... gridding method, and it forms a comprehensive structural mapping workflow. Using this method can avoid structural distortion problems caused by sparse seismic observations and ensure those contour lines which are in or nearby fault zones are more reliable than conventional structure mapping techniques...

The result is a well projected and tightly constrained surface that closely honours the form of the interpretation from the interpreter. The technique allows seed grids...

While the reservoir grid can be defined using either straight or curved grid lines, most of the commercially available simulator preprocessors can only support straight...

..., a skilled interpreter will hand pick a dense grid of lines which are subsequently gridded to form a map. One of the more promising is the identification of discontinuities in the seismic spectrum where Liner et al. (2004) showed how such discontinuities can be used to map unconformities. An obvious way...

... the extent of a fault, the fault surface must be limited by other means. The geospatial approach uses a tip line polygon that represents the area of displacement. This polygon is not the same as a fault heave polygon that is used in traditional two- dimensional mapping. The tip line polygon represents the XY...

Variable density maps are considerably more cost-efficient and time-efficient to produce. Some of the filtered maps have...
