Waste management and land use
The two key pillars of industrial waste management and land use at the company are equipment reliability monitoring and the implementation of new technology. These efforts minimise the risk of soil contamination by crude oil and petroleum products. The company also successfully recycles its production waste.
Large quantities of waste are safely disposed of every year, thanks to improved waste recycling and treatment processes across the company. The Omsk Refinery’s efforts to find alternative contractors resulted in increased treatment and recycling of oily sludge, with higher volumes of drilling waste processed by the company’s upstream assets.
The bulk of the company’s waste is drill cuttings produced in the course of hydrocarbon exploration and production. The company’s drillingwaste management framework is designed to reduce environmental risks and standardise waste management requirements.
Drilling rigs currently in use across Gazprom Neft are equipped with a drilling-waste cleaning and drying system to reuse drilling fluids and process water in well drilling.
The company seeks out and implements new technologies to utilise waste in the production of commercial products. In 2020, two public consultations were held on the following agenda:
- technical documentation for new technology to produce and use YAKHONT, a man-made soil based on cuttings (pieces of rock removed by drilling);
- technical documentation for new technology to make pavements on roads and other transport structures using BRIT construction sealant.
Green Seismic project
Gazprom Neft has been developing Green Seismic technology since 2014, which, thanks to its compact size, significantly curbs the number of trees felled for seismic lines and cuts fuel consumption for seismic surveys, all while improving safety. The first phase (Green Seismic 1.0) reduced line width fourfold. This technology saved over 4.5 million trees between 2016 and 2020 over an area of about 3,700 sq km. The current Green Seismic 2.0 project aims to considerably reduce source line width to save even more trees: between 1 and 1.5 million per year.
