Nadra Geophysical Equipment, JSC
Plant history
Kyiv Plant “Geofizprylad” has been a production base for the geophysical equipment manufacturing of our country over the last 60 years. Production output of thousand instruments per year, supplies of equipment to many countries of the world, test prototypes of newly developed products – all these successes are indicative for the large scale and flexible production capacities, high quality and technological perfection of the products.
Kyiv Plant "Geofizprylad" is established in 1945 as a subsidiary of the factory "Geofizyka" of the State geological trust of the USSR. Its core business at that time was the production and maintenance of equipment for field geophysical units.
On February 13, 1951 the subsidiary has became an independent company named as “Kyiv Plant of Instrument Engineering”, being at the beginning under control of the Ukrainian Survey Trust “UkrNaftoGeofizyka” and later on – of the company “SojuzNeftePribor”. Since 1988 the plant has been under control of the Ministry of Geology of Ukraine.
In the period of 1970-80 the plant has been producing up to 2000 logging tools per year. As a matter of fact, more than 80% of the well logging equipment used by the soviet geophysical companies in their oil and gas exploration operations has been made by the Kyiv plant "Geofizprylad".
On June 18, 1996, by decision of the State Property Fund of Ukraine the state-owned Kyiv Research and Experimental Plant "Geofizprylad" has been transformed into an open joint-stock company.
Since November 1, 2007 the plant has been reorganized in the Closed Joint-Stock Company “Kyiv Plant "Geofizprylad".
Pursuant to the relevant changes of the laws of Ukraine and restructuration of the NADRA Group, on May 17, 2011 the Closed Joint-Stock Company “Kyiv plant "Geofizprylad" is renamed to the Joint-Stock Company “NADRA Geophysical Equipment”.
Today NADRA Geophysical Equipment represents technologically closed production cycle having all necessary equipment and technologies for manufacturing of the full range of well logging tools and equipment.
Organizational structure of the Plant
Organizationally, the Plant is composed of the following units:
- Chief Designer’s Department composed of 6 laboratories and an Engineering Design Bureau;
- Chief Technologist’s Department;
- Metal-processing shops, including turning and milling shop; thermal treatment and hardening shop; electroplating shop, stamping, pressing, special process technology shops etc.;

Manufacturing
NADRA Geophysical Equipment operates a technologically integrated production cycle that includes manufacturing of heat- and pressure-resistant downhole logging tools, metrology and certification.
Core line of the Company’s business is the production of geophysical equipment and downhole tools designated for survey boreholes in the exploration of mineral deposits.
The Company carries out a full production cycle - from the research and designing to serial production including hundred percent testing of prototypes and serial products. The Company also attracts specialized designing institutions as subcontractors for development and designing of complex and high-end equipment and tools.
Lately, and in order to be in line with the best international standards, NADRA Geophysical Equipment has implemented a computerized designing system for the development of new products and carries out a technological upgrade of the production capacities that allows to react operatively on Customer`s requirements and to improve the quality of products as well as to increase their competitiveness on the market. The Company has adapted and implemented advanced technologies to upgrade the existing production capacities. This upgrade concerns the following:
- Re-organization of the production infrastructure;
- Optimization of the production processes; and
- Reinforcement of the existing design- and-engineering department by hiring the best designing specialists having appropriate knowledge and skills in the up-to-date designing methodologies.
The production processes are upgraded with up-to-date technologies and the best control/ metering and testing equipment.
Technically upgraded production process and implementation of the relevant control methods allows meeting the high quality standards at each stage of the production process.
In 2005 the Company completed the first stage of the complex technical re-equipment of the production process. Now each step in the designing of new products and development of new manufacturing technologies are performed in accordance to the international standards by using computerized working places. The Company has procured and implemented new integrated hardware and software for 3D designing and engineering solutions with modeling and designing calculation capacity – from PTC Company (Pro/ ENGINEER i WihoFIRE 3.0).
