#Techlog training manual update
To define or update the unit designation, refer to the Properties column > Main parameters tab.If no assignment rules exist for the particular variable, refer to the next section below. To assign a Family, RMB click on the variable and select Reassign Families (Fig.If any of the dataset variables are grayed-out, it implies that either the family assignment or unit is missing (VS1, VS2, PEFL and HBHK in Fig. 9)įigure 9: Contextual Right-mouse-button Menu for a well, dataset, and a variable.Ĥ. rename a well as Exp-Site-Hole instead of the default long name given from the source file) (Fig. Select any of the items in the Dataset and click the right mouse button, and the contextual menu will appear, with the different functions that can be applied (e.g. If the Property Panel is hidden, simply press F4.ģ. Click on any of the Dataset items and the corresponding properties will be displayed in the Property panel (see Fig. The data is arranged in a hierarchy, starting with the well (blue derrick frame icon), dataset (yellow curve icon), and variable (blue curve icon).Ģ. In the Project Browser, expand the Dataset by clicking on the triangle next to it on the left (Fig.6-3).įigure 7: Data import wizard for DAT, TXT and CSV files.Īfter importing a dataset, it is a good practice to browse the different variables to make sure that they have all the parameters required for plotting in Techlog (e.g. In the import buffer panel, select the well name and click on the left-pointing blue arrow (Fig.You also have the option to not import a column (Remove column)

#Techlog training manual windows
Using Windows File Explorer, select a DAT, TXT or CSV file and drag into the Import Buffer Panel (Fig.To close the Import Buffer, click on the X icon (Fig. When the progress bar for the import process disappears, click on the bin icon to purge any file in the import buffer (Fig. To import, click on the blue arrow pointing left (Fig. click on a particular dataset for that well.Ĥ. Click on the well name (e.g., Expedition 374, Site U1521A), or Once the data is parsed in the Import Buffer, you can either: Consult the Logging Technician or Engineer to identify the files that you may need.ģ. The same is true for a LAS file, which is a more streamlined dataset. The example given in Figure 6-2 is for a DLIS file, which is a generic file type that exists for both raw and processed downhole logging data. Techlog will try to automatically parse the data and select the appropriate import type. Simply click and drag a file to be imported into the Import Buffer panel. Using Windows File Explorer, navigate to the location of the file that you want to import. The Import Buffer panel will appear next to the Project Browser (Fig. Under Home menu (upper right), click on the Import button (Fig.(Module 2 in Techlog Fundamentals) Importing DLIS and LAS files 5).Ī new project is now created containing a few layout and cross-plot templates used in IODP.įigure 5: File browser showing the location and IODP-Techlog. In the next (fourth window), click Finish (Fig. Navigate to C:\Techlog-Projects\IODP-Techlog_template\ and select IODP-Techlog_template.tlp.Ħ. 4).įigure 4: Second of four windows for creating a new project, where a template project is selected.ĥ. In the second window that appears, select a template project by clicking on the browse button (Fig. Exp123) and click Next.įigure 3: First of four windows that appear in creating a new project.Ĥ. On the upper left corner, click on Project > New. Once the program opens, familiarize yourself with the basic layout of the Techlog interface, as labelled in Figure 2.įigure 2: Main components of the Techlog window.ģ.
#Techlog training manual free
At any point during the plotting process in Techlog, please feel free to consult the Logging Technician for any questions.ġ. Launch Techlog by double clicking on the shortcut icon, either in the desktop or the Windows toolbar (Fig. Before starting, please discuss with the Logging Technician and Schlumberger Logging Engineer about the data location and structure. For more advance functionalities, refer to the Techlog Fundamentals Training and Exercise Guide.Ī logging dataset is very robust, consisting of many files and hundreds of channels or variables referred to by acronyms, and further multiplied by the different runs and versions (raw and processed). This document outlines the steps in creating a basic log and cross-plot of downhole logging data using Techlog.
