Abstract
Official abstract text for this publication.
Heavy oil recovery from oil sand reservoirs is enhanced 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for enhancing recovery of bitumen from a thin reservoir comprising the steps of: establishing a distribution of high permeability pathways in a thin reservoir wherein the step of establishing comprises drilling a plurality of boreholes through the thin reservoir, each borehole having a diameter and each borehole being an openhole, wherein the thin reservoir is nonconsolidated and wherein the thin reservoir has a thickness of less than or equal to ab…
