The northeastern section is known as the Taurus Mountains zone. The zone is characterised by a propensity to medium-to-heavy oil finds. Geologically, the area shows a relatively large range in recovery factors, a tendency to oil finds with large in-place resources and a low-to-medium exploration risk.
The northwestern section named the Taurus Foothills zone, is characterised by a tendency to heavy oil, a relatively low geological risk and large in-place resources. The Gulf Keystone-operated Shaikan field has demonstrated the area's potential.
The southwestern section, the Zagros Footlhills zone, shows a high propensity to large oil and gas condensate fields. With a relatively low geological risk, the area has revealed a tendency to higher gas-to-oil ratios. The zone is in close proximity to a fair amount of existing infrastructure, for example the Kirkuk-Ceyhan pipeline.
The southeastern section, the Zagros Mountains zone, shows a higher propensity to gas finds with less frequent oil shows. A mountainous area, it poses a number of operational challenges with medium to high technical risk and cost.
