a) b) c) d) e)

Go to the link http://www.alt.lu/wellcad.htm Go to “Downloads” option in the WELLCAD drop down menu. Alternatively, you can select the “Downloads” option from the SUPPORT drop down menu. Download the following free packages: WELLCAD READER and WELLCAD EVALUATION (ensure you have enough memory space on your computer). Both packages will be installed in the following directory: C:\Program Files\Advanced Logic Technology. Also download a copy of the documentation to the same directory (“Wellcad Basic” V4.3 is recommended for beginners) .

2. Importing Data Wellcad allows you to import log data stored in various formats (e.g. *.WCL ,*TXT, *.CSV etc) and these can be used to create other logs as well as perform some complex analysis on the data. Before proceeding to steps required to import data, spend some time to read the following sections found in the Wellcad basic documentation: How to use this manual What’s New in WellCAD v4.3 Book 1 - WellCAD Basics 1.1 WellCAD Workspace 1.1.1 Tool Bar and Title Bar 1.2 Borehole Documents 1.2.1 Loading and Saving Borehole Documents 1.2.2 Creating a new Borehole Document 1.2.3 Draft, Presentation and Print Preview Modes 1.2.4 Document Handling 1.3 Logs 1.3.1 Log Types and Their Characteristics 1.3.2 Basic Log Editing 1.3.3 Log Settings 1.4 Basic Document Editing 1.4.1 Depth Axis 1.4.2 Data Import 1.4.3 Header and Trailer 1.4.4 Templates 1.4.5 Data Export 1.4.6 Printing

a) b)

Start Wellcad Examples of WELLCAD documents *.WCL can be found in C:\Program Files\Advanced Logic Technology\WellCAD Evaluation\Samples. Use the following steps to open and visualize their content: File  open. The display can give you clues on how to best plot multiple data logs in your workspace.

c)

In order to import a single file use the following option: File  import  single file; substitute multiple file in place of single file when you want to import multiple files or core images. NB: Wellcad software is case sensitive to the names of files used e.g. “DATA.csv” results in an error message whereas “DATA.CSV” will be read with no problem. The illustration below shows how you can import various well logs from “5L-38 CMR.CSV”

At this stage, you have the option of importing all the logs or only a few. For this exercise, import T12R, KTIM_TAPER and BFV_TAPER. The imported logs are shown below

In the plot above, the KTIM_TAPER log is plot on a log scale. You can do this by selecting the log of interest and then selecting the following options from menu options: View log settingsmain settings

3. Creating Cross plots Tools Cross plot

Crossplots can also be tailored to include information of a third property such as depth. The axes labels and titles can be modified by using the Plot, X, and Y settings found the View drop down menu. There also exist other ways of interactively analyzing your data (e.g. cluster analysis, creating percentage logs, adding regression lines…etc, see section 1.8).

4. Including annotations in your display See section 1.6 of Wellcad manual 5. Saving your project File Save

Note the file extension “*WCL”.
