The first step toward 3-D interpretation of a 3-D volume is to use time slices. The value of time-slice interpretation for faults is fairly obvious. Regardless of the strike of the fault, most fault surfaces intersect the time slice at an angle between 45° and 90° to the plane of the time slice | The first step toward 3-D interpretation of a 3-D volume is to use time slices.
