2. Sakhalin Island
Russian: Сахали́н,
Japanese: 樺太
Location: North Pacific Ocean
between 45°50' and 54°24' N
between the Sea of Okhotsk to the
east the Sea of Japan to the west
north of the Japanese island of
Hokkaido
Population: 497,973 in 2010
Indigenous peoples are the Ainu,
Oroks and Nivkhs.
Sahaliyan, the word that has been
borrowed in the form of "Sakhalin",
means "black" in Manchu.
3. Oil and Gas fields in Sakhalin Island
The North Sakhalin Basin is active Tertiary margin
and Cenozoic fold belt
It contains one major TPS called North Sakhalin
Neogene,
Consists of Neogene shale, siliceous-shale source
rocks, Neogene sandstone, fractured siliceous-shale
reservoir rocks.
field-discovery history from 1923 to 1992
Six onshore fields from 1923 to 1935
Onshore drilling in 1947 and in the 1960s
Offshore fields in the 1970s
Offshore jointly with Japan from 1976 to 1982
Six largest fields discovered after 1975
All existing offshores in depths of less than 100 m.
72% offshore, 28% onshore
within latitude 47.5° to 55.5° North

4. Amount of reserves by different classifications
North Sakhalin crude oils are generally low in sulfur and paraffin, but high in
resins
API gravities reported for all fields range from 18°-62°
Low gas-oil ratios (GOR) and biodegradation are common
North Sakhalin Neogene – has 6.1 BBOE known,
61% gas, 36% oil, 3% condensate
32 onshore gas fields,

10. Type of drilling used; type of platforms (for offshore projects); information about drilling
activities; Extraction methods used in Sakhalin 1
Crechet Onshore drilling rig on
Odoptu field
• It drilled 9 wells of BOV and set several
world records for drilling.
• A new Krechet drilling rig, almost
identical to the Hawk, is used to drill
wells.
• The upper drive with a capacity of
about 2,700 hp is able to drill wells with
a large waste of slaughter from the
vertical length of about 13 kilometers
(42,000 feet) on the trunk.
• "Krechet" was manufactured in
Brownsville, Texas, specifically for the
Sakhalin-1 project and is the largest and
most powerful drilling rig in the
industry.
• To transport modules with a total
weight of more than 22,000 tons, it was
necessary to perform 18 flights in 2016
and 2017 during the period when the sea
was free from ice.

height of a 22-storey building and
has an electric motor top drive
capacity of 2,680 hp.
• It is designed to drill extended
reach wells to offshore targets from
land-based locations called
Extended reach drilling (ERD)
technology

oil, gas and refined products of Sakhalin 1
15. Sakhalin 1 Oil and gas reserves: the Sakhalin 1 project is estimated is 2.3
billion barrels of oil and 17.1 trillion cubic feet (Tcf) of Gas in recoverable
reserves.
Sakhlin 1 Oil: Sakhalin Blend to the Asia-Pacific region in 2014.
It is a light, low-sulphur oil blend. In total, 11 companies from four countries
purchased the oil blend in 2018. Products were delivered to Japan, China, South
Korea and USA.
Sakhalin 1 Liquefied Natural Gas (LNG): In 2018, Sakhalin Energy continued
to ship LNG cargoes to Japan, South Korea, Taiwan, and China. Sakhalin
LNG accounted for 4.8% of total LNG demand in the Asia Pacific and about
3.6% of global LNG demand.
Sakhalin 1 Natural Gas: In 2011, Sakhalin Energy began supplying natural gas
to the Gazprom pipeline system through two gas transfer terminals. The total gas
supply in 2018 amounted to over 1.12 bln cubic metres.
Sakhalin-1 LNG export terminal: The export capacity of the Sakhalin-1
LNG terminal is expected to be 6.2 million tons per annum (Mtpa).

16. Concerns over Endangered Species : the Stellar's Sea Eagle , western gray whale ,Salmon
fish
• Concerns about Oil Spills: -Problems in case of tanker accidents
• Pipeline: -Concerns of land erosion and water pollution due to 800km long land pipeline
• Dredging and Marine Dumping in Aniva Bay:-Damage to fishery resource due to
dredging and dirt dumping accompanying the construction of LNG plants and crude oil
terminals.
• Impacts on rivers and streams: changes occurred in the rivers like Pilenga River,Mereya
River,Woskresenkovka River,Golubichnaya River ,Bystraya River,Stolichnyi stream
Over 885.3 million barrels (118.2 million tons) of oil and condensate exported
• 939 billion cubic feet (over 27 billion cubic meters) of natural gas delivered to Russian Far
East customers
• Small Business Support
• Infrastructure development
• Community Contributions
Arising economical, geological, etc.
possible future development, importance for the economy, etc.
