Classification: CPC G  E | IPC G

Claim 15:
16. A system comprising:
a processor;
memory accessible to the processor;
processor-executable instructions stored in the memory and executable by the processor to instruct the system to:
access data generated during field operations, wherein the data comprise structured data within database structures and unstructured data within digitally stored documents, and wherein the data comprise entity data for entities and field data from measurements;
apply deterministic rules to the data, wherein meeting a condition of one of the deterministic rules establishes a deterministic relationship for a portion of the data and associates a confidence score to the deterministic relationship;
discover probabilistic relationships for the data using the system, wherein the probabilistic relationships comprise descriptions generated through natural language processing of the structured data that describe relationships within the structured data and comprise descriptions generated through fact extraction from the unstructured data that describe relationships between extracted facts and portions of the structured data;
generate a data structure representable as a graph that comprises vertices and edges using at least a portion of the data, wherein each of the vertices represents one of the entities or one of the measurements, wherein the edges represent the relationships between the vertices, wherein one or more of the vertices positioned at a center of the graph are representative of one or more geological formations, and wherein the edges disposed radially from the center of the graph and connecting corresponding vertices are representative of different geological formations, wellheads, wellbores, well completions, formation tops, reports, and fluid volumes at different hierarchy levels; and
generate a query result using the data structure responsive to receipt of a query, wherein the query result depends at least in part on one or more of the descriptions that describe the relationships between the vertices.
