General
Course Summary
This following three courses (SPC5030, SPC5031 & SPC5032) will provide participants with an awareness and understanding subsurface of CO2 storage, CO2 flow in the subsurface, and the key issues of reservoir depth, well design, reservoir lithology and quality, in realtion to CCUS. SPC5030 will provide participants with awareness and understanding of the subsurface needs of CCS projects. It will establish basics such as how much CCS is needed to make a difference to global warming and explore what types of CO2 injection. SPC5031 will address the awareness and understanding subsurface CO2 storage volumetrics, CO2 flow in the subsurface away from injector wells, the objective of permanent and safe storage of CO2, and the key issues of reservoir depth, well design, reservoir lithology, reservoir quality, and reservoir architecture. Finally, SPM5032 will consider the range of potential leakage mechanisms that need to be assessed. It will include a detailed consideration of the monitoring strategies available to assure the safety and integrity of the CO2 storage site.
Example Learning Outcomes
- Appreciate the types of CO2 injections projects have occurred so far, and the ones that are planned.
- Discuss CCS projects that have been a success and those that have had problems.
- Build awareness of the reservoir rocks that store CO2 and the volumetrics of CO2 storage.
- Appreciate the importance of the storage efficiency factor in controlling how much CO2 can be injected.
- Gain an appreciation of the question of the injectivity of CO2 and the roles of permeability and aquifer architecture on CO2 flow.

SPM1033
CO2 in the atmosphere and options to cut CO2 emissions
This module outlines the history of greenhouse gases, explores CO2 emissions and how CO2 emissions can be cut. Learning outcomes include; an understanding why we need to reduce the CO2 in the Earth's atmosphere, a realisation of the time scales we need to work to cut greenhouse gas emissions, an appreciation of where the emitted CO2 derives from, and finally you will develop an understanding of where carbon capture and storage fits into the range of strategies that are being adopted to cut greenhouse gas emissions.

Geological CCS, CCS as mitigation strategy
This module outlines geological storage options for CO2 and CCS as a mitigation strategy. Learning outcomes include understanding the main geological options for CCS, develop an appreciate the objectives of geological (and engineering) activities required during CCS projects. You will also start to develop an appreciation of what CCS projects have been developed so far, how much CO2 is locked away annually now and how much more CO2 must be locked up annually to mitigate global warming and finally appreciate the range of industrial activities that need to engage with CCS and knowledge of some of the main CCS projects in operation.

CO2-EOR and CCS: fate of CO2 in the subsurface
The aim of this module will primarily be to look at CO2 injection projects related to enhanced oil recovery, and the fates of CO2 in the subsurface. By the end of this module you will be able to appreciate what CO2-Enhanced Oil Recovery (EOR) is, to realise the planned role of CO2 hubs and clusters to facilitate large-scale CCS, start to understand storage capacity for CO2 (in a depleted oil field), as well as understand what happens to CO2 when it is injected into the subsurface and appreciate that CO2 injections rates are unlikely to be constant and that the injected gas may not be pure CO2.

CO2 phase behaviour and properties, CO2 trapping
The aim of this module will be to examine how CO2 occurs in CCS sites and how phase behaviour is associated with pressure, temperature and water salinity. The module will also expand on CO2 characteristics to appreciate what happens to water chemistry at high CO2pressures in addition to understanding how CO2 becomes trapped in the sub-surface despite its buoyancy compared to water.

CO2 storage volumes and controls on porosity in sandstone reservoirs
Over the duration of this module, we will explore a range of depositional, early diagenetic, and burial diagenetic factors that influence reservoir properties in sandstone reservoirs. As we explore these primary (deposition) and secondary (early and burial diagenesis) factors you will gain an appreciation of the reasons for porosity in sandstone reservoirs. Finally, we will explore the range and types (primary or secondary) of porosity in sandstone reservoirs.

CO2 storage volumes and controls on porosity in carbonate reservoirs
During this module, we will explore a range of depositional, early diagenetic, and burial diagenetic factors that influence reservoir properties in carbonate reservoirs. As we explore these primary (deposition) and secondary (early and burial diagenesis) factors you will gain an appreciation of the reasons carbonate reservoirs tend to have lower porosity than sandstone reservoirs. Finally, we will explore the range and types (primary or secondary) of porosity in carbonate reservoirs.

Risk and rate of mineral dissolution due to CCS: calcite in sandstones and limestones
Over the duration of this module, we will explore the risks and rates of mineral dissolution due to carbon capture and storage. Our focus will be primarily on the dissolution risk of carbonate minerals in sandstones and limestones, but we will also discuss other minerals. We will discuss dissolution modeling and how these techniques can be used to enhance our understanding of CCS project risks. Finally, we will look at some field and lab based examples where dissolution has been caused by CCS.

CO2 storage efficiency
This module will explore the phenomenon known as CO2 storage efficiency. CO2 storage efficiency is a very important parameter that controls how much carbon dioxide can be stored at any given site in the subsurface. We will discuss the factors that affect storage efficiency and how these factors vary in saline aquifers and depleted oil and gas fields. Finally, we will discuss some methods to determine CO2 storage efficiency.

CO2 risk of leakage from CCS sites and borehole issues
In this module, you will learn about CO2 leakage risks from CCS sites, focussing initially on generalities, then moving on to leakages through intact-top seals and then leakage via old wells. Appreciate that loss of CO2 to atmosphere and understand that top seal effects, well effects, and fault and fracture effects can conceivably all lead to escape of CO2
