The present disclosure provides an automated interpretation workflow for smooth surface wrapping of an imaged volume. The methods use a volume attribute to classify data into regions corresponding to feature/uncertain/non-feature parts and use smoothing through the uncertain parts to connect the clear boundaries of the feature. Any volume attribute can be used as long as feature/uncertain/non-feature categories can be identified in terms of continuous or discontinuous threshold values or ranges. The workflow can be combined with interpretation of well-defined boundary parts to resolve uncertainty and can be used with both explicit single-z and implicit multi-z (level set) boundary representations.

Smooth surface wrapping of features in an imaged volume

A method of processing data points distributed throughout a geological volume is described. In the method, each data point is associated with respective geological attributes. The method provides for: coding the geological attributes of each data point as a respective character string; compiling a query character string defining sought geological attributes of an arrangement of one or more data points; searching the coded geological attributes for arrangements of data points having geological attributes matching the query character string; and identifying matched data points.
