Well productivity index

Recommended Posts

Hi,

how does Petrasim deal with one productivity index (PI), if the well intersects cells with different thicknesses (dz) and different permeabilities?

My assumption is that I have to calculate PI for each intersecting cell and then take an appropriate average?

Thanks for other thoughts on that.

The program does not seem to adjust the PI value based on the dz or varying k values. It does output the HG value, which is a cell thickness value. I believe that when calculating the PI for multi-cell wells, the dz would be the entire length of the well. I don't know what you would do in a situation with multiple k values. I would suggest that you submit this to the LBNL TOUGH2 forum, as the authors are better qualified to answer this question.

Thanks,

Alison
