Dynamic Kill Modeling
Dynamic Kill Modeling and Analysis
Dynamic kill is a process used to kill a blowout well by pumping fluid into the wellbore at high rates to generate enough friction to suppress the flow. Simulations are run with transient two-phase flow models to design these kills. Scenarios that are analyzed can involve pumping through the drill-string or through a relief well. Results provided include pump rates, pressure and quantities of fluids required.
The advanced simulation model used for these designs is the "OLGA Advanced Blowout Control 2.0" simulator. This is the latest generation tool developed by Scandpower's SPT Group in cooperation with Wild Well. The software is able to analyze blowouts, as well as operating parameters, for the necessary kill process. This is particularly useful for today's deep, high-temperature, high-pressure and prolific wells.
Simulator Features the Latest Technology
The program uses the latest technology in transient multiphase simulation, and provides the following unique features:
- Live graphics display that provides comprehensive visualization of a blowout and its kill process.
- Multiple scenarios and kill options can be evaluated quickly, providing an ideal tool for real-time support of well control events.
- Results include blowout rate, kill rate, wellbore pressure profiles, volumes, fluid density and other dynamic kill parameters needed to restore control.
- Operational parameters can be changed in response to developing well conditions, just as in an actual kill operation; wellbore responses to such changes are immediately visible in the graphic output.
- Kill method options include:
- through the drill-string, on or off bottom
- through the relief well
- onshore or offshore
