A state of the art simulator

OLGA®-WELL-KILL is a dynamic model for simulating multiphase flow in wells. The model is specially adapted to calculation of pump rates and mud volumes for a variety of blowout control situations. 

OLGA®-WELL-KILL is developed from state-of-the-art multi-phase flow simulator OLGA (by SPT). It can handle numerous well flow configurations - from a single vertical well to multiple horizontal wells with complex completions. With a fully portable system, assistance with the model is available on-site in a blowout kill planning and control situation.

Unique OLGA®-WELL-KILL applications

OLGA®-WELL-KILL was designed for planning and evaluation of kill scenarios and intervention options. The model can be used to:

• analyze blowout flow
• kill point
• pumping schedule
• casing design
• kill fluid properties and volumes
• temperature, pressure and other related parameters

The results may be presented versus time for a complete dynamic and volumetric response. Well kill applications for the model include:

• Dynamic kill simulations for relief well control operations
• Top kill simulations for underground or diverted blowouts from a rig or snubbing unit
• Bull heading analysis
• Momentum kill analysis
• Shallow gas analysis
• Production applications include:
• Production and injection flow characterization
• Horizontal well flow analysis
• Water alternating gas injection analysis

Features that are unique for well kill applications include:

• State-of-the-art multiphase flow technology
• Advanced controller system which is representative of real pumping operations
• High pressure pump models
• Oil and gas properties fully modeled
• Pressure and temperature effects on mud properties
• Non-Newtonian flow
• Well path obstructions and leaks
• Critical flow conditions
• Various models can be used for the reservoir inflow
• User defined graphical presentation

The results from OLGA®-WELL-KILL will typically provide:

• Fully dynamic simulations of the kill operation with pressures, blowout rates, pump rates, cumulative volumes, hydraulic horse power requirements and temperatures. Parameters can be displayed versus time at any point in the well(s).
• Calculation of necessary kill fluid rates, time and volumes to obtain dynamic and static kill.
• Sensitivity analysis of different kill fluids; water, brine or mud with different densities and viscosities.
