By the end of this course, delegates will be able to:
Well Abandonment and Decommissioning Procedure and Relevant Costs Management Scope of Well Abandonment is to effectively seal-off all distinct permeable zones (i.e.,)the zones of potential hydrocarbons or water inflow (permeable zones penetrated by the well or perforated casing zones), to ensure that formation fluids are isolated, both within the wellbore and in annular spaces, that their migration among different formations and/or up to surface/seabed is duly prevented to protect the external environment.
