Fixed bugs

  • Stick Chart: we have resolved the deselection of wellbores.
  • Check casings for some wells and wellbores on specific fields and for wells presenting Side Track.


Sometimes the RKB elevation doesn't appear, as it's too small compared to the max depth. Consequently, the scaled height in pixels representing the elevation goes to 0px. We are analyzing how to inform users about the datum elevation or to remove it.
