Özet

© IMCET 2022. All rights reserved.In this study, two graphical user interface (GUI) based drillhole database applications, compiled by the authors, are introduced. The first executable applet is developed to automatically interpolate and calculate between survey stations in directional drillholes. In order to determine borehole position, Minimum Curvature Method (MCM) is assumed as the mathematical model. By employing measured depth, dip, and azimuth as input parameters, output parameters are obtained such as Dogleg Severity (DLS) and the 3D coordinates; northing, easting, and true vertical depth. Also, graphical output of the drillhole path is produced. Second applet is the downhole compositing tool. This application starts with 3D drillhole database import and validation. Raw and sample length statistics are given in detail by the program and users are able to create composites with desired length and minimum sample coverage percentage. Composite coordinates and values can be exported in ASCII or MS Excel.csv formats. Detailed composite statistics can further be reported.
