United Downs 1 borehole image interpretation
Description
This dataset contains the borehole image interpretation of the United Downs 1 borehole, Cornwall (BGSID: 21246966) The acoustic borehole images have been interpreted for faults, breakouts and conductive and resistive fractures. For faults and fractures each line in the file defines a plane passing through the borehole. This includes: • Depth at which the plane intersects the borehole wall, this is defined as the midpoint of the feature as each plane has a top and bottom intersection. • Azimuth, this is the azimuth of the dip direction of the plane, it is at 90 degrees to the strike of the feature. • Dip, this is the dip angle of the plane. • Type, this is a classification of the feature. For breakouts each line represents an individual feature which covers and area of the borehole wall. This includes: • Depth the midpoint depth of the breakout. • Azimuth, this is the orientation of the breakout. • Type, this is a classification of the feature. • Breakout Height, the length of the breakout in meters. • Breakout Width, the width of the breakout in degrees. • Type, this is a classification of the feature. The work was undertaken by BGS as part of the GWatt Project award reference number NE/S004262/1. It was funded by the UKRI Natural Environment Research Council.
