Temperature logs in an old brine-disposal well reveal a large thermal anomaly in and around the disposal aquifier. The shape and rate of decay of the anomaly permit comparison with a numerical model of the system, to give estimates of the initial amplitude of the anomaly and the rate at which the injected brine is being swept laterally from the injection zone centered on the well. It is found that the water in a portion of the Mannville Group near Regina is moving with a lateral flow rate of 2.6 m/yr, with a limit of probable error of 15%. It is not possible to determine the direction of movement by this method. The limited pressure date available suggest that flow of this rate may be greater than the mean regional flow.
