1. A method for drilling a well, the method comprising:

  • receiving information associated with one or more producing wells in a field, the field having field characteristics including geological, geophysical, petrophysical, lithological, and mineralogical characteristics, a first portion of the field information being received in a form of structured data, and a second portion of the field information being received in a form of unstructured data;

    transforming the unstructured data into transformed structured data;

    based on the received field information in the form of the structured data and the transformed structured data, building a plurality of field-specific models, each of the plurality of field-specific models being specific to the field characteristics of the field;

    receiving information associated with a further one or more wells in the field;

    determining a test set of information from the received information associated with the further one or more wells in the field, 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 a drill analysis engine and based on the selected field-specific model, a drill recipe, the drill recipe identifying prescribed segments, mud flow parameters, and drill parameters, each prescribed segment of the prescribed segments including a start depth;

    initiating drilling of the well based on the drill recipe;

    receiving a drill log generated during drilling of the well in narrative text format;

    detecting a drill event inconsistent with the drill recipe by analyzing the drill log;

    prescribing, using the drill analysis engine and based on the selected field-specific model, an adjusted drill recipe in response to the drill event, the adjusted drill recipe including adjusted prescribed segments; and

    drilling the well based on the adjusted drill recipe.
