Dear friends,

I don't know much about reservoirs and I am facing a problem: I have an reservoir (gas) with water. Please help me with some answers to the following questions:

1. Temperature in the reservoir remains the same as initial time during the extraction of the gas?
2. The water content will increase or will remain the same ?
3. How can I calculate the pressure at the wellhead, when the pressure in the reservoir is 1/2 the initial pressure?

Thank you very much for your help!
