TNG-Izhgeophysservice

 

TNG-Izhgeophysservice is subsidiary company of TNG-Group.

TNG-Izhgeophysservice carries out all spectrum of borehole geophysical investigations and operations for more than 15 oil and gas producing companies in Udmurtia, Tatarstan, Yakutiya, Irkutskaya, Orenburgskaya, Permskaya oblasts and in Uzbekistan Republic.

  ..

The following tasks are solved in wells while drilling including horizontal wells:

∙ Drilling control and spatial borehole position determination by high-precision magnitometric and gyroscopic inclinometers.
Lithological section dismembering, reservoir detection with quantitative determination of its properties and saturation character by the complex of radioactive, induction and dual induction, lateral, microlaterolog, dual lateral and microlaterlog survey of scanning type, micrologging, standard normal logging sonde, lateral sounding, wave acoustic and litho-density, nuclear-magnetic logging methods, induction mud resistivity log.
Operative detection of oil and gas saturated formations in drilling well sections, determination of their occurrence depth according to geological and technological investigations and mud logging.
Testing of the prospective section intervals by tube formation testers and by testers on cables with sampling.
Well casing and cementing quality determination by gamma-gamma and acoustic cement bond log sondes including scanning modifications.
Orientation of whipstock using small-sized gyroscopic inclinometers (Ø 42 mm) while side-tracking.

The following works are held on well completion stage:

Jet and auger perforation (on wire and on tubing) of flow string with control of completion efficiency and perforator actuation
Well completion by swabbing method or by injector pumps with the determination of hydrodynamic formation parameters.

TNG-Izhgeopysservice has the experience of carrying out the geophysical investigations more than 300 horizontal wells located all over the Russia: Udmurtia, Tatarstan, Sakha (Yakutia), Irkutskaya, Orenburgskaya and Permskaya oblasts and abroad: Republic of Belarus, Uzbekistan, India (Assam State).

 The following tasks are solved concerning the control of field development and workover:

determination of oil-water and gas-oil contacts by pulsed and neutron stationary logging;
determination of inflow intervals, flooding sources and fluid content in production wellbore, including annular space, without well shutdown;
determination of injectivity profile and intervals of fluid annular circulation in injection wells;
determination of the shape and the size of production string damages; bench mark, packer and bottom-hole locations using methods of electromagnetic flaw detection, borehole acoustic televiewing, radioactive well logging, microcaliper logging and collar location;
ecological monitoring of technical and drinking water safety by unique technologies.

For oil recovery enhancement of the productive formations and to increase well injectivity, cable technologies on formation stimulation are used: thermal-gas and chemical, perforation and depression, thermal and gas depression and acoustic technologies. Stimulation effectiveness reaches 80 %, its duration is 3-6 months, and productivity of the wells increases up to 2-5 times.

All logging crews, serving the drilling wells and complex crews, conducting investigations in the producing well stock, are provided with up-to-date hardware and software that allow to conduct preliminary processing of the results of investigations in the well site and to deliver geological conclusion to the client in electronic form and as hard copies.
