A method and system of analyzing real-time drilling data to automate a drilling rig system for drilling a well. The method comprises: communicating, via a communication network, real-time data obtained from at least the drilling rig to a server to generate a data stream hosted on the server; monitoring, via a stream listener of an AI/ML software program hosted on a device, the data stream to detect an event; processing, via a processing engine of the AI/ML software, the real-time data relating to the detected event to generate processed data; inputting the processed data into an AI/ML module; generating, via the AI/ML module, an output, the output including a command to modify a drilling parameter of the drilling rig system; and implementing, via the output module of the AI/ML software, the command to modify the drilling parameter of the drilling rig system.

A pressure management device (PMD) for direct connection to a blowout preventor stack of a managed pressure drilling system, the PMD comprising a housing, one or more chokes, and a directional valve. The directional valve has a choke position and a bypass position. When the directional valve is in the choke position, the PMD operates to divert fluid entering the housing to one or more of the chokes. When the directional valve is in the bypass position, the PMD operates to divert fluid entering the housing to bypass the chokes. The inlet and outlet of each choke may be controlled by a dual shutoff valve, to selectively permit and restrict fluid flow through each choke.

A method for drilling a wellbore comprises using drilling mud having a mud weight less than the formation pore pressure while drilling the horizontal section, to release some formation gas to mix with the drilling mud. As the mixture flows up the wellbore annulus, the resulting pressure in the vertical section is within the mud weight window (MWW) of the weak zones, thereby maintaining wellbore stability without the need for intermediate casings. The wellbore is killed by introducing a volume of heavy mud via a circulation sub in the drill string and periodically introducing additional heavy mud to fill the void left behind by the drill string as it is pulled uphole. The ratio of light mud and heavy mud in the killed well is such that the resulting pressure in the vertical section is within the MWW of the weak zones.

A rotating control device wherein the bearing assembly can be secured to the bowl by rotationally coupling the bearing assembly with the bowl. When the bearing assembly is rotated in a first direction about a longitudinal axis relative to the bowl, an interlocking interface is formed between the inner surface of the bowl and the outer surface of the bearing assembly. The interlocking interface can be released by rotating the bearing assembly in a second direction relative to the bowl. The bowl comprises a rotary guide for engaging and rotating the bearing assembly. The rotary guide and the bearing assembly have an alignment profile for facilitating alignment of the bearing assembly with the bowl. The bearing assembly has a sealing element with axially extending fingers to provide internal structural support for the seal.

Choke controller, system, and method using adaptive proportional gain to control choke based on pressure setpoint
A controller and related system and method for controlling a choke for choking fluid flow are configured to take into account non-linear behaviors of the choke, to allow more accurate and effective control of the choke. To obtain a desired pressure drop across a choke valve, the controller is configured to monitor the position of a choke actuator coupled to the choke valve and the pressure at the inlet of the choke valve. The controller calculates an adaptive proportional gain coefficient, and optionally adaptive integral and derivative coefficients, based on the choke actuator position, to help mitigate the effects of non-linear behaviors of the choke and, where necessary, based on the inlet pressure, the controller calculates an augmentation correction to address any instability in the choke. The controller then commands the choke actuator accordingly to adjust the flow area through the choke valve.
