Abstract
A method of recovering heat from hot produced fluids at SAGD facilities is described that utilizes wellpad steam generation such as Direct Steam Generators (DSG). Heated fluids produced by SAGD are used to preheat the water that is used to make steam for SAGD. Feedwater is conveniently preheated at the wellpads by the produced fluids, emulsions, and/or gases before feeding to the DSGs.
