General Information
Introduction
SafeVision Standalone allows users to “drill the well on the simulator”, displaying with
clear and simple graphics various critical relationships occurring below the rig floor.
The heart of the program is an advanced, fully transient hydraulics module optimized
to quickly simulate complex wellbore relationships.
The common display contains prioritized information rather than excessive raw data.
The emphasis is on providing a thorough overview of current well status using a
depth-based graph linked to a detailed well sketch. Display of time-based data is
optional and may be customized by the user.
Standalone Features
Well Visualization
•
Well sketch provides continuous display of well geometry
• Well sketch shows scaled diameters and depths
•
Sketch updates to display results of transient simulations• Depth-based graph is linked to the well sketch and displays critical downhole
pressures and pressure limits. This can be displayed in either equivalent density
or pressure units
• User-defined time-based logs can be used to record progress of simulations and
identify relevant operational events
Applications
• Helps demonstrate effect of surface actions on entire downhole well profile,
fully integrating multiple, simultaneous effects.
• Calculates and continuously displays pressures at all well depths, thus
clarifying critical relationships.
• When used to simulate drilling, consequences of complex changes in pore
pressure, formation strength, hydraulics, geometry and string movements can
be assessed
• Simulates well conditions with the BOP open or closed
Other Features
• Kick Tolerance Analysis
• Automated sequence controls enable simulation of drilling, tripping, and fluid
displacement processes without specialized skills• Fully transient simulations make it easy to “drill the well on the simulator”
• Simulation data is automatically recorded for easy play back and can be
optionally saved for later reference
• Optimized mathematical models allows for fast simulation of complex well
scenarios

Using the various refinement options you are able to select additional parameters that
influence kick tolerance to be taken into account by the software:
• Temperature affects
• Gas Compressibility
• Influx density correction
• No expansion
• Choke operator error
• Choke line friction
• Annular friction
The No Expansion option should be used in cases of water kicks or when the last
casing shoe is deeper than the bubble point depth, meaning the gas that entered the
wellbore will behave like liquid throughout the entire open hole section.
Results
The results tab displays the calculated kick tolerance graphically with the X-axis
showing volume and Y-Axis the Kick intensity.
