1 Natural Gas Facts & Figures Section 1: Production and Reserves September 2014

2 1. Production and reserves Sources : Total G&P, WOC1, IEA, Ihs Cera, Resources- Reserves Conventional Unconventional : types and reserves Countries, companies Costs of production New technics and advances (undersalt, high depth, distant offshore) Environmental issues (as a specific part)

3 Natural Gas reserves: plenty & more to come Proven conventional reserves are growing In addition: Unconventional gas has come within technological & economic reach Conventional Unconventional Coal bed methane Shale gas Tight gas 3 Volume The total long-term recoverable conventional gas resource base is more than 400 tcm, another 400 tcm is estimated for unconventionals: only 66 tcm has already been produced. - IEA-Golden Age of Gas 2011-

4 tcm Conventional Reserves: plenty and more to come Growing proven reserves Europe Latin America North America Africa Asia-Pacific E. Europe/Eurasia Middle East Global proven gas reserves have more than doubled since 1980, reaching 190 trillion cubic metres at the beginning of 2010 Source: IEA World Energy Outlook

25 Unconventional resources

26 26 Types of Unconventional Gas Tight Gas Shale Gas Coalbed Methane Occurs in tight sandstone Low porosity = Little pore space between the rock grains Low permeability = gas does not move easily through the rock Natural gas trapped between layers of shale Low porosity & ultralow permeability Production via triggered fractures Natural gas in coal (organic material converted to methane) Permeability low Production via natural fractures ( cleats ) in coal Recovery rates low Source: Shell

27 Types of Unconventional Gas Tight Gas : Natural gas produced from reservoir rocks with such low permeability ( 0.1md) that massive hydraulic fracturing is necessary to produce the well at economic rates. The gas is sourced outside the reservoir and migrates into the reservoir over geological time. Shale Gas : Natural gas produced from ultra-low permeability ( md) formations that may also be the source rock for other gas reservoirs. Coal Bed Methane (CBM) : Gas associated and produced from coal beds, its composition is predominately methane, but can also include other constituents, such as ethane, carbon dioxide, nitrogen and hydrogen Gas Hydrates : Also called methane hydrate, methane clathrate, or natural gas hydrate Gas hydrate is an ice-like crystalline solid consisting of gas molecules (usually methane, but also ethane, carbon dioxide, etc.) each surrounded by a cage of water molecules (clathrate).

36 New technics and developments Brazilian Pre-Salt Heterogeneous carbonate reservoirs, with highly variable petrophysical properties. Pre-Salt fields mostly located at water depths exceeding 2,000m. Reservoirs depths at 5,000 to 6,000 meters below sea level. Natural gas associated with oil, in a gas-oil ratio between 200 and 300 m 3 /m 3 Variable contents of CO2, ranging from 8 to 12% under an extensive salt layer (up to 2,000 meters in some areas)

37 New technics and developments Arctic Shelf in Russia Special physical hurdles lots of ice, extremely low temperatures, remote locations and long periods of darkness Challenges : Geographic Location Deep Water Large fields Ultra long distance

38 New technics and developments Example : Shtokman Location of Shtokman field Shtokman gas and condensate field pre-development scheme

39 Technical challenges Deep gas (below 4500m) and ultra-deep gas (below 7500m) Some examples Russia : structure of Achimov of the Urengoy fields China : Dina2 gas field in the Tarim basin Azerbaidjan : Shaz Deniz II Australia : Martell, Noblige and Larsen HP/HT Sour gas (H2S and CO2) Some examples US Norphlet play China Puguang field, with H2S at 15% Tunisia Hasdrubal plant
