The increase in hydrocarbon production in the Republic as a whole and in the South-Eastern part of the Bukhara-Khiva region is largely determined by the degree of discovery of new fields and the increment of hydrocarbon reserves. The main volume of production and growth of hydrocarbon reserves here is associated with the Jurassic carbonate formation, which for more than 40 years has been the main target object of prospecting, exploration and development of deposits. Due to the relatively high degree of study of the carbonate formation, the probability of discovery of large and medium-sized hydrocarbon deposits in the South-Eastern REGION is low. At the same time, hydrocarbon is increasing the share of small deposits being discovered. To improve the efficiency of development of these deposits and the degree of recovery of hydrocarbon reserves, it is necessary to justify new modern technologies. Since fields with oil deposits have specific features, we will consider this problem separately for oil and gas and gas condensate fields.
