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

Enough information
to put together a
storage plan?
Not yet!
Need appraisal well
42/25d-3
DECC awarded UK’s first
CCS appraisal well licence
in Nov 2012
Drilled/tested Jun/Jul 2013

“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
