Conversion to 3D a drillhole trace on sampled table informations as Depth-Azimuth-Dip

 

Sampled data condition;

Where,summaried conclusions of conversion steps related on "get lengths of  the separate segments" based on informations expressed of upper four column;

Note.I especially inform  for a depth as 500 m that using some methods is a requirement against to matters as big posision errors.You are right!!!I imply to role about a "interpolate survey" position of this methods.Among this type methods:

• minimum curvature method
• radius of curvature method
• tangential method

are selective.There is  a nice explanation page based on advantage and disadvantages about methods of Wellpathpy;
