Basic IP2 Win Tutorial

BASIC IP2 WIN TUTORIAL Basic Principles in Using IP2 Win Software Foreword Nowadays we are entering and living in a digital era where most of our activities are being helped by digital equipment. New invention in math, physics, and chemistry lead the world of engineering develops rapidly. A long time ago hydrogeologist and petrophysic scientist calculated and analyzed geoelectrical sounding data manually but now, the developing technology born new method to analyze geoelectrical sounding data. Geoelectrical sounding data can be calculated and analyzed digitally by using IP2 Win Software. IP2 Win software can analyze induced polarization data with some electrode configuration like Wenner-Schlumberger, Wenner Alpha, Wenner Beta, etc. Using computer to help calculate and analyze data will save a lot of time. There is a fact that most of us will agree, computer has a very small possibility to make a mistake in calculation. Unfortunately using IP2 Win is not easy. We need to be familiar with IP2 Win software tools so we can use that software effectively. By writing this tutorial book, I hope I could help people those are interested to use IP 2 Win software in order to help their work. This tutorial book just explain a basic step in using IP 2 Win from inputting data until creating cross section from two or more sounding points. Thank you very much for all people that help me to finish. this book especially Mr. Tjahyo Nugroho Adji (Hydrogeologist) and Ms. Kurnia Widhayanti (Mathematics Scientist). I said thanks too for all Hydrogeology World's visitors for your visiting and contribution. Data error is displayed on table title bar (error level in the example above is about 23.5%). Data error can be corrected automatically by clicking Point>Inversion. Manual data correction can be done by dragging the curve. The result from data correction appeared in the graph and error value on table title bar like picture above (there was a value decreasing from 23.5% to 6.82%). Close IP2 Win software by clicking File>Exit. Run IP2 Win software again to input another VES point data. Note: Every change made in IP2 Win will be automatically saved. That automatically save setting is default but, if the automatically save setting is off click File>Save for saving file. Inputting another VES point data also the next data analyzing with IP2 Win can be done after restarting IP2 Win software (there is a bug in IP2 Win software that appeared if IP2 Win Software is not restarted. 1. Introduction to IP2 Win Software IP 2 Win is software for analyzing geoelectrical data from one or more VES (Vertical Electrical Sounding) points. IP2 Win can analyze data from some kinds of induced polarization's electrode configuration such as Schlumberger, Wenner-a, Wenner-B, etc. Using IP2 Win includes some steps. The first step in using IP Win is data input, the second step is data error correction, the next step is adding data point, and the last step is cross section creation. Data input can be done directly from field data (sounding data consist of AB/2, V, I, and K) or indirect field data (sounding data consist of AB/2 and Rho_a). Output of sounding data that analyzed by using IP2 Win software are resistivity layer, log resistivity graph, resistivity-depth table, and pseudo cross section. The output can be exported in some data formats. Basic weakness of IP2 Win software is a bug that frequently occurs when analyzing data. That problem can be solved by restarting software
