United Downs 1 borehole image interpretation
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.

- Statement
-
Features were interpreted on acoustic borehole images processed by BGS using the Schlumberger Techlog software. Acoustic borehole imaging is sensitive to changes in the borehole wall. The acoustic imaging tool emits P-Waves and records the amplitude and travel time of the reflected waves . Both the amplitude and travel time data can then be processed into false colour images to characterise the lithology, faults and fractures present at the borehole wall. This sensitivity to changes in the borehole wall means that where there is a significant increase in the borehole diameter (known as a washout) fewer, or no features can be interpreted from the imaging.
