Abstract: A distributed control system can be used to implement failover capabilities for control units that control well equipment during a well operation. For example, a system can include first well equipment that performs a first physical task and second well equipment that performs a second physical task different from the first physical task. Additionally, the system can include a distributed control system with a first control unit coupled to the first well equipment and a second control unit coupled to the second well equipment. Both control units may include a first control module and a second control module for automatically controlling the first physical task and the second physical task, respectively. The distributed control system can detect a failure of the second control unit and initiate a failover process in which the first control unit takes over control of the second physical task by enabling the second control module.

Abstract: A method of managing an influx encountered during a drilling operation conducted with respect to a wellbore includes drilling a wellbore into a subterranean formation. Drilling the wellbore includes circulating a drilling fluid through a wellbore while operating a drill bit and monitoring one or more parameters associated with the drilling operation for indicia of the influx within the wellbore. The method also includes, upon detecting the indicia of the influx, determining, via an influx management model, an initial influx volume.

Abstract: A centralizing perforating gun for perforating a tubular in a wellbore include a gun housing, perforating charges positioned within the gun housing and detonatable to perforate the tubular, and a centralizing system. The centralizing system includes an extendable member configured to move between a retracted position and an extended position. The extendable member is configured to engage a surface of the tubular in the extended position, thereby biasing the centralizing perforating gun away from the surface of the tubular.

Abstract: A perforating gun assembly for use within a borehole. The perforating gun assembly may include a first perforating charge section, a second perforating charge section, and a tandem coupling the first perforating charge section to the second perforating charge section. The tandem may include a first sensor package that may be operable to determine a flowrate of formation fluid flowing around the tandem and a second sensor package that may be operable to identify the formation fluid.

Abstract: A method and apparatus including a fluid pressure actuator that includes a diaphragm that has a top and a bottom surface. In an exemplary embodiment, the fluid pressure actuator also has plunger coupled to the diaphragm and that extends from the bottom surface of the diaphragm in a first direction. The fluid pressure actuator also includes a bellow sensor that is coupled to the bottom surface of the diaphragm and that has an interior surface. In an exemplary embodiment, a height of the interior surface of the bellow sensor prevents the movement of the plunger in the first direction.
