W ELL CONTROL New dynamic low choke method kills wells …

New dynamic low choke method kills wells at balance point using surface-applied pressure IN A WELL control situation when the casing pressure reaches the maxi-mum allowable casing pressure (MACP), the choke operator reacts by opening the choke to keep casing pressure at MACP, thus reducing the bottomhole pressure (BHP) and inducing a bigger kick.

Compressor Choke or Stonewall - EnggCyclopedia

Compressor choke is an abnormal operating condition for centrifugal compressor. Choking of centrifugal compressor occurs when the compressor is operating at low discharge pressure and very high flowrates. These high flowrates at compressor choke point are actually the maximum that the compressor can push through.
