The Digital Twin for Production Optimization With Emphasis on Compositional Modeling
So far, digital twins have focused mainly on mimicking small, well-defined systems. Integrated asset models, however, tend to address the bigger picture. In this video, Distinguished Lecturer Kristian Mogensen addresses whether we can take the best from both worlds, whether we need to, and how to go about developing such a technical solution.
A digital twin is essentially a digital representation of a physical system such as a well, pump, compressor, or a series of connected items. Sometimes, machine-learning algorithms can assist in analyzing large amounts of data within domains such as preventive maintenance.
The value proposition of a digital twin is to have a complete overview of all fluid streams in the production and injection network to enable automation of production capacity planning subject to current and future constraints. The digital solution must be versatile, maintainable, accurate, and with a quick turnaround time to address dynamic changes in market demand as well as the supply side down to the individual wells.
Integrated asset models (IAM) have been around for the past 2 decades or so. These models have become more sophisticated but also require more effort to maintain. The digital oil field (DOF) orchestrates data exchange between different information technology systems to feed a calibrated IAM model. An IAM/DOF system provides an up-to-date overview of all fluid streams to maximize value creation subject to a number of constraints.
So far, digital twins have mainly focused on mimicking small, well-defined systems, whereas IAM models tend to address the bigger picture. Can we take the best from both worlds? Do you need to? And how would you go about developing such a technical solution?
Distinguished Lecturer Kristian Mogensen discusses some of these aspects in this SPE Live. When you blend different fluid systems together, you need a robust fluid description at well level. Complicating factors may arise, such as compositional variation at reservoir level, gas coning as well as breakthrough of injection gas. Many such technical details must be factored in, without losing sight of the overall goal: to create more value.
