The East-Tarkosalinskoye  field was discovered in 1971 and is located 40 kilometers to the east of the city of Tarko-Sale. The field’s license for exploration and production of hydrocarbons is held by NOVATEK’s wholly-owned subsidiary OOO NOVATEK-Tarkosaleneftegas and is valid until 2043. The field began producing crude oil in 1994 and natural gas and gas condensate in 1998 and 2001, respectively. Currently, the East-Tarkosalinskoye field has reached its peak production capacity for natural gas and gas condensate production. The Company’s field development plan will focus on maintaining production levels and developing new crude oil layers. The field is connected to the UGSS by a 22.4 kilometer natural gas pipeline with diameter of 1,020 mm which enables the transport of up to 20 bcm of natural gas per annum.

 

The East-Tarkosalinskoye  field  has one dry gas layer with an area of approximately 950 square kilometers, the top of which occurs at a depth of approximately 1,200 meters. The field also has 13 gas condensate layers which occur at approximate depths of 2,850 meters to 3,000 meters, the largest of which has an area of approximately 125 square kilometers. The field’s 11 crude oil layers occur at approximate depths of between 3,000 meters to 3,200 meters over an area of approximately 1,100 square kilometers.

 

In December 2009, the Company launched the second stage of the compressor booster station at the East-Tarkosalinskoye’s cenomanian (dry) gas field with capacity of 48 MW allowing NOVATEK to maintain dry gas production levels at the field despite decreasing reservoir pressure.
