"The subsurface industries started using specialised logging tools to identify geological structures in the 1970's, but it took much longer to introduce a scientifically based interpretation methodology. With our current software, we can routinely make full 3D analysis of image picked planes to estimate paleostress, fault trends, fracture aperture and paleotransport. For rock stress and mechanical properties we have a similar story: The theory of stress around a borehole was published over 100 years ago, but it wasn't until recently that we could build software tools to instantly pick far field stress from fractures on borehole images. The colleagues in Eriksfiord have pioneered geoscientific software and methodology for processing and interpretation of image and sonic logs. We are excited to see that what was considered a curiosity when we started is an indispensable part of the technology needed for new challenges such as subsalt drilling and injecting reservoirs into source rocks."
