Initial Production Rate (MSCFD) 2,500 – 10,000

350 °F Bottom Hole Temperature

Extremely Large Potential

May Pull Resources from other Shale Plays

Try to Stay Ahead of the Production Curve

Install Units Which Turn Up / Down EasilyValve TraysVariable 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
