Belorusneft does a full set of exploration activities and seismic exploration in Belarus and upon other requests of petroleum companies from Russia, Ecuador, Ukraine and India.
Belorusneft has at its disposal set of modern equipment and qualified staff able to perform the whole range of operations associated with exploration and seismic exploration.
85 oil and gas condensate fields have been discovered in Belarus to date. All fields are located within the Pripyat Trough in the south-east of the country.
61 of these fields are under exploration at the moment. More than 96 % of Belarusian is made up by 26 fields. Almost half of all remaining recoverable reserves of the company are located within 5 largest fields: Rechitskoye, Ostashkovichskoye, Vishanskoye, Yuzhno-Ostashkovichskoye and Yuzhno-Sosnovskoye. More than 71 % of enterprise’s accumulated production accounts for these fields.
By using up-to-date geological and seismic exploration methods Belorusneft and Belgeologiya experts discovered 22 deposits and 68 reservoirs of hydrocarbons from 2002 to 2018 in the well-explored Belarusian region. Over the same period Belorusneft put on the books 37 exploration targets.
Despite the fact that the Pripyat Trough is well studied, possibility to build up resource base and discover new deposits using geological and geophysical methods is limited. That is why follow-up exploration of existing deposits and increase of oil extraction factor are of the highest priority. Special attention should be paid to use of up-to-date technologies and unconventional approaches to exploration and prospecting.
We are conducting research aimed at finding unconventional reservoirs.
Belorusneft has developed a Prospecting and exploration program for Pripyat Trough up to 2020 and forecast up to 2023.
Search and exploration at Belorusneft enterprise is done by:
- Department of field seismic operations;
- Svetlogorsk drillingdepartment;
- Belarusian oil research and development institute.
Belorusneft experts of these subdivisions carry out a full set of exploration operations – from field acquisition, seismic data processing and interpretation, building geological and dynamic models to preparing integrated solutions for exploration and development oil and gas wells drilling methods are elaborated.
In 2015 Belorusneft opened Center for study, processing and storage of core material, which is unique for Belarus. More than 50,000 meters of core material is stored here with compliance to global standards. About 40,000 meters of core material was extracted during exploration works.
The enterprise carries out the following seismic exploration operations:
- 2D, 3D, 2D/3C, 3D/3С acquisition design;
- Topographic and geodesic services;
- Land 2D, 3D, 2D/3C, 3D/3С seismic data recording;

- borehole investigation stations АМЦ-ВСП-3-48;
- Echos 15.5, Focus 5.4, SPW, MESA software.
Seismic data processing and interpretation
Processing and interpretation of seismic exploration data acquired in Belarus and in foreign projects is done in BelNIPIneft R&D institute located in Gomel.
The center is fitted with modern equipment, Intel Xeon-based servers, connected by high-powered Infiniband bus into a calculating cluster. All the software is installed at Hi-End graphic stations. Processing results and the original seismic data are kept in a special 400 Tb data storage.
For seismic data processing:
- GeoDepth (Power 2D/3D);
- GeoDepth (3D MIG_CT);
- 3D Kirchhoff PSTM NexGen;
- 3D Kirchhoff PSDM NexGen;
- 2D pre-stack Kirchhoff & fx depth migrations – NexGen;
- 3D grid tomo- nexgen;
- Full azimuth anisotropic tomography;
- Tomo facilitator;
- Seismic Studio;
For structural interpretation of seismic data:
- Petrel 2016, SeisEarth XV, iMap.
For dynamic interpretation:
- AVO inversions, Probe, Fastvel, Vanguard, Stratimagic analyses and modeling, IFP Inversion, ComprehensiveAttr, SeisFacies, VoxelGeo.
In 2016 our enterprise fulfilled cameral seismic study 3D in the amount of 433 km2 for Severneft-Urengoy LLC, aimed at detailed elaboration of geological structure with forecast of porosity and permeability properties of rocks based on dynamic analysis, and 3D seismic exploration for RN-Stavropolneftegaz JSC in the amount of 185 km2.
Belorusneft possesses team of qualified specialists and set of state-of-the-art equipment to carry out seismic exploration.
Belorusneft branch office in Ecuador was established in 2012.
Major directions of activities of Ecuador branch office are as follows: complex seismic exploration, data processing and interpretation.
In 2015, a contract was concluded with Ecuador's state-owned oil company Petroamazonas for seismic 3D surveying at an area of 1,500 square meters. km and data processing on the perspective blocks 31 and 12.
In 2016-2017 years. for the company JSC "Service Oil Ecuador Ecuador" carried out cameral seismic studies 3D in the volume of 166.7 square meters. km at the Armadillo deposit (Block 55), which resulted in recommendations for drilling wells.
In 2017, field and office work was completed on the 11-A block with an area of 533.21 square meters. km. This is part of the project on the seismic exploration contract with Petroamazonas, which covers blocks 11 and 18 with an area of 2,000 square meters.
In June 2015, Belorusneft and the Indian company Oil India Limited signed a memorandum of understanding and an agreement on confidentiality. In 2017, Belarusian specialists completed complex works to increase oil recovery in the Digboi field. This is one of the oldest mining deposits in the world, opened in 1889. The successful completion of this project allowed "Belorusneft" in 2017 to win a tender for the implementation of a similar project - to increase oil recovery. This time at the Chabua field. In 2018 the contract will be completed.
The Belorusneft enterprise is ready to cooperate in the field of oil recovery enhancement, oil service as with the state oil companies of India - Oil India Limited, ONGC and other interested companies of the country.
Belorusneft is evaluating the seismic survey market in Ukraine as a promising one. The enterprise in 2017 began to perform field and cameral 3D seismic operations at several fields in Ukraine. The proximity of the region allows us to quickly mobilize qualified personnel, equipment and equipment. The total area of work is about 600 square meters. km.
