In case you don't have enough data from cores can u use also DST data and MDT data u have available?
MDT points are not the same as core points.
For MDT u have effective permeability compare with cores were there is absolute permeability (meassurements are done with gas on clean core)
DST means one meassurement for entire reservoir and there is one value for KH meassured in md*m

How can this be used toghether?
