Carbon dioxide capture and storage (CCS) is an emerging technology that could help to
reduce global emissions of this greenhouse gas to the atmosphere. The techniques used to
plan, engineer and monitor CCS schemes are similar to those used in the hydrocarbons
industry. This meeting provides an opportunity to learn about new initiatives in this exciting
field that could be very important to the UK economy and help reduce CO2 emissions
worldwide.

In countries which rely heavily on coal to generate electricity, carbon capture and storage
(CCS) could be a vital technology to allow them to continue to grow, but also to cut their
CO2 emissions. This is the main reason why CCS has such a high political profile. In Britain
the Government predicts that CCS could be an industry the size of present day North Sea
oil. According to 2006 figures, rocks under the UK North Sea could store about 22 billion
tonnes of CO2 which is 180 years production of CO2 from the UK’s 20 largest point sources
(e.g. power stations). The British
Government also thinks that the
CCS business could be huge:
estimates suggest a value of £2-4
billion per year by 2030, sustaining
between 30,000 and 60,000 jobs.
Other circum North Sea countries
are also becoming aware of the
value of their subsea pore space.
Further afield, in the Gulf Coast of
the United States where CCS is
close to being commercially viable
because of the value of CO2 to the
enhanced oil recovery business, the
U.S. Geological Survey is advertising
Texas pore space as the ‘CO2 sink for the USA’. Basins with high potential for CCS need
to be surveyed and in many areas geological surveys are leading, for example the BGS and
TNO in the southern North Sea, the Bureau of Economic Geology in the Texas Gulf Coast,
and Geoscience Victoria in the Gippsland Basin, Australia. Accurate storage estimation is
needed, as well as integrated regional basinwide modelling to handle multiple use of pore
space, for example oil and gas production, natural gas storage and water extraction. A
problem that is perhaps not considered enough is public acceptance. The science of CCS
needs to be well communicated to the public and to government, and independent
scientific organisations like geological surveys and universities have a special role. A broad
approach should ensure that the public sees the opportunity of CCS as just that - a way to
develop and sustain climate abatement and energy in the national interest.

CARBON DIOXIDE STORAGE: AN INTRODUCTION

Carbon Capture and Storage

THE CARBON DIOXIDE STORAGE PROJECT AT SLEIPNER
IN THE NORTH SEA: TIME-LAPSE MONITORING RESULTS
Andy Chadwick, British Geological Survey
The Sleipner project in the Norwegian North Sea is the world’s longest running CO2
storage operation. Injection commenced in 1996 and has now stored around 12 million
tonnes of CO2 in the Utsira Sand, a large saline aquifer some 900 m beneath the seabed.
Storage site monitoring is a key element in demonstrating storage integrity and Sleipner
provides an excellent example of this in action. The injection operation is being intensively
monitored with a number of geophysical tools including seismic, gravimetric and electromag-
netic methods. In the fourteen years since the start of injection 3D seismic surveys have been
repeated roughly every two years in a comprehensive time-lapse monitoring programme.
The seismic data provide dramatic images of the progressive development and growth of the
CO2 plume in the storage aquifer (Figure 1). They also provide assurance that none of
the CO2 is migrating upwards through the overburden towards the seabed. A crucial
aspect of monitoring is to demonstrate that predictive models of site performance can be
calibrated and verified. At Sleipner, detailed comparison and history-matching of the seismic
images with reservoir flow simulations of plume development demonstrate that the injection
project is proceeding according to plan, with no evidence of leakage from the storage
formation. Ongoing CCS research at BGS is using the Sleipner example to develop suitable
monitoring systems to address the recently developed regulatory requirements for
underground storage.

CARBON DIOXIDE CAPTURE AND UTILISATION
Mercedes Maroto-valer, National Centre for Carbon Capture and
Storage and University of Nottingham
Carbon dioxide capture and storage (CCS) technologies aim to capture CO2 from major
point sources, e.g. power plants, for subsequent transportation and ultimately storage in
geological formations. This presentation will review the main technologies to capture CO2,
including post-combustion, pre-combustion and oxyfuel. However, the use of current
state-of-the-art flue gas CO2 capture technologies in existing coal-fired power plants would
result in an average reduction of efficiency of about 33% and would reduce net plant power
output by approximately 1/3. Therefore, the development of high-capacity, low-cost CO2
sorbents will also be discussed.
The second part of the presentation will describe routes for the utilisation of CO2 as this is
an important CCS strategy to ensure the permanent, safe storage of CO2. One of the
most advanced routes for CO2 conversion is mineralization, where CO2 is reacted with
oxides and silicates to form carbonates that are stable over geological times, as these
processes mimic the naturally occurring weathering of rocks to form stable carbonates.
Finally, this presentation will also look into recent developments and opportunities to
develop nanotechnologies for CO2 utilisation (ar tificial photosynthesis), including
nanostructured materials for photoconversion and photoreactor design.
3D MODELLING IN CCS
John Williams, British Geological Survey
Carbon capture and storage (CCS) may prove to be an important technology in order
to assist the UK in cutting its CO2 emissions. Current predictions estimate that the CO2
storage capacity of the UK continental shelf (UKCS) is in excess of 22 billion tonnes in the
North Sea alone, while a CCS industry in the UK could sustain a vast number of jobs.
Because of this, the British Geological Survey (BGS) has been undertaking 3D modelling in
order to gain a greater understanding of the pore space relevant to CCS in the UKCS.
3D modelling can aid our understanding of reservoir geometry, thickness, depth, structure
and internal property variation. How a potential CO2 reservoir relates to its sealing
formations is important, as is its potential connectivity with other sub-surface operations
such as hydrocarbon fields, natural gas storage and potable water aquifers. The distribution,
geometry and properties of faults and other fracture networks are also important in

3D MODELLING IN CCS
John Williams, British Geological Survey
characterising a particular formation or region for CO2 storage. 3D models can assist
geoscientists to assess how much of a reservoir’s pore volume is in fact exploitable for
storage, and can provide a platform for calculating the practical storage capacities and
constraining factors.
Along with outcrop data and published information, models are built using subsurface data
acquired by the hydrocarbon industry such as well and seismic data. Both 2D and 3D
seismic data are available from industry, and interpretations of these data are often
incorporated into models.
In the Southern North Sea and East Irish Sea, static 3D reservoir models of saline aquifers
and depleted hydrocarbon fields are being constructed in order to map the subsurface, and
it is hoped that dynamic simulation of these models will vastly improve our ability to
determine suitable storage sites for CCS. Simulation of CO2 injection will predict the
transport routes that CO2 will take within the storage formation, and will also provide
information on the evolving pressure distribution resulting from injection. Injectivity of
the storage formation can therefore be assessed, as can the fate of the CO2 over various
timescales.

The model describes the relationship between the Triassic sandstone formations and the thick sealing strata across the basin - the reservoir outcrops to surface and sea bed at the basin margins and at several other localities within the model area.

I was very pleased to see the continued popularity and
convivial atmosphere of the Leeds meeting New
Advances in Palaeontology and Palaeoclimatology, held
at Weetwood Hall. We have jointly met with friends
from Leeds Geological Association for many years and
this continues to be a very successful arrangement.
The meeting organisers try to provide a variety of topics
and we enjoyed four excellent talks covering the latest
research on climatic changes during the Devonian and
Tertiary. Our next meeting in Keyworth is on a closely
related and topical theme about advances to manage the
harmful effects of carbon dioxide emissions by looking
at carbon capture. A further new benefit for Society
Members is available from Northern Geological Supplies
who are now offering significant discounts on their stock of geological equipment.
For many years the Society has benefited from storage of back issues of the Proceedingsand other printed materials at York Museum. Alterations to the buildings have meant that
this facility is no longer available. Council decided that these should be removed and
temporarily stored in Leeds for sorting pending a decision about possible re-housing. The
search for a General Secretary goes on and it was agreed by Council that enquiries should
now be commenced to evaluate the use of bought in secretarial services.
You will have received in the last Circular more details of the 2011 Programme. As we
move away from the winter months I am looking forward to the field season which opens
in May with Yorkshire Geology Month. Last year the Society’s web pages and Circularcontained details of all the events that take place throughout the County and the same
arrangements are planned for this year. The Society’s contribution is an excursion to the
Sedgwick Trail near Dent led by John Knight, which promises to be an interesting and
no doubt popular day. If you are running any local events for Yorkshire Geology Month
please let us know and we can include details on the web pages.
This field excursion aimed to examine the history and the landscapes of the Ironstone
Industry in North Yorkshire. The exploitation of the geological raw materials of North
Yorkshire created an area of rapid economic growth and industrialisation during the 19th
century. The Cleveland ironstone industry saw the peak of production between 1875 to
around 1898. The field excursion aimed to investigate the Jurassic geological foundations of
the industry and the social and landscape transformation that took place as a result.

GOING UNDERGROUND
A group of 12 YGS members met in the windswept car park of Skinningrove Ironstone
Mining Museum [471170, 519225], just north of the former mining town of Loftus (Locality
1, Figure 1). The Museum’s guides showcased some of the best documented history of
North Yorkshire ironstone mining and set the scene for a day’s exploration of its industrial
legacy and geological foundation.
After a short video telling the story of the discovery of the rich ironstone seams, the group
were treated to a visit underground. In the cool, dark adit the group experienced a little of
the life of the miners and their daily routine underground. After lighting a fuse and loading the
trucks full of ore the group emerged at the surface and travelled to the first surface locality.

BACK TO THE SURfACE
The Railway Cutting at Spawood (Slapwith)
[463300, 515780] exposes sections in part
of the Cleveland Ironstone Formation
(Locality 2, Figure 1). Together with the
underlying Staithes Sandstone Formation, it
forms part of Yorkshire’s ‘Middle Lias’
sequence. With the exception of the Eston
Hills area, this area represents one the thick-
est developments of the ironstone seams,
with the Main Seam reaching thicknesses up
to 2.5 m. After lunch and in the shelter of the
cutting, the group examined the marine
ooidal, bethierine (chamosite) ironstone and
surrounding sideritic mudstone of the Pecten
Seam (Figures 2 and 3). The Pecten Seam,
here, is approximately 0.7 m thick and
contains abundant coarse-ribbed bivalves and
brachiopods. The Main Seam was worked
extensively in the nearby Spawood, Spa and
Slapwith mines between 1853 and 1906.
A combination of drifts and shafts were used
to work the Main Seam, which in the area
of Slapwath was approximately 86m below
ground level. An examination of the sequence
about 2 m below the Pecten Seam, on
the opposite side of the cutting, identified
an additional thin partly oolitic ironstone
seam that some members suggested may
belong to the Two Foot Seam.
After discussing the possibility of an exposure
of even lower seams next to the road below
the railway cutting, the group travelled west
towards Hutton Village [460215, 513690],
(Localities 3 and 4, Figure 1). Examination
of historical mine plans (Figure 4) and identi-
fication of former miner’s cottages in the

village, revealed the presence of a number
of disused mines in the Hutton area. The
Hutton Mines were a cluster of smaller mines
exploiting the Main and Pecten seams using
quarrying and drift methods. Mining of this
area was undertaken in 1852, one of the
earliest operations in the area. This was, in
part, a result of the arrival of the railway
from Middlesbrough to Guisborough (built,
incidentally, by the mine owner). The mining
in this area of the district was short lived
and production ended in 1865. Walking up
the hill from Hutton Village, the group
passed through mudstones and siltstones of the Redcar Mudstone Formation and the
Staithes Sandstone Formation before reaching seams of the Cleveland Ironstone Formation.
The lowermost exposed seam was interpreted to be the Raisdale Seam. Walking towards
High Cliff Nab, overlying seams and their shelly fossils of the Two Foot and Pecten were
examined.
Many interesting discussions took place throughout the day reflecting the close association of
the Cleveland Ironstone sequence and the industry that it once supported. We would
particularly like to thank Andy Howard and Dennis Goldring for providing expert perspec-
tives on the Cleveland Ironstone Formation and its history. The Tees Valley RIGS group is
also thanked for the resources provided on its website. After a vote of thanks by Martin
Whyte the day concluded at 16:00 in the bright sunshine of Hutton Village.
