The Bolshekhetskaya Depression fields are the Company’s key gas producing assets in Russia. LUKOIL’s largest gas field is Nakhodkinskoye, which was put on stream in 2005. Oil production at the Pyakyakhinskoye field commenced in 2016, and its gas production infrastructure was launched in 2017.
Pyakyakhinskoye field is the Group’s second field put on stream in Bolshekhetskaya Depression.
The Pyakyakhinskoye field’s oil production infrastructure includes a metering station, a field support base, a pumping station to maintain reservoir pressure, an oil treatment unit, and a petroleum gas compressor station. The field’s major gas producing facility is a complex gas treatment unit.
2019, in a positive development for its production potential, the tax on
additional income regime was extended to the field. The field also implements
integrated models (separately for the oil and gas parts of the field) based on
the intelligent field concept.
Pyakyakhinskoye field has a challenging geology complicated by gas caps and oil rims; therefore its core assets are developed through the horizontal drilling, including drilling of multilateral wells. The unique for Russia oil reservoir development method of using both multilateral production wells and horizontal injection wells is protected by the patent.
The oil and gas condensate from the field are supplied to the Zapolyarye–Purpe pipeline. Marketable gas is transported via a trunk gas pipeline to a main compressor station (MCS) near the Nakhodkinskoye field and pumped to the Yamburgskaya MCS.
