Depth Conversion with bitmap seismic images

Here's an example of the sort of problem our DepthCon software is designed for. We've already looked at the Turner Valley field in Alberta, using TraceInterpreter, and we developed a model for the fault pattern, which was this:

 

 

Let's put this local information back into the complete time section:

The time section shows a pop-up, on the back limb of the fault-propagation fold. There's a velocity pull-up in the core of the structure, caused by repetition of the fast carbonates.

With DepthCon2000 we colour-overlay the interpretation, double-click on each colour and enter the appropriate interval velocities, and then combine the two images to give this:

When we combine the colour model with the time section the pull-up is greatly reduced in amplitude, though there is some structure remaining in the footwall, which is an interesting result. One can experiment, alter the picks and explore the sensitivities of the model to the values used. 

DepthCon2000 also has a simple-shear vertical and inclined shear option, user can sketch a fault surface and  move the hanging wall seismic image, by any required heave or for rejoins of severed markers, and this is interactive, the fault shape is easily altered. It can also construct fault profiles, and has a line-length balance capability.

DepthCon was withdrawn from sale in 2006 by agents RockWare because it attracted few inquiries. We may re-create it as a macro.
