Denisovskaya Depression accommodates Eastern-Laybeshorskaya and Bayandyrskaya field groups. Eastern-Laybeshorskoye field is located in Usinsk District of the Komi Republic, 115 km to the north-west of Usinsk. The field was discovered in 2011, and its trial development began in 2012. The mineral development license is valid until 2023.
Bayandyskoye field was discovered in 2007, and its pilot development began in 2008. In 2014 the Bayadynskaya Oil Treatment Unit adopted an associated petroleum gas (APG) recovery flowsheet, and used it to meet its own requirements or turn the gas over to the Usinsk Gas Processing Plant.
The year 2015 saw commissioning of a 52 ths. tn/year sulphur recovery and granulation unit at Bayadynskaya OTU, oil treatment facilities at Eastern Lambeishor OTU (1.3 mln. tn. per year) and outside facilities supplying power to the Eastern-Laybeshor group of fields.

Bayandyskoye field discovered.
Pilot development of Bayandyskoye began.
LUKOIL was the first Company in the world to use aluminum casing and tubing in building wells at an oil field with high concentrations of hydrogen sulphide and carbon dioxide. This technical solution was used at Baydynskoye field (Komi Republic) which shows high concentrations of the said aggressive components. Eastern-Lambeyshorskoye field discovered.
Eastern-Lambeyshorskoye brought into pilot production.
Three oil fields were discovered, including South-Bayadynskoye, West-Syurkharatinskoye and A. Alabushin fields. LUKOIL-Komi set a new record at Eastern-Lambeyshorskoye by drilling a well that is 5,409 meters deep and exposes a 1.5 km long stratum.
A sulfur recovery and granulation unit commissioned at Bayandyskoye field. The new equipment will make it possible to fully remove hydrogen sulphide, thus ruling out any potential discharges into the environment and enable an annual output of 50 ths. tn of granulated sulphur used as raw stock in the chemical industry.
