Thank you on elaborating the process of calculating compressibility by eclipse. But somehow in my case i could not figure out the corrective measure for my PVT table. So i generated one with petrel 2013 using default empirical correlations with 20 nodes. But this table also gave me the same negative compressibility error since start of my run. So can u please attach the .xls file again.I shall be thankful to you.
