Abstract
A baffle apparatus and method for use in a well to mitigate convective in-well flow. The baffle apparatus includes a baffle member attached to a rod. The baffle member prevents vertical flow of water in the well after the baffle apparatus is deployed in the well. At least one centralizer is attached to the rod to maintain correct orientation of the baffle member within the well. The baffle member and the at least one centralizer allow well water to pass during deployment and recovery of the baffle apparatus.
