Nurlat Managing Department of Borehole Geophysical Investigations was established on the base of Nurlatsaya Expedition of Bugulma Borehole Geophysical Bureau in January, 1976 according to the direction of “Tatneftegeophysica” Trust.
In 2006 it was reorganized into TNG-NurGIS
The first task facing the Nurlat geophysicists was to determine the presence and amount of oil reserves in southern and southwestern part of Tatariya.
The beginning of drilling out the exploratory fields and their commissioning increased the scope of well logging considerably.
Nowadays the staff of TNG-NurGIS consists of highly qualified, literate specialists and workers knowing the complicated technique perfectly, performing and over-performing the tasks with geophysical data of good quality.
The geography of operations:
The investigations are carried out in wells of Bureykinskoye, Yuzhno-Nurlatskoye, Vishnevo-Polyanskoye, Demkinskoye, Mel’nikovskoye, Kiyazlinskoye, Aksubayevo-Mokshinskoye, Zyuzeyevskoye, Tcheremshanskoye, and other oil fields.
TNG-NurGIS performs borehole geophysical, geochemical, shooting operations in wells under drilling of Nurlat Drilling Managing Department, Almetyevsk Geophysical Exploration Expedition in producing wells of “Nurlatneft” Oil and Gas Producing Department, “TatRITEKneft” Oil and Gas Producing Department, “Kondurchaneft” Oil and Gas Producing Department, “Ideloil” CJSC, “Yamashneft” Oil and Gas Producing Department” ,“Tatnefteprom-Ziuzeyevneft” JSC, “SVAB” LLC, “Tatnefteotdacha” JSC, “Ulianovskneft” JSC, etc.
The following investigations are carried out in wells while drilling:
• Drilling control and spatial borehole position determination by high-prcision magnitometric and gyroscopic inclinometers;
Main tasks being solved for control of field development and technical state of producing wells are the following:
• The determination of oil-water and gas-oil contacts by methods of pulse and stationary neutron and spectral logging; inflow intervals and fluid content in producing wells; water flooding sources; energetic state of deposit in well and in the field on the whole; injectivity profile in injection wells; annulus circulation intervals by thermal log, flowmeter, moisture metering, resistivity metering, density metering, noise metering, barometry along with usage for tie-in of gamma-ray logging and collar location.
TNG-NurGIS is well prepared for carrying on the following experimental-methodical and research works:
• Optimization the complex of borehole geophysical and hydrodynamic investigations while workover;
