Hi Sharma,

Please try 3 6 and 9 for inline, xline, twt or 7 8 and 9 for X, Y and twt

Cheers,

Hi Sharmaji...

The suggestion made by Mr. Azer will work.

But here I want to add few more suggestions regarding horizons....

In Petrel there are two types of layer exists... 1. Interpreted or Correlated horizon and 2. Gridded horizon which is known as surface in petrel. The surface is obtained by gridding the interpreted horizon.

When you import gridded horizon into any other software like OpendTect, you will not see the horizon at all Inline and Xline positions. This is due to the dimensions of the grid used while gridding (default in Petrel is 50x50). To overcome this problem, one has to export the Interpreted horizon and not surface.

So, if you have access to the Petrel project, export interpreted horizon rather than the surface.

Best of luck...

Hello Naik, 

Highly appreciate your response. 

It is an interpreted horizon, not a grid. 

I was able to reformat the file with just numbers, removing inline and xline text columns here....

Thanks

Hi Sharmaji..

It was not necessary to reformat the file two remove LINE, TRACE and : test columns. Just select Inl/Xlin and choose 3,6,9 as columns OR select X/Y and choose 7,8,9 as columns. You can save time by doing so. I think you might have used Excel to remove the unwanted columns. In case of large seismic volumes these  additional steps will take of lot time and it is also cumbersome to handle.

Naik, 

I am trying to use the 6.4.6 version so that I could connect directly with the Petrel 2017, that I use.... Mark provided the older Petrel plugin. But I am not able to initialize the plugin installed on the same computer. 

Do you have any suggestions?
