Decommissioning & Abandonment of wells
As safety regulations get tighter and tighter. I am trying to get data on approximate /average costs for abandonment and decommissioning old wells. for land, swamp and offshore enviroment
In my research, I came across conflicting reports, where some of the casing sections are retrieved and some others where they are left and cement plugs set in place.
The cheaper option would obviously be leaving the casing in-hole and setting appropriate number of cement plugs and bridge plugs, retrieving the well head and restoring the location. offshore decommissioning would involve a rig/vessel.
