About this document
Well Pressure Control Apparatus by luiscremaschi is a document available to read on EtoBox.
The document describes an apparatus for controlling pressure in an oil well. It includes a choke connected to the outlet of the annulus between the well bore and drill string. The choke regulates the pressure of drilling fluid circulating through the string and annulus to maintain the bottom hole pressure at a predetermined level. It does this by producing control signals in response to pressure deviations to automatically adjust the choke and keep formation fluid pressure within safe limits during drilling
