1. Session 4: Oil statistics United Nations Statistics Division International Workshop on Energy Statistics 24-26 September 2012, Beijing, China

2. Total primary energy production

3. Shares of total primary energy production

4. Outline Classification Measurement units Statistical units Data items Current UNSD Questionnaire Common problems

5. SIEC 4: Oil 41 Conventional Crude Oil 42 Natural Gas Liquids (NGL) 43 Refinery feedstocks 44 Additive and Oxygenates 45 Other Hydrocarbons 46 Oil Products 461 Refinery Gas 462 Ethane 463 Liquefied Petroleum Gases (LPG) 464 Naphtha

6. 465 Gasolines 4651 Aviation Gasoline 4652 Motor Gasoline 4653 Gasoline-type jet fuel 466 Kerosenes 4661 Kerosene-type Jet fuel 4662 Other Kerosene 467 Gas Oil/Diesel Oil and Heavy Gas Oil 4671 Gas Oil/Diesel Oil 4672 Heavy Gas Oil 468 Fuel Oil

7. 469 Other Oil Products 4691 White spirit and special boiling point industrial spirits 4692 Lubricants 4693 Paraffin waxes 4694 Petroleum coke 4695 Bitumen 4699 Other oil products n.e.c.

8. Measurement units Liquid fuels can be measured in Mass (e.g. Tons) and Volume units (e.g. Barrels) Conversion between Mass and Volume done through the specific gravity or density While IRES does not give recommendations for units to be used for national data collection, it recommends that Liquid fuels are disseminated in Metric Tons IRES recommends that countries collect data in original units and data on specific calorific values

9. Measurement units IRES recommends the use of net calorific values (NCV) when expressing the energy content of energy products rather than gross calorific values (GCV) However, where available, countries are strongly encouraged to report both gross and net calorific values IRES 4.36

10. Statistical units IRES recommends the use of establishments and households as statistical units for energy statistics For example, for energy industries: Oil and gas extraction (ISIC 06 – Extraction of crude petroleum and natural gas) Oil refineries (ISIC 19 – Manufacture of coke and refined petroleum) and others…

11. Data items They reflect data collected from statistical units

13. UNSD Annual Questionnaire

17. Common problems Data on calorific values are often not reported Refinery input vs refinery output Refinery capacity often not reported International bunkers vs domestic transport Gross refinery output Input into electricity and heat generation versus electricity and heat produced Energy use vs non-energy use
