A method for formation pore pressure prediction involves obtaining an input parameter set while drilling a well. The input parameter set includes surface drilling parameters, logging while drilling parameters, and advanced mud gas measurements. The method further involves generating, from the input parameter set, a reduced input parameter set, by eliminating at least one input parameter of the input parameter set that is considered non-relevant for predicting the pore pressure, and predicting the pore pressure by applying a machine learning model to the reduced input parameter set.

There are described methods, systems, and techniques for performing automated drilling of a well bore. The well bore is drilled according to one or more drilling parameter targets associated with one or more corresponding drilling parameters. A controlling drilling parameter of the one or more drilling parameters is determined to be outside a threshold window. In response to determining that a stringer has been encountered, one or more controlled drilling parameter targets of the one or more drilling parameter targets are updated. The controlled drilling parameter targets comprise a revolutions per minute (RPM) target and weight-on-bit (WOB) target.

Systems and methods for monitoring equipment of multiple drill rigs. Each drill rig comprises multiple equipment units collectively operable to perform well construction operations to construct a well. An example monitoring system may be operable to receive operational data from each drill rig, determine operational status of each drill rig based at least partially on the operational data, and determine operational health indicators for each equipment unit of each drill rig based at least partially on the operational data. Each operational health indicator is indicative of operational health of a corresponding equipment unit with respect to a different operational health category. The monitoring system may be further operable to display the operational status for each drill rig, including the operational health indicators for each equipment unit of each drill rig, as a single page on a video output device.
