Chalk Project. Oil- and Gas Containing Chalk Reservoirs in the Danish Part of the Central Graben. Pt. 5 G. I-1 ''KALKPLOT''. Cross-Plots of LOG- and Core Data from the Chalk Group

摘要

The aim of this report is to present the variation of some reservoir parametres of the Chalk Group and the various Chalk Units, as they can be outlined from available log- and core-data. The Chalk Units are defined in the ''Chalk Project Report,'' no. 2 c. FDC-SNP, raw log-data, are cross-plotted against each other and against core-porosity to establish porosity corrections. SNP vs. deep-resistivity are cross-plottet to estimate m-and a x Rw values, which are used as input parametres for the CPI-run, together with other parametres. From the CPI-run is found cross-plottet porosity values, corrected for clay influence; clay volume is calculated from the GR-log and water satuation from the cross-plottet porosity values and the deep resistivity log.
