Title: CO₂ Storage Potential on the Norwegian Continental Shelf
In this inaugural CSSR webinar, researcher Trine Mykkeltvedt presents a powerful new screening tool designed to evaluate the CO₂ storage potential of depleted hydrocarbon fields on the Norwegian Continental Shelf (NCS). Built on publicly available data, the tool offers an interactive way to assess indicators for properties like storage capacity, injectivity, and field expected lifetimeacross 134 hydrocarbon fields. With open access to the data and code, this tool enables researchers, policymakers, and industry stakeholders to do an early stage screening for CO₂ storage candidates on the NCS.
Summary: Trine Mykkeltvedt presented a screening tool developed within the Local Net Zero focus area of the CSSR (Center for Sustainable Subsurface Resources). The tool is mainly developed by senior researcher Alexey Khrulenko, and uses publicly available data to evaluate the CO₂ storage potential in depleted hydrocarbon fields on the NCS.
Key points from her talk:
- the tool uses data from the Norwegian Offshore Directorate FactPages and DISKOS to estimate indicators and visualize them in a web-based application,
- indicators for storage capacity, injectivity, field expected lifetime, and more,
- can identify promising fields for CO₂ storage based on user-defined criteria,
- valuable first-stage screening method for researchers, policymakers, and industry stakeholders.
- the underlying data and code are open access, encouraging further development and collaboration.
For Everyone: What Does This Mean?
The talk introduced a new screening tool designed to identify which depleted offshore oil and gas fields on the Norwegian Continental Shelf could be suitable for long‑term CO₂ storage. Using openly available geological and production data for 134 hydrocarbon fields, the tool calculates key indicators such as estimated storage capacity, how easily CO₂ can be injected, and how long a field is expected to remain viable. These indicators are presented in an interactive web‑based interface that allows users to filter, compare, and explore fields based on criteria relevant to their needs. The tool provides a practical first step for evaluating potential CO₂ storage sites and is intended to support researchers, policymakers, and industry decision‑makers. Because both the underlying data and the code are openly accessible, the approach encourages collaboration and further development across the CO₂ storage community.
