Automated geo-target and geo-hazard notifications for drilling systems

Abstract

A drilling management system can monitor the traversed path of a drill bit throughout active drilling at a drilling site and notify appropriate team members regarding a current status of the active drilling in real-time. For example, the drilling management system can notify team members when predetermined milestones have been met, when the drill bit is drifting off course from a target wellbore trajectory from a target horizon or target zone, or when the drill bit is in danger of running into a geo-hazard, such as a pre-existing wellbore, unpierced fault plane, lease boundary, etc. The drilling management system can maintain a depth model of the drilling site that identifies the target wellbore trajectory, a target zone based on one or more horizons from the depth model, and coordinates of known geo-hazards at the drilling sites. The drilling management system can also maintain a set of rules for each of the drilling sites that indicates when team members should be notified.
