Reservoir Quality characterization and property distribution is key for Oil and Gas, and for Carbon Capture and Sequestration (CCS) projects. The intrinsic Multiscale Heterogeneity of carbonates adds complexity for the correct assessment of the most appropriate and fit for purpose reservoir property distribution in reservoir models. Moreover, capturing the right level of heterogeneity and connectivity of reservoir rocks changes through the Oil and Gas project life cycle (e.g. depletion vs. water or gas flooding), which requirements are in turn different to CCS projects.
This course reviews case examples and end-member scenarios of carbonate reservoir heterogeneity, while discussing how to depict the multiscale heterogeneity patterns in cores and logs, to assess/apply process-based rules and to enable flow unit correlations. The role of multiscale heterogeneity and its relevance for injection projects and potential impact on early breakthrough (including CCS projects) is discussed. Carbonate reservoir rock typing supports the distribution of rock properties in static models, and upscaling into dynamic models. In this course, several rock typing methods applied to carbonates are reviewed and assessed on end-member carbonate reservoir scenarios.

Duration and Training Method
As a classroom/virtual option this course includes a mixture of lectures and discussions, including case studies. Case examples provided by participants will be used if data sets are made available in advance. Individual / group exercises are inculded in the classroom option.
Course Overview
Learning Outcomes
Participants will learn to:
- Analyze the main depositional and diagenetic processes that control multiscale heterogeneity in carbonates.
- Assess pore structure heterogeneity and its impact on fluid flow, using novel digital tools for characterizing pore systems and rock properties.
- Evaluate mineralogical heterogeneity and its relevance to CCS projects, particularly in relation to reactions and mineralization processes.
- Correlate core and log data through specifically selected case examples, identifying key reservoir characteristics.
- Examine potential reasons for mismatches between core and log porosity, considering factors such as thin layers, patchy cement distributions, and varying rock types.
- Classify rock types using Lucia’s and Lonoy’s frameworks, incorporating participants' examples when available for practical analysis.
- Interpret porosity, permeability, and capillary pressure (Pc) data, focusing on their distribution, correlation, and upscaling implications for flow dynamics.

Who Should Attend and Prerequisites
This course is relevant/aimed to subsurface professionals working on carbonate assets and/or on CCS projects. The course is aimed to providing straightforward tools to enable the characterization of multiscale heterogeneity of carbonates, which is of significant relevance for flow (O&G and CCS/injection projects).
Instructors
Arve Lønøy
Background
Arve Lønøy is a carbonate geologist with extensive experience in research, exploration, and production/field development within both carbonates and siliciclastics. He worked at Norsk Hydro and Equinor from 1981 to 2011, focusing on reservoir characterization through the integration of geology, petrophysics, and reservoir engineering. Since 2011, he has been an independent consultant, developing and implementing predictive tools for reservoir characterization for numerous companies.
Lønøy has worldwide experience with carbonate reservoirs from various geological periods. His expertise includes core description, thin-section analyses, pore typing, characterization of flow units, reservoir zonation, well correlation, and integration with petrophysics and reservoir engineering. He has also worked on predicting pore types and reservoir properties from wireline logs using neural networks, conducting fieldwork studies, and promoting interdisciplinary integration.
He has built a global database on reservoir properties and developed a novel pore-type classification system, published in the AAPG Bulletin in 2006. This database has been the foundation for numerous predictive tools for reservoir characterization, tested and proven in both siliciclastic and carbonate reservoirs worldwide.
Lønøy is also experienced in training, having run geology courses at Norwegian universities and organized numerous courses and field trips for Equinor and other companies and institutions.
