Every subsurface team has its own way of tackling depth conversion, which is why Velit ships with a broad, ready-to-use library of proven methods rather than a single fixed workflow. Whether you're building velocity models from curves, gridded surfaces, well logs, or stacking velocities, Velit's pre-configured methods let you get started quickly while still giving you the flexibility to bring in your own custom conversions when a project calls for it. The table below outlines the method categories available out of the box.
The depth conversion process can be run by the user, via the workflow system or the Wizard can be used to run a number of depth conversion to calculate the P10, P50, P90 values and produce the depth uncertainty for risk reduction in reservoir estimation.
Depth Conversion Workflow Tree
This workflow tree illustrates how the different depth conversion methods are organised within Velit, from curve-based and mapping approaches through to sonic log, stacking velocity, and user-defined conversions. Because every method sits within the same workflow structure, you can mix and match approaches, or run several in parallel, to build a robust set of depth conversion scenarios for your project. To see how this fits into the wider risk reduction and uncertainty analysis process, take a look at Multi-Z Depth Conversion or Risk Reduction - Depth Uncertainty.
