Abstract

Summary

Currently, one of the problems in the oil and Gas industry is the difficulty in reaching a high condensate recovery in gas condensate reservoirs. Liquid dropout usually occurs in these fields, when pressure decreases below the dew point, especially around the well bore. Gas cycling/injection is a common practice used in industry to alleviate this problem and enhance condensate recovery by preventing condensate liquid loss and to help re-vaporizing retrograde liquid.

The aim is to investigate the lean gas recycling to enhance condensate recovery. In this work, the effect of CO2, Separator gas and N2 on Condensate recovery enhancement was investigated.

The revaporisation of condensed liquid during different injection volumes was most for N2 followed by Separator gas and CO2 respectively. In other words, N2 is the most effective and Co2 is the least effective scenarios in reduction of condensate in the Synthetic model that the decreasing condensate being due to the direct effect of gas injection on the fluid properties in porous media, while, this result may differ with injection of the three gas in a PVT Cell because of diffusion effects and also influence of porous media on the increasing pressure process.
