Reservoir Top MAP!

[soman703]

Hello everyone,

I am reading a top map of a reservoir ( I have put it in attachments) .
I have a question please.

I can see on Top map that contour lines don't change towards right side of the fault.
While on left side ( towards well 3 and well 4) contours change.

Can I conclude from this that upper side and left side(well 3 & 4 side) have a sealing fault
while on right side we have non sealing fault because contour lines stay at same depth?

Can anyone please refer me to concise reference for all possibilities in top map interpretation of Sandstones?

Thanking you,
Soman

Hello Soman,
You have approximately 25m max of vertical change; look the thickness of your reservoir.

In your place I will check the depth of the gas-oil contact GOC and the oil-water contact OWC at well-1 and well-3, if they have approximately the same depth TVDSS, the fault isn’t sealing???
