Workshop 2

Workshop 2 – 8 November – 9:00 – 16:00

CCS AND GEOTHERMAL AT ITS CORE: GEOLOGICAL RISK ASSESSMENT FOR GEOTHERMAL AND CCS ON CORE MATERIAL

Description

Are you fascinated by the potential of sustainable energy solutions in the deep subsurface and the science behind them? Join the EAGE GET24 workshop at PanTerra for an immersive, set of lectures, hands-on core viewing and discussions that delves into the Carbon Capture and Storage (CCS) and geothermal energy.

This workshop is tailored to a broad audience in the energy sector, from entry-level to experienced environmental professionals, geologists, energy sector specialists, and anyone passionate about advancing sustainable energy practices.

In this workshop you will visit the PanTerra laboratory, to view the EBN Amstelland and Oranjeoord cores in detail yourself. These cores have been acquired as part of the EBN SCAN program. In addition, you will also be offered to inspect other core material which is studied for CCS projects. In addition, core material relevant caprocks will be on view. Moreover, you will receive a tour with an explanation of relevant lab equipment for special core analysis and core flooding, which is being used for Geothermal and CCS studies.

The program starts with a discussion on the general risks for Geothermal and CCS developments, and during the core viewing you can assess some of these risks yourself by inspecting the core.

CCS WORKSHOP

Focus of the workshop: using small scale observations from core material to answer risk related questions in a larger scale CCS operation.

General introduction to CCS

Accessible introduction done by an (inhouse) expert on the geological aspects of CCS. The key focus here is in the geological risks for CCS. The following can be introduced:

  1. The different components of a storage complex: reservoir, caprock(s), (wells)
  2. Geological properties of the storage complex components, what defines a good storage site?
  3. Introduction to the core handling part of the workshop

Regardless of the prior knowledge of the attendee, an expert will provide a baseline for the workshop and preparing the attendee for the core handling exercise.

Core handling exercise

The group will be divided into groups of three attendees. If the total group size is limited, the workshop can be held with the group as a whole. The groups could preferentially contain at least 1 experienced geoscientist and less experienced attendees. Each group will get a core sample, including a reservoir, and a caprock sample. Following the introduction, the attendees are invited to study the core samples and discuss within the group how the rock properties would impact a CCS operation. Observations such as:

  • Mineralogy
  • Sedimentary features
  • Porosity/permeability
  • Heterogeneities

Group discussion 

Following the core handling exercise, the groups are invited to give a brief outline of their observations. A list of the observations per component of the storage site is created. This will be used to hold a group discussion on the various rock properties with respect to risks in CCS. The centralized question here is: do the rocks in this case study make for a good storage candidate?   

A link between observations in the lab and the risks of storage sites will be made – but also the limitations: what observations cannot be done on a small scale core? How can other studies, such as lab tests, contribute to providing answers? Do more in depth lab studies confirm the core observations?

In addition, a link between CCS and Geothermal risks and observations will be made. 

GEOTHERMAL WORKSHOP

Focus of the workshop: using small scale observations from core material to answer risk related questions in a larger scale GT operation

General introduction to GT

The key focus here is in the geological risks for Geothermal. The following will be introduced:

  1. Different types of geothermal reservoirs: high perm sediments or fractured rocks
  2. Geological properties of the reservoir, what defines a good Geothermal reservoir? These involve flow rates, heat in place etc.
  3. Impact of GT operation on subsurface over operation lifetime
  4. Introduction to the core handling exercise
  5. EBN will give an introduction to the SCAN project, of which cores are studied during the workshop.

Regardless of the prior knowledge of the attendee, a baseline for the workshop will be provided to preparing the attendee for the core handling exercise. 

Core handling exercise

The group will be divided into groups of three attendees. If the total group size is limited, the workshop can be held with the group as a whole. The groups of three attendees could preferentially contain at least 1 experienced geoscientist and less experienced attendees. Each group will get a core sample of a potential geothermal reservoir. Following the introduction, the attendees are invited to study the core samples and discuss within the group how the rock properties would impact a CCS operation. Observations such as:

  • Mineralogy
  • Sedimentary features
  • Deformation features
  • Porosity/permeability
  • Heterogeneities

 

Group discussion with the expert

Following the core handling exercise, the groups are invited to give a brief outline of their observations. A list of  observations per component of the geothermal reservoir is created. A group discussion on the various rock properties with respect to risks in Geothermal will be held. The centralized question here is: do the rocks in this fictive case study make for a good Geothermal energy reservoir?  Further questions: What are the contrasts between different reservoir types? Were any features missed? What observations cannot be done on a small scale core? 

A link between the core viewing and risks will be made: what observations cannot be done on a small scale core? How can other studies, such as lab tests, contribute to providing answers? Which in depth studies can confirm the core observations?

A link will be made between Geothermal and CCS risks – and it will be discussed which risks are similar or different between CCS and Geothermal.

In 2012 he has joined SLB and since then has been developing interpretation workflowsand answer products for surface formation evaluation (mud gas and cuttings logging). Since couple of years his works involves H2 and helium logging and exploration, for which the global activity is rapidly growing.

This topic also brings ideas of stimulated natural H2 in the subsurface, which brings together geological and fluid geochemistry knowledge to a new level of collaboration among academic and industrial communities.

Dariusz is very active within the geochemistry community, with multiple peer-reviewed papers and chapters, numerous conference-related activities, journal editorships, and intellectual property publications.
