One of the directions for increasing the recovery factor, effective development of uncovered reserves, as well as maintaining current production, is drilling horizontal wells (hereinafter referred to as HW). The paper considers and provides the analysis for all EMG fields that have current geologic and hydrodynamic models used to select and calculate the design horizontal well locations.
In the paper the authors defined the necessary conditions for increasing the efficiency of horizontal drilling, optimized the length of the horizontal section, analyzed well areas, examined the sector hydrodynamic models, carried out the factor analysis of actual flow rates and the analysis of the current operation of downhole pumping equipment, analyzed changes in the physical and chemical properties and the energy state of the horizontal well zones.
