Geological and technological factors responsible for blowout hazards in well construction, operation and workover

S.I. Vasiliev, E. E. Miloserdov, N.D. Bulchaev

By physical conditions causing gas, oil, water inflow and blowouts the presence of geological and technological factors in a well (generally, in the zone of open hole) is meant, which can potentially provoke unplanned and uncontrolled invasion of reservoir fluids in the process of well construction, operation or workover.
