14 The Geological Surveying and Investigation in 3 Dimensions (GSI3D) software tool and 15 methodology has been developed over the last 15 years. Since 2001 this has been in 16 cooperation with the British Geological Survey (BGS). To-date over a hundred BGS 17 geologists have learned to use the software that is now routinely deployed in building 18 systematic and commercial 3D geological models...

“Whereas there are large seepages of petroleum along the Arctic Coast of Alaska and conditions favorable to the occurrence of valuable petroleum fi elds on the Arctic Coast . . .” President Warren G. Harding used those words in 1923 to describe the apparent petroleum potential of a tract of land on the western North Slope of Alaska, when he issued a one-page executive order establishing the 23-...

Three-dimensional (3D) geological models are important representations of the results of regional geological surveys. However, the process of constructing 3D geological models from two-dimensional (2D) geological elements remains difficult and is not necessarily robust. This paper proposes a method of migrating from 2D elements to 3D models. First, the geological interfaces were constructed usi...
