Apparatus and methods for automating well construction operations based on detected abnormal events. A method may comprise commencing operation of an equipment controller of a control system for monitoring and controlling a well construction system. The well construction system may comprise well construction equipment operable to perform well construction operations. Commencing operation of the equipment controller may cause the equipment controller to receive sensor data from a sensor, detect an abnormal downhole event based on the sensor data, select an operational sequence to be performed by the well construction equipment based on the abnormal downhole event, and output control data to cause the well construction equipment to perform the operational sequence thereby mitigating the abnormal downhole event.

Apparatus and methods regarding a first processing system operable to receive a job plan developed by a second processing system, and implement the job plan, including generating commands for an equipment controller based on the job plan. The first processing system is operable to transmit, through a network, the commands to the controller for execution by the controller. The first processing system is operable to iteratively (i) monitor, through the network, current conditions of the well construction system during execution of commands by the controller; (ii) update the implementation of the job plan, including generating updated commands for the controller based on the job plan and the current well construction system conditions when the current well construction system conditions indicate a deviation from the implementation; and (iii) transmit, through the network, the updated commands to the controller for execution by the controller.

Well construction communication and control

A supervisory control system for a well construction rig operable to perform well construction operations to construct a planned well at a wellsite. The supervisory control system may be installable in association with the well construction rig. The supervisory control system may comprise a supervisory controller communicatively connectable with a central controller of a rig control system of the well construction rig. The rig control system may be communicatively connected with and operable to control well construction equipment of the well construction rig. The supervisory controller may be operable to control the well construction equipment via the rig control system to cause the well construction equipment to perform the well construction operations. The central controller may be operable as an I/O interface for matching inputs and outputs of the supervisory controller with corresponding inputs and outputs of at least one piece of the well construction equipment.

Supervisory control system for a well construction rig

A monitoring system for determining a stickup height of a drill string. The monitoring system includes a video camera operable to facilitate a digital image, a block position sensor operable to facilitate block position measurements, and/or a processing device. The processing device receives the digital image, recognizes an upper end of the drill string or a connection joint of the drill string on the digital image, and determines the stickup height based on location of the upper end of the drill string or the connection joint of the drill string on the digital image. The processing device may also or instead record a pipe tally indicative of a length of each drill pipe and a location of each drill pipe within the drill string, receive the block position measurements, and determine the stickup height based on the pipe tally and block position measurements.
