Petroleum production reporting system• Data collected to allow DECC engineers to
monitor operation of UK oil and gas fields– field level – mainly for engineers– terminal level – mainly for statistics
• Companies obliged to report monthly – part of licence agreement

EU-ETS data
Gas for electricity generation
Survey of main power producers• Used as input for other fuels – so not specifically a gas
survey (70 forms on monthly basis, 32 of which have gas data)
Survey of auto-producers• Again survey of all fuels – (100 forms on a quarterly basis, 75
report gas)• Heat production data also obtained
Secondary survey data• Questions on electricity generation also asked on quarterly
gas survey (used for verification)
Energy Industry Use
Most data from PPRS admin system re gas use in oil and gas extraction
From survey of oil refineries
Data from Iron & Steel Statistics Bureau for use in blast furnaces (monthly)
Data from National Grid re losses
Final consumption
• Survey of main gas suppliers – quarterly for headline data, annual for detailed breakdown – 23 firms account for 95% of gas sales – semi compulsory with new EU legislation
• Survey of small gas companies – annual with request for likely sales in coming year – 70 firms - voluntary 25% response
