System and method for operational management of a guarded probe for formation fluid sampling

A system for managing sampling of formation fluids from an earth formation surrounding a wellbore using a guarded sampling probe, comprising:

• a wellbore tool configured for to be manipulated inside the wellbore;
• a guarded sampling probe coupled with the wellbore tool and configured for withdrawing fluids from the formation, wherein the guarded sampling probe comprises a sampling probe and a guard probe, and wherein the guarded probe is configured to draw wellbore fluids away from the sampling probe;
• a single flow line coupled with the sampling probe and the guard probe;
• a sensor configured to measure a property of the fluids withdrawn by the guarded sampling probe;
• and
• a processor coupled with the sensor and configured to split the single flowline into a guard flowline and a sample flowline, wherein the guard flowline is coupled with the guard probe and the sample flowline is coupled with the sampling probe.
