Derived From:: EpEntity_Entity

Capabilties:: read

The WellVelocity table defines sets of time/depth values used to convert time-to-depth or depth-to-time. For data increasing downward, if a given depth (time) value does not match an exact data point in the time-depth table, linear interpolation will be used to acquire the proper time (depth) value. If a given depth (time) value is deeper than the deepest depth (time) in the time-depth table, a constant interval velocity computed from the last two points in the time-depth table will be used to extrapolate the time (depth) value. If a given depth (time) value is shallower than the shallowest depth (time) in the time-depth table, a constant interval velocity computed from the first two points in the time-depth table will be used to extrapolate the time (depth) value.
