Well description
- Single continuous perforation in a sandstone body wherein bottom part of perforation is producing water (PLT validated)
Initial behavior
- WHFP =2700 Psi, Qg =10 MMscfd, Qw =30 BPD, Qc=10 BPD
After 1 year of gradual increase in water production
- WHFP =2100 Psi, Qg =3 MMscfd, Qw =382 BPD, Qc=2 BPD
- Within days WHFP dropped down to 700 Psi and well was unable to flow (constraint: customer line pressure is ~700 Psi)
- Well remained shut-in for five months and WHSIP increased to 2800 Psi
- I would like to know all possible reasons for this increase in WHP and possible strategy that can be adapted to bring the well back online in future

Well,
according to the related condition of the production well, gas inlet to well is of low pressure, so needs time to accumulate.
means gas outlet from well is greater than migrated gas through sediments.
Here, gas production well needs further development process.

Sounds like poor connectivity to the well more than water hold up. Reservoir is re-pressurizing. Try producing the well at lower rates, so the reservoir can keep up, or cycle the well on an off at some optimized interval to allow repressurization.
