UK Production data – PPRS system

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

• Source of UK oil and gas production data, and some trade data

National grid / trade data Survey of electricity generators

Survey of auto-producers

Main gas surveyOther gas surveysOther dataEU-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 obtainedSecondary 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
