Scarcity of conventional oil reserves amidst increasing liquid fuel demand in the world have renewed interest in oil shale processing because of the massive accessible resources. In-situ oil shale production has a lessened environmental impact, and likely lower cost than mining and surface processing. A few current processing strategies are briefly described. Heat transfer pathways, chemical kinetics, geomechanics, multiphase fluid flow, and process strategies all provide complexities to any in-situ oil shale production strategy. Understanding each of these phenomena, and appropriate model coupling is necessary to accurately model in-situ oil shale production processes. Results from in-situ oil shale modeling with the STARS simulator by the Computer Modeling Group (CMG) are discussed. Idealized energy efficiency and carbon footprint for this type of process were estimated as 3:1 net energy gain and 36 kg CO 2 /bbl oil produced respectively. |
