Oil and Gas
BULGARGEOMIN is an international contractor, a regular member of IADC and IPLOCA, operating in the field of prospecting, exploration and production of oil and gas.
DRILLING OF OIL&GAS WELLS
BULGARGEIMIN carries out all the drilling, completion and testing operations according to the high standards and requirements of the American Petroleum Institute (API) and the modern world-wide best practice. Advanced technologies and methods are being applied like directional drilling, including horizontal intervals, etc. for efficient development of the oil deposits. The key personnel of the company is highly qualified and certified upon attending specialized courses conducted by API authorized training centres.Drilling rigs, such as IDECO - 1200, IDECO - 1700, SKYTOP - NE 95E and CARDWELL KS 600 - 101 are used for drilling operations.
GEOLOGICAL MAPPING in scale 1 : 1 000 to 1 : 25 000 with the relevant geochemical, radiometric and other surveys:
GEOPHYSICAL SURVEYS
- Aeromagnetic and gamma – ray spectrometric analyses
- Gravimetric surveys
- Magnetic surveys
- Chemical analyses
SEISMIC
SURVEYS
The
following methods are applied :
- CDR with coverage 1200 to 6000 %
- Geoflex
- Vibroseis
- Portable seismics.
Sophisticated equipment is used such as MDS 16 seismic units of 48 to 120 channels. Up-to-date drilling rigs, tractors, and safety explosives are used for generation of the seismic energy.
A special cable
“flexotir” is used for work under the “geoflex”
method. The surveys are performed mainly under the CDR – method
with 1 200 to 6 000 % coverage depending on the geological conditions.
Groups of geophones are used - 48 geophones per trace the parameters
of which are continuously up-dated so as to respond to the requirements
of the surveys.
Geological interpretation of the collected information, calculation of reserves and designs for development of deposits with mathematical models are also carried out. To this end BULGARGEOMIN has at its disposal all the required computer equipment and programs.
EXECUTED PROJECTS
OIL CONCESSION ACTIVITY
Exploration and Production Sharing Agreement (EPSA) effective since
1980 for 25-year period with the Libyan National Oil Corporation
for Blocks NC-100 and NC-101, Libya - presently under execution
PROSPECTING AND DEVELOPMENT OF OIL AND GAS FIELDS
Iraq
- Seismic surveys in Iraq for the Iraq National Oil Company (INOC) with the
use of up-to-date seismic units, such as VIBROSETS, DFS-IV, DFS-V,
with computer COMMAND II, for electronic data processing.
- Drilling of 4 000 m (13 200 ft) depth wells in the oil fields
of Iraq for the IraqNational Oil Company (INOC).
Syria
Further exploration of the gas deposits in Jbisseh areas –
Syria and their development with the purpose of their exploration,
for the Syrian Petroleum Company, on “turn key” basis,
inclusive of: Repair of 12 old wells; Drilling of 20 new exploratory
wells, of which 9 wells to 4 500 m (14 800 ft) depth and 11 wells
to 1 300 m (4 300 ft); Drill-stem and stationary tests of the wells
for determination of their hydrodynamic parameters; Chemical, physical,
PVT and other analyses on rock samples and fluids; Drawing up of
reports for the gas reserves and elaboration of alternatives for
exploitation of the deposits ensuring
optimum gas recovery; Development of the gas deposits by drilling
32 production wells to 1 300 m depth; Preparation of designs for
the erection of gas-processing plant; Preparation of fluid analyses
and recommendations for utilization of gas in the Syrian Arab Republic.
Yemen
Drilling of exploratory oil wells in Yemen for the Ministry of Oil
and Mineral Resources, AGIP and TOTAL.
Kazakhstan
Drilling of 4 exploratory oil wells for TEXACO in North Buzachi
– Kazakhstan (1000 m horizontal interval at each borehole)
