Abstract
Official abstract text for this publication.
Methods and systems are provided for enhancing heavy oil recovery using fixed-bed chemical looping combustion processes that incorporate carbon dioxide capture and/or sequestration. A fixed-bed chemical looping combustion process is provided for generating heat and carbon dioxide. The heat thus generated may be employed in thermal recovery techniques such as SAGD to enhance recovery of heavy oils. Additionally or alternatively, the carbon dioxide produced by the process may be sequestered, captured, employed as a tertiary recovery technique, or any combination thereof. Advantages of certain embodiments include one or more of the following advantages: lower cost, relatively high conversion rates, and high theoretical efficiency of carbon dioxide capture.
First claim
Opening claim text (preview).
What is claimed is: 1. A fixed-bed chemical looping combustion process for generating heat and carbon dioxide for enhanced oil recovery from a subterranean formation comprising the steps of: (a) providing a plurality of reactors, wherein each of the plurality of reactors comprises an oxygen carrier agent in a fixed bed, wherein the plurality of reactors comprise a first reactor and a second reactor, wherein the oxygen carrier agent of the first reactor is substantially depleted of…
