Abstract
A method includes receiving first fluid property data from a sample flowline of a focused sampling system and receiving second fluid property data from a guard flowline of the focused sampling system. The sample flowline and the guard flowline are each configured to sample formation fluid from a hydrocarbon reservoir, the formation fluid includes native formation fluid and a contaminant, and the first fluid property data includes an optical density of the native formation fluid and the second fluid property data includes an optical density of the contaminant
