The demand for hydrocarbons will continue to increase for the foreseeable future and satisfying this demand in a safe and environmentally-responsible manner are key to our strategy and our social license to operate. We are committed to delivering environmental performance that meets or exceeds regulations in all our operations.
Minimising the environmental impacts of energy exploration and production is one of our industry’s most important challenges. The efforts we make are demonstrated through the targets we set for ourselves each year. We closely monitor all our operations against these targets, while our own Environmental Management System is verified on an annual basis by an independent third party.
This report provides an analysis of our 2013 performance and illustrates the company’s commitment to communicating in an honest, transparent and responsible manner.
The number of unintended releases to sea increased during 2013 when compared to 2012. While releases from our assets have had minor or no impact on the environment, we maintain a strong HSE reporting culture and each case is investigated to identify root causes then take future preventative actions. We are committed to making significant improvements in this area.
The last year saw a rise in the volume of chemicals used in drilling activities and a rise in the amount of hazardous waste produced. Both were related to an increase in drilling activity across the North Sea business areas.
A company level decrease in CO2 emissions was recorded, primarily due to extended shutdowns at some of our offshore installations, however an increase in CO2 emissions per 1,000 barrels of oil equivalent (BOE) was observed. During shutdowns, little or no fuel or flare gas is burned, however power generation continues to be required and this is achieved through the burning of diesel fuel.
Our performance in terms of the concentration of oil in produced water released to sea improved in 2013. While it is clearly not desirable to release any oil, industry regulators place strict limitations on both the concentration and quantity of oil discharged in order to protect the marine environment. At these low concentrations, oil quickly disperses and is broken down by weathering and marine microorganisms. The internationally agreed emission limit enforced by the UK regulator (DECC) is 30mg of oil per litre (average over one month). In 2013, the average discharge concentration for our company improved to 14.5mg/l. This was significantly below the legal performance standard and marginally less than the UK industry average of 14.6mg/l.

Oil&gasproductionOil reservoirs contain a mixture of oil, produced water, and natural gas. A primary purpose of an offshore production platform is to separate out the extracted ‘well fluids’ into these three separate components using separation vessels. Once the oil has been separated from the gas and water, it is pumped to shore via subsea pipelines; or, in the case of oil from the Ross and Blake fields, shipped to shore. The gas is dried and then compressed. Some of the gas, where possible, is used to generate power to run the process equipment and the remainder of the gas is exported via pipeline to the UK mainland (see Table 2), used for gas lift, or flared.
The proportion of oil, gas and water produced from reservoirs changes over time. Oil and gas production will decrease, and the volume of water will increase. The separated water, known as produced water, is treated to remove oil droplets prior to discharge to sea.
DrillingAs the fields mature and more information about the reser-voirs becomes available, more wells may be drilled or existing wells may be revisited. This can be done either from the platform, or with mobile drilling rigs. Geological information and production tests determine how many wells are needed to produce the oil and gas effectively.

MinimiseimpactandcontinuousimprovementOur environmental commitment, as outlined in our corporate HSE policy, is to minimise our impacts and always comply with the law or the company’s standards, whichever are higher. All environmental aspects including climate change, air quality, water quality and waste are issues that receive constant attention to minimise our environmental impacts. The environmental impacts from oil and gas exploration and production activities have been minimised as far as practicable through the design of the installations and subsequent modifications made to plant and process.
Wefollowa2-phaseenvironmentalmanagementstrategy.The first phase consists of the identification and characterisation of our environmental impacts to determine their significance and how to manage them. This considers local environmental sensitivities, company and legislative performance standards, and stakeholder concerns.
The second phase involves the development and implementation of environmental management strategies that are integrated with business and operational systems, and are in concert with all company performance improvement objectives: such as safety and installation integrity, and security of supply.
TargetsandobjectivesOur Senior Leadership Team set annual corporate and site-specific environmental targets. Each is set with a view to achieving the overarching objective of continuous improvement. To ensure all of our installations work towards achieving the targets, a performance contract is agreed with the site leadership team and company personnel.
Environmental performance is tracked using a set of performance indicators. Each site’s performance is monitored relative to its targets in areas such as Carbon Dioxide (CO2) emissions, oil in produced water, hazardous chemical use, spills and waste management.
PermitsandconsentsOur conduct in the North Sea is governed by a range of legislation and we are required to hold a number of permits and consents that authorise our operations. These permits and consents come with detailed operating conditions to which we must adhere.
We track and investigate non-compliances (permit breaches) to measure and continually improve the effectiveness of our systems, processes and procedures.
Figure1 – Our Corporate HSE Policy
HEALTH, SAFETY& ENVIRONMENT POLICYOur goal is to create a working environment such that we cause no harm to people, and where we minimise our impact on the environment.
To achieve this we will:
Always comply with the law, or Talisman Sinopec Energy UK standards, whichever is higher;
Operate our business to ensure proactive risk mitigation and continuous improvement;
Set goals and targets, and measure performance against them;
Hold ourselves and our contractors accountable to meet Talisman Sinopec Energy UK standards; and
Communicate openly with those who may be affected by our activities.
Safe operations in all company activities is a core value. If operational results and safety ever come into conflict, we all have a responsibility to choose safety over operational results and Talisman Sinopec Energy UK will support that choice.
SAFE OPERATIONS IN ALL COMPANY ACTIVITIES IS A CORE VALUE.

During normal operations an installation burns fuel gas and diesel for power generation and flares the gas it cannot use or export for safety reasons. The combustion of hydrocarbons results in the emission of CO2 and other greenhouse gases (ghg’s). The level to which ghg’s contribute to global warming depends on the type of gas, for example 1 tonne of methane (CH4) has an effect on the atmosphere equivalent to 25 tonnes of CO2.
In order to comprehensively asses the impact of our operations, ghg’s are combined and expressed as tonnes of CO2 equivalent. CO2e / 1000 BOE has also been used as an environmental measure of production efficiency.
Figure2 shows a company level decrease in CO2e emissions in 2013, primarily due to extended shutdowns at a number of installations. The observed increase in CO2e / 1000 BOE represents a reduction in production efficiency, also caused by extended shutdowns as the drop in production can’t be offset completely by an equivalent decrease in emissions. During shutdown periods little or no fuel and flare gas is combusted however a requirement for power generation still remains. This is met by burning diesel.
Figure3 shows the contribution of CO2e from each source over the last 2 years. In 2013 emissions from fuel gas and flare decreased while emissions from diesel increased, reflecting the greater number of shutdown days in 2013 compared to 2012.
The European Union Emissions Trading Scheme (EU ETS) is a cap and trade system for CO2 emissions arising from fuel combustion and flaring. Figure4 shows how each site performed against its Government allocated allowance or ‘cap’ in 2013. 2013 saw the start of Phase III of the EU ETS, an aspect of this phase was a reduction in the free Government allowances allocated to each site. In light of this a number of our sites exceeded their free allowances. In line with the requirements of the EU ETS, allowances were purchased through a designated mechanism so that these sites had sufficient allowances to account for their CO2 emissions.

While it is clearly not desirable to release any oil, industry regulators place strict limitations on both the concentration and quantity of oil discharged in order to protect the marine environment. At these low concentrations oil quickly disperses and is broken down by weathering and marine microorganisms.
The UK government through the “Offshore Inspectorate” of the Department of Energy and Climate Change (DECC) enforces a standard, internationally agreed emission limit value of 30mg of oil per litre (average over one month). Figure5 shows that the average discharge concentration in 2013 improved to 14.5mg/l. This is significantly below the legal performance standard and marginally less than the industry average of 14.6 (Oil and Gas UK 2012).
Figure6shows that the majority of our assets reduced the concentration of oil in produced water. In particular improvements in performance were seen at Montrose and Bleo Holm who reduced the concentrations of oil in their produced water by 34% and 51% respectively.
In 2013, the total amount of oil discharged was significantly less than previous years. This was due, in part, to the general improvement in discharge quality, but also influenced by extended shutdown periods on a number of assets particularly Piper B which accounted for over half the reduction. (see figure7).
Due to the nature of produced water, discharges can give rise to an oil sheen on the sea surface around the installation. On occasions, either due to poor plant performance or calm weather, sheens can extend some distance from the discharge point. Where these sheens become more significant than normal, we are required to notify DECC. Three such notifications were raised by our company during 2013.
Figures quoted relate to offshore operations only and exclude discharges from Flotta Terminal.

The use and discharge of production chemicals is heavily regulated by DECC through the approval of a Life Permit for each asset and regulatory limits are integrated into our operations. DECC regulates chemical use and discharge through the Offshore Chemicals Regulation (OCR) 2002 (as amended). These regulations implement the OSPAR Decision 2000/2 on a Harmonised Mandatory Control System (HMCS) for the Use and Reduction of the Discharge of Offshore Chemicals on the UK Continental Shelf.
The HMCS decision details requirements for the comprehensive testing, ranking, hazard assessment and risk management of chemicals and in addition the substitution of certain chemicals by less hazardous alternatives. The use and discharge of substitution chemicals is directly affected by two main factors; uptime of the individual assets and swap out of substitution chemicals for more efficient, less hazardous alternatives.
Figure8 shows a year on year reduction in the use and discharge of production chemicals. This trend is attributable to reduced production through full shutdown of one site for the whole of 2013, extended annual shutdowns on several sites and the indirect impact of the helicopter shortage during the year.
Some chemicals have a substitution warning meaning they contain a component that may present a hazard to the marine environment. An important part of the HMCS is the substitution of these harmful chemicals through a phase out approach.
Figure9 shows a decreasing trend in substitution chemical usage since 2009. This trend has been achieved through replacement of chemicals with less hazardous versions, removal of unused products from permits, reclassification of chemicals which gain or lose the substitution warning as new data becomes available and the impact of reduced production resulting in less chemicals being used.

During the course of 2013, we drilled 4 wells in the UKCS 3 development and 1 exploration well, by contrast no new wells were drilled in 2012. We have also conducted numerous well interventions to improve performance of the wells and several pipeline maintenance operations.
Figure11, shows a marked contrast in quantities of chemicals used and discharged when comparing Pipeline operations and Drilling activities. Drilling operations use large quantities of chemicals but only a small proportion are discharged to sea. Pipeline operations in contrast, by their nature, will discharge most chemicals through flushing but the quantities involved are low compared to well operations.
The reduction in the number of substitution chemicals used during drilling operations, including platform drilling, continued to be a key focal area during 2013. We are continuing to work closely with chemical vendors and the drilling contractors to replace a number of substitution chemical products with less hazardous alternatives.
Oil Base Mud (OBM) cuttings are treated onshore to recover valuable base oil which is then recycled. The amount of OBM cuttings to landfill is dependent on the complexity of the well drilled . We continue to trial the latest developments in drilling fluid technology to reduce the number of well sections that have to be drilled using OBM.

Spillpreventioniscoretohowweoperateandreceivesconstantattentionthroughoutthebusiness.Wefocusonpreventionbyensuringthatourpeopleareawareofspillrisksandarecompetentinperformingtheirtasks,assuringplantintegrity,andmaintainingadherencetooperationalprocedures.
In 2013, despite our continued focus on spill prevention, the number of spills reported to the regulator increased from 31 to 48. Total mass released also increased to 84.12 tonnes in 2013 compared to a 2012 total of 24.45 tonnes. The vast majority of this increase can be attributed to an incident on the Claymore which was recorded in October for a total release of 56.2 tonnes. This incident was associated with a legacy design issue, resulting in the incorrect routing of lube oil during oil changes on a gas compressor. As soon as the issue was identified TSEUK engaged with the regulator DECC, the quantity reported was calculated to include previous releases from this source since 2011 but as the PON1 was reported in 2013 the total release quantity has been recorded against the 2013 statistics. This incident accounted for approximately two thirds of the total mass released in the year. Our investigation into this incident provided valuable lessons that will help us prevent a similar event in the future.
In addition to the Claymore incident a number of other spills in 2013 were attributed to failings in site drainage systems. To address this all sites were asked to carry out a full review of their drain management processes with particular focus on risk assessment to ensure that appropriate levels of control are in place.
Spill prevention was a focus area for 2013 and will continue to be in 2014 at TSEUK sites. In light of the 2013 spill performance TSEUK has set a target to reduce spills to sea by 30% in 2014. The prevention of oil, gas and chemical leaks is the first Talisman Sinopec Golden Rule. The TSEUK Environment team works closely with colleagues both on and offshore as well as our contractors to ensure an integrated approach to environmental, safety and operational integrity management.

WasteManagementisakeytopicfortheenergyindustry.Weutilisematerialsthatwillgeneratewastewhichincludedrillcuttings,metals,wastechemicals,wasteoil,paper,glassandwood.Inlinewithourenvironmentalpolicy,weworktomoveourwastesupthewastehierarchy:
In order to drive improvements in waste disposal practices each site are set targets. If these targets are not being achieved, various methods for improvement are discussed. These include the provision of more waste bins to the assets or increasing waste segregation awareness among the workforce.
Figures13 shows an increase in total waste generated in 2013 when compared to 2012. This is largely due to the Clyde and the Sedco 711’s Waste Performance which have significantly increased for the year; this is due to drilling activities on these installations and consequent generation of Oil Base Mud cuttings which are brought onshore for treatment and disposal. These cuttings are treated to recover and recycle the oil based mud. The cleaned solids are then disposed of to landfill. The company works closely with its drilling contractors to minimise the amount of waste generated and sent to landfill during drilling activities.
Waste materials generated offshore are segregated by type and shipped to shore for re-use, recycling, or safe disposal by a licensed waste company in full compliance with UK Waste Legislation. We actively pursue ways of managing our waste streams up the waste hierarchy; this involves taking advantage of opportunities to reduce, reuse, recycle, recover energy, or responsibly dispose of waste.
As shown in Figures15, the amount of waste material sent to landfill increased in comparison to last year, this can be explained by the increase in drilling activities on the Clyde and Sedco 711 as described above.
Figure16 shows the 2013 waste disposal routes with 35% of waste being recycled and 4% of waste being reused for the year for the total waste generated by our operations. The percentage of waste recycled is in line with the industry average in 2013.
