Should also add...AT2 is closer to the water contact by some 300 feet or so, so over-producing is likely to accelerate water inflow to the well bore faster than the oil can migrate and adversely effect production.



The image shows roughly what we have...having both gas and water can help increase formation pressure and subsequent natural flow rates for longer periods.

As the oil is removed the water contact rises...but so too the gas also expands, meaning the presence of gas effectively delays the migration of water to the well bore. Gas can be problematic though if you are too high on the structure, unless you have separation capacity at the tree.

So...a question might be, did AT2 produce under its own pressure, or was the 1200bbls/d assisted?

If so...what decline rates did they experience and what did they do about it?

Did oil flows decline due to silting, waxing, water cut or water contact being breached?

What was the API of the AT2 oil?

Plenty of questions.

Cheers!
