This paper presents an observation over a suggested approaeh for establishing watersaturation model that is specifically designed -\vithout the need of resistivity log data. Oneof the main strength of the approaeh is that the resulting \vater saturation model ean bespecifically established for loeal or specific use only. This is true sinee the approaeh eanbe applied using earbonate roeks that are obtained locally or from specific areas. Anotherimportant eonelusion is that this approaeh ean also be applied for any earbonate roekclassification as long as the classification ean clearly group earbonate roeks into groupsyvith distinctive petrophysical properties. This paper — first part of two — presents theoryand roek classification that underlines the approaeh, as well as proeedure and the existingmodels available.
