Create Wireframe for a Fault structure

Michael Tangwari 8 years ago in General updated 8 years ago 3
I am trying to wireframe a fault structure intersected in 3 adjacent holes and exposed on the surface in creeks.....how do I do that??

You assistance is greatly appreciated.

Cheers

Mike - do you have the implicit modelling module? If so and you have some dip and dip direction readings it is a very easy procedure to use the fault modelling option with DH points as the input file (needs a minimum of 3 but you need Dip and Dir info) and the surface points as extra control points (2 will work). If you don't have Dip and Dip Dir for the DH intersections you need a minimum of 3 surface points with the DIp and Dip direction (evn if one is just a "guestimate location" properly noted as such of course) and you can then use the DH points as the extra control points (leaving the DIp and DIp Dir fields empty). Else you could combine them into a single file and use the DTM -> create surface with a projection plane defined by the points or normal to the dip of the fault - you will have to add a few extra points to extend the surface though. Perhaps someone else knows of a better way but for ease of use and best output the IM-Fault modelling option is a good step.
Maybe i not completely understood, but simply digitize fault on surface (by creek) and in section of holes and connect these two strings in dault DTM. Only problem can be if holes are too adjacent so you need to fantasy how fault goes
