Try to Stay Ahead of the Production Curve

• Install Units Which Turn Up / Down Easily
• Valve Trays
• Variable Speed Pumps
• Use Multiple Trains if Possible
• Stay as Flexible as Possible with the Process

Conclusions

• All Shale Gas is Not the Same
• Watch out for Nitrogen in Shale Gas
• Anticipate Large Increases in Processing Capacity
