Media is any form of research output that is recorded and played. This is most commonly video, but can be audio or 3D representations.
wellpath in blue, other wells in red. 8–23 s: rotate view and turn on probe with seismic (blacks are peaks marking an increase in acoustic impedance). Zoom in and view probe and surface looking northwards. 24–33 s: trim back top Zone 45 Sandstone surface to probe to reveal underlying near top Zone 20 Sandstone surface. Note horizontal section of B25z. 34–57 s: move seismic probe forward and back over well. Top Zone 45 Sandstone horizon visible in grey on seismic probe. Note graben feature. 58–67 s: turn on red and blue graben bounding faults. Rotate to see original B25z well path intersecting the graben. 68–85 s: move seismic probe forward and back over well area. 86–94 s: rotate view anticlockwise so looking towards North. 95–113 s: turn on alternate sidetracks, rotate and zoom in. 114–132 s: turn off all well paths except final B25z drilled well. This drops short of graben. Zoom and rotate anticlockwise so looking Northwest along horizontal well path.
