A well construction system having well construction equipment operable to perform well construction operations to drill a well, power equipment operable to supply electrical power to the well construction equipment via an electrical power bus, operational data sources operable to output operational data, and a power manager communicatively connected with the operational data sources and the power equipment. The operational data sources may include sensors associated with at least one of the well construction equipment, the power equipment, and the electrical power bus. The power manager receives the operational data and outputs power control data to the power equipment to control the electrical power being supplied by the power equipment to the well construction equipment via the electrical power bus during the well construction operations based on the operational data.

Power management at a wellsite

An example well construction system includes well construction equipment, a power supply system, and a control system. The well construction equipment performs well construction operations. The power supply system outputs electrical power to the well construction equipment. The power supply system includes an electrical generator unit and a control system including a processor and a memory storing a computer program code. The computer program code causes the control system to control an electrical power output level of the power supply system during the well construction operations. The computer program code also causes the control system to control operation of the well construction equipment during the well construction operations based on the electrical power output level during the well construction operations and an electrical power demand level of the well construction equipment during the well construction operations.

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

Systems and methods for managing power at a wellsite. A system includes well construction equipment, power equipment, a power manager, power equipment sensors operable to output power equipment sensor data indicative of operational status of the power equipment, and a human-machine interface usable by a human user to enter power management settings. The power manager is operable to receive the power equipment sensor data and receive the power management settings, wherein each power management setting is associated with a corresponding mode of operation of the power manager. The power manager is further operable to, for each power management setting, change the mode of operation of the power manager to the mode of operation associated with that power management setting, and for each mode of operation, cause the power equipment to supply electrical power to the well construction equipment in a predetermined manner with respect to that mode of operation.

A well construction system having well construction equipment operable to perform well construction operations to drill a well, power equipment operable to supply electrical power to the well construction equipment via an electrical power bus, operational data sources operable to output operational data, and a power manager communicatively connected with the operational data sources and the power equipment. The operational data sources may include well construction equipment sensors, power equipment sensors, and an electrical power bus sensor. The power manager receives the operational data and outputs power control data to the power equipment to control the electrical power being supplied by the power equipment to the well construction equipment via the electrical power bus during the well construction operations based on the operational data.

A system may include a top drive coupled to a mast on a drilling rig. Additionally, a common bus may be coupled to the top drive. A drawworks may be coupled to the common bus and the top drive, and the drawworks lowers and raises the top drive throughout the mast. A generator may be coupled to the common bus, and the generator transmits electric power to the drawworks. Further, a controller may be coupled to the top drive, common bus, the generator, and the drawworks. The common bus may transmit the electric power between the top drive, drawworks, and the generator. The controller may manage a transmission of stored power in the top drive to the drawworks.
