The Green Field Footprint – 25,000 HPCLEAN TURBINE PUMPING TECHNOLOGY

In Summary• Our footprint is 1/3 rd the size of a conventional FracSpread.• Running on diesel fuel we meet Tier IV emissions.(ie: In comparison to reciprocating engines)• Running on gas, we are more efficient, run cleanerand have zero refueling logistics if running on fieldgas.• We can run on LNG, CNG, LPG or field gas.• Our dual fuel technology is proven and we have dualfuel units now.
