Power System Automation Drives Costs Down at North American Well Sites
Forrest Marsh January, 2017
Bringing down the associated costs of Diesel Power Generation Systems: • Power Automation • Power on Demand
How can Power Generation be part of today’s discussion?
Evaluating Power Options
Utility Power
Diesel Power Automation
Diesel-Fired
Diesel Power on Demand
Gas-Fired LOW TOTAL POWERCOST
HIGH TOTAL POWER COST
LOW EMISSIONS
HIGH EMISSIONS
NG Power Automation
Tier 4 Diesel
Intermittent Remote Applications
Generators typically run 24/7, regardless of whether the operations are automated.
• High diesel fuel usage and costs • Excessive emissions • Frequent outages due to service and maintenance • More failures due to lengthy idle times • Faster depreciation of gensets
How can Power Automation be achieved?
• Hybrid Battery Control kit receives signals from PLC, tank level switch, or other digital switch
• Allowing for start/stop synchronization for power systems
• Effectively eliminating engine idling • Batteries provide secondary power for control panels when
power generation systems are not running.
Quickly Visualized: Power Automation for Rod Pumps
• ANIMATION PLAYS for Power Automation on Rod Pumps • (~1 min)
• Major producer in the Permian Basin • 5 single well pads with intermittent 40HP rod pumps, ~12 hrs/day • Diesel generators were running or idling 24/7
– Idle 50% of the time
• H2S treatment was cost prohibitive for gas fired power generation in this scenario
• Producer needed to maintain production while lowering LOE’s
Case Study: Power Automation for Rod Pumps
• The Solution: – Five (5) diesel power systems equipped with hybrid battery
kits were sized for the 5 well-pads – Power systems were in operation only when the pump was
“ON” – engine idling was eliminated – $13,000 per pump in fuel costs were saved over 6 months
• $130,000 annualized savings for 5 pumps – Emissions were reduced more than 50% – Maximized uptime by minimizing service & maintenance
interruptions

Case Study: Power Automation for Booster Pumps
• Midstream company in the Permian Basin • 200hp booster pump at a transfer facility
– Pump only runs 10% of the time • Previous diesel generator was running 24/7
– Engine idled 90% of the time • Field gas was not available as a fuel source • Producer needed to maintain production while lowering LOE’s
Case Study: Power Automation for Booster Pumps
• The Solution: – Power generation system for the remote operation was sized for
the application – Power automation kit – 24/7 Aggreko Remote Monitoring (ARM) – Power generation system was in operation only when the pump
was “ON” – engine idling was eliminated – Eliminated 21 hours of idle time per day – 60% savings on diesel costs, $16,000 annualized – 60% improvement in emissions
So what is Power on Demand?
• Using the same automation kits, the ability to intelligently start/stop multiple generators in any combination to meet fluctuations in load demand.
Case Study: Power on Demand: Remote Start/Stop
Major producer wanted the ability to remotely start/stop NGL pumps and generators located in WY from their control center in Tulsa, OK. • The Solution
– Power on Demand Package – 10 Tier 4 Generators (seven 200kW, three 300kW) – Step up transformer from 480V to 4160V – SCADA software interfaced PLC and power automation kit – 24/7 Live Remote Monitoring Services in New Iberia
• The Value/Benefits – Producer is able to remotely start/stop any combination of
generators to balance NGL pump load demand and save fuel.
Power on Demand on a smaller scale: Booster Stations
Dual 200kW Tier 4 generators operating in parallel

Automated, intelligent power systems are the next step for progress towards fully automated oilfield operations.
Power System Automation Drives Down Costs for Upstream and Midstream O&G
1. Proven to reduce fuel costs by 30-63%
2. Emissions are reduced between 30-63%
3. Maximize uptime by eliminating failures associated with idling
