Effective Cementing Solutions for CCS Wells

Disciplines: Completions | Drilling | Management

Course 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.
