Course Overview

Interest in carbon capture and storage (CCS) is growing rapidly as a crucial part of global efforts to reduce greenhouse gas emissions into the atmosphere. To support this growth in capture technology, we need an acceleration in new CO2 storage project developments. In this course, we review the science and technology underpinning CO2 storage in deep saline aquifer formations using insights from several industrial-scale projects. We analyze the main factors, which limit storage capacity — constraints governed by flow dynamics, injectivity, pressure development, and geomechanics. Then, this physical basis provides a framework for determining how to optimize monitoring methods.

Using the latest portfolio of geophysical methods for smart and cost-effective monitoring at the surface and downhole (including conventional seismic acquisition, passive seismic listening, and fiber-optic sensing), we discuss how short- and long-term storage assurance can be demonstrated with high levels of confidence.

Next, we address the question of what is needed to achieve climate-significant scales of CCS deployment. Although technically achievable, the current socio-economic framing often makes storage project execution difficult in practice. By building technical confidence in project execution, we may be able ‘turn the dial’ and realize the gigatonne levels of storage needed over the coming decades.he examples range from conventional to unconventional production, through geothermal energy extraction to CO2 sequestration (CCUS). It allows professional understanding of the currently available methods and measurements made in passive seismic monitoring, their use and uncertainties associated with measurements. 

Examples of microseismicity monitored with the DAS monitoring systems, source mechanisms and tomography to reservoir simulations are discussed and assessed. Social and scientific aspects of induced seismicity related to energy industry will be also discussed.

Course Objective

  • The goal of this course is to review the main concepts involved in the engineered storage of CO2 in saline aquifer formations, dispelling some common misunderstandings along the way. After explaining the main trapping mechanisms, we critically assess methods for estimating storage capacity and evaluate the key constraints for achieving the storage volumes needed over the project’s timeframe. The course material has a strong focus on geophysical monitoring methods and data sets, which are key to the stated objective of building confidence in the technology and assuring long-term storage integrity.

Course Outline

Chapter 1:  Main processes involved in the geologic storage of CO2

Chapter 3: Understanding the constraints to storage          

Chapter 4: Optimizing geophysical monitoring methods

Chapter 5: Global scale-up potential and future challenge

Participants’ Profile

All those interested in understanding the state of play in saline aquifer CO2 storage technology will benefit from this course. The primary target audience is multi-disciplinary subsurface teams, and the content covers relevant aspects of geoscience, geophysics, and reservoir engineering. Managers, team leaders, and business developers also should find most of the material accessible. For subsurface specialists, the focus is on learning across disciplines (e.g., how might flow analysis affect site selection choices or how do ‘geological details’ impact the engineering assessment?).  With a strong focus on advanced geophysical monitoring (especially time-lapse seismic), geophysicists will find the course helpful for designing and interpreting seismic monitoring data sets. This course does not require advanced mathematical knowledge, although several governing equations are introduced and used. The main objective is to provide an intuitive understanding of the geoscience, physics, and geophysics of CO2 storage in saline aquifers. 

Prerequisites

A familiarity with integrated 3D subsurface modeling and seismic interpretation tools will be an advantage but is not essential.
