Croatian Oil Fields EOR Potential

Sažetak

Every oil reservoir is determined by many characteristics, such as: reservoir pressure and temperature, reservoir rock properties, crude oil type, its composition, density and viscosity. The consequence of such a large number of variable properties is great diversity of oil reservoirs. Therefore, not all oil reservoirs are suitable for EOR and not every EOR method is applicable to a certain oil reservoir.
The process of initial oil field EOR screening involves the inventory of all significant reservoir and fluid properties and their comparison with the applicability criteria of various EOR methods. This is the first step in defining the EOR potential in a broader area, and it will quickly highlight all promising fields / reservoirs suitable for EOR implementation while removing focus from unsuitable candidates.
This initial screening was conducted on all major oil fields in Croatia. The key properties for all reservoirs containing more than 1x106 m3 initial oil in place (and exceptionally, several smaller reservoirs) were listed and compared to published empirical criteria for applicability of EOR methods.
This paper presents the results of the initial EOR screening for Croatian oil fields. It further includes the total EOR potential in Croatia and applicable EOR methods.
