1. INTRODUCTION
By John Gallagher, Vice President Technical – Europe, Shell Exploration & Production Europe
I am pleased to introduce this Environmental Statement,
covering Shell U.K. Limited’s Exploration and Production
(EP) activities during 2007.
The purpose of this report is to explain our environmental
performance and work programmes in 2007 in the UK, and
to update our plans for improvement in 2008/9. The report
is updated annually.
In Section 2 you can see a map of our activities. In the UK
sector of the North Sea we operate 35 platforms, 3 Floating
Production Storage & Offloading (FPSO) vessels, and 18
subsea installations; in total we have interests in 61 fields (52
operated) and three onshore gas plants. Our European EP
operations, and in turn the UK assets, are an important part
of our global portfolio, and will remain so for years to come.
We operate more production in Europe than any other
International Oil Company (more than twice the second largest
IOC). We are also one of the largest investors, averaging over
$5 billion per year in Europe in the last five years and for the
next five years and we have been and we will continue to be
an industry leader in frontier technology developments.
We are particularly pleased that, at the end of 2007, our
Environmental Management System (EMS) was certified to
ISO14001. This demonstrates that we have a systematic
approach to managing our environmental risks that meets
international standards. In 2008 we are continuing to work
on improving our EMS.
Our environmental objectives reflect our key challenges – to
work with others and to provide our own contribution towards
addressing climate change, to continue to reduce emissions,
discharges and wastes from our locations and to ensure our
operations in sensitive areas take account of the expectations
of all stakeholders.
Our performance shows that this is being achieved in some
areas. There are also areas for improvement that we will act
upon.
Looking to the future, our business will continue to change.
We will move forward with adjustments to our asset portfolio
and address new challenges such as decommissioning. Our
main target areas for performance improvement are currently
in the areas of greenhouse gas (GHG) and energy management,
continuing to reduce the risk from oil and chemical discharges
and improving our environmental impact assessment processes.
These will be delivered by focusing on legal requirements and
Shell Group standards and through enhancements to our EMS.
I hope you will agree our commitment to improving
environmental performance is demonstrated throughout this
report.

2. WHAT WE DO
2.1 OUR E&P ACTIVITIES AND OPERATIONS
Our Environmental Management System covers all of our
UK activities and locations that are used in the exploration,
production and processing of hydrocarbons.
Our business is divided up into organisational units called
Assets and Functions. Assets are typically groupings of four
to six locations supported by onshore teams, and cover all
our physical facilities including offshore fields, installations
and associated wells, the onshore gas plants, and all associated
pipelines. All our UK facilities can be viewed on the UK
Map in Section 2.2. Functions typically manage the support

activities required by the Assets such as engineering and
maintenance services, development planning, project planning
and execution, survey work, organizing support vessels and
helicopters, laboratory services, drilling wells and the
management of our offices.
Detailed descriptions of EP activities and operations are
provided on the shell.com website.

3. ENVIRONMENTAL MANAGEMENT IN SHELL EXPLORATION &
PRODUCTION EUROPE
3.1 OUR ENVIRONMENTAL MANAGEMENT SYSTEM (EMS)
Figure 2 - Environmental Management System
Shell Exploration & Production Europe’s Corporate
Management System (CMS) documents the way in which the
company conducts its business. The Environmental
Management System (EMS) is an integral part of the CMS.
It consists of the elements shown in Figure 2 above.
‘Policy and Strategic Objectives’ contains our HSE Policy
and the Strategic Environmental Objectives. The HSE Policy
(see Section 3.2) contains a commitment to protect the
environment and states that we have a systematic approach
to HSE management designed to ensure compliance with the
law and to achieve continuous performance improvement.
‘Organisation, Responsibilities, Resources, Competency’
describes the organisational structure and the roles and
responsibilities that deliver environmental management. The
competency of personnel carrying out roles within the EMS
are addressed and the resources necessary to ensure that the
EMS is in place and maintained. Communication processes
around environmental issues both within and outside of Shell
are detailed.
‘Risk Management’ covers the identification of environmental
aspects and legal and other requirements that relate to our
environmental aspects. It also contains the operational
framework for managing significant environmental aspects.
‘Environmental aspects’ are those elements of our activities
that can interact with the environment (see Section 3.3).

‘Processes, Assets and Standards’ describes the processes
that are undertaken to support our assets and the relevant
standards. Processes and standards contain environmental
information to ensure that the EMS is effectively implemented
in the assets.
‘Planning’ contains our Health, Safety and Environmental
(HSE) Plans, which contain objectives, targets and improvement
programmes. In preparing our HSE Plans, we take into account
our environmental aspects and legal and other requirements.
This enables us to implement our HSE Policy commitments
to achieve continuous performance improvement and ensure
compliance with the law.
‘Implementation (reporting and monitoring)’ covers the
monitoring of activities that can have a significant environmental
impact and monitoring of environmental performance. This
section also covers the periodic evaluation of compliance with
legal and other requirements.
‘Assurance’ covers the internal audit process by which we
check that the EMS continues to be effectively implemented.
Management reviews are also conducted annually to ensure
the EMS is effective and delivering improvements.

3.3 The Environmental Aspects of our Operations
Environmental aspects are elements of our activities, products
or services that can interact with the environment. Figure
3 illustrates the main environmental aspects we have identified
for our offshore locations. We have grouped our significant
environmental aspects into four areas:
• Atmospheric emissions
• Energy use
• Discharges to water including spills
• Waste
3.3.1 Atmospheric Emissions
We burn natural gas and sometimes diesel as fuel on our
facilities to generate the power that is required to run our
operations. In addition, our facilities are designed to ‘flare’
(burn) and ‘vent’ (release unignited) a certain amount of
hydrocarbon gas for safety reasons. Most locations have a
continuous stream of gas to flare or vent designed to stop
the ingress of air into the facilities that could cause explosive
mixtures in the process. Additional amounts are also released
through this route during installation shutdown, when all
hydrocarbon gas systems are depressurised and when certain
equipment items are out of service (either planned or
unplanned).
The majority of our emissions to air are the products of
these combustion processes. The emissions include carbondioxide,
nitrogen oxides, sulphur dioxide, carbon monoxide,
unburnt hydrocarbons and particulates. These atmospheric
pollutants have global (climate change), regional (acidification)
and local (air quality) effects.
3.3.2 Energy Use
In addition to atmospheric emissions, consumption of diesel
and gas to provide energy is an important issue from the
point of view of depletion of natural resources. We are
currently developing GHG and Energy Management Plans
for each of our major installations.
3.3.3 Discharges to water
Most of our discharges to water consist of surplus water
from our oil and gas wells. This "produced water" is a mixture
of naturally occurring water in the reservoir, and seawater
that has been injected into the reservoir to support the
pressure and sweep oil towards the production wells. We
separate the produced water from the oil and gas, and discharge
most of it into the sea. The separated water contains a small
amount of residual oil as well as chemicals both naturally
occurring such as salts, and others such as corrosion inhibitors
and de-oilers.
As well as produced water, many of our wells produce sand
and scale which accumulates in pipework and vessels and
needs to be cleaned out from time to time. When pipework
and vessels are cleaned, the sand and scale is also cleaned to
remove as much oil as possible before it is discharged.
Produced sand contains similar materials to produced water
and may also contain small amounts of Naturally Occurring
Radioactive Material (NORM) which may occur naturally in
an oil or gas reservoir. All discharges are monitored and
recorded.
We also use seawater for cleaning purposes. After use any
‘wash water’ is cleaned before being discharged back into the
sea via specially designed drains. Legally permitted levels of
cleaning chemicals and some oil may remain in the water
when it is discharged. Other drains on our installations
discharge surface water, such as accumulated rainwater or
seawater, which do not normally contain any oil or chemicals,
as well as emergency fire-fighting water and foam, directly
into the sea.
Finally the smallest contribution to our discharges to the sea
comes from leaks and spills from our wells and equipment.
Such spills may consist of oil, gas, chemicals, or a mixture of
the three. Continuous monitoring, adherence to procedures
and rehearsal of emergency response keeps these unintended
discharges to a minimum.
3.3.4 Waste
A variety of solid and liquid wastes are produced from both
our on and offshore operations including drilling waste such
as cuttings and spent muds; wastes such as oily rags, fluorescent
tubes and batteries, and also office and packaging wastes such
as paper, card and wood.
Some wastes can be treated and re-injected into reservoirs
e.g. drill cuttings under the appropriate legal licences. However
the majority of wastes are shipped to shore for onshore
disposal. All waste, irrespective of where it is produced, is
transferred to licensed facilities for either treatment and
disposal; or sorting and bulking prior to transportation for
final disposal.
All waste is transported and disposed of in accordance with
our European waste management policy, in particular through
application of the waste hierarchy to prevent and reduce
waste as far as possible and minimise the volume of waste
to landfill.

4. ENVIRONMENTAL PERFORMANCE
4.1 Our Environmental Goals, Objectives and Targets
Shell Exploration and Production in Europe maintains
environmental management systems that are certified to
the ISO14001 standard and we strive for continuous
environmental improvement through the following strategic
objectives, covering our significant environmental aspects
(Section 3.3):
• Reduce discharges to sea and emissions to air through
continuous improvement, operational excellence
and deployment of technological step changes.
• Manage use of energy and resources and minimize
the generation of waste.
• Work with others to maintain ecosystems and
minimise interference with biodiversity and
vulnerable areas.
• Optimise the potential for lateral learning from cooperation
with external environmental stakeholders
Improvement programmes to deliver the above cover legal
compliance and the fourteen elements of the Shell Group
Global Environmental Standards (GES).
Each objective is translated into key targets (where relevant)
and improvement programmes year on year to drive
continuous improvement across our UK operations. The
current targets, performance and improvement plans for
each objective are summarised in the sections below. More
environmental data for 2004-2007 are provided in
Appendix 1.

4.2 Reduce Emissions and Discharges
Our first objective drives our requirement to improve the
way we conduct our activities by focusing on reducing key
emissions and discharges.
4.2.1 Greenhouse Gas Management
Burning fuel gas and diesel, flaring and venting are our main
sources of GHG emissions, although there are also
contributions from transportation and office energy use.
We support the Shell Group’s publicly committed voluntary
target to have CO2 emissions in 2010 5% below the 1990
level. Annual GHG targets are established for our European
activities and these are translated into targets for each of
our assets.
Figure 4 shows the mass of GHG emitted from each of the
main sources on each of our major platforms and onshore
plants during 2007. In 2007 we emitted 3.51 million tonnes
of GHG from our UK operations and activities.
Approximately 78% of the GHG emissions came from
combustion and 22% from flaring and venting. After taking
into account the effect of portfolio changes (we sold Auk
and Fulmar fields in November 2006), GHG emissions were
2.1% lower than in 2006.
In 2007, we flared 230,000 tonnes of hydrocarbon gas. This
is significantly lower than the 272,000 tonnes flared in 2006

(2006 figures corrected for portfolio changes). Reductions
were seen on most installations, Cormorant Alpha being the
only installation flaring significantly more than in 2006. This
rise was due to a failure of the main compressor bundle
which resulted in flaring of associated gas for several weeks
During 2007 we operated under Phase 1 of the mandatory
EU Emissions Trading Scheme for CO2 (EU ETS). It
should be noted that in 2008 the EU ETS will be expanded
to Phase 2 which will include CO2 from flaring. Work is in
progress to upgrade flare monitoring and reporting to achieve
the higher accuracies needed for EU ETS.
There are programmes underway in the business aimed at
future reductions in GHG from our facilities, including:
• Increased focus on operational flaring. Following our
adoption of the new Shell Global Environmental
Standards, we have enhanced our controls on operational
flaring.
• Implementation of recommendations made by energy
efficiency assessments made as part of PPC permit
applications. In 2008, we plan to implement 16 different
projects.

4.2.2 Oil in Produced Water
An annual oil in produced water target is established for our
European activities and is translated into targets for each of
our assets. These discharges are subject to the
recommendations under the OSPAR Convention implemented
in the UK through The Offshore Petroleum Activities (Oil
Pollution Prevention and Control) Regulations 2006 and also
our own Shell Group Environmental Standards. In 2001
OSPAR set a goal to ensure that the total quantity of oil in
produced water discharged into the sea in the year 2006 from
all offshore installations within the jurisdiction of each OSPAR
member country should be reduced by a minimum of 15%
compared to the equivalent discharge in the year 2000. In
2007 our installations discharged 868 tonnes of oil in produced
water to sea compared with 1,800 tonnes in 2000, a reduction

The chart below shows the actual amount of oil discharged
to sea by each of our installations compared to our targets.
Most of our installations discharged below our targets and
the total oil to sea was well within our overall company target
for 2007. However, the Dunlin platform went over target
owing to less than expected performance of the chemical deoiler
and low production volumes passing through the separate
Osprey/Merlin process which reduces separation of oil.
Nelson missed its target because the Produced Water Re-
Injection (PWRI) system was not working to its full capacity.

Figure 6 shows the actual volume of produced water discharged
to sea by each of our installations and the average measured
concentration of oil dispersed within it. On three installations;
Sean, Shearwater and Solepit Clipper, although the volume
of discharge is small, the concentration of oil in produced
water is well above 30 mg/l.
The Sean field is a swing gas producer and started-up
production for only two months at the end of 2007, the
average OIW concentration was 159 mg/l.
On Shearwater there has been a decrease in OIPW overboard

quality in 2007 due to excess sand production and bringing
on line production from satellite fields which cools down the
production process and hence impairs the oil water separation
process. In 2008, we will continue to search for a solution.
On Solepit Clipper, despite installing two centrifuges in 2005
at a cost of some £1.9 million, the problem persists particularly
during periods of less water throughput. Therefore we are
now planning to install PWRI surface facilities in 2008 and
then prepare a well and commence produced water re-injection
into a subsurface reservoir in 2009.

4.2.3 Accidental spills
All loss of containment (whether it reaches the sea or is
contained and recovered on the location) is reported through
our incident reporting system and subject to assessment and
incident investigation depending on the risk posed to the
environment. See Appendix 2 for more details of reportable
spills.
Analysis of our spills shows an increase from an average of
around 10 significant spills (oil, gas & chemicals > 100 kg)
over recent years to 20 in 2007. The causes of these spills

fall into three main categories: equipment failure, human
error and corrosion. We have instigated a programme to
review these spills in order to understand the root causes
better.
For 2008 onwards, an annual target for significant oil spills
(>100 kg) of 24 tonnes has been established for our European
activities. Because of their variable nature, this is not translated
into targets for each of our assets.

4.2.4 Chemical Management
Our use and discharge of chemicals in production and drilling
operations is subject to The Offshore Chemicals Regulations
2002 (OCR) and our own Shell Group Standards. The historic
trend in production chemical discharge is relatively stable.
This is the result of two counteracting trends where our
efforts to switch to better chemicals and reduce treatment
concentrations are balanced by greater consumption due to
increasing water production.

Production chemical use and discharge varies amongst our
installations. Those in the Southern North Sea (Clipper,
Leman, Sean) use relatively little because they are predominantly
gas processing facilities; whereas our Northern North Sea
installations use more owing to factors like reservoir chemistry,
water cut and high produced and injected water volumes. As
can be seen from the chart, we predominantly use low
risk/hazard products, but some platforms use a higher level
of SUBs mainly corrosion inhibitors that are highly effective
but carry substitution warnings. We are committed to phasing
out these chemicals. Our substitution programme is delivering
an overall decline in the use of SUBs, but the numbers fluctuate
as a result of the re-classifying of products when new rules
are applied to the screening process by CEFAS, or when new
data is submitted to CEFAS by the chemical vendors.

Figure 7 shows the total weight of chemicals discharged to
sea by each of our installations. Discharges have been grouped
into two categories, with the green colour representing the
'low risk/hazard' groups and the red depicting the 'more
hazardous/higher risk' groups. Overlying this is a line that
represents ‘SUB’s – chemicals which have been flagged with
a Substitution Warning by the Centre for Environment,
Fisheries and Aquaculture Science (CEFAS).

4.3 Use of Energy, Resource and Waste Minimisation
4.3.1 Energy Use and Resource Management
The efficient use of energy and the minimisation of upset
flaring is an integral part of our operational excellence
philosophy to minimise the waste from our operations and
conserve valuable natural resource. They also represent the
main areas of improvement with regard to reducing our
emissions of GHG as described in Section 4.2.1 above.
Energy use is mainly from power generation on our locations
where we burn fuel gas or diesel to run pumps, compressors,
engines, heaters and general platform services. We also report
on electrical energy purchased onto sites and offices. A
certain amount of flaring is a design feature at most of our
locations for safety reasons during steady operations, but
additional amounts of ‘process upset’ flaring occurs when
equipment fails or during planned shutdown of facilities for
maintenance work.
Although energy use has reduced, production rates have
dropped at a faster rate leading to an increase in energy
intensity over the last two years. Increasing energy intensity
is characteristic of maturing fields in the North Sea and is
caused by such factors as reducing reservoir pressures and
increasing water cuts of the wells. Improvement programmes
have already been described under 4.2.1 GHG Management.

Figure 8 - The Waste Hierarchy
4.3.2 Waste Minimisation
In order to move waste disposal up the waste hierarchy, we
work closely with our contractors to reduce the volume of
waste going to landfill. While our overall tonnage of waste
production increased by 10% from 2006 to 2007, the
proportion sent to landfill was reduced by 30%. This can be
attributed mainly to the success of a mud treatment process
developed by our waste contractors. Prior to this development,
waste drilling fluids were mixed with solids and land-filled,
thereby actually increasing the volume of waste to landfill.
The new process reduces the requirement for landfill to less
than 30% of the original volume.
During 2007, our assets were encouraged to segregate their
waste effectively, thereby ensuring legal compliance and
maximising recycling opportunities. A series of skip
segregation exercises were held throughout the year and the
results fed back to the assets to demonstrate areas for
improvement. Proven to be a very useful tool for raising
awareness, the number of these audits has been doubled in
2008.
Other smaller changes to reduce waste in the offices have
been introduced and similar initiatives are being developed
in 2008 which will encourage our staff awareness on waste
management and give further success in years to come.

4.4 BIodiversity and Vulnerable Areas
The Shell Group Biodiversity Policy and Commitment states
our commitment to work with others to maintain ecosystems
and respect protected areas through the application of
environmental impact assessment and development of
biodiversity action plans for operations in the areas of high
biodiversity value.
Two of our onshore facilities (Braefoot Bay Terminal and
Bacton Gas Plant) operate in close proximity to (though not
actually in) environmentally sensitive areas. In addition, several
of our offshore installations and pipelines are located in the
areas of potentially sensitive marine habitats. These sensitive
sites and locations are recognised internally as “High
Biodiversity Value Areas” according to the Shell Group
Standards. We support these areas through membership of
local forums and consultation with relevant national agencies.
Using the Environmental Impact Assessment process, we
apply appropriate controls for plants and installations and
projects that have the potential to impact on these areas.
4.5 Monitoring Seabed Impacts
Environmental seabed surveys are one way to monitor the
impacts of our activities. Contaminants enter the marine
environment through discharge of cuttings, muds, produced
water, and even deposition from the atmosphere. Seabed
sediments provide a sink for these contaminants. Sediment
quality and diversity of seabed plants and creatures are good
indicators of impacts and recovery. It is important for us
to have scientific evidence to evaluate our impacts, especially
around older installations and those in proposed conservation
areas. In 2007 we developed a long term seabed monitoring
programme. Using a risk-based approach, several sites were
selected for three and six year monitoring. The programme
was reviewed and supported by BERR and JNCC. We started
in 2007 with surveys around Brent and Gannet fields. Leman
and Clipper fields are scheduled for surveying in 2008.
4.6 Lateral Learning and Cooperation
We believe in being involved in the environmental agenda in
the local areas where we operate and in addressing wider
regional and global concerns where we have a role to play.
To this end, we participate in various stakeholder, government
and industry fora and provide resources and expertise in key
areas to help define our role in environmental protection.
In addition, we jointly fund research and technology
Paguridae (hermit crab) at Gannet D
Anemones at Indefatigable J
programmes in areas where more information or design work
is required to enable us to decide the best way forward. For
example, in 2007 we sponsored a Joint Industry study to
investigate a metric for the assessment of the behavioural
and audiological effects on underwater animals of man-made
underwater noise.

Scope: The figures shown above relate to all Shell operated offshore installations and 3rd Party fields that produce to them
plus onshore plants and mobile rigs in the UK – all as reported to EEMS. Some changes are due to asset divestment.
Global Warming Potential: The 2007 figure is lower than trend owing to divestments and several prolonged shutdowns.
In 2008, the figures will be affected by:
• Norwegian gas being piped to St Fergus
• Nelson PWRI load and improved reliability
• Further divestments
Production Chemicals: 2007 chemical use was relatively high due to a single once-off activity on the Dunlin platform where
15,000 tonnes of a foaming chemical was used to displace 'attic' oil from the seabed storage cells. In Figure 3 these are
coloured orange at the base of the platform. The cells are now decommissioned and filled with water. Before decommissioning,
the foaming chemical was used to displace oil downwards to the level of the withdrawal pipe within the cells. This single
activity accounts for the higher use and the drop in percentage discharge. Without it chemical use and discharge would be
very similar to 2006.

APPENDIX 2 - OIL AND CHEMICAL SPILLS AND OIL DISCHARGES
Notifiable (PON 1) Oil and Chemical Spills Number
Notifiable (PON 1) Oil and Chemical Spills Total Mass (tonnes)
Spill of Sodium Bicarbonate solution due to a loading hose failure on Dunlin when pumping from a supply
vessel.
Subsea leak of crude oil from Gannet C due to a weld failure while carrying out pigging operations.
Subsea leak of hydraulic fluid from Gannet D.
Subsea leak of hydraulic fluid from Pierce.
Spill of Monoethylene Glycol (MEG) on Goldeneye due to a pipe failure.
Failure of bellows on cooling medium system on Shearwater resulted in the cooling system leaking onto the
platform deck and then into the open drains system.
While filling the Caravel Monotower, there was a leak of bentonite (natural clay) gel from a bellows installed
around the gas export riser at the point where it exits the monotower a little above the seabed.
PON 1 = Petroleum Operations Notice No.1
We are required to notify the relevant authorities of all accidental/unplanned discharges or spills of oil or chemicals to sea,
regardless of volume, using a PON1 to:
• nearest Coastguard Station
• Department for Business, Enterprise and Regulatory Reform;
• Joint Nature Conservation Committee (JNCC)
• any relevant Statutory Nature Conservation Agency
The list of spills above shows only those greater than 2 tonnes.
