Abstract: A set of alarm criteria for a drilling tool may be obtained. Individual alarm criterion of the set of alarm criteria may be satisfied based on the drilling tool operating with a set of operating characteristics corresponding to the individual alarm criterion. The set of alarm criteria may include two or more of a tight-hole alarm criterion, a washout alarm criterion, a packoff alarm criterion, a weight-stacking alarm criterion, a delta-torque alarm criterion, a torque alarm criterion, a rate-of-penetration alarm criterion, a reamer-tension-compression alarm criterion, a running-speed alarm criterion, a drag alarm criterion, and/or a pipe-movement alarm criterion. An alarm event corresponding to an alarm criterion may be detected based on the operating characteristic(s) of the drilling tool matching the set of operating characteristics corresponding to the alarm criterion. Responsive to detection of the alarm event, an alarm for the alarm event may be generated.

Abstract: Methods, systems, and storage media for remote monitoring of a system usable in a subsurface volume of interest are disclosed. Exemplary implementations may: obtain system data for the system usable in the subsurface volume of interest; identify multiple alert times specifying multiple time values corresponding to a time interval where the multiple parameter values exceed a threshold range; generate a representation of the subsurface system using visual effects to depict at least a portion of the system data and at least a portion of the multiple alert times; and display the representation.
