The Bolshekhetskaya Depression fields form the backbone of the LUKOIL Group’s gas production, with the design production at the said fields reaching 20 bcm, and proven gas reserves totaling 2.0 trillion cu. ft. In 2015 production of commercial gas totaled 7.7 bcm.
The Company’s core active gas field is Nakhodkinskoye, commissioned in 2005. It accounts for most of the Company’s natural gas production in Russia (about 89%).
Nakhodkinskoye field accounts for most of the Company’s natural gas production in Russia (about 89%). In 2015 it produced 7.7 bcm of gas. As of late 2015 the field’s proven reserves were 2.0 trillion cu. ft of gas. The gas produced at the field is delivered via a 117 km long pipeline to the Yamburgskaya gas compressor station and on into the transportation system of PJSC Gazprom. Under an agreement between LUKOIL and Gazprom, all of the gas produced at Nakhodkinskoye is bought by Gazprom.
At other fields of the Bolshekhetskaya Depression preparations for bringing such fields into development were continued.
The sites have been using new technology, in particular, application of rotary controlled systems in horizontal drilling, which made it possible to bump up the overall drilling speed at Pyakyakhinskoye by 16.6%, which in its turn accounted for reduced well construction times and costs.
Pyakyakhinskoye Field In 2009 LUKOIL went ahead with the construction of infrastructure facilities at Yamal's new prospective Pyakyakhinskoye field. Commencement of the first production is scheduled for 2016 alongside with commissioning of the Zapolyarye-Purpe trunk pipeline (JSC Transneft).
In 2015 the Company commenced active development of the field that is set for commissioning in 2016. Drilling of oil and gas condensate wells goes on. As of late 2015, 60% of the main infrastructure facilities was completed, including erection of a gas treatment plant, oil treatment plant and petroleum gas compressor station. Transportation facilities are 55% completed. Infrastructure construction is complete.
The Company purchased a controlling stake in OJSC Yamalgazneftedobycha, holder of 4 mineral development licenses (within Bolshekhetskaya Depression area in Yamal-Nenets Autonomous Okrug).
In March Dr. Vagit Alekperov, OAO LUKOIL President and CEO, and Alexey Miller, Chairman of OAO Gazprom’s Management Committee signed a Cooperation Agreement setting forth the key parameters of gas supplies from Nakhodkinskoye field of the Bolshekhetskaya Depression. In October the gas supply agreement was signed.
LUKOIL West-Siberia LLC (a fully owned subsidiary of OJSC LUKOIL) started production drilling at Nakhodkinskoye gas field.
The Senomanian gas deposit of Nakhodkinskoye oil and gas field was put into operation.
Drilling of Pyakyakhinskoye’s first producer commenced. The Group is holder of mineral development licenses for six blocks within the Bolshekhetskaya Depression area and continues with the reserves revision in other licensed blocks, including South-Messoyakhskoye, Khalmerpayutinskoye, Vareyskoye and Salekaptskoye blocks.
LUKOIL and GAZPROM signed a 2012—2016 gas supply contract for LUKOIL’s fields located in the Bolshekhetskaya Depression area of YNAO and in the North Caspian.
LUKOIL commissioned the first stage of a base compressor station (BCS) at Nakhodkinskoye to supply gas from the Company’s fields located at the Bolshekhetskaya Depression into OAO Gazprom gas pipeline system.
LUKOIL and GAZPROM signed a supplementary agreement to the gas supply contract for LUKOIL’s fields located in the Bolshekhetskaya Depression area defining gas supplies for 2017—2024.
