Fluid characteristic evaluation of Kailashtila gas field

Abstract

Pmduction data for many gas condensate pl'Oducing wells all over the world have shown thaI the productivity is severely cUJtailed when the flowing bottom-hole pressure is less than the saturation (dew point) pressure of the in-place fluid It is generally accepted th~t (his reduction is due to accumulation of condensed liquid near the wellborc. A reservoir simulation study by EXODUS (Implicit Compositional Simulalor) is conducted to address this issue for the Kailashtila gas field. fluid composition and phase behavior sludies are also conducted using gas chromatograph, PVT apparatus and HYSIM simulalor The results have revealed that the productivity impairmem due to condensate accumulation near the wellbore is 1101likely the case for the KaiIashliIa Gas Field during its entire depletIon life at the current rate of prod uctiOIl. Considering the natllle of the reservoir and nuid of the other existing flclds In Bangladesh, this conclusion can also be a benchmark for them
