Abstract

TECHNIQUES FOR REDUCED CONTAMINATION FORMATION EVALUATION ARE PROVIDED. THE TECHNIQUES RELATE TO DRAWING FLUID INTO A DOWNHOLE TOOL (10) POSITIONABLE IN A WELLBORE (14) PENETRATING A SUBTERRANEAN FORMATION (F) HAVING A VIRGIN FLUID AND A CONTAMINATED FLUID THEREIN. FLUID IS DRAWN INTO AT LEAST TWO INLETS FOR RECEIVING THE FLUIDS FROM THE FORMATION (F). AT LEAST ONE EVALUATION FLOWLINE (28) IS FLUIDLY CONNECTED TO AT LEAST ONE OF THE INLETS FOR PASSAGE OF THE VIRGIN FLUID INTO THE DOWNHOLE TOOL (10). AT LEAST ONE CLEANUP FLOWLINE (30) IS FLUIDLY CONNECTED TO THE INLETS FOR PASSAGE OF THE CONTAMINATED FLUID INTO THE DOWNHOLE TOOL (10). AT LEAST ONE FLUID CIRCUIT IS FLUIDLY CONNECTED TO. THE EVALUATION FLOWLINE AND/OR CLEANUP FLOWLINES (28, 30) FOR SELECTIVELY DRAWING FLUID THEREIN. AT LEAST ONE FLUID CONNECTOR (48) IS PROVIDED FOR SELECTIVELY ESTABLISHING A FLUID CONNECTION BETWEEN THE FLOWLINES (28, 30). AT LEAST ONE SENSOR IS PROVIDED FOR MEASURING DOWNHOLE PARAMETERS IN ONE OF THE FLOWLINES (28, 30). FLUID MAY BE SELECTIVELY PUMPED THROUGH THE FLOWLINES TO REDUCE THE CONTAMINATION IN THE EVALUATION FLOWLINE (28).FIG. 3
