Belorusneft does a full set of exploration activities in Belarus, Venezuela and Ecuador and upon other companies’ requests.
81 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.
We are conducting research aimed at finding unconventional reservoirs.
By using up-to-date geological and seismic exploration methods Belorusneft and Belgeologiya experts discovered 14 deposits and 45 reservoirs of hydrocarbons in 12 years in the well-explored Belarusian region. Over the same period Belorusneft association put 44 exploration targets on the books.
The company objective is to build up resource base by means of additional exploration of the producing fields and their production enhancement. To do that we focus on cutting-edge technologies and unconventional approaches to selecting perspective regions.
Belorusneft has developed a Prospecting and exploration program for Pripyat Trough up to 2020 and further, and a standard of “Formation preparation for deep-hole drilling and grounding for exploration wells drilling” has been implemented.
Search and exploration at Belorusneft enterprise is done by:
- Department of field seismic operations;
- Svetlogorsk drilling department;
- 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.
The enterprise carries out the following seismic exploration operations:
- 2D, 3D, 2D/3C, 3D/3С acquisition design;
- Topographic and geodetic services;
- Land 2D, 3D, 2D/3C, 3D/3С seismic data recording;
- Shothole drilling;
- Vibroseismic acquisition;
- Refraction wave VSP survey;
- Geophysical equipment repair and technical support;
- Transport support of seismic operations;
- Seismic exploration QC;
Belorusneft specialists have experience in 2D, 3D, 2D/3C, 3D/3С seismic exploration. We design and implement high-density WAZ acquisition with both explosive and non-explosive sources.
For exploration Belorusneft uses state-of-the-art equipment and technologies:
- 428XL telemetry system with field equipment set for 14,000 DSU-3 three-component sensors;
- Borehole investigation stations;
- СВ-30/120Н vibroseis sources (truck-mounted);
- Mobile drilling rigs;
- Trimble©GPS systems;
- Geological and geophysical data integrated processing systems.
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 centre 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 150 Tb data storage.
For seismic data processing:
- GeoDepth (Power 2D/3D);
- GeoDepth (3DMIG_CT);
- GeoDepth (3DKPSDMFE);
- GeoDepth (3DKPSTM).
For structural interpretation of seismic data:
- Petrel (2009-2012).
For dynamic interpretation:
- AVO inversions, Probe, Fastvel, Vanguard, Stratimagic analyses and modeling, IFP Inversion, ComprehensiveAttr, SeisFacies, VoxelGeo.
In Venezuela JV Petrolera BeloVenesolana experts are engaged in geological supervision of oil production .
Belorusneft experts also carry out projects on oil and gas reserves estimation. Junin-1 license block resources estimation in the Orinoko river basin has been accomplished.
Seismic operations are carried out by Sismica BeloVenesolana joint venture.
JV Sismica BeloVenesolana is a leader of seismic exploration services in Venezuela. The enterprise has state-of-the-art equipment to do surveys of any complexity.
For prospecting and exploration work we use modern equipment and technologies, namely:
- 428XL telemetry systems with DSU-3three-component sensors;
- Trimble® GPS;
- STONEX electronic tachyometer;
- СВ-30/120М truck-mounted vibroseis source;
- EMCI drilling unit - tractor-mounted;
- SEDEDRILL drill unit truck-mounted;
- DOMOPOWER, LOMBARDINI, ASME portable drilling units;
- FOCUS seismic data processing complex.
On top of that Belorusneft is properly equipped to carry out operations using potential-field methods.
Successful projects in cooperation with Eni, Repsol, and Petrovietnam for joint ventures of PDVSA have been carried out. The scope of work of 2D for recent 5 years made up about 2,500 km, of 3D – over 520 km2. The work will be continued on Petropoiar and Petrocarabobo projects.
In 2012 Belorusneft branch office in Ecuador was established
Core business of Ecuador branch office is seismic exploration.
We are ready to mobilize two Sercel 428XL telemetric units (one of which is fitted with field equipment set for 4,500 channels, the other – for 5,500 channels) for potential contracts. Seismic acquisition design and seismic data processing are carried out using complexes with Focus 5.4 and Mesa Professional software.
Affiliated undertaking formation and successive increase of seismic exploration operations are planned.
Working plan of the branch office for 2012-2014 includes seismic survey in 2,000 km2 volume.
Belarusian experts participation into geological exploration of south-east of the country and producing fields development in cooperation with Petroamazonas state oil and gas company is being considered.
Belorusneft considers a possibility of starting seismic exploration business in Bolivia, Nicaragua, Uruguay, Columbia.
To carry out seismic exploration in these countries Belorusneft association is planning to use the equipment of its enterprises in Ecuador, Venezuela and Belarus, the enterprise is also willing to acquire technique specially designated for these projects.
