390 - APPENDIX A Structure Log www.alt.lu Description: The Structure log can be used to pick structure/fracture data interactively and record depth, dip angle, azimuth (dip direction), true aperture and structure classes. You can also import the data from ASCII files. Since WellCAD version 4.2 the user can define its own structure ranking scheme. To be compatible with older versions of the Structure Log the former Type and Description data columns will automatically be converted into Type and Description attribute classes. Note that most of the features offered by the Structure Log are part of the Image & Structure Processing add-on module for WellCAD. Data Format: E.g. Depth, Azimuth, Dip, Class, Description Note, that the data values for the Type, Condition, Form, Opening classes displayed in the example above are the codes referring to a particular structure class and symbol in the corresponding Category Dictionaries created in ToadCAD. These codes are strings and do not have to be numerical codes as in older version of WellCAD. Display Styles: The data stored in the Structure Log can be displayed in one of three different styles. Projection Style: The great circle produced by the intersection of dipping plane and borehole is “unrolled” and appears as sine curve. To represent the apparent aperture the curve is filled with hatching.
W S N E APPENDIX A - 391 N E S W N Unrolled great circle appears as sine curve. Tadpole Style: Data is displayed as tadpole style arrow plot. The body of the tadpole with respect to the horizontal log scale shows the amount of dip, while the tadpole vector line indicates the azimuth (dip direction). Different tadpole colors and shapes are used to differentiate structure classes. Slab Core Projection Style: The intersection line between the dipping plane and a virtual vertical plane of distinct orientation (e.g. North to South) is displayed. Structure Log in Projection, Tadpole and Slab Core Projection style.
