Free Online 3D Well Path and Borehole Viewer: Rotate Your Subsurface

Report
Drag the scene to rotate it, or use the azimuth and tilt boxes. Boreholes are drawn as colored layer sticks, the deviated well from its minimum curvature survey in red, and the reference grid sits at the highest collar. Depth scale exaggerates the vertical when shallow detail matters.

Turn the picture with your hand

Plans hide depth and sections hide width; some subsurface questions only answer themselves when you rotate the picture. The app above renders your boreholes and a deviated well in true 3D on canvas, no plugins and no libraries. Boreholes appear as colored layer sticks at their real coordinates and elevations; the well path is computed from its directional survey with the industry-standard minimum curvature method and drawn in red from surface to TD. Drag to rotate, tilt, exaggerate the depth scale, switch on auto-rotate, and export the view as a PNG or printed report.

Three dimensional scene with layered borehole sticks and a red deviated well path above a reference grid, with a drag to rotate gesture indicated
Boreholes and a deviated well in one rotatable scene, so the geometry finally makes sense.

This completes the Maps and Sections Suite: plan view in the contour app, section view in the cross section maker, and the full three dimensions here, all fed by the same kind of data.

What the scene shows

  • Each borehole stick is segmented by its layers with the same USCS colors used across the site, so a clay layer looks the same in the log, the section, and the 3D view.
  • The well path comes from minimum curvature, the same calculation as this site's trajectory planner, so the red line is survey-grade geometry rather than a sketch.
  • The reference grid sits at the highest collar elevation and the north arrow rotates with the scene, keeping you oriented at any angle.
  • Depth scale exaggeration stretches the vertical when shallow layering matters; at 1 the scene is true scale.

Questions it answers at a glance

  • Does the planned well pass the existing boreholes, and on which side?
  • How deep is the well relative to the clay the boreholes found?
  • Do the layer elevations make sense together in space, or is one hole logged wrong?
  • What does the site actually look like, for the client meeting where a table of numbers dies?

What this app is for

Sanity-checking geometry before drilling, presenting site models without specialist software, and teaching 3D thinking with data students can edit live. Full geomodeling packages add surfaces, faults, and volumes; the core act of seeing your holes and wells in space, rotatable and free, is right here.
