HSE Performance

The lost time injury frequency includes the number of fatalities and lost workday cases per million exposure hours. Exposure hours are collected for Talisman employees, contractors and subcontractors using the guidelines provided by the International Association of Oil & Gas Producers (OGP) document Health and Safety Incident Reporting Systems Users' Guide Report No: 444. Exposure hours for North American operations are collected using the labour factors as percentages of capital or operating budgets described in the Canadian Association of Petroleum Producers (CAPP) Document 2008-1029 June 18, 2008 Reporting of Occupational Injuries. Lost time injury frequency reported within corporate responsibility reports prior to 2008 used a smaller subset of this definition and did not include all of Talisman global operations.

Production energy intensity is the amount of energy consumed at Talisman operated industrial facilities per barrel of oil equivalent (boe) production. Energy use includes gross energy consumption including energy generated on site or imported. Energy consumed by mobile sources, and in exploration and drilling operations is excluded. Boe production includes the gross amount of all saleable products from Talisman operated installations converted to an equivalent volume of oil on an energy equivalency basis. Saleable products include hydrocarbons, electricity and sulphur. Higher heating values are used to determine the energy content of fuels. Reported values are calculated using measured data and production based estimates.

Total CO₂e emissions are the gross direct and indirect atmospheric greenhouse gas releases from all sources at Talisman operated industrial facilities. Direct emissions source categories include on-site combustion, flaring, venting, and fugitive losses. Emissions resulting from initial assessment of well flow characteristics, i.e., well testing, are included in the scope of direct emissions. Emissions from mobile sources and drilling operations are excluded. Indirect emissions are a consequence of energy needs at Talisman operated industrial facilities, but occur at sources owned or controlled by another party (e.g., purchased electricity or steam). CO₂e emissions is a metric used to convert the mass of each greenhouse gas to a mass of CO₂ that would give the equivalent warming effect. The carbon dioxide equivalent for a gas is derived by multiplying its mass by its global warming potential (GWP) relative to CO₂. The GWPs from the IPPC (Intergovernmental Panel on Climate Change) second assessment report are applied; specifically, GWPCO₂ = 1, GWPCH₄ = 21, GWPN2O = 310. Reported values are calculated using measured data and production based estimates.

Values reported for Malaysia in 2010 are not comparable with previous years as Malaysia operation changed their diesel fuel tracking process in 2010 to align with the global definition, resulting in a reduction of SOx emissions versus prior years. This is a new performance indicator as of 2009.

Production carbon intensity is the mass of direct and indirect CO₂ equivalent emissions per unit of oil equivalent production. CO₂ equivalent emissions is a metric used to convert the mass of each greenhouse gas to a mass of CO₂ that would give the equivalent warming effect. The carbon dioxide equivalent for a gas is derived by multiplyits its mass by its Global Warming Potential (GWP) relative to CO₂. The GWPs from the IPPC (Intergovernmental Planel on Climate Change) second assessment report are applied; specifically, GWPCO₂ = 1, GWPCH₄ = 21, GWPN2O = 310.

Barrel of oil equivalent (boe)production includes the gross amount of all saleable products from Talisman operated installations converted to an equivalent volume of oil on an energy equivalaency basis. Saleable products include hydrocarbons, electricity and sulphur. Reported values are calculated using measured and production based data.

Flaring is the gross amount of gas and/or liquid combusted at a stack tip prior to release to atmosphere at Talisman operated installations. Reported values include volumes from the initial assessment of well flow characteristics (well testing).

The volume of spills is the aggregate volume associated with all unintended liquid discharges outside of secondary containment or other impermeable confinement where one half barrel or more reaches the environment. The values reported here represent the volume reaching the environment and have not been reduced by the quantity recovered. The volume of spills includes both hydrocarbon (e.g. crude oil, condensate, other unrefined petroleum products, diesel fuel, gasoline, and other refined petroleum products) and other (e.g. produced water, drilling fluids, chemicals, etc.) liquids. Spills from seismic activities, routine oil in water discharges in accordance with regional regulations, and oil in water exceedences are excluded, in addition to releases with no potential for environmental impact and releases with negligible environmental impact, chemical or physical. Values reported for 2010 are not comparable with previous years due to adjustement in definition and change in the threshold for reporting spills.

Quantity of hazardous waste disposed both onsite and offsite. Includes all waste that is defined as hazardous, toxic, dangerous, listed, priority, special, or some other similar term as defined by country, regulatory agency or authority. Does not include: drill cuttings; wastes associated with the remediation of historic contamination at active sites (wastes generated during spill response/clean-up are included); wastes generated from the remediation of inactive or abandoned properties; wastes associated with the construction of new Facilities upon green field sites (wastes from the replacement or upgrade of existing Facilities are included); wastes generated by Contractors during maintenance of their own equipment or any materials brought on site by the Contractor that is eventually disposed as surplus by the Contractor. This is a new performance indicator as of 2010. Only those countries which had the existing capability to report this metric did so. Further expansion to other countries for reporting this metric is expected in coming years.
