Dear All,
Does anyone know how to treat salt domes in the gridding process of Petrel? I have my horizons as regular surfaces and my salt intrusion is triangle mesh but I fail to incorporate the tri-mesh in the gridding process? Do I have to treat it as a fault or what is the best way?
I can’t really generate a regular surface since the dome surface is a multiple z surface. Any help, suggestions would be most appreciated!
Hi,
MultiZ interpretation tool can help in the process.
Here a link to YouTube video presenting the tool: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=2ahUKEwjMhv2UscPiAhVHKVAKHRLDAWwQwqsBMAB6BAgnEAQ&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DeAqN5Q6Pq3Q&usg=AOvVaw1O0NPYb7j4U4v8l4itUnrZ
Hi Gerd,
I don't think there is a easy way to incorporate your salt body (triangle mesh) into your gridding surface process. One auick way to do it would be creating a closed polygon(s) of the area that intercepts the salt body and cropping the surface after is created. Of course is a simplistic approach but it's a quick solution that it may worth trying to see if it fits your need.
Hope that helps.
Cheers,
Hi Gerd Winterleitner
As the others mentioned before, Petrel has an interpretation tool called MultiZ interpretation (I hope your version includes that tool as it has been introduced a few years ago) which actually works exactly like fault interpretation. Using that option you can interpret your salt dome in a 3d body and then make a triangular mesh. Having all these done, you can have the salt dome modeled almost the same as other interpretation data.
Similarly, you can treat your salt dome like sedimentary channels and conduct the interpretation and modeling same as the way for channels.
Cheers,
Ali
