Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A system for recovering heat in wellpad Steam Assisted Gravity Drainage (SAGD) steam generation, comprising: wellpads; at least one steam generator located at or near the wellpads, wherein feedwater is supplied to the steam generator; a produced fluids line conveying produced fluids from the well pad to pad separators, the pad separators located on the wellpads, each of the pad separators having an inlet, a gas outlet, and an emulsion outlet, wh…
