temperature these all
normally every well head contains one controller panel
itself this controller will monitor all above mentioned
this is called well head protection system
Actually there are different type of wells in oil field:
skid pumb(lufkin ie.. donkey pumb)
screw pumb
these pumbs are decided by vendors which is suitable for
purticular location

very high there can choose screw pumb, same way high
viscosity crude location there may skid pumb
