Carbon storage that lasts—for good

CO2 storage. Effective storage requires precise selection, planning, construction, operation, and monitoring of the sequestration site. Using the right experience, right know-how, and right technologies, SLB optimizes these storage phases to reduce your costs and risks.

SLB has more than 100 years of experience in mapping, measuring, and modeling underground rock formations. And we’ve participated in more than 100 sequestration projects in different geological contexts over the last two decades using innovative solutions. This experience gives us detailed insight into the varied challenges posed by CO2 storage. Integrating geoscience, engineering, and digital capabilities, we’re able to deliver a CO2 storage project anywhere in the world.

Improve time to FID

We use our industry-leading suite of modeling tools to progressively model the subsurface during site identification and appraisal. This results in reduced risk, a better understanding of project feasibility, and shorter timeline to final investment decision (FID).

Optimize planning, development, and injection

SLB solutions cover the full spectrum, from planning and site development to injection and monitoring. With a tailored suite of CO2 technologies, we help to reduce risk and provide assurance for long-term storage.

Understand long-term CO2 behavior

We’ve developed modeling tools to predict CO2 plume migration. Combined with our data acquisition technologies during and postinjection, this results in an accurate representation of injected CO2 volumes.

Site identification and feasibility

Selecting the right storage site early on is key. This will help avoid unnecessary costs associated with appraising unsuitable sites. We developed a range of methods for screening geological basins and comparing different sites. Within your area of interest, we collect the available data and select candidates for further evaluation.

The key criteria:

  • Capacity—How much CO2 can be effectively stored at the site? 
  • Containment—Does the storage site provide sufficient seal capacity to prevent CO2 leaks to surface? 
  • Injectivity—What injection rates can be achieved? 
Site appraisal

Site appraisal describes the many measurements and models needed to confirm the suitability of a site. This phase is essential to understand the geology and behavior in great detail. We

  • image the geological structure of the site from surface using seismic data or other technologies
  • drill wells and investigate the rock properties using logging tools and then evaluate rock and fluid samples in one of our labs
  • assess injectivity using fluid flow testing.
Planning, development, and injection

Together, we develop a specific plan for reliable storage. This includes the well location, construction techniques, and monitoring methods.

Injection wells are engineered with the durability to deliver the CO2 to the storage target and isolate and protect the intervening formations. Our well construction services ensure the quality and stability of wells crucial to long-term integrity. And using Optiq fiber-optic solutions, we can evaluate CO2 injection, containment, and well integrity; monitor CO2 behavior; and more. 

Before injection starts, we design and develop monitoring wells equipped with sensors. Baseline monitoring readings are then taken from the wells and surface systems. The injection phase typically lasts from 10 to 50 years, and throughout that time, we monitor the storage system to compare actual storage performance against predictions.

Three main types of monitoring are carried out:

  • Injection monitoring focuses on controlling and optimizing rates across the suite of injectors.
  • Verification monitoring tracks the CO2 underground and verifies the performance of the physical barriers that isolate the reservoir.
  • Assurance monitoring confirms the integrity of the near-surface environment, protecting valuable resources such as shallow drinking-water reserves.
Postinjection

CO2 storage is still an emerging technology. Regulation and best practices will evolve in the next decade. Whatever the requirements, at each site, the wells will need to be safely plugged for long-term integrity, the surface equipment removed, and appropriate monitoring continued. High confidence in long-term integrity will only be achieved by having a site that has been well chosen, well designed, well operated, and well monitored.

That’s what we do.

Our work in action

Enabled by our digital capabilities, technologies, and expertise, SLB was selected to use the DELFI cognitive E&P environment on the Norwegian CO2 project by the Northern Lights JV to streamline subsurface workflows and longer-term modeling and surveillance of CO2 storage. The JV was established to develop the world’s first open-source CO2 transport and storage infrastructure—accelerating decarbonization opportunities for European industries to store up to 5 million metric tons of CO2 per year based on market demand.
