I believe the seismic line shown is the red line on the map running NE-SW. Look just north of this red line on the map and you will see the small closure and then an un-closed structural nose trending NE-SW, updip to the NE. Ths contours on the map may be in time, not depth. The potential for significant structual closure depends on the time to depth conversion and if the time-based structural nose coverts to a structural reversal.
