S3 sets a new benchmark for European onshore and transition seismic in landmark CCS survey
Smart Seismic Solutions (S3) is deploying over 50,000 STRYDE nodes to deliver a major carbon capture and storage (CCS) exploration survey in Denmark for Harbour Energy, as part of the Greenstore project.
Greenstore is an onshore CO₂ storage initiative located between the cities of Randers and Hobro in central Denmark and is operated by Harbour Energy, with INEOS Energy and Nordsøfonden as partners. Over the coming years, the project will assess the potential to establish a full-scale onshore CO₂ storage facility across an area of approximately 500 km², with the ambition of becoming operational as early as 2030.
As part of this evaluation programme, S3 will conduct the largest and most complex seismic survey ever undertaken in Europe. The seismic data will underpin the selection and appraisal of potential storage sites ahead of drilling activities, which are planned to begin with the first exploration well in summer 2026, followed by two additional wells in 2027.
This project marks the third deployment of STRYDE’s nodal seismic system by S3 across its European new-energy portfolio, reinforcing S3’s confidence in STRYDE’s ability to deliver high-resolution subsurface data efficiently, safely, and cost-effectively.
For the upcoming 3D seismic survey, S3 will deploy 50,000 STRYDE Range+ nodes across 160,000 receiver locations. The high-density acquisition programme is designed to deliver a comprehensive seismic dataset capable of imaging potential subsurface CO₂ storage formations across the full 500 km² survey area between Randers and Hobro.
Vibroseis trucks will be used as the seismic energy source, with approximately 41,000 source points planned across the survey area.
STRYDE’s high-capacity nodal ecosystem will enable S3 to process over thousands of nodes per day, allowing for fast turnarounds and efficient redeployment into the field. The system’s scalability supports lean field operations with a small crew footprint, reducing operational costs, survey time, and logistical complexity.
Each STRYDE node weighs just 150 grams, making it the lightest autonomous seismic receiver on the market. This lightweight form factor allows small crews to deploy nodes entirely on foot, minimizing reliance on vehicles. As a result, the project is expected to significantly reduce HSE risks associated with driving and cut CO₂ emissions.
Patrick Robert, CEO of S3, commented: “We are proud to continue imaging Denmark subsurface between middle and northern Jutland targeting Bunter sandstone. Having completed two highly successful projects with STRYDE, we’ve experienced how their scalable system optimizes our seismic field operations. It enables faster, leaner campaigns that deliver requested data quality on budget and with significantly reduced land impact - key factors for our new energy clients.”
Amie Foster, Business Development Manager of STRYDE, added: “We are thrilled to continue supporting S3 as they push the boundaries of modern and sustainable exploration. Their repeat investment in STRYDE’s technology reflects the growing recognition that high-quality seismic doesn’t have to come with high cost or high carbon impact. Together, we’re proving that it’s possible to accelerate the energy transition through smarter, more efficient seismic acquisition.”
