Re: adding seismic amplitudes to a well log
I think there is a easier way (without gridding). Use the well log calculator to create a log from the seismic cube directly. Use the following formula:
If the cube is in depth already:
(*seismicCube_in_Depth is the name of the seismic cube converted to the depth domain)
If the cube is in stil in time:
(*seismicCube_in_Time is the name of the seismic cube; in TWT & TDlog is your Time to Depth relation)
To check your results it good practice to extract the seismic as you mentioned and see if all went correctly and remember to apply the same template as the seismic cube to the log. Now you can make cross plots with your data.
