* The testing of new methodologies for working with low-permeability reservoirs is being undertaken through the national “Developing Domestic Technologies and High-technology Equipment to Develop Reserves at the Bazhenov Formation” project, on which the Gazprom Neft Bazhenov Technology Centre is operator. The project includes both a technological element, and facilities for state support. 2019 saw the adoption of amendments to subsoil legislation, envisaging a new kind of subsoil use regime in Russia, designed specifically to facilitate the development and testing of new technologies. Once these changes come into force Gazprom Neft will be able to make access to Russia’s first pilot testing facility at the Bazhenov Formation fully available to third-party companies.
** Hydraulic fracturing (fracking) is one of the most effective means of increasing oil production at a field, and increasing oil recovery. It involves the high-pressure injection of a mixture of fluids and a proppant into oil-bearing strata, at depths of several kilometres. This operation creates fissures in the rock, allowing oil to flow into the well. The longer these fissure are, the larger the reservoir area they cover, meaning more hydrocarbons can be produced.
The Bazhenov Technology Centre — a subsidiary of Gazprom Neft — is operator on a national project, “Developing Domestic Technologies and High-technology Equipment to Develop Reserves at the Bazhenov Formation”. The project is directed at bringing together the resources of the scientific, industry and business communities, together with government, in developing profitable technologies for developing the non-traditional hydrocarbon reserves of the Bazhenov Formation. The Bazhenov Technology Centre’s production programme to develop non-traditional hydrocarbon reserves is being implemented in the Khanty-Mansi Autonomous Okrug.
The Bazhenov Formation comprises a group of oil-bearing rocks covering an area of approximately one million square kilometres in Western Siberia. The formation lies at a depth of two to three kilometres. Provisional forecasts indicate geological reserves at the Bazhenov Formation to be in the order of 18 to 60 billion tonnes. There are not, currently, any effective technologies for working with the Bazhenov Formation.
