BoreholeLog Table• Used to store 3D borehole data
related with well features
• Each row in the table represents a point/interval along a borehole
• Data are related with a Well feature through the WellID attribute
• 3D geometry is defined by the TopElev and BottomElev attributes
BoreholeLog TableCombining the well geometry (x, y) and the vertical data stored in the BoreholeLog table we can describe a set of 3D geometries (x, y, z)

BoreholeLog TableExample of well completion data (screens, porous cement)
We can create 3D displays of wells with the elevation and depth attributes of the well feature

3D Visualization
3D Features - BorePointBorePoint is a 3D point feature class for representing point locations along a borehole (e.g. geologic contacts, samplers)
3D Features - BoreLineBoreLine is a 3D line feature class for representing intervals along a borehole
Non-vertical boreholes• The case of non-vertical boreholes is a bit more
complex
• Usually the data are given in a local coordinate system as a Azimuth, Dip, and Length
• The data is transformed to X, Y, Z coordinates and can then be visualized in ArcScene
