Abstract
Moreover, later phase of development brings in hard-to-recover reserves, such as highly viscous and super viscous oil (SVO), extracted with thermal recovery methods (steam injection, downhole combustion), using SVO wells for shallow reservoirs with inclined wellheads and long horizontal sidetrack fitted with filters. Thus, creating additional risks of gas, oil and water inflow.
Key words:
gas, oil and water inflow, bottom-hole condition prompt assessment method, well kill operation methods for wells with several penetrated formations, strength certificate determination
