3. CO2 Storage
● Finding Geological Storage
● Accessing the Storage Formation
● Monitoring Injection & Storage
Schlumberger Public
● A Real Example
● Summary
5. Finding the right Storage Site
What do we need?
Other:
Injectivity: • Environment
The ease with • Infrastructure
Schlumberger Public
which the CO2 • Regulation
can be injected • Public opinion
• Finance
Capacity: Containment:
The amount of The ability to
CO2 that can store CO2
be safely safely and
stored permanently
…the best risk reduction approach is to choose the right site in the first place
8. Storage Options
Stored in geological formations:
● Depleted oil or gas fields
Depth:
● Deep saline formations
1,500 – 3,000m
Schlumberger Public
5,000 – 10,000ft
TWO KEY POINTS:
Storage sites are NOT huge caverns…
…but „solid rocks‟ like a sponge.
Secondary
CO2 is NOT a gas, at depth, seals
but like a dense liquid.
Primary
seals
„Enhanced Oil Recovery‟ is NOT the same as storage. Storage
reservoir
9. Storage mechanisms & containment
Storage sites evolve over time...
● Structural & stratigraphic trapping
● Residual – in pore space
Schlumberger Public
● Solubility – in water
● Mineralisation – “turned to stone”
Oil & gas fields demonstrate
storage times of millions of years.
Natural accumulations of CO2 have
been safely stored for millions of years.
from IPCC, 2005
10. North Sea offers storage options for UK & Europe
North Sea has an abundance of
depleted oil & gas reservoirs and
deep saline formations.
Schlumberger Public
● Should we go for many small
stores or a few large ones ?
● Which ones should they be ?
● Studies for pipeline networks
(need to know where to go!)

13. CO2 Enhanced Oil Recovery versus Storage
Enhanced Oil Recovery Storage
● CO2 rate depends on ● CO2 rate determined by source
production strategy (eg. power station)
● CO2 recycled ● CO2 in long-term storage
Schlumberger Public
● Legislation under ● Legislation under new CO2 regime
petroleum industry (high public awareness)
● Operational Monitoring only ● Long-term monitoring
● Revenue from hydrocarbon ● Revenue from price of carbon
(eventually – current projects
government subsidized)
Significant experience in CO2 pipelines and
injection wells gained from US EOR
activities in the last 30+ years.

16. Wellbore Integrity – the challenge
Not just a „hole in the ground‟
―a complex hydro-mechanical system designed to fulfil many requirements:
• Shape: really strange (2km long, 20cm wide → 10,000 : 1 aspect ratio)
Schlumberger Public
● Connects the surface to storage formation
● Holds the borehole open
● Long-lasting
● Unaffected by CO2
● Materials – steel, cement, elastomers, fluids
● Barriers for fluid flow
● Economical – cost effective
● Repairable
● Geologically compatible
● Environmentally acceptable
● Retirement strategy – „plug and abandon‟

20. Possible leakage paths across a single cemented annulus
What can go wrong?
● no isolating material where required Contaminated
Injection
tubing
― (wrong volumes)
Schlumberger Public
cement
― losses during placement Casing
● incomplete isolating material coverage Vertical
― “mud channel” fracture
● improper bond with formation Pipe
― “mud removal” debonding
● improper bond with tubular Formation Mud
debonding
― “micro-annulus” channels
● isolating material not performing
― contamination during placement
― mechanical failure during well life
21. Mitigation of leakage through wells
A full well design based on risk assessment
● Position of well components
● Definition of overlaps
Schlumberger Public
● Where to use each cement system /
completion materials

as much as possible
● Robust construction practices required

44. CO2 Storage - Summary
● Finding Geological Storage
― Capacity, Injectivity, Containment + non-technical aspects
― Depleted reservoir, or saline formation ?
― CCS not the same as CO2 EOR
Schlumberger Public
● Accessing the Storage Formation
― A well is not just a “hole in the ground”
― Consider existing wells and new ones
― Quality of execution is essential over and above good design and materials
● Monitoring Injection & Storage
― Monitoring is critical part of storage design
― Large number of technology options – not all applicable everywhere
― Requirement to monitor for many years after injection ceases
● A Real Example
― Illinois Basin – Decatur Project
― 4 years from funding decision to injection
― In operation NOW.
