montara & plover formations, page-115

Looking at the contours, the closure of the rings at A & C suggest their locations on a 'structurally high' block.

The pale blue between the yellow colors is a valley, so definetely a no-drill zone.

Tight packing of the contours on the rightside or west of Caelum again shows an uplifted the block is called 'Horst', hence ideal location to drill at the closure where u expect maximum accumulation of hydrocarbons.

The pink could simply denote the shelf sloping away to the left/east of the Crux uplifted block.

Looking at the locations of A&C, it looks impressive as they are located on a dome shaped formation so chances of encountering HC's should b high unless of course they are water saturated, which I hope not.

Is there a seismic cross section that u've seen, that shows all the faults in the area, which need to b avoided as they can juxtapose these sands to different intervals in the field.

I'd say there should b plenty of faults at deeper intervals, thats how u get a raised block & a down-thrown block (visualise being on top or bottom of a staircase, when i say up/down throw block thats what the yellow & blue indicate on the contours).
