The substantial reduction in the volume of heat consumed for oil production processes in 2015 is attributable to the implementation of an energy conservation programme, the preservation of production sites and changes in ambient air temperatures in 2014 and 2015.
Electricity expenses make up a large portion of the operating expenses for oil production. A key energy efficiency indicator at the enterprises of the Exploration and Production Unit is the specific consumption of electricity for liquid hydrocarbon production. In 2015, this indicator declined by 1% compared with 2014. The energy efficiency programme exceeded its target by 92%. The Unit had energy savings of 205 million kWh (RUB 640 million).
Highlights of 2015:
- use of high efficiency electrical submersible pump units;
- introduction of permanent magnet motors;
- operation of downhole equipment in periodic operating modes;
- reduction in water produced and its pumping into the formation (shutdown of unprofitable wells and performance of geological and technical measures);
- selection of the optimal size and replacement of pumping units at water-injection and booster pumping stations and initial water separation units;
- installation of variable frequency drives on pumping equipment;
- reduction in power grid losses.
Construction of gas turbine power plants
Gazprom Neft has launched construction on a gas turbine power plant (GTPP) at the Novoportovskoye field with projected capacity of 96 MW and the ability to expand to 144 MW. The plant will be one of the largest on the Yamal Peninsula. Both natural gas and associated petroleum gas may be used as raw materials for the future power plant. The GTPP will supply electricity to infrastructure facilities that extract, transport and store hydrocarbons as well as a year-round crude oil trans-shipment terminal that is being built near Mys Kameny. The new GTPP will make it possible to avoid a shortage of generating capacity by providing stable power supplies to the project’s facilities and enhancing its industrial safety.
