This paper analyzes the ratio of local and regional anomalies of fluid saturation identified in the southern margins of the Eastern European Platform by remote fluid indexation. A characteristic feature of this area is the very low background values in the initial field, i.e., local anomalies reflecting the deposits. Regional anomalies are mainly related to oil and gas accumulation zones. In the Middle Caspian areas studied, the regional field of the fluid saturation index is the background for local anomalies. We made an attempt to justify the hydrocarbon migration and generation zones as anomaly-forming zones of the regional anomalies. The correlation of oil and gas accumulation zones with the regional field anomalies was noted.
