Unclassified -<br />
Environmental Management System Annual Public Statement 2011<br />
<strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> operated the Anglia Not Permanently Attended Installation (NPAI) in Block<br />
48/19b up to December 2010. Anglia is located approximately 70 km to the north-east of the<br />
North Norfolk coastline and approximately 80 km from the <strong>UK</strong>/Netherlands trans-boundary line.<br />
The Anglia field has eight production wells: six platform and two subsea tie-back wells. Natural gas<br />
is processed at ConocoPhillips’ LOGGS offshore complex. Anglia was divested in December 2010,<br />
therefore no further information will be provided concerning operations at this location.<br />
2.2.2 CYGNUS<br />
2.2.3 MINKE<br />
2.2.4 JULIET<br />
The Cygnus field is located in United Kingdom Continental Shelf (<strong>UK</strong>CS) Blocks 44/11a and<br />
44/12a of the SNS, approximately 159km north-east of the North Norfolk (<strong>UK</strong>) coastline and<br />
40km west of the <strong>UK</strong>/Netherlands median line [1]. The field is within the Dogger Bank candidate<br />
Special Area of Conservation (cSAC). The boundaries of the cSAC lie 40km to the east and 22km to<br />
the south. The cSAC has been designated as it is shallow sandbank that is covered by seawater all<br />
the time. As such it supports a diverse community of marine species including harbour porpoise,<br />
common and grey seals [2].<br />
<strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> actively works with other operators and stakeholders to ensure the<br />
environmental sensitivities of the area are understood and the environmental management<br />
programme undertaken reflects best industry practice.<br />
No operational work has been undertaken in the Cygnus field by <strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> during 2011,<br />
however an Environmental Statement was submitted to the DECC in September 2011 and a DECC<br />
letter of No Environmental Objections was issued on 5th March 2012 (DECC reference<br />
D/4119/2011).<br />
Two environmental surveys were conducted at Cygnus in 2011, which together ran for 57 days and<br />
consumed 343.91 tonnes of diesel.<br />
Minke is a subsea development tied back to the D15-A platform in the Netherlands, operated by<br />
<strong>GDF</strong> <strong>SUEZ</strong> E&P Nederland B.V. The Minke field is located 175km from the <strong>UK</strong> coastline and<br />
extends across the <strong>UK</strong>/Netherlands median line into the Dutch Block D15. Production started in<br />
2007 and gas is exported to Uithuizen in the Netherlands via the NGT pipeline system. There was<br />
no production or related activity associated with Minke during 2011 as the field has been shut in<br />
since December 2010.<br />
The Juliet field is located in Blocks 47/14b of the SNS, approximately 37km north east of<br />
Theddlethorpe. An environmental statement for this field development was submitted on 21 st<br />
February 2012 and a DECC letter of No Environmental Objections was issued on 1 st May 2012<br />
(DECC reference D/4136/2012). Development-related activities have not yet commenced.<br />
There has been one environmental survey at Juliet in 2011, which together ran for 3 days and<br />
consumed 48.70 tonnes of diesel.<br />
2.2.5 FARADAY<br />
2.2.6 JACQUI<br />
The Faraday field is located is located in block 30/1 of the Central North Sea (CNS). Faraday was<br />
drilled to confirm the presence of natural gas. Drilling commenced in August 2011 and was<br />
completed in January 2012. These 9 days in January are included in this report.<br />
Jacqui field is located in block 30/13b of the CNS, approximately 275km from Scotland. Jacqui - a<br />
high pressure / high temperature well - was commenced in January 2012 and is due for<br />
completion by the end of June 2012. This data will be included in the 2012 public statement.<br />
Two environmental surveys were conducted at Jacqui in 2011, which together ran for 5 days and<br />
consumed 31.48 tonnes of diesel.<br />

3.0 INTEGRATED MANAGEMENT SYSTEM<br />
3.1 HSE MANAGEMENT SYSTEM<br />
Unclassified -<br />
Environmental Management System Annual Public Statement 2011<br />
<strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> maintained ISO 14001 certification for its HSE Management System in both<br />
London and Aberdeen offices in 2011. The latter applies to all our offshore operated assets and is<br />
designed to reduce the impact of our activities on the environment through careful planning,<br />
defined roles and responsibilities, appropriate plans and procedures, robust monitoring and<br />
reporting systems and continuous review of performance. By adopting and implementing the<br />
system, we also ensure there is an ongoing process for environmental risk identification,<br />
assessment, mitigation and control throughout the project lifecycle.<br />
Our Health, Safety and Environment Management System (HSEMS) is an integral part of our<br />
Company’s Business Management System. The environmental arrangements help us to evaluate<br />
our impact on the environment, and prioritise and control our significant environmental aspects.<br />
The HSEMS is structured to manage compliance with environmental legislation, to prevent<br />
pollution and to drive continuous improvement of our environmental performance. It also ensures<br />
we take a systematic approach to the way we manage our environmental impacts. Our work ethics<br />
are based on a principle of continuous improvement, namely:<br />
Setting clear business objectives to deliver success<br />
Taking time to plan, and agree roles and responsibilities<br />
Implementing the right systems and processes to achieve those objectives efficiently,<br />
consistently and cost effectively<br />
Measuring performance and using it to drive continuous improvement.<br />
3.2 HSE GOALS AND POLICY<br />
<strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong>’s goals are:<br />
Zero injuries<br />

4.0 DRIVING ENVIRONMENTAL PERFORMANCE<br />
Unclassified -<br />
Environmental Management System Annual Public Statement 2011<br />
Finding and producing oil and gas inevitably has an impact on the environment, resulting from<br />
both onshore and offshore activities, which we strive to control with an effective EMS. Aspects of<br />
our activities that can interact with the environment include:<br />
Atmospheric emissions (e.g. from diesel combustion in generators, gas flaring)<br />
Energy consumption<br />
Waste production (e.g. hazardous waste, conventional waste, drill cuttings)<br />
Chemical consumption and discharge<br />
Spills (chemicals, potentially diesel during bunkering)<br />
Fish disturbance from seismic activity<br />
4.1 ENVIRONMENTAL INDICATORS<br />
Table 1 shows our performance against a suite of environmental indicators for the years 2008 to<br />
2011.<br />
None of the fields listed in Section 2.2 was in production during the period covered by this report.<br />
Consequently there is no reported production this year.<br />
However, <strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> had drilling activity at two wells in 2011. As noted previously, the<br />
Faraday well was completed in 2011 and the associated environmental indicators are shown in<br />
Table 1. Drilling activity at Jacqui continues into 2012 and performance indicators are not yet<br />
available. These will be included in the 2012 annual report.<br />
The data in Table 1 have been extracted from the EEMS reporting database [3]. Conversion factors<br />
in EEMS are used to derive atmospheric emissions from fuel usage. Chemical and waste<br />
consumption data is collected on a regular basis from offshore contractors. Means of data<br />
reporting is audited on a regular basis. An overview of <strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong>’s performance on these<br />
aspects is presented in Sections 4.1 to 4.5.<br />

4.2 ATMOSPHERIC EMISSIONS<br />
Unclassified -<br />
Environmental Management System Annual Public Statement 2011<br />
<strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong>’s atmospheric emissions during 2011 were primarily generated from fuel (e.g.<br />
diesel) burnt for offshore power generation during our drilling activities, along with emissions<br />
generated from vessels during environmental survey operations.<br />
Table 1 gives emissions figures for the various gases emitted during our offshore operations since<br />
2008. There has been an increase in emissions since 2010; however they were not as high as<br />
those of 2009. These changes are related to the number of wells being drilled during the period<br />
considered. Figure 4 and 5 shows the variations in Global Warming Potential (GWP) and<br />
Acidification Potential (AP) from 2008 to 2011.<br />
The GWP of emissions is expressed in tonnes of CO2 equivalent, based on a given time horizon of<br />
100 years [4]. This is calculated by multiplying the quantities of each contributing component of an<br />
emission by an individual conversion factor [5]. In the case of hydrocarbon combustion the<br />
contributing components are CO2, CH4 and N2O with conversion factors of 1, 21 and 310<br />
respectively. No other gases which contribute to global warming were reported as emitted as a<br />
result of <strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> operations during 2011.<br />
AP of emissions is expressed in tonnes of SO2 equivalent. This is calculated by multiplying each<br />
contributing component of an emission by an individual conversion factor [6]. In the case of<br />
hydrocarbon combustion the contributing gases are SO2 and NOx, with conversion factors of 1 and<br />
0.7 respectively.<br />
The data indicate that there has been an increase in emissions contributing to GWP since 2010,<br />
but an overall fall since 2009. Emissions contributing to AP have not shown the same fall since<br />
2009, this is because proportionately less gas is now burnt (which causes lower acidification<br />
potential than diesel use).<br />

4.3 ENERGY USE<br />
Unclassified -<br />
Environmental Management System Annual Public Statement 2011<br />
Our energy use is primarily for power generation and is directly linked with the level of activity. For<br />
drilling activity and survey operation, diesel is the dominant source of fuel, as is reflected in the<br />
data shown in Figure 6.<br />

In this report, the term ‘recycling’ covers waste reused, recycled or converted to energy. The term<br />
‘landfill’ covers waste going to landfill for disposal or types of disposal other than through recycling.<br />
Figure 7 and figure 8 illustrate the total amount of waste produced and recycled between 2008<br />
and 2011, including conventional waste, hazardous waste and waste from drill cuttings.<br />
The amount of hazardous and conventional waste produced is largely dependent on the extent<br />
and nature of activity, which during 2010 and 2011 predominantly relates to drilling operations. All<br />
waste quantities have increased since 2010. For hazardous waste, tank washings containing oil<br />
based mud are the largest proportion of this stream. In 2011 tank washing represented 997.5 out<br />
of 1004.3 tonnes of hazardous waste, which compares with 575.4 out 614.2 in 2010.<br />
Drill cuttings represent the highest proportion of the total waste produced across all years, with<br />
overall quantities again being mainly a reflection of drilling activity. Year on year comparisons have<br />
limited value due the variability of well dimensions and cuttings generated. Cuttings are generated<br />
from the borehole while drilling the wells and are brought back to the surface by the drilling mud.<br />
The cuttings associated with water-based muds are normally discharged to sea. Those associated<br />
with oil-based muds (and consequently contaminated with base oil) are recycled during operations<br />
and then shipped to shore. There they are treated to remove the majority of hydrocarbons, prior to<br />
disposal as landfill.<br />

4.5 CHEMICAL CONSUMPTION<br />
Unclassified -<br />
Environmental Management System Annual Public Statement 2011<br />
All offshore activities involving the use and/or discharge of chemicals are covered by the Offshore<br />
Chemicals Regulations (OCR) 2002 (as amended in 2011). A chemical permit must be obtained<br />
from the Department of Energy and Climate Change (DECC) to use and/or discharge chemicals<br />
offshore. See Table 1 – Environmental Performance Indicators.<br />
Chemicals used offshore are ranked according to the potential to cause environmental harm if<br />
discharged. Two methods of ranking are used, depending on the methodology used to assess the<br />
risk. In one chemicals are ranked by letter, from E to A, with E representing the least risk. In the<br />
second method the chemicals are ranked by colour as Gold, Silver, White, Blue, Orange and Purple<br />
in order of increasing hazard [7] . The majority of products ranked as E are comprised of components<br />
included on a list of chemicals which are considered to pose little or no risk (PLONOR) to the<br />
environment under the Oslo Paris (OSPAR) Convention. Table 2 shows chemicals used and<br />
discharged during <strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> offshore operations, during 2011, by ranking. PLONOR<br />
products made up 77% of the total use and 97% of the total discharge during the reporting period.<br />
Table 2 - 2011 Total chemical use and discharge, by ranking<br />
Ranking A B C D E Gold Silver Total 2011<br />

Discharge (%) 0 0 0 4.8 8.4 15.8 0 7.3<br />
In addition to the above ranking methods, the OSPAR convention requires the offshore industry to<br />
make efforts to remove from use chemicals which are highly persistent or combine at least two of<br />
moderate persistence, toxic and bioaccumulating, or contain substances, such as heavy metals or<br />
organo-halogens, which are considered to be particularly hazardous to the environment. These<br />
products are included in the list of candidates for substitution (SUB) maintained by the Centre for<br />
Environment Fisheries and Aquaculture Science (CEFAS). In order to conform to the Offshore<br />
Chemcial Regulations and to achieve continual improvement of our environmental performance<br />
<strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> endeavour to replace and/or minimise discharge of these products, unless<br />
continued use can be justified on technical or safety grounds. Table 3 shows the SUB chemical use<br />
and discharge during <strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> offshore operations during 2011.<br />

4.6 SPILLS (PON 1 RAISED)<br />
Unclassified -<br />
Environmental Management System Annual Public Statement 2011<br />
A reportable incident occurred during the drilling of Faraday (Block 30/1) on the 22nd September<br />
2011 from the drilling rig GSF Galaxy II. 394kg of an oil based drilling fluid (Versatherm) were<br />
released into the marine environment due to the failure of a hose seal on the drilling rig.<br />
Immediate steps were taken to isolate the hose and minimise the release. The spill appeared as a<br />
silvery sheen on the surface of the water and covered an area of approximately 350m 2 . As<br />
required under the conditions of the PON15B, this incident was reported to the DECC through the<br />
timely submission of a PON1 (PON1/652).<br />
4.7 LEAKS (GAS RELEASES)<br />

5.0 2011 INITIATIVES<br />
5.1 ISO 14001 CERTIFICATION<br />
Unclassified -<br />
Environmental Management System Annual Public Statement 2011<br />
The <strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong> HSE Management System (HSEMS) was recommended for continued<br />
certification to ISO 14001:2004 at both the London and Aberdeen offices. No major or minor nonconformities<br />
were identified during the most recent audit and no observations or improvement<br />
opportunities were noted. The next audit will be a renewal audit, which will involve a review of the<br />
Business Management System (BMS) against ISO 14001.<br />
The certification brings us many benefits, including:<br />
Independent assurance that the Company meets, and continues to meet our HSEMS<br />
commitments and policy requirements;<br />
Streamlining operations - greater operational efficiency and energy conservation, and reduction<br />
in the use of hazardous materials and generation of hazardous wastes;<br />
Increased awareness and participation from better communication about environmental issues<br />
inside and outside the organisation;<br />
<strong>GDF</strong> <strong>SUEZ</strong> E&P <strong>UK</strong>’s ISO 14001 programme raises the profile of environmental issues and<br />
makes it clear that environmental performance is an important part of our corporate culture;<br />
Safety benefits by regularly reviewing our HSEMS for ISO 14001 we are able to identify and<br />
implement health and safety improvements.<br />
5.2 OBJECTIVES AND TARGETS<br />
In addition to our Company’s objectives we have defined, in association with the other E&P<br />
affiliates, common Key Performance Indicators (KPIs) to assess our performance and offer<br />
benchmarking opportunities. 2011 performance results are very good, with all targets being met<br />
except one, showing an improvement on the 2010 results (Figure 8).<br />
