    Hello Jiri,

    Although there is not currently a direct way to calculate volume using three grid files, I believe you can emulate this by performing a Grid Math operation on all three grids ((top surface - bottom surface) * zfactor) and then performing a Grid Volume operation between that output grid and z=0. Please give this a try and let me know if this is or is not what you were looking for. In the meantime, I will add your vote to our suggestion file for the ability to apply a zfactor grid during volume calculations.

    Thanks,

    Leslie

    Hello Leslie,

    thank you for your fast response. I confirm that your suggested calculation works. In the meantime, I also tried to calculate it with slightly modified approach: Sum((top surface - bottom surface) * grid cell area * zfactor). The results differ from each other by less than 7%.

    Thank you,

    Jiri
