PERSPECTIVES

10

● Switch from Coal to Gas is a significant driver to

reduce GHG emissions.

● This switch will result in fewer constraints for CCS

development due to CO2 potential storage capacity

limits or costs.

● Gas CCS demonstrators and R&D are needed.

● CO2 Storage Capacity estimations are key to the

assessment of the development potential of CCS.

Gas Week 2014

“Reducing emissions with natural gas and Carbon Capture and Storage”

Lamberto Eldering Statoil

The Sleipner CCS project

20 November 2014

Outline – Key questions

• What have we learned about CCS operations and long-term CO2 storage at

Sleipner?

18 years of successful CO2 storage site operations

2014-11-12 13 Classification: Internal

• Sleipner gas fields

• Amine capture

from natural gas

• 0.9 Mtpa stored

• 15Mt stored by end 2014

• Injection started in Sept. 1996

• CO2 is injected in the Utsira Fm at ~ 900 m

depth (above the condensate reservoir)

• Operated by Statoil with licence partners

ExxonMobil and Total

• Since April 2014 CO2 from Gudrun field gas

(north of Sleipner) is also injected

9% CO2 in

the gas from

Sleipner Vest

15 Mt CO2

injected since

1996

Sleipner overview


Main achievements

• 18 years of successful CO2 storage site

operations

• Used globally as a role model for CCS

• Significant contribution to Norway’s emissions

reductions

• Important learnings for science and

technology of CO2 capture, transport and

storage

• Used to pioneer and demonstrate a range of

monitoring technologies:

− Time-lapse seismic

− Gravity monitoring

− Seabed mapping


Main challenges and barriers

• Project permitted under Norwegian Petroleum law

• During the project other conventions came into play

− OSPAR

− EU CCS Directive

• External interest leads to additional expectations on

the operator – data sharing and technical clarifications

• Geophysical monitoring data has led to significant

improvements in understanding CO2 flow behaviour

and storage capacity

• Gained experience on how much monitoring data is

needed for CO2 storage sites in general


EU CCS Directive

• Implementation of the Directive in Norway may

impose additional requirements beyond todays

practise.

− Possible technical implications

• Increased requirements on future

monitoring plan

− Liabilities

• Long term liabilities after injection stop

• Financial security for leakage risk

Main lessons learned

• Geophysical monitoring has proven essential for site management

Safe CO2 storage confirmed

• Monitoring of pressures is as important as saturation:

Down-hole gauges are highly desirable

• Practical learnings about capacity and injectivity from well

operations experience

• Monitoring the overburden is as important as the reservoir:

External interest may require analysis of regional and near-

surface datasets

• Time-lapse seismic imaging of CO2 plume development gives

much improved understanding of flow processes

Builds confidence in model forecasts

• Well defined governmental framework and regulations have

contributed to the stable and predictable operation


Test Center Mongstad (TCM)

• Capture technologies ready for implementation

• Measure technologies developed at TCM bridged

knowledge- gap on amine emissions

• Unique centre available for further testing
