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
