MANAGEMENT OF THE PRODUCTION PHASE IN ULTRA-LOW PRESSURE GAS CONDENSATE WELLS

Аннотация

Ultra-low pressure gas condensate wells are becoming increasingly relevant to the oil industry due to the growing economic and environmental importance of gas condensate. In gas condensate reservoirs with low permeability, the development of new production strategies aimed at maximizing output is becoming ever more critical.This study presents efforts directed at developing an optimization model designed todetermine rational switching times for ultra-low pressure gas condensate wells, taking into account changes in bottom-hole pressure and gas flow rates during production processes.To enhance the adaptability of production strategies, key parameters such as erosional flow velocity, critical liquid loading flowrate, and optimal differential pressure in reservoirs were considered.
