Well drilling methods with automated response to event detection
First Claim
1. A well drilling method for drilling a well, comprising:
- monitoring a drilling parameter during drilling;
generating a parameter signature based on how the drilling parameter changes over time;
comparing the parameter signature to an event signature indicative of a drilling event;
detecting the drilling event will occur if the parameter signature is a partial match with the event signature; and
automatically controlling a drilling operation in response to the detecting.

Abstract
A well drilling method can include detecting a drilling event by comparing a parameter signature generated during drilling to an event signature indicative of the drilling event, and automatically controlling a drilling operation in response to at least a partial match resulting from comparing the parameter signature to the event signature. A well drilling system can include a control system which compares a parameter signature for a drilling operation to an event signature indicative of a drilling event, and a controller which controls the drilling operation automatically in response to the drilling event being indicated by at least a partial match between the parameter signature and the event signature.

30. A well drilling system for drilling a well, comprising:
-
a control system configured to monitor a drilling parameter during drilling and generate a parameter signature based on how the drilling parameter changes over time; the control system further configured to compare the parameter signature to an event signature indicative of a drilling event; the control system further configured to detect that the drilling event will occur if the parameter signature is a partial match with the event signature; and a controller configured to automatically control a drilling operation in response to detecting that the drilling event will occur. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)
