INVESTIGATING RESERVOIR MANAGEMENT TECHNIQUES TO MAXIMIZE LIQUID RECOVERY FROM A CONDENSATE RESERVOIR

Condensate reservoirs are faced with several challenges in maximizing hydrocarbon recovery due to retrograde condensation, changes in the fluid composition, as well as reservoir pressure depletion. Condensate gas reservoirs are an important source of hydrocarbons both in liquid and gaseous form, but their efficient development is often limited by retrograde condensation, which occurs when reservoir pressure drops below the dewpoint. This leads to liquid condensate trapping in the pore spaces, reducing gas flow capacity and leaving significant volumes of valuable liquids unrecovered. Maximizing condensate recovery therefore requires effective reservoir management and production strategies. This study investigates the techniques for enhancing condensate recovery, with emphasis on pressure maintenance through gas recycling and water injection, production rate optimization to minimize liquid dropout, and advanced completion and stimulation methods such as horizontal wells and hydraulic fracturing. The potential of enhanced recovery options, including gas re-cycling and suitable injection materials is also examined. Reservoir simulation tools are employed to evaluate phase behavior and to assess the performance of different recovery techniques under various operating conditions. The project aims to provide a clear understanding of the comparative efficiency of these strategies, offering practical insights for optimizing condensate production, extending reservoir life, and improving overall liquid / condensate recovery.
