Project overview

Quality Energy have been carrying out Power Quality improvements for the Oil & Gas sector for over 15 years, engineering energy efficiency and power quality projects in Africa, the Middle East, Asia and Australia. When Ensign Energy approached us to look over a very unique project that required more electrical energy than the drilling rig could produce in its current configuration , we were more than happy to assist.

A land rig owned and run by Ensign Energy was given the task of drilling a directional gas well which required more drilling power than the four generator sets (engine and alternator) installed on the rig could provide. When drilling at full electrical load, the rig’s electrical system was running with a power factor of between 0.40 and 0.50 inductive. This low power factor was limiting the drilling power potential of the rig. If this rig was to be used for the project at hand, the power factor had to be improved. Installing what would be such a large solution to an oil rig always has its challenges. Wiring in the necessary cabling and protection into the main switchboard was one challenge. Other hurdles included sourcing the correct electrical equipment in Australia given the rig runs at 600V 60 Hz and the control voltage runs at 110V.
The Problem
As a result of the rigs poor power factor, the gen-sets were not delivering as much power as they were capable of and our engineers identified the rigs optimal power factor of 0.7 was not being achieved. With their electrical system not performing at peak efficiency, Ensign Energy were looking to install another costly gen-set to deliver the required power to perform the job at hand. This would have required a huge infrastructure cost as well as the consideration of more fuel and maintenance, so they started to look for an alternative solution.
The Consequences
Over the years Quality Energy has worked on numerous projects in the Oil & Gas sector so we understand the nature of drilling rigs electrical systems. History has told us that these rigs typically run inefficiently and with the installation of our customised Power Factor Correction Units we could improve the rigs efficiency and deliver more power to where it is required. Our engineers calculated that a 2.88 MVAr capacitor bank would be required to improve the power factor to the gen-sets design requirement of 0.70 PF.

Project Outcomes

With their initial system, an additional gen-set would have been required to deliver the same amount of power as the optimised setup after the installation of our Power Factor Correction Units. The installation of the PFC Units was far more cost efficient than the purchase of a new gen-set and as a bonus it requires no additional fuel.

The Benefit
Now the rig is running closer to peak efficiency without the need to add more generation to perform the job at hand. It’s a win for Beach Energy, Ensign Energy and the environment.
