1. n. [Reservoir Characterization]

The act of determining values for grid elements on a map. The grid element values are chosen from nearby data points. Methods are deterministic and use linear and nonlinear interpolation methods, or may be statistical and use geostatistical approaches such as kriging. Gridding is usually applied to one characteristic per map, such as structure, thickness, porosity, permeability or saturation.
