    Description: Effective Cementing Solutions for CCS Wells is a half-day Training Course that will focus on the challenges of completing and cementing Carbon Capture and Storage wells. For CCS wells, the design should start with the completion size required to achieve the desired CO2 injection rate. Dual containment is essential; the second barrier must not only be designed for the corrosive environment but the second barrier and its associated equipment must be periodically inspected or tested. The differences between CCS wells and conventional oil and gas wells require a different approach to well design. If CCS wells were to be designed using established methods for oil and gas, the wells might fail to maintain integrity to prevent undetected migration of stored CO2.
    Cementing CCS wells has many inherent corrosion-resistant challenges to mitigate risk. These include:

    1. Need for maximum cement coverage to ensure zonal isolation.
    2.  Requirement for long endurance during exposure to supercritical CO2. CO2 and critical CO2 create strong acid environments with water in the reservoir which attacks and degrades normal Portland-based well cementing systems.
    3. Safeguarding a salt Interval or sealing caprock zone is critical for well design and sealing.
    4. Injection formation intervals with high permeability and lower pressure profiles for injection potentially increase the risk for hole stability and losses.

    Cement technologies, alternatives, and new solutions maximize zonal isolation and stabilize and reinforce the well to mitigate risks such as gas migration, cement deterioration, or corrosion.

    Legacy wells are present in most potential CCS fields. In this session, we will discuss issues involved with performing a risk analysis for leakage of legacy wells. While the focus of this session will be on leakage through cement, other potential leak paths will be discussed.

    Chairs: David Stiles, ExxonMobil; Tracy Moffett, ExxonMobil

    Presentations:

    • The Role of Simulation in Assessing Leakage through Legacy Wells
      Deepak Datye, Dassault Systemes
    • Considerations for Risk Assessing Legacy Wells on Land
      Marco Troiani, ExxonMobil
    • A Screening Framework for Evaluating Legacy Offshore Wells in the Gulf of Mexico for Geologic Carbon Storage

    In this session we will discuss what options we have for remediation and abandonment of legacy wells once they are identified and assessment for leakage is established, which is covered in the Screening and Risk Analysis for Legacy Well Leakage session. Collection of field data on the history and the current state of wellbores, as well as future plans for the fields, will influence the choice to abandon or repurpose.

    Injecting and storing captured CO2 in subsurface reservoirs requires a thorough understanding of the impact of injected CO2 on cement in purpose-built wells (injection/monitoring) and legacy wells (active, and/or abandoned). This session will provide an overview of the current state of the knowledge of cement/CO2 interactions and the impact to well integrity in storage scenarios. Topics of interest include mechanical and chemical properties of CO2-altered cement, effectiveness of self-sealing behavior, ability of cement to protect the steel casing from corrosion, and thermal impacts of injecting cold CO2 on cement performance. In addition, this session will address future needs to ensure safe and economic storage of CO2.

    This session will investigate the state of the regulatory requirements and solutions to those requirements around cementing in Class VI well applications. This includes both primary cementing of the injection and monitoring wells and the remedial applications for corrective action on existing artificial penetrations.

    With CCUS becoming more commercially viable, selection of materials to provide robust annular barriers will be crucial to ensure long term integrity across decades of injection cycles and corrosion. Unlike the standardized testing and analysis practices in place today for oil and gas wells construction, to date, there are no such agreed upon best practices in place for the construction of CCUS wells. This session will review a variety of exposure and analysis techniques to measure and predict permeability, porosity, and mechanical properties of cementitious materials in order to reduce risk and gain alignment within the industry.

    For this session, the workshop participants will be split into approximately seven small groups. Each group will be assigned a topic that has been captured during the Workshop. The objective will be to brainstorm ideas and evaluate possible solutions. The deliverable will be to present a suggested path forward for each topic. Each group will present their conclusions to the audience, with the possibility for additional discussion.
