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:

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

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).
