Haynesville Shale
Haynesville Shale Key Properties
Depth (ft) 10,000 +
Thickness (ft) 200
Reservoir Pressure (psi) 3,000 – 4,000
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
