Introduction
• Deliverables:1) Reservoir Characterization2) Reservoir Development Options w/ Economics
• Findings:1) OGIP = 5.8 Bscf2) Economics - Gas Price ($4/Mscf)
• Gas Storage Infeasible• Infill Drilling Sub-Economic
3) Recommend Depleting Field to 500psi with Existing Wells.

Development Options
1) Production to Abandonment-Add Wells
-No Additional Wells
2) Gas Storage
![Page 7: Png 492 pec final-presentation[1][1]](https://reader033.vdocuments.mx/reader033/viewer/2022060123/55966fed1a28abee448b45a6/html5/thumbnails/7.jpg)
Abandonment Strategy
For P abandonment of 500psi:
1) Addition of One Well (Two Test Locations)
VS
2) Produce Existing Wells Until Depleted

Economics of Abandonment
• Plan Produce Original Three Wells to Abandonment Pressure (500 psi)
• Abandonment Date
• Total Gas Produced BCF
• At $4 Mscf
- Producing to Abandonment
- Stopping Production @ 1000 psi for injection

Gas Storage Strategy
Np, Pressures at inject
-Burst pressure (FG work)
Working Gas: OGIP-Np = 5.8-3.9 = 1.9 Bscf
No new wells, convert existing wells to injectors
-6month injection/production cycling

Gas Storage Results
• Losing X % per cycle
• -(Storage Cost + Summer Buy Price)*Vinj
• + (Winter Sell Price)*Vprod
• -12.5% *Value of Unproduced Accessible Gas
