Overview:

This report presents an overview of the kill resource requirements for controlling potential blowouts from the structures developed by the Operator.

Both relief well and top kill (snubbing operation) have been investigated. The scenarios studied included the drilling into top reservoir zones before setting 9-7/8 inch casing with zones partially penetrated and flow from all zones through 9-7/8 and 10 inch casing unrestricted to surface.

The results reveal that the blowouts from these high productive gas reservoirs will be very difficult to kill, and may require the drilling of two relief wells for a dual intersection and kill operation.

The kill requirements for the snubbing kill assume a new pipe can be snubbed into a well flowing underground were also investigated. Snubbing kill is not possible if the blowout occurs before the 9-7/8 casing is set under the conditions studied. Snubbing kill can be an option for some scenarios, and in particular in combination with relief well kill. This is also an option, which should be investigated further if a gunk material kill should be used.

All scenarios show very high gas outflow rates with a maximum at 620 MMscfd. Simulations were made using the Olga-Well-Kill simulator described in reference 1.
