Abstract:
1. A computer-implemented method of locating resources in a reservoir, the reservoir including at least one injection well and at least one production well, comprising: defining discrete points in a reservoir; defining a region of interest in the reservoir; mapping a modeled permeability characteristic of structures comprising the reservoir; computing, via a computer, based on the modeled permeability characteristic, an indicator of time of flight for streamlines from each production well to each point; computing, via a computer, based on the modeled permeability characteristic, an indicator of time of flight for streamlines from each injection well to each point; combining, via a computer, the indicators of time of flight from each production well and each injection well to characterize a sweep efficiency of the reservoir wherein combining comprises combining the production well and injection well indicators of time of flight at each point within the region of interest of the reservoir; mapping, via a computer, the combined indicators of time of flight for the region of interest; displaying, via a computer, the mapped indicators of time of flight using a color scale, wherein the color scale provides a visual identification of areas of the reservoir that are likely to include bypassed resources; and identifying areas of high time of flight as the areas of the reservoir that are likely to include bypassed hydrocarbons in the reservoir.
