How to tie well top and depth map in Petrel
Hallo everybody...
Let me introduce my self, my name is Zulmi. I'm a new comer here and working as CBM junior geologist.
I have a small problem with how to tie well top and surface depth map. Basicly, I knew those standard process but still confuse with the result. My well top doesn't tie with depth surface map. I guess it caused by limitted checkshoot of wells. My friend suggest me to make a residual map (difference between well top and depth map) but I don't know how to make it. After that, I can combine those map (residual and depth map). Is there anybody can help me, how to make that residual map?
Thanks/
