1. A method, comprising:
- receiving a set of unstructured historic drill reports, the unstructured historic drill reports including multiple acronyms and/or abbreviations relating to a single drilling factor;
transforming the unstructured historic drill reports into structured historic drill reports;
based on the structured historic drill reports, building a plurality of field-specific models, each of the plurality of field-specific models being specific to a field having geological, geophysical, petrophysical, lithological, and/or mineralogical characteristics, wherein each of the plurality of field-specific models includes a proximity depletion variable derived from, at least, distances from a well to adjacent wells and associated depletion curves;
determining a test set of information from one or more additional historic drill reports, and validating each of the plurality of field-specific models using the test set of information;
based on results of the validation, selecting one of the plurality of field-specific models;
prescribing, using an analysis engine and based on the selected field-specific model, a drill recipe for the well;
drilling a portion of the well in accordance with the drill recipe;
receiving an unstructured drill report associated with the well;
transforming the unstructured drill report associated with the well into a structured drill report associated with the well;
determining, using the analysis engine and based on the selected field-specific model and further based on the structured drill report associated with the well, a drill event for the well and a depth associated with the drill event;
prescribing, using the analysis engine and based on the selected field-specific model and further based on the drill event and the depth associated with the drill event, an updated drill recipe for the well; and
drilling another portion of the well in accordance with the updated drill recipe.

Abstract
A method for determining a drill event includes receiving a set of historic drill reports with annotations. The historic drill reports include a plurality of entries including multiple acronyms relating to a single drilling factor. A set of entries of the plurality of entries indicates an associated depth. The method further includes training a report analysis engine utilizing the historic drill reports and annotations; receiving a drill report associated with a well; and determining a drill event and associated depth utilizing the report analysis engine applied to the drill report.
