470 - APPENDIX A www.alt.lu As the Tilt, the angle between the vertical breakout axis and trajectory of the borehole, is recorded with each pick the display of a Rose Diagram Tilt can be displayed. The diagram shows the distribution of title angles between -90° and 90°. As for the Azimuth angle distribution you can count the picks as Breakouts, Tensile Fractures or Other events. All other settings for the diagram are similar to the Rose Diagram Dip for Structure Logs. Histogram Azimuth / Tilt / Opening and Attribute: Four different types of bar histograms can be created showing the distribution for each of the recorded parameters in the Breakout Log. The presentation settings are similar to the bar histograms for Structure Logs, except for the way of counting the picks and the scale mode. As explained for Rose Diagram for Breakout Log the way of counting picks is different for Breakouts, Tensile Fractures and Other events. For Opening, Tilt and Azimuth angle histograms two different scale modes are available. The vertical axis shows the frequency of occurrence if the Scale Mode is
APPENDIX A - 471 set to Counts. If the scale mode is set to Cumulative Length the vertical axis of the histograms is the length in meter. When displaying the distribution of attributes you can select the attribute class (i.e. the tadpole library) for which the distribution will be displayed from the Attribute drop down list. Mean Tilt & SHmax: Maximum horizontal stress direction and average tilt angle are calculated from all selected breakout picks found in each depth interval covered by the Polar & Rose diagram box. Tow different scaling methods are provided. Direction cosine and sine are averaged either by the number of measurement (Counts) or by the total breakout length (Cumulative Length). The values and vectors displayed depend on the way of counting the recorded components (count as Breakouts, Tensile Fracture or Other events) and the Scale Mode. Vector Azimuth and Tilt: Similar to the vector diagrams available for structural picks this type of diagram provides a graphical presentation of cumulatively added unit vectors of azimuth or tilt data. Adding the vectors from top to bottom (or vice versa) even small changes of breakout orientation over the investigated depth interval can be visualized and detected.
