Will VelocityManager velocity model and depth convert my time grids created in a standard industry mapping software?
Yes, VelocityManager is designed to seamlessly link to the grid and data files (binary) of leading mapping packages, without recourse to re-formatting etc.
Does VelocityManager model velocities from well data and seismic velocities (stacking and migration velocities)?
Yes, VelocityManager will model from both well data, via a sophisticated function browser, and it also supports a comprehensive use of stacking and migration velocities - optionally in conjunction with well data.
Can I QC my data and my velocity modelling?
A significant range of QC features are integral to VelocityManager, including a comprehensive data validation process at the onset of all projects. QC of processes is integral to the design of the software.
Can I model data from deviated wells ?
VelocityManager is designed with deviated and horizontal wells in mind, without any compromise to the accuracy. It does not require velocity logs for such wells, and will manage literally any number of deviated wells in a single project.
Will VelocityManager create depth grids which will honour the well data?
All velocity models created in VelocityManager are designed specifically to honour well control data, and will always result in depth grids which tie to the well data - for the right reasons.
Is much skill required by the user to achieve accurate results?
VelocityManager is unparalleled in being user friendly, highly intuitive, and designed for both the infrequent user as well as the expert. With its sophisticated project management, it is very easy and very fast. Highly accurate results are easily achieved.
Can I run multiple scenarios for a depth model?
Yes, quite simply the software is designed to allow a large range of scenarios to be run.
The VoK function often offers a more coherent model, but in my project many of the wells are deviated, can I still use the function VoK?
In VelocityManager the coefficients for all functions are solved by a highly advanced optimisation algorithm. The algorithm can solve for both Vo and K for both deviated and horizontal wells. This achieved to an exceptionally high degree of accuracy, without any requirement for well velocity logs.
Can I depth convert fault planes?
Yes, fault plane grids can be depth converted using the velocity model derived from the layered model, and the results are extremely accurate.
In my project, structural complexity in the overburden is causing depth ‘artefacts’ in my final depth maps, can this be avoided in a layer cake model?
Depth artefacts can be a severe problem for the analyst. VelocityManager incorporates IMR Plus which is specifically designed to compute and remove the artefacts without recourse to filtering the data. This has proven to be a highly effective process.
I often require depth migrated results, though my seismic has only been time migrated, what solution can VelocityManager offer?
Depth migration of time grids is achieved in VelocityManager with Image Ray Tracing. This is a very useful, accurate and robust implementation of the approach. It is very easily implemented to achieve impressive results.
When I model the velocities from my stacking velocities, I know that there are many anomalies and bulls-eyes in the mapped velocities, can I remove these undesirable artefacts in VelocityManager?
Such artefacts are common to seismic velocities, and are very easily removed, prior to depth conversion. |
