Abstract
The Fingerdjupet Sub-basin was formed during Lower Cretaceous extension, creating accommodation space for Lower Cretaceous sediments. This study conduct a detailed sequence stratigraphic interpretation of the Lower Cretaceous deposits of the Fingerdjupet Sub-basin. Three wells have been drilled within the sub-basin, but none discovered sandstones at Lower Cretaceous level. However, these wells discovered mature hydrocarbons ( Jamil et al., 2014 ), and possible sandstone-prone clinoforms in the study area needs to be located to de-risk a new play type.
Several high resolution 2D seismic lines are selected for interpretation, where a complete sequence stratigraphic framework will be developed with the aim of identifying major surfaces, as sequence boundaries and maximum flooding surfaces. To enhance the interpretability diverse use of geophysical tools is used.
The scale and geometry of the clinoforms are important to predict if the clinoforms tend to be sandstone-prone or not. The observed clinoforms are classified into a diagnostic plot, where it is clear that it seems to be sandstone-prone clinoforms in the area.
