1. A computer-implemented method comprising: gathering sensor data regarding offset wells, based on measurements by one or more physical sensors associated with a drilling operation; gathering context data regarding the offset wells, the context data relating to aspects of the drilling operation that are not based on measurements by physical sensors associated with the drilling operation; placing the sensor data and the context data into a data store; creating a reduced data set by identifying a correlation between the sensor data and the context data in the data store, wherein the correlation is predictive of an operational outcome of the drilling operation, and the correlation is identified without preselected distance measures; creating a model based on the reduced data set; predicting the operational outcome based on the model; adjusting at least one drilling parameter for the drilling operation, based on the predicted operational outcome; and drilling a wellbore through a formation based on the at least one adjusted drilling parameter.
