Abstract
A system and method for quantifying zonal flow in a multi-lateral well, including providing a first taggant through a first dosing tubing to a first lateral in a wellbore of the multi-lateral well, providing a second taggant through a second dosing tubing to a second lateral in the wellbore, flowing a first produced fluid from a subterranean formation via the first lateral into production tubing, flowing a second produced fluid including from the subterranean formation via the second lateral into the production tubing, flowing a produced stream including the first produced fluid and the second produced fluid uphole through the production tubing and discharging the produced stream from the wellbore, and analyzing the produced stream to measure an amount of the first taggant in the produced stream and an amount of the second taggant in the produced stream, wherein the first taggant and the second taggant are water soluble.
