Twelve Months Ago …

Discussed work to date in characterising 5/42

After several years of screening work, identified massive

saline aquifer in Bunter Sandstone of UK SNS

Seismic, two well penetrations plus surrounding wells

Since then

Have drilled & tested UK’s first dedicated CCS appraisal

well, 42/25d-3 funded by EEPR & ETI

Aim here is to discuss these developments

“The goal of the characterization

of the storage site and complex

is to assess the site’s capacity,

injectivity, hydrodynamics, containment

and monitorability in order to ensure

safe and permanent storage of CO2”

Conclusions

Regional studies show saline aquifers are very suitable

for large scale CCS

5/42 is big, close to emitters & has right properties

Data analysed to date from 42/25d-3 appraisal well

appears to confirm & enhance initial thinking

Continue to analyse data as it becomes available and

work with pipeline and facilities teams to refine design

Prepare FDP

Develop Technical MMV Plan
