The amount of CO₂ that can be stored in underground reservoirs is often summarised by the Storage Efficiency ‘E’. Storage Efficiency is a key factor - but its calculation is arguably complicated as E is impacted by lithological heterogeneity, trapping structures, boundary conditions, injection rates, well spacing, fluid properties etc.

Due to this complexity, there is much controversy on how to estimate E, with some arguing it should not be used at all and that reservoir simulation is a better path. However, estimates for E are used in most regional mapping studies, and applicability of these screening estimates to project specific Storage Efficiency studies is unclear and potentially misleading.​

The industry needs a consistent and multidisciplinary approach for using storage efficiency estimates in storage capacity studies, as well as guidelines for when this measure is useful in the process of maturing CO₂ storage prospects towards investment decisions.​

This convention aims to bring together industry and academic experts to establish improved workflows or tables for the calculation of Storage Efficiency. The ultimate objective is to come up with a set of procedures on how to define that crucial E number, and to develop guidelines for when it should be used.​

This two-day event will be a mix of keynote talks, 5-minute poster pitches, and panel discussions.

Call for abstracts and guidelines to frame your abstract submission

Please submit abstracts for oral and poster contributions to [email protected] before 15 July 2023

We are looking for the convention to broadly address approaches to estimating storage efficiency factors, be that a simple look-up table, or a detailed site-specific modelling effort. We look to explore what geologic and engineering factors impact storage potential; how these are included in the efficiency calculation; which methodologies are most applicable at different length scales and how this can be applied at different stages of project life.

The presentations should offer a range of perspectives that, as a whole, will enable the participants to effectively address these questions.  We hope that the above guidance is helpful for framing your submission.
