Abstract

A method for drilling a well includes prescribing a drill recipe with a drill analysis engine based on a field-specific model. The drill recipe identifies prescribed segments, mud flow parameters, and drill parameters. Each prescribed segment of the prescribed segments includes a start depth. The method further includes initiating drilling of the well based on the drill recipe; receiving a drill log in narrative text format; detecting a drill event inconsistent with the drill recipe by analyzing the drill log with a log analysis engine; prescribing an adjusted drill recipe with the drill analysis engine based on the field-specific model in response to the drill event, the adjusted drill recipe including adjusted prescribed segments; and drilling the well based on the adjusted drill recipe.

Claims

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.
