoys the mystery of following clues to slowly and logically get to the final resolution of an issue. Interaction with business unit engineers can be as short as a ten-minute conversation, to a week or months, requiring multiple people and multiple units working together towards the
solution. Once that issue is resolved, Barış and his team can help their business unit partners make decisions that will lead to more successful economic outcomes. Chevron has over 60 simulation centers, and Barış’ team responds to these communications globally, exposing him to a variety of cultures and highly motivated colleagues.
Reservoir simulation is not a new discipline, but it is always evolving and improving due to the need to model new physical processes for increasingly complex reservoirs – keeping the job challenging, but rewarding.
“Developing new formulations, numerical schemes and software architecture makes Chevron a leader in reservoir simulation.”
