Automated control system integrates preventive and predictive maintenance functions

Integrated Drilling Equipment (IDE) has introduced the second-generation, automated Centurion drilling control system on a new 1,500-hp AC Sparta rig for Lewis Energy in the Eagle Ford Shale.
The new system, developed by IDE’s Automation and Controls division, combines preventive and predictive maintenance functions, such as coriolis flow meters, to measure real-time drilling fluid density, mass flow and temperature and pressure readings. It is designed in an open architecture software platform to deliver real-time information and control to drilling contractors, operators and service companies.
“Using this type of platform enables service companies to employ specialized applications for control of the auto-driller and pressure control aspects of rigs,” IDE CEO Steve Cope said. “The use of customer-supplied applications allows for optimal rate of penetration while maintaining zone management and the safety of personnel and machinery.”
The software technology used with the Centurion system also eliminates the need for customers to learn another interface, he added. Information can be accessed onsite and offsite via the internet or by using a personal computer, smartphone or tablet.
“With this system, we’re taking existing technology and implementing it in a new way on land-based rigs to increase efficiency, accuracy and predictability,” said Charlie Piper, IDE vice president of technical products. “For example, the system can perform oil analysis to give us the real-time properties or viscosity of the diesel powering the rig so we know how much life is left in the diesel before it needs to be changed,” he said. Data from the new system to better understand the trigger points for preventive maintenance and measure the system’s economic viability is being collected and analyzed at 60- and 90-day intervals.
The Centurion system package for the Lewis rig is outfitted with a full package of options, including an integrated, self-aligning satellite system with high-speed broadband; offsite access to all systems; full communication systems with voice over IP; telephone; IP camera and DVR system; fire and gas detection; real-time logging, and offsite data collection and reporting. “By using our own satellite system, we are able to collect and aggregate the data and transfer it quickly to our monitoring facility,” Mr Piper added.
The Sparta Drilling System, one of IDE’s engineered rig packages offered in 500-kip, 750-kip and 1,000-kip (a kip is 1,000 lbs of force) load ratings, features a modular self-elevating mast and a substructure with an integrated walking system. It is designed to be fast-moving for efficient rig moves from pad to pad and well to well. The rig also features the latest AC variable frequency drive technology, proprietary drilling controls and automated options.
