Predictive Models for Condensate Gas Ratio (CGR) – Part 1: For Western Niger Delta Region

Abstract

Condensate-to-gas ratio (CGR) playsa significant role in sales potential assessment of both gas and liquid, design of the required surface processing facilities, reservoir characterization and modeling in gas -condensate reservoirs.This work aim at the use of regression method to develop Condensate gas ratio (CGR) correlations using dataset obtained from Western Niger Delta region. The formation was divided into three distinct geologic zones: Transitional Paralic, Paralic and Marine Paralic zones. The basic parameters used for the correlatio n development are: reservoir depth (ft), reservoir pressure (psia); reservoir temperature ( o
