Abstract: Systems and methods include a computer-implemented method for determining and storing a length scale dimension in spatial coordinate systems. A mapping of three-dimensional (3D) grid locations (x,y,z) relative to a continuous surface of the Earth is determined. The 3D grid locations have a grid point spacing in an (x,y) space defining map view coordinates of the continuous surface independent of an elevation z. A length scale (l) is determined for each 3D location. The length scale defines a 3D distance between 3D grid locations, and also defines a structural or geometrical length scale at the 3D location relevant to a given task. Then, (x,y,z,l) information is stored for each 3D grid location. The (x,y,z,l) information defines, for each (x,y) coordinate, a z-coordinate defining an elevation of the continuous surface at the (x,y) coordinate and the local length scale at the (x,y,z) coordinate.

A compositional coverage of the different analytical speciation techniques for the petroleum samples is determined using the different boiling curves. Each of the different analytical speciation techniques covers a different boiling range and produces a compositional model modeling a breakdown of components in the petroleum sample by carbon number, aromatic ring family, and heteroatom class.
