Green Field Energy Services – TF- 40 Turbine

Only weighs about 800 lbs.


Green Field Energy Services – Turbine Frac Pump (TFP)

Description TFP Diesel Frac Comments

Size – Single Frac 8’ x 9’ x 11’ 40’ – 45’ Trailer The TFP unit can fit two on a trailer with a full control house. Three per trailer without a control house.

Weight – Single Frac 32,000 lbs. 65,000 lbs +/- Weights are w/o trailer. GFES’s frac unit is road legal with two on a trailer.

Exhaust Heat Massive exhaust heat available

No waste heat available

The turbine produces 27 lbs/sec of 1,000 F heat. Use for process work, fuel heating, including well water evaporation.

Portability Chopper, air cargo and highway Highway The TFP frac is manufactured with forklift pockets and is light

enough for air transport .

Multi-Fuel CapabilityBio-fuel, diesel #2, kerosene , natural

gas or Jet A Diesel #2 Natural Gas is a proven fuel source for the TFP.

Emissions 75 – 85% Lower Higher emissions The TFP was certified on #2 diesel and B-100 bio-fuel. The TFP was 75% - 85% lower Nox and CO than a diesel.

Maintenance Easy PM’s and

same day exchanges

Higher labor hours The turbine only weighs 770 lbs – PM’s only take 4 hours –Field repairs and engine exchanges done on one shift.

Operating life 10,000 hours TBO Life is reduced when running at max power

The turbine has fewer moving parts - designed for harsh military duty and high cycles. Overhaul @ 10,000 hours +/-.

Noise Level 78 – 91 DBA No sound attenuation Two TFPs were measured on one trailer with all equipment running (14 bpm @ 9000 psi).

High Altitude Power Excess power available

Cannot achieve rated power

The 3800 turbine has power to spare to meet pump demand when at high altitude.

TFP Noise Attenuation

• Noise reduced by 10 dBA.

• Deflects noise upward.

• Less hearing protection.

• Eliminates sound walls in residential areas.

Our “Gasification” Initiative

• Can run on Natural Gas NOW!

– Going to Diesel was the hard part.

– Moving “back to gas” is simple.

– No engine re-design needed.

– Ran TFP on Field Gas!

• Only pumps capable of 100% Gas!

– Run either on diesel OR Natural gas.

– Maximum fuel flexibility.

• Gain efficiency going to Natural Gas!

On-Site Fracking - Natural Gas Fueling Options


Natural Gas Commissioning

Key Points:• TFP uses 7.4 mcf per hour on idle and 27 mcf per hour 2000 HP.• Gas system simpler than diesel with less mechanical auxiliary

systems - 10% more mechanical horsepower!• No visible smoke signature – even better emissions.


Job Parameters :

• Rate: 80 BPM

• Treating Pressure: 8,500 psi

• Pump time: 2 hrs.

• HP: 31,500 HHP (5 TFP dual Units on line, 2 idling)

Fuel consumption per stage:

• Diesel = 3,150 gals @ 4.00/gal = $12,600

• LNG = 5,355 gals @1.50/gal = $8,032

• Natural Gas = 540 mcf @3.50 mcf = $1,890

@5.00 mcf = $2,700

5 Stages/day = $50k/day or $1.0M per month!
