"Uralskneftegazgeologia" LLP

          The Government of the Kazakh Soviet Socialist Republic has decided in March, 1960 to create a consortium "Uralskneftegazrazvedka" for conducting oil and gas exploration in the Uralsk region. The first company office in Uralsk was located in the building currently occupied by the historical museum. Lev Dmitriyev has become the first general manager of the company, while Boris Khakhaev became the chief engineer and Ensun Kan became the chief geologist. Within the first year the company created three fully equipped exploration parties as well as the transportation and supply departments.
          In the 60-s, the consortium was involved in more than 59 exploration projects. Within a year of its creation, it became well known in the USSR and in 1961 it was assigned to drill Aralsorksaya well - one of two was approved for deep drilling with designed depth of 7000 meters - using a domestic drill rig. At the time, it was an impressive achievement. The crane for the assembly of the drill rig did not exist and the problem had to be resolved locally. The unique foundation for the drill rig was designed by Boris Khakhaev. The final depth of the well was 6808 meters.
           At the time, most of the exploration projects were conducted on salt dome structures. It is then that such oil fields as Bolganmoly, Chingiz, Beket, Kubasai (with 130-230 thousand tonnes reserves) and such gas fields Auketaichagyl, Port-Arthur, Karachai (with 150-300 mln cub. meters reserves) were discovered.
           In 1970, the consortium was renamed "Uralsk Enlarged Oil-Gas Exploration Expedition". Since then, the exploration work was primarily conducted in the Northern boundary zone of the Caspian Depression on the below-salt structures. However, the initial results of the exploratory activities were unsuccessful which led the Ministry of the Geology of the USSR to request cessation of the exploratory works. However, due to the confidence and persistence of the then-chief geologist A. Alzhanov, the works were continued. On 25th of March, 1969, the first fountain of gas-condensate was obtained on Well No. 5 in the West-Teplovskaya area. Subsequently, nine more gas-condensate and oil-condensate fields were discovered in this boundary zone. During that period, while efforts were made to discover promising areas, it became clear that the majority of the deposits were located at large depths and their recovery will be difficult.
           Understanding of the methods of drilling of complex wells has allowed for the growth in the expertise and professionalism of the geologists, engineers, and technologists. During that period, the core team of the knowledgeable professionals included Tarnacskiy, Nemtsov, Manakov, Gerasimenko, Belenkiy, Ermakov, Blinov, Kamalov, Ivanov, Bakhtiyarov, Alzhanov, Tovma, Lapshin, Zharylgasov, Zhukalin, Tyulegenov and others.
           A special achievement of our company is the discovery of the Karachaganak gas-condensate field in 1979. This field, marked by unique reserves and geological structure, was discovered by the drilling team of Mr. Lapshin. It was truly a defining moment for our company that was possible only due to persistent and selfless work of all geologists of our region. Currently, there are a lot of arguments who was the first to put a dot on the structural map. Ultimately, this is not so important. What was important was the development of the technology of mass drilling of wells more than 5000 meters in depth, mass demobilization and relocation of the drill rigs to the new site, and organization of the drilling on new wells. At the time, the company was headed by Mr. S. Kamalovwho through his persistence and dedication has created the team capable of solving these challenging problems.
           In a relatively short period of time, Karachaganak had 15 drilling teams. We have developed and implemented new technology for drilling and completion, new recipes for drilling fluids, and new exploration technologies. We have first used turbo drills using ISM drill bits for depths of 4500m and deeper. We have also used the program of lowering casings as one section and cementing them in one step at any depth. This allowed mass drilling of wells to depths up to 6500 m. During that time such talented specialists as geologists - Bakhtiyarov, Sumkin, Matlashinsky, Gainanov, Fomin, Khusnulin; drillers - Ermakov, Blinov, Stashkov, Prusakov, Lapshin, Zharylgasov, Tyulegenov, Zhukalin, Len, Podgornov, Chernyaev: mechanics - Ivanov, Kozhevnikov, Khakhaev, Iksanov, millwrights Soldatenko, Logovatovsky, Streltsov, ironworkers Soldatenko, Logovatovsky, Streltsov, supply workers Lyavinskov, Kustanovich and many others.
           We have to point out the immense contribution into the development of the oil industry of our colleagues from Uralsk geophysical expedition and North-Caspian well exploration expedition. During those years our company has been recognized as a leader in the industry and had a chance to showcase its deep-well drilling achievements at the All-USSR VDNH (National Trade) Fair. Thanks to the implementation of the modern geological methods, the exploration of the Karachaganak oil field was completed over a relatively short period of time (1979-1988) using few wells.
          In 1987, we have discovered a productive oil reservoir in the middle-devonian formations at depths over 6000 m. It is very sad that after the collapse of the USSR, the exploration works have stopped and neither the government, nor KIO (Karachaganak Integrated Organization, operator of Karachaganak field) conducted any exploration work.
           In 1991-2003, the Chinarev oil-gas condensate field was discovered. In 1993, the drilling team headed by the drilling master Mr. Len has completed the deepest well in Asia - Dolinskaya well , 7006 meters deep.
           Over the entire period of our company's activity, we have drilled over 390 wells with total depth of 1,300,000 linear meters, we have discovered 22 hydrocarbon fields including Teplovo-Tokarev-Gremyachin, Kamenskaya group, Dariinskoe, Chingiz, Port-Arthur, Karachaganak, and Chinarev.
           Since the very beginning, our company has paid a lot of attention to the community development issues. Everywhere we went, we built modern residential housing, schools, hospitals, children summer camps, saunas, clubs, shops, etc. Social infrastructure built by our company can be seen in Uralsk, Podstepnoe, Furmanov, and Zachaganskoye.
           After stoppage of government financing after the collapse of the USSR, we have started our partnership with JV "Kazakhturkmunai" which lasted for five years. Finding a partner among foreign companies was difficult since they considered us technically incapable of geological and exploration work. However, with time we have earned the trust of the oil field operators and in 1996, we have signed the contract with JV "Stepnoi Leopard" for well retesting. In 1998, we have signed the contract with "Zhaikmunai" LLP for drilling a well on Chinarev field where a drill rig F-320 was used.
           A milestone of particular importance in the history of UNGG after Soviet times was joining in a consortium of companies "Condensate" in 1998. This event gave assurance for the better future of the Company, a certainty that its services would be needed in oil and gas business, induced a sense of security. As a result, the same year the Company entered into its first contract with Zhaikmunai LLP for drilling wells in Chinarovsky field, where an F-320 drilling unit was rigged up with an excellent quality.
           This contract was followed by other ones: with MontazhMalikMunai LLP, JV Steppe Leopard, NBK LLP, KazakhTurkMunai LLP, etc.
           In 2005 UNGG rendered its services in drilling wells more that 5000 m deep, as well as their testing and workover in Chinarovsky field, wells 3000 m deep in Karatobe Yuzhnoye area (Aktjubinsk Region). The scope of exploration works for well drilling in 2005 exceeded 1125 million KZT. At year-end the net profit was more than 240 million KZT.
