Most oil and gas fields in the Uzbekistan are at the final stage of development, with declining component recovery and final recovery factors and increased risk of additional development, which leads to considerable economic costs. This is the case for the South Kemachi oil, gas, and condensate field in Bukhara Region, Uzbekistan, which has a range of process complications mainly related to production decline. The existing issues include flow rate decline and water entry to vertical gas-producing wells, corrosion wear of tubing and other downhole equipment, low reservoir pressure in the pool, the difference between the actual and design performance due to the decline in the component recovery of the pay formations, non-profitability of the additional development base case. The potential condensate content in the produced gas is almost halved in the pool. To resolve these issues, it is considered to introduce horizontal wells into the South Kemachi oil, gas, and condensate field development system in 2022 by side-tracking the vertical wells existing in the stock. Importantly, in this study, the possibility of using horizontal wells to develop gas-saturated pay formations in this field is considered for the first time. The aims and objectives lie in the feasibility study and selection of the recommended additional development case to ensure enhanced component recovery of South Kemachi and the highest profitability. A rational case is proposed to facilitate the maximum hydrocarbon recovery at the minimum capital and operational expenditures and production cost price.
