Production, storage, transportation and handling of hydrocarbons and other chemicals generally require the use of chemically inert nitrogen.

Greene’s Applications: • Gas Lift: GOM & SOLA

• Putting a well back on line, taking the hydrostatic column out of the well after well shut in for a period of time

• Naturally flowing wells - no other artificial lift • Not a coil tubing job • No packer on the bottom of tubing • 10k psi pressure maximum • Cryogenics only

• Production Testing: GOM & SOLA • Means of stimulating a well that has choked itself off • Creating a pressure differential between the wellbore &

formation to reverse-frac the formation by dropping the pressure, stimulating production

• Naturally flowing wells - no other artificial lift • Horizontal and vertical wells • Not a coil tubing job • No packer on the bottom of tubing • 10k psi pressure maximum • Cryogenics only

• Pipeline Applications: GOM, LA, TX, MS, OK • Remove product from the line and replace with non-

combustable N2 that can be vented to atmosphere • Pressure testing of pipelines - dry gas pipeline • Purge/dewater pipelines in gas applications (post

construction, after pressure testing with water, routine dewatering)

• Can push foam pigs to dewater pipelines - volume rate maximum - 2000 scfm against atmospheric pressure

• Could push mechanical cleaning pigs/trains if offline and line pressure <500psi, <5 miles, <16" pipe

• Could push smart pigs if pressure <500psi, <5 miles, <10" pipe • Max pressure 10k psi • Cryogenics or bottles

• Purging piping or vessels: GOM, LA, TX, MS, OK • Purging to allow customer to safely open up the line or

vessel for maintenance, repair, decommissioning, etc. • Purging product to reduce piping temperature • Purging product to eliminate flammable material • Purging product to flush hazardous material • Cryogenics or bottles

to atmosphere with no disposal of waste costs • Preserves assets after testing before put in service • Bottle racks with booster - volume range 1scf-10,000scf • Cryogenics unit - volume range 1scf-1,500,000scf

• Decommissioning: GOM & SOLA • Nitrogen used to purge for decommissioning • Offshore pipeline • Offshore riser • Anything with a ballast system (some sort of reservoir that

needs to be purged) • Bottle racks with booster: Pressure range - volume range

1scf-10,000scf • Cryogenics unit: Pressure range - volume range 1scf-

1,500,000scf
