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.
We achieved a steady increase in hydrocarbon
production at the Pyakyakhinskoye field. Also we began preparing the Yuzhno-Messoyakhskoye field for
commercial production launch.
Pyakyakhinskoye field is the Group’s second field put on stream in Bolshekhetskaya Depression. The average daily flow rates of the gas and oil wells at the field are over 300 thousand cubic meters and over 50 tonnes, respectively, which is two times higher than the average company-wide flow rates of the new wells.
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.
