A highly-requested Strater feature that has been added in Strater 4 is the ability to display deviation paths in the map view. Previous versions of Strater allowed you to plot deviated borehole data in the borehole or cross section views, but did not show them as deviated, and did not show the deviation path in the map view. In Strater 4 you can display deviated boreholes in both the map view and the cross section view such that the deviation is visible. What an improvement!
To display deviated boreholes in the map view, you need to have a collars table containing wells, and you need deviation data for those wells (either in the collars table or in a depth/interval table or survey table). With the required data:
If you have inclination or dip and azimuth in either a survey table or a data table, Strater will calculate the true vertical depth for you (Data | TVD) using any one of a variety of calculation methods (tangential, average tangential, balanced tangential, radius of curvature, minimum curvature). If you have x,y,z and you want to calculate inclination or dip and azimuth, use the following conversion from cartesian to spherical coordinates:
if i do 300 m of bore hole from surface to Under ground, there will be a deviation of some degree. So i want to know how to calculate it manual without any equipments.
