Gas Turbine Advantages Over Competition
High uptime modular power solutions for the oil & gas industry
Comparison to Competitors:
Flex
Gas Turbines
Diesel
Gensets
Gas-Fired
Recip Engine
Low annual maintenance (Very few “Touches”)
Ability to consistently absorb and shed large power loads
Robust oil lubricated bearings
Rugged synchronous generator can start 100 HP (GT250S) &
125 HP (GT333S) loads
Utilizes resistive load bank to manage highly transient loads
associated with artificial lift sites
Use of field gas vs. need to import more expensive fuel
(Diesel, LNG + transportation) AND eliminates expensive and
difficult fuel logistics in locations that have well/pipeline gas
Low emissions allows for easier permitting and ensures
emissions limits are not exceeded
20. 1. Increased production
• Low maintenance equals more uptime
• Better load handling means consistently higher uptime in real world applications
2. Decreased operating costs
• Eliminates need to buy expensive diesel fuel
• Fewer touches and less scheduled downtime than any recip engine
• Remote connectivity and monitoring enables data logging and diagnostics to be
done offsite
3. Reduced emissions
• Reduce / eliminate flaring
• Patented, ultra-lean combustion system that produces low emissions and enables
use in non-attainment areas
