Another example of an injection project that ended up badly is a waste-water injection project in the Tordis field (Norway). The operator had quickly investigated what went wrong, and why, and how to avoid that in the future. However, environmental organizations used the incident to question the safety of storing CO2 in the subsurface. This was especially relevant to the Sleipner project, where CO2 is injected into the Utsira sands - the same reservoir into which the Tordis waste-water disposal was intended to occur.
In the Tordis Field (Norwegian sector, North Sea) oily water was injected for disposal into a shallow aquifer thought to be the Utsira Sands, a well-known, good-quality reservoir. However, a miscorrelation incorrectly identified the intended storage reservoir. It was not the Utsira, which was later determined to be absent due to a pinch-out. Instead, the water was injected into a sand lens within the overlying Nordland Group (denoted by a star at the Tordis well location in the Figure below). Because this lens had a limited volume, reservoir pressure increased rapidly during injection and the seal was breached resulting in fluid escape and the leakage of oily water upward to the seafloor. This leakage created a crater 30-40 meters across and 7 meters deep on the seabed. In the wake of this, because the Utsira Sands are the CO2 storage reservoir at the Sleipner carbon storage project, environmental organizations began questioning the security of storing CO2 in the Utsira Sands. Not only does this case study illustrate how we can misinterpret the target injection reservoir and its potential impacts, but it also demonstrates how the failure of one project can implicate others.

Here is the latest in our blog series on CCS risk and uncertainty. THe link to the whole set is included. The next chapter will be posted tomorrow, Tuesday. Understanding issues that have occurred is a good way to anticipate and mitigate risks in a new project.

Accurate geological chronostratigraphic correlation is a key to the success of CCS and CCUS. With so much at stake for CCS projects, the risks and consequences of a miscorrelation are huge. #CCS #netzero #geology #chronostratigraphy #biostratigraphy #timecorrelation

Reservoir geometry, continuity, integrity should be properly studied before carbon storage to avoid complication as elaborated in the case below.

Are you or a loved one interested in a cutting-edge dredging method to clear cohesive sediments from your waterway or basin that doesn't require handling or storage? Are you a dredging nerd in general? Are you reading this? If you answered 'yes' to any question, then we have the research article for you! Excited to announce the team of myself, Joe Wagner PE BCNE BCEE, and my HDR colleague Robert Lewis had our paper published in the Transportation Research Record: Journal of the Transportation Research Board. Our article explores the current state of water injection dredging – an innovative technique that provides a regional sediment management approach for maritime authorities. Learn how this method is transforming waterways across the U.S. Read more here: https://lnkd.in/gn6pXQZA #Transportation #Dredging
