Filed: 2012-08-16
Abstract: A chemical composition and methods for use in the recovery of viscous oil and other desired hydrocarbons from subterranean reservoirs and from excavated material comprising oil sands or oil shale, and to remediate contaminated soil and subterranean reservoirs. Adding the composition to viscous oil renders it pipelineable by significantly reducing its viscosity. The chemical composition comprises an alkane, an ether, and an aromatic hydrocarbon. The composition is an organic solvent mixture that interacts highly favorably with non-polar hydrocarbons but is mostly immiscible with water and acts as a diluent, lowering the viscosity and raising the specific gravity of viscous oil. Additional water and heat are not required. Methods of using the composition in subterranean reservoirs and with excavated material including oil sands or oil shale and contaminated soil and subterranean reservoirs needing remediation, are highly efficient, economical, and reduce or eliminate adverse environmental consequences.

IPC: C10G1/04
Filed: 2011-03-15
Abstract: Methods are provided for enhancing recovery of heavy oil from oil sand reservoirs through the creation of subsurface high permeability pathways distributed throughout the oil sand reservoirs. The high permeability pathways may be boreholes that extend through the oil sand reservoir. A portion of the high permeability pathway may be packed with high permeability particulate to provide structural support and allow for high permeability throughout the boreholes. After establishing the high permeability pathways throughout the oil sand reservoir, solvent may be introduced into the oil sand reservoir. The solvent has the beneficial effect of lowering the viscosity of the heavy oil, which aids in the extraction of the heavy oil. Thermal recovery processes and other enhancements may be combined with these methods to aid in reducing the viscosity of the heavy oil. Advantages of these methods include, accelerated hydrocarbon recovery, higher production efficiencies, lower costs, and lower extraction times.

Abstract: A novel and powerful fluence and beam orientation optimization package for radiotherapy optimization, called PARETO (Pareto-Aware Radiotherapy Evolutionary Treatment Optimization), makes use of a multi-objective genetic algorithm capable of optimizing several objective functions simultaneously and mapping the structure of their trade-off surface efficiently and in detail. PARETO generates a database of Pareto non-dominated solutions and allows the graphical exploration of trade-offs between multiple planning objectives during IMRT treatment planning. PARETO offers automated and truly multi-objective treatment plan optimization, which does not require any objective weights to be chosen, and therefore finds a large sample of optimized solutions defining a trade-off surface, which represents the range of compromises that are possible.
