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.

Abstract During the 2010-2011 seasons, analyses of 171 samples of fresh fruit from the south-eastern region of Poland were performed. The research program included the determination of 137 (in 2010) to 152 (in 2011) active substances, together with their metabolites and decomposition products. The analytical methods used in the research were gas chromatography (GC/ECD/NPD) and spectrophotometry (to determine residues of dithiocarbamates). The results were compared with Poland’s allowed maximum residue levels (MRLs).Residues of active plant protection product substances were detected in 85 samples (50%), while 7 (4%) samples had exceeded the MRLs.Violations of MRLs were mainly concerned with the following group of insecticides: cypermethrin (in black currant), esfenwalerate (in raspberry), and the fungicides: propiconazole, and difenoconazole (in gooseberries).

<p>Determination of the initial oil content of a reservoir starts from exploration activities. In the initial stage, the determination of the initial oil reserves is determined. This aims to determine whether the project can be profitable for the company or not. Over time the determination of the initial contents of the oil continues to be carried out to improve the accuracy of calculations using the material balance method.<br />In the reservoir "ADZ" the type of reservoir is an undersaturated reservoir. This is because the initial pressure in 1980 was 2762.74 psia, while the bubble point pressure was 1625.8 psia. Until 2015 this reservoir was still above the bubble point pressure with a pressure of 1783.55 psia, this reservoir also had no gas cap in the initial conditions. The drive mechanism that works on this field is the solution for the gas drive.<br />Calculation of the initial content of oil in this final project uses 4 methods, namely volumetric method, material balance method, straight line, and Mbal software. Using the volumetric method, the initial oil reserves obtained at the place amounted to 174063462 STB, while the calculation of the initial oil reserves in place using the material balance method was 176497285 STB. The percentage difference in the initial content of oil between the methods is &lt;5%.</p>
