EAST SIBERIA RUSSIA

Field and Structures Atlas - Volume 1

EAST SIBERIAIntroduction

This Atlas is a description of the fields, discoveries and the most promising prospects identified to date in the Republic of Sakha (Yakutia), southern East Siberia. All the fields, discoveries and prospects presented in this volume of the Atlas are all confined to the Pribaykalskiy Petroleum Basin.

Hydrocarbon Reserves

At the end of 2009, hydrocarbon reserves of the Republic of Sakha (Yakutia) amounted to: 1302.7 Bm3 (46 Tcf) and 1208.9 Bm3 (42.7 Tcf) of C1 and C2 natural gas reserves, respectively; 248.0 Mt (1.9 Bbbl) of C1 (recoverable) oil developed and 188.1 Mt (1.4 Bbbl) of C2 (recoverable) oil preliminarily estimated. If the current rate of local consumption (approximately 1650 Mm3 (58 Bcf) of gas and 0.2 Mt of oil per year (1.5 Mbbl) remains the same, the gas will last 1500 years and the oil, more than 2000 years.

Structural map example

The total С1 + С2 gas reserves in the subsurface of the areas in Yakutia and Irkutsk Oblast in the immediate proximity to the route of the East Siberia – Pacific Ocean (ESPO) pipeline amount to as much as 113,385 Bm3 (4000 Tcf).

The south of the Siberian Platform may very well prove to be rich in hydrocarbons, as within its limits occur vast hydrocarbon kitchens associated with paleorift systems, various types of reservoirs, seals and traps and local anticlinal structures in the platform’s sedimentary cover. Therefore, the hydrocarbon reserves proven to this date are believed to be great enough to enable implementation of large-scale oil and gas production and transportation projects. See map for the fields and prospects described in this Atlas.

EAST SIBERIAThe East Siberia Pacific Ocean Pipeline System (ESPO) The ESPO is being laid to connect the oil producing fields in West and East Siberia to the sea ports in Russia’s Primorskiy Kray and thus, to enable Russia to ship its oil to markets in the USA and the Asia-Pacific Region. The planned total length of the ESPO Pipeline is 4188 km. The pipeline is to be operated by Russia’s state-owned Transneft company.

The ESPO pipeline “will unlock significant oil reserves in East Siberia and the eastern flank of the West Siberian Basin” (Sobornov et al., 2007). “It is also believed that East Siberia has the potential to become one of the main hydrocarbon production centres of the eastern Russia and Asian-Pacific regions and that closer to year 2025 a delivery of East Siberia oil should completely replace the West Siberia oil supply” (Varlamov et al., 2007).

Well log example

Volume 1 of the Atlas will provide information focused on Yakutia:

1. Regional geological setting

2. Stratigraphy

3. Volume estimates, directly sited from field and prospects reports which give characteristics such as:

� Whether reserves are recoverable or geographically present

� Volumes of hydrocarbon in metric units split into hydrocarbon type

� Reservoir characteristics where available:

� Trap type

� Hydrocarbon column height

� OWC

� GWC

� Net Pay

� Average porosity

� Average permeability

� Graphical representations displayed

4. License information/ exploration history (where available):

� Date of discovery

� Discovery well

� Other wells in the area

� Key formations

� Production rates

� Current licensees

The Atlas will be available in hardcopy and PDF format.

The following will be available as digital enclosures to the Atlas:

� Seismic data (SEGY)

� Well log data (LAS)

� Maps (Arc GIS)

East Siberia Field Atlas OverviewThe East Siberia Fields/Prospects Atlas is a systemised compilation of information and data over approximately 100 fields/prospects in the Irkutsk/Yakutia provinces of East Siberia, located in the vicinity of the ESPO pipeline.
