C. Performance Trend Observations
- Decline trends (comments on base performance, uncertainties and step changes)
- Prolonged shut-in behaviour (Evidence of recharge?)
- Interactions with nearby wells
- Other comments
     Note: Offset wells in B-18, B-16, B-10l, B-11U< B-9L high w/cut in J-25/30
     WI required if add perf in J-25 of B-9L
