A method may include obtaining, from a digital drilling program and by a drilling management network, a drilling operation sequence of the drilling rig. The drilling management network is coupled to a drilling rig, rig equipment, and various electric power generators. The method may further include determining, by the drilling management network, a power management sequence that matches an electric power capacity of the drilling rig to an electric power consumption of the rig equipment. The method may further include executing, by the drilling management network, the power management sequence to the rig equipment and the electric power generators.

Intelligent power management system

Methods, apparatus, and products for receiving measurements indicative of present value torque (TrqPv) currently being applied by a top drive to a drill string extending in a well that penetrates a subterranean formation, and releasing torque accumulated in the drill string by determining polarity of TrqPv and, in response to a manual or automatic trigger, causing the top drive to perform an unwinding operation in a direction opposite to the determined TrqPv polarity.

Automatically detecting and unwinding accumulated drill string torque

Systems and methods for supplementing power to a drilling operation's generator and motor systems are disclosed. A power unit is connected to a power grid between generators and motors for a drilling operation. The power unit saps and stores energy from the electrical grid when the generator has excess capacity and providing power to the motors when the demand from the motors exceeds the available capacity of the generators.

Supplemental power unit for drilling rig

Systems and methods for operating a series of generators configured to provide power to a motor or motors. Generators generally operate at different efficiency levels depending on the operating capacity. A computation component can analyze the current efficiency of the generators and determine if there is an alternative power distribution among the existing generators that would result in a more efficient operation of the system.

Load management algorithm for optimizing engine efficiency

Systems and methods for operating a motor according to parameters provided by an autotuning component if available are described. A controller can be coupled to a drive which operates a motor for executing a task that can be related to a drilling operation for oil and gas. The controller stores initial parameters and checks for new parameters provided by the autotuning component which are stored on the drive after the autotuning component autotunes the motor. If there are new parameters, they are given priority over the initial parameters.

Systems and methods for managing drive parameters after maintenance

Systems and methods for controlling a drilling rig are disclosed herein. A driller can select between modes: local, human-machine interface (HMI), and automatic. In a local mode a motor operator is instructed to operate a genset for the drilling rig. In a Remote mode the driller can operate the genset directly without the need for a motor operator to start or stop the gensets. In an automatic mode, the genset is controlled according to a well plan including a power consumption schedule.
