It is impossible to study the effect of PSS on CIN without using¬statistical methods that allow not only to state the facts, but also, what is especially important, to find out the reasons why the influence of PSS on CIN varies in different mining and geological conditions of oil deposits.To date, a huge amount of material has been accumulated on deposits that are at the late and final stages of development, the synthesis of actual data on these deposits is of particular value for solving many controversial issues in the field of assessing the impact of certain technological solutions on the efficiency of implemented development systems.

The World Gold Council and its member companies support the responsible mining and trading of gold from all legitimate sources, including artisanal and small-scale mining (ASM). The responsible development of gold resources both through large-scale mining (LSM) and ASM, especially when coupled with sound governance, has the potential to deliver broad social and economic benefits to individuals, communities and countries. There has been a significant growth in artisanal and smallscale mining in many developing countries over the last twenty years. ASM issues have become more salient in public policy debates as a result of the adoption of instruments designed to prevent the funding of illegal armed groups and from the implementation on reducing mercury in the environment. Artisanal and small-scale mining is more than simply an industry with the potential to contribute positively to foreign exchange earnings and employment; it is a way of life. Its participants, most of whom were lured into work by the prospect of gaining wealth quickly, include rural community dwellers, nomadic peoples, seasonal subsistence farmers, and retrenched largescale mine workers. However, despite providing higher wages than comparative rural sectors of industry, artisanal and small-scale mining is generally associated with a deteriorated quality-of life KEYWORDS Small-scale gold mining, explosive, gold mining, well spacing, rock, rock mass, blasting, rock strength, open pit mining, parallel-close charges.

The increase in hydrocarbon production in the Republic as a whole and in the SouthEastern 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 SouthEastern 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.

The article examines the methods of increasing the productivity of wells of gas and gas condensate reservoirs in the south-eastern part of the Bukhara-Khiva region (BHR). The role of gas calculation methods in determining the gas reserve of Mesopotamia in sveza with an increase in the share of gas reserves from 1 to 10 million tons of conventional fuel is shown. Certain difficulties have been identified in the issue of reliable determination of gas reserves in the limited fund of wells and large ranges of changes in calculated parameters. The determining significance of the value of gas reserves in calculating the forecast indicators of the development and technologies of their extraction is justified. It is established that increasing the degree of reliability of calculating gas reserves ensures the efficiency of its extraction, as well as the rational use of material and technical resources and financial capabilities of the enterprise. The advantages of such methods for determining gas reserves as the volume method, the material balance method, and static models are disclosed. A specific description of each of these methods and their application for calculating gas reserves at the Northern Guzar field is given.
