Scientific and Technical Management

The Scientific and Technical Management was established with the purpose of ensuring the scientific and technical progress in petroleum geophysics and introduction of Automated Control Systems in TNG Group. It conducts its activities in the following directions:

Conducting the scientific and research, experimental and designing, methological and analytical works in geology, geophysics, geochemistry and geoecology;

Manufacturing and customizing of tools and equipment, their assemblies, devices intended to carry out geological and geophysical operations;

Petrophysical provision of the geological and geophysical data interpretation;

Design, assimilating and introduction of computer technologies of different trends;

Development and introduction of means and methods of metrological provision of geophysical works.

Subdivisions of the Scientific and Technical Management:

Units engaged in scientific-research and experimental-methodical works for various types of logging operations (nuclear-magnetic, pulsed neutron, wave sonic), for geological and technological survey and well testing;

Hydrodynamic investigations of running wells equipped by low pressure electrical centrifugal pumps;

Subdivisions engaged in complex interpretation of well-logging data and automation of well-logging processing and interpretation systems

Experimental and production expedition for geological and technological survey in drilling wells (46 crews, Interpretation-Analytical Centre).

Metrological centre.

Owing to the developments by the Scientific and Technical Management, since 1960-s TNG Group has been one of the leading Russian companies in manufacturing and introduction of new hardware and methodical means of pulsed-neutron and nuclear-magnetic logging.

TNG Groups superiority in this field is generally accepted and confirmed by State Prizes of the Soviet Union, Industry Prizes after Academician Gubkin, medals and diplomas at the Exhibition of Economic Achievements. Designed and manufactured instruments for pulsed-neutron and nuclear-magnetic logging are used in many oil regions of Russia.

The Management provides the following services:

Creation of complex geological and geophysical data processing and interpretation method and technology while drilling and operating of horizontal wells and sideholes;
Development of computer technologies for determination and control over the current and residual formation oil saturation;
Development of well condition controlling technology, determination of the cementing quality on the base of wave acoustic logging methods;
Informational provision of the data base generation for hydrodynamical models construction;
Hardware and software adaptation for different geological and technical conditions;
Implementation of borehole investigations by special methods (pulsed-neutron logging, nuclear-magnetic logging, C/O logging, sonic-waveform logging) in Russia and abroad;
Creation of the methodical complex for Geological and Technological Investigations providing an operative evaluation of formation parameters and correction of the projected stem while drilling horizontal wells and sideholes;
Maintenance of slant, horizontal wells, sideholes.

The Scientific and Technical Management develops:
