production production dudi06 (Petroleum) (OP) 10 Aug 13 03:57 .what is maximum attainable production from the well with given influx of 160 BPD with drawdown of 200 psi ? RE: production zdas04 (Mechanical) 10 Aug 13 10:37 You're new here so I will try to explain what is wrong with your post. People who might answer you question are volunteers. You have to ask yourself "why would they spend their valuable time answering my question for free?". The answer is that we like to have stimulating and interesting discussions. Your post is unlikely to lead in that direction. The problem with your post is that you don't give any information at all. How deep is the well? What is tubing/casing size? What are the fluids? Any gas? How do you know the "influx is 160 psi"? What is tubinghead pressure? Is there a downhole pump?
