Abstract
A method can include, responsive to receipt of a search instruction that includes one or more search criteria, accessing a data structure for subsurface geologic regions categorized at least in part according to parameters that describe depositional environments, where the data structure includes one or more includes virtual distances between the parameters; generating a search result using the one or more search criteria and the data structure, where the search result represents an organization of at least a portion of subsurface geologic regions as closest analogues to the one or more search criteria; and transmitting search result information for graphically rendering the search result to a display as part of an interactive graphical user interface.

A method comprising:
- responsive to receipt of a search instruction that comprises one or more search criteria representative of an analogue for a subsurface geologic region, accessing a data structure for subsurface geologic regions categorized at least in part according to parameters that describe lithological properties of depositional environments, wherein the data structure is generated using a machine learning model configured to generate clusters of nodes based on lithological data, wherein the clusters of nodes correspond to the parameters, wherein the parameters correspond to porosity, permeability, pore pressure, or any combination thereof, wherein the data structure comprises virtual distances between the parameters, and wherein each of the virtual distances corresponds to:
- an amount of similarity between respective parameters;
- and
- a Fibonacci number;
- generating a search result using the one or more search criteria, the data structure, and the virtual distances, wherein the search result represents an organization of at least a portion of the subsurface geologic regions as closest analogues to the one or more search criteria;
- transmitting the search result for graphically rendering the search result to a display as part of an interactive graphical user interface;
- determining whether a prospect is present in the subsurface geologic region based on the search result, wherein the prospect corresponds to a reservoir;
- and
- based on the determining,
