Hi all,
can someone tell me why in sometime some gas wells produce water during production? it's due to what?
cementation problem, reservoir problem or other one?

and also what the terms below refer to in gas production/exploration process.

• wellbore
• skin effects
• re-entries
• BHP
• Gas sweep
• flow tubing pressure

thanks and regards.

SenOil,
I'm not an expert on gas wells but I will try to offer some answers.

can someone tell me why in sometime some gas wells produce water during production? it's due to what?

It's because there is water in the rock. This can be either water vapour saturating the gas, or free water coming up from below the gas layer. If there is too much free water being produced then the well is in the wrong place (the geologists have made a mistake).

• Wellbore: this is the actual hole, as distinct from the surrounding rock formation
• Skin effects: If you don't use the best cosmetics, you risk losing that soft complexion which is so important to a driller
• re-entries: don't know
• BHP: bottom-hole pressure
• Gas sweep: don't know
• flow tubing pressure: this is meaningless, just three unrelated words. Maybe you meant to say flowing tubinghead pressure, which means the pressure at the wellhead when the well is flowing.
