CO2 sequestration is unlocking new opportunities for the oil and gas industry, but success hinges on overcoming the challenges of carbon capture, utilization, and storage (CCUS). With the right expertise in drilling and wellsite management, these obstacles can be transformed into cost-saving, efficient solutions that drive progress in CO2 storage projects.
Key CCUS Challenges
When it comes to implementing CCUS technology, there are several key challenges that need to be addressed, particularly for the oil and gas industry. Let’s take a look at some of the major obstacles standing in the way of large-scale deployment, according to a recent JPT article.
Absorption technology, for example, is well-established but can consume up to 30% of the power generated by a plant, affecting overall efficiency. Direct Air Capture (DAC), while promising, is even more energy-intensive, with costs ranging from $300 to $700 per ton of CO2 removed. These combined factors can make it difficult to scale CCUS efficiently.
To bridge this gap, large-scale storage solutions are essential. Since industrial applications alone cannot manage the excess CO2, underground storage in formations like aquifers or depleted reservoirs must be developed further, requiring significant infrastructure investment.
3. CO2 Storage
CO2 storage in aquifers and depleted hydrocarbon reservoirs holds great potential, but each option presents challenges.
Aquifers offer vast storage capacity, though sealing to prevent leakage requires complex geological analysis and long-term monitoring. Depleted hydrocarbon reservoirs, already well-mapped from past production, present a reliable option for CO2 injection, but old wells must be sealed, and coordination with landowners is needed.
Subsurface mineralization is another promising method, as it converts CO2 into stable minerals within certain rock types. While pilot projects have been successful, scaling this solution will require further research and infrastructure investment.
Effective monitoring and geological assessments are key to making these storage methods viable.
4. CO2 Transportation
Transporting CO2 presents several challenges, particularly in managing pipeline corrosion. CO2 can become corrosive when water is present, forming carbonic acid that can damage steel CO2 pipelines. To avoid this, pipelines must be designed to handle dry CO2 with minimal water vapor.
Maintaining high pressure—above 1,300 psi—is also important to keep CO2 in a dense, liquid-like state, allowing for efficient transport over long distances. This pressure level enables the use of pumps instead of compressors, reducing both energy consumption and operational costs.
One of the major obstacles to widespread CCUS adoption is the lack of infrastructure in many regions. Building pipelines, storage sites, and capture facilities requires significant investment, but progress is often delayed by unclear regulatory frameworks.
In addition, economic incentives that would make CCUS financially feasible are often missing. Policies, tax incentives, and government support are necessary to drive the growth of this technology, but many areas still lack the necessary backing to move forward.
6. Public Acceptance
Public awareness and support are important for the success of CCUS projects. Without a clear understanding of the benefits and potential risks, it can be difficult to build the necessary support for large-scale initiatives. Educating the public and engaging stakeholders is key, particularly when discussing long-term storage and the significant infrastructure investment involved.
Addressing these challenges is necessary for the successful integration of CCUS in the energy sector. Solutions will require collaboration across industries, with a focus on innovation, infrastructure development, and policy support.
Drilling is fundamental to the success of CCUS projects, particularly in safely sequestering CO2 underground.
The oil and gas industry’s expertise in drilling techniques is integral for accessing geological formations that serve as long-term storage sites for captured CO2. The same drilling technologies used in hydrocarbon extraction are applied to create injection wells that allow CO2 to be stored deep beneath the surface.
A total drilling fluids program plays an important role in making these projects viable. This program includes a combination of drilling mud systems, solids control, haul-off and disposal services, and equipment rentals, all working together to maintain smooth operations.
These integrated services streamline the drilling process, support CO2 injection, and help minimize operational downtime. With the established technologies and capabilities from the oil and gas sector, CCUS projects are able to move forward efficiently, from initial drilling to the long-term storage of CO2.
