Nabors develops optimization features for the drilling engine management system

As efforts to decarbonize operations and reduce fuel consumption and costs have accelerated, the industry has focused on optimizing engine utilization as an efficient way to achieve these goals. Reducing average engine usage saves fuel and reduces emissions.

Deployable on Nabors rigs and beyond for the wider drilling community, the SmartPOWER™ drill motor management system has been developed with two main configurations: advisory and control. The advisory solution sends automated alerts to the driller via HMI screens as to the optimal number of drill motors to run. The control function automates the starting and stopping of motors based on these advisories.

Live Electronic Drill Recorder (EDR) data

With a 10-minute preview, Nabors’ solution uses AI to analyze live EDR data from RigCLOUD®, or other drilling data systems, to forecast energy requirements for upcoming drilling activities and identifies the optimum number of motors for the required power demand.

Downgrade module

Another feature is Nabors AI-based engine derating module. Proprietary technology evaluates each engine’s life, altitude, coolant temperature, oil and filter condition and other factors to gauge available power capacity based on its conditions specific. Knowing which motors to run is just as important as knowing how many motors to run to meet the power demand.

Longer term, Nabors plans to use this data as part of its Equipment Condition Monitoring (ECM) solution, streamlining maintenance and improving service performance.

Engine controls

SmartPOWER™ is fully automatable. By connecting to a rig’s generator control system, motors are automatically turned on or off based on notices.

Available for the entire drilling community

SmartPOWER™ can be deployed across the Nabors fleet and beyond to other drilling contractors via RigCLOUD® and Canrig.

Case study

Field testing of the advisory system, conducted on a Nabors rig in Q1 2022, indicated an in-house diesel consumption reduction of up to 20% in some applications, with an equivalent reduction in CO2 emissions. This reduction is relative to the baseline established from the average fuel consumed during operations with all engines available, without manual intervention of the generators. To enable a true comparison, the kilowatt-hours generated are compared to the fuel actually consumed, creating a comparison that is independent of drilling activity and accurate to true fuel consumption for a given level of power generation.

Luke Trueheart, Product Line Manager, said: “What makes SmartPOWER particularly unique is that we are the first to analyze live EDR data and use our proprietary engine derating module to provide feedback. more precise and efficient motors. Our AI-based system is a powerful tool for drilling contractors looking to reduce emissions and fuel consumption. »
