Design and Supervision of Kill Operations

• Define the Kill Team organization
• Define the blowout scenario for which the kill strategy is being developed
• Define kill principle to evaluate: dynamic, heavy fluid, reservoir flood, reactive fluids, etc.
• Define kill fluids to evaluate
• Define kill depth
• Define injection flow path (relief well annulus, drillpipe, tubing, etc.)
• Define constraints on: HHP, injection pressure and flowrate
• Compute steady state kill parameters (minimum flowrate, mud volume required, time to achieve kill)
• Assess sensitivities on kill by: reservoir IPR, pressure and temperature, fluid properties, flowpath, water, losses, fracture
• Compute transient (versus time) kill parameters on chosen: kill fluid, HHP, critical injection pressure (surface, casing, downhole), kill fluid volumes, BHP, influx and outflow rate for blowout and kill fluid
• Define pumping loads for tubular design (relief well or surface kill)
• Choose kill method
• Define high pressure pumping plant
• Define kill fluid storage and transfer requirements
• Define kill platform (for offshore) or space requirements for land
• Supervise installation and QC of kill plant
• Supervise kill operation
