Although river-channel reservoirs are attractive because of their potential high porosity and permeability, their development is difficult because of rapid variations in the distribution of sands and shales. The Taber-Turin area of Alberta, Canada is a known oil province characterized by such reservoirs. To delineate potential reservoirs in detail, a 4 -km 3-d seismic survey was conducted, resulting in a square grid with traces 20-m apart. The Seismic Lithologic Modeling (SLIM™) process, an automated procedure that refines initial geologic models, was then applied to provide a thin-layer interpretation of the processed data. Although the initial model for the SLIM process was based on information from only one borehole (primarily for calibration purposes), the derived velocity model revealed, in detail, the thin Glauconitic reservoirs (0-30 m thick) that are the targets of the delineation effort. All six boreholes previously drilled in the area, four of them producers and two dry, are consistent with the SLIM interpretation. With the help of the SLIM results, three additional boreholes were proposed. To date, two of them have been completed, and both are oil producers.
