Abstract:
Oil in the Vincent Field is uniformly derived from gas and light-oil prone Jurassic source rocks. However, fluid samples from different parts of the reservoir show highly variable solution GOR and in-situ viscosity.The excellent reservoir quality and lack of significant faulting means that conventional compartmentalisation is unlikely to be the cause of this variation. A geochemical study of oil and gas samples together with numerical mixing modelling has explained the origin and persistence of the observed fluid property variability.
