Real-Time Risk Prediction During Drilling Operations

摘要

Systems and methods for real-time risk prediction during drilling operations using real-time data from an uncompleted well, a trained coarse layer model and a trained fine layer model for each respective layer of the trained coarse layer model. In addition to using the systems and methods for real-time risk prediction, the systems and methods may also be used to monitor other uncompleted wells and to perform a statistical analysis of the duration of each risk level for the monitored well.

主权项

1. A method for managing a predetermined risk during drilling operations of a well, which comprises:
providing a graphical user interface for displaying i) each prediction of the predetermined risk in one of a plurality of risk zones, each risk zone being associated with a predetermined incremental time and level of risk, at a predetermined warning interval during the drilling operations; and ii) a predetermined suggestion for modifying the drilling operations based on one of the predictions of the predetermined risk; monitoring each prediction of the predetermined risk at the predetermined warning interval during the drilling operations using the graphical user interface and a computer processor; and managing the predetermined risk during the drilling operations by using the predetermined suggestion to modify the drilling operations and lower the level of risk for another one of the predictions of the predetermined risk in one of the plurality of risk zones during the drilling operations.
