Improving production through well control

[pet_spec]

Is there anyways to reduce BHP pressure (except using chokes or valve) that allows to increase drawdown and production rate?

Is it possible to use in this case artificial lift and semi-submersible pumps to reduce BHP?

Thanks guys!

Yes, you can reduce the Bottom hole pressure (BHP). A simple explanation comes from the following equation relating Surface Tubing Pressure (THP), Hydrostatic pressure (Phyd) and Pressure losses due to friction (Pfric):

THP+Phyd = BHP+Pfric
Therefore: BHP = THP+Phyd-Pfric

By taking a look of this simple eq. you can infer that by reducing the THP (e.g. opening a surface choke) and/or reducing Phyd (e.g. gas lift operations and artificial lift methods) you'll be able to reduce the BHP. Artificial lift methods allows the reduction of the fluid column within the wellbore (i.e. fluid level), therefore reducing Phyd.
