Abstract

Summary

Condensates blocking in gas condensates reservoir cause loss of performance due to decreasing of gas relative permeability in terms of the existence of condensate in pore. Condensates are forming more in area near wellbore due to bigger pressure drop that occurs rather than any block in reservoir. Compaction significantly reduces the reservoir deliverability in early until mid-late production due to decrease of absolute permeability of rocks. The biggest reduction of absolute permeability is happened at near wellbore thus the productivity index which is used to calculate flow rate through wellbore become smaller. Compaction will induced reservoir deliverability when rocks are undergoing vertical stress that make behavior of rock change from elastic to plastic in terms of unconsolidated sand stone. The proposed equation of this research can be used to roughly predict the gas rate performance of gas condensate reservoir.
