Reservoir Characterisation and Simulation for CCS
Format and Duration:
2 days
3 sessions
In this course we will review the geological features of possible storage sites, focussing on the heterogeneity and presence of faults. This will enable an assessment of the impact of complex heterogeneous geology on the storage efficiency and security of the system in terms of the possible migration along faults that transect a reservoir, or through leaky seal layers. In modelling CO2, we will firstly consider the simulation objectives, the impact of aquifer properties, top and bottom seal diffusion, areal coverage of the pressure front, and secondary reservoirs for expansion. Various model approaches will be considered, namely, material balance, sector, full field, two-phase vs compositional, areal and stratigraphic coverage. The simulation of various development strategies will be tackled along with the long-term modelling of CO2 interactions and plume behaviour. The alternative approaches to the estimation of storage capacity will also be investigated.
Schedule
Duration and Training Method
A classroom or virtual classroom course comprising presentations, discussions, and case studies.
Course Overview
Learning Outcomes
Participants will learn to:
- Assess the potential for CO2 to leak or migrate across faults or through seal layers.
- Analyse the leakage rate in comparison with the injection and plume dispersal rate.
- Develop a simple model to test the impact of heterogeneity on CO2 storage efficiency.
- Frame simulation objectives according to whether storage capacity, integrity assessment, development planning, or operational monitoring are the strategic requirement.
- Select the appropriate model approach, development strategy, and long-term modelling of CO2 interactions and plume behaviour.
- Compare the various alternative approaches for estimating storage capacity.
Course Content
Assessment of rock heterogeneity, faults, and seal rock
- Geological features of possible storage sites, heterogeneity, and presence of faults
- Complex flow patterns whereby the buoyancy of the CO2 may cause rapid ascent through the formation,
- The potential for CO2 to leak or migrate across faults or through seal layers
- Assess the impact of complex heterogeneous geology on storage efficiency
- Security of storage in the system in terms of the possible migration along faults or through leaky seal layers.
- Consider the case study of the Sleipner reservoir, where the 9-layer system, with partially sealing horizons
- Introduce simple model to test the impact of heterogeneity on CO2 storage efficiency
Reservoir modelling and forecasting CO2 storage performance

Instructors
Pete Smith
Background
Pete Smith is Director of ReganSmith Associates, a company offering training and consultancy to the Oil and Gas Industry. Pete trained as a reservoir engineer and researcher firstly at the UK government research Institute of Hydrology, Oxford, before joining BP’s research team to lead the development of novel modelling methods; building the first stochastic models to describe multi-phase fluid-flow in reservoir rocks. Moving into BP operational activities, he was responsible for creating the processes for managing the uncertainty in value and reserves in new field developments that became the BP standard approach.
Assignments with BP included lead engineer on Dukhan, Arab C Reservoir, Qatar; the appraisal and financial sanction of the Harding, Andrew, Foinaven and Schiehalion fields in the UKCS and managing the operated production in the Gulf of Mexico. Pete was also the founding director of the BP Institute at Cambridge University concerned with fundamental research in fluid-flow and was responsible for building their environmental technology across the BP group as Technology Vice President.
Pete helped establish the new Engineering University in Trinidad & Tobago as Associate Provost (R&D) and Professor of Petroleum Engineering between 2004 and 2008. On return to the UK, Pete became Principal Advisor in Reservoir Engineering at RPS Energy leading company reserve audits. In 2010 Pete led the Upstream Risk Management advisory activity and in 2011 became Chief Reservoir Engineer.

Andy Woods
Background
Prof Woods completed his undergraduate and post graduate degrees at the University of Cambridge, focusing on mathematics and geological fluid flows. His early academic career included a Lectureship at the University of Cambridge, Institute of Theoretical Geophysics and Department of Applied Mathematics and Theoretical Physics and later Professor of Applied Mathematics at the University of Bristol. He was appointed BP Professor of Petroleum Science and Head, BP Institute, University of Cambridge in 2000, where he remains today.
Prof Woods is interested in modelling fluid mechanical processes in industry and the environment, including flows in porous media of relevance for oil production, CO2 sequestration, thermal energy storage and geothermal power production, as well as modelling turbulent flows associated with volcanic eruptions, oil blowouts, and hydrothermal plumes. He is also interested in modelling air and heat transfer in buildings, including the effects of natural convection and ventilation and the use of labyrinths for diurnal and interseasonal heat storage. His work combines laboratory experiments, theoretical models and where appropriate numerical simulations.
