Procedure 1 Filtering Data in the Project
Browser
You can filter the data displayed in the Project browser to show
only what you want to view. After you apply a filter, only the
elements matching the filter criteria are displayed and the Project
browser changes color.
There are two methods in Techlog for managing filters. This
procedure shows you how to filter data by using the Filter tab or
the Create a filter menu command.
1. In the Project browser Properties window, open the
Filter tab and select the filter criteria for these options:
• Well: Apply a filter with a specific well name, or with the last
modification date or date of creation.
• Dataset: Apply a filter with a specific data set name,
sampling, last modification date, date of creation, or type.
You can make several selections at one time.
• Variable: Apply a filter with a specific variable name, main
family, family, unit, version status, last modification date,
type, or description. You can make several selections at one
time.
• Group: Apply a filter with a group name.
Common operators are AND (&) and OR (|), but you also can
use an asterisk (*).

Conditional selection is an option that allows you to select one or
several curves, wells, or data sets. For example, you can use this
option to select specific curves to drag into a LogView layout.
Conditional selection is available only in the Project browser.
Similar to the filter option, there are two ways to manage
conditional selection in Techlog, in the Properties window and
with the Conditional selection command.
1. In the Project browser Properties window, open the
Conditional selection tab and select the filter criteria for
the Well, Dataset, Variable, and Group options.
The variables, data set, and wells selected by the conditional
selection are highlighted in gray.
2. To remove a conditional selection, click in the Project
browser.
Procedure 3 Grouping Data Objects Manually
You can group wells, data sets, and variables manually according
to the properties available in the wells, data sets, and logs.
Manual grouping is accessed from the Project browser.
1. In the Project browser, select at least two wells, data sets,
or variables.
2. Right-click and select Group.
3. In the window that opens, enter a name for the group and

Lesson 3 Synchronization Tool
The Synchronization tool allows the asset teams to work in a
collaborative environment where data can be transferred to and
from a shared Techlog project.
Each team member must create a personal project on their local
space and from this personal project, they can link to the shared
one. After the projects are linked, team members can share their
data with the community through a send and retrieve mechanism.
Figure 15 How the Synchronization tool works
Project Partial Loading Feature
It is recommended that you disable the Project partial loading
functionality when using the Synchronization tool, because the
Synchronization tool displays only the wells loaded in the
Project browser. Using the Project partial loading feature might
lead to a mismatch between the Reference repository and the
current project.
- 48. Basics of the Techlog Window Schlumberger Internal Use Only

©2011-2013Schlumberger.Allrightsreserved.
Procedure 4 Sending Items from the Current
Project to the Reference
Repository
In this procedure, you send items from a local project to the
reference repository.
1. After you worked on your data, reopen the Synchronization
tool.
2. From the Current project pane, select the items that you
modified.
3. Click to send the items you modified to the Reference
repository pane.
Data Locking
You can lock data to prevent other users from overwriting the data
that you currently are working with. When data is locked, other
users still can retrieve them and modified them locally (in each
user project), but they cannot send their own changes to the
Reference repository.
You can lock data and view the locked items from either the
Current project or Reference repository pane. However, the
items are locked in the Reference repository pane only.
Therefore, items that exist only in the Current project cannot be
locked. In case of an error, a warning window opens listing all the
objects that were not locked in the Reference repository.
- 51. Schlumberger Internal Use Only Basics of the Techlog Window
Techlog Fundamentals, Version 2012 37
©2011-2013Schlumberger.Allrightsreserved.
Procedure 5 Locking Data
If you want to send a Techlog object to the Reference
repository, you must lock it first.
1. From both Synchronization tool panes, select the items to
lock.
2. Click Lock.
3. Click Close to validate. From the Project browser, you can
see a padlock on each locked item.
NOTE: From the Project browser, you can see only the
data that you locked. Go to the Synchronization tool
to see the data locked by other users.
If another user forgets to unlock the data, a data
administrator can unlock them.
If all the items in a specific group are locked, a padlock on
the group name is displayed.
If you have items inside a group with at least two different
lock statuses, the icon is displayed in the parent Lock
status column.
NOTE: When several users use the same Reference
repository to exchange modified data, some
conflicts might appear between your Current project
and the Reference repository. Several tools exist to
resolve potential conflicts. A discussion of these tools
is beyond the scope of this training. More information
is available in the Techlog User Guide.

Lesson 4 Techlog Project Creation
In this lesson, you will learn how to create a new project in
Techlog.
Procedure 1 Creating a New Techlog Project
The first time you open Techlog, most of the menus and dock
windows are disabled (they appear in gray). This is because no
project is open. You will need to create a new project first.
The Project template option allows companies to define clear
formats for any feature in Techlog that must be applied for a
dedicated addressee. This option typically is offered to service
companies that deliver standard output on a per customer basis.
The Project template option copies the whole project (including
data) defined as a template into the newly created project. All of
the settings applied in the project template then are available for
the new data that will be loaded into the new project.
1. In the Techlog main window, select Project > New to
open the New project wizard.
2. In the New project wizard, enter this information:
• Project name: Avoid using a slash () in the project name.
• (optional) Country: Entering a country will help you to filter
your projects later.
• (optional) Description: Enter information about the project.
3. Click Next to go to the Folder, status and type page.
The project is added to your Project folder automatically. If
you wish to store it in another directory, click the ellipses (...)
button to navigate to and select another location.
4. (optional) Choose a Project template from the list, or
browse for it by clicking the ellipses (...) button.
5. Set these options for the project template:
• Project status: In progress or temporary.

Module 2 Data Import and Export
Techlog can integrate many types of data, including log data,
point data, seismic, deviation files, and image files. Techlog also
supports a variety of the most common formats, including LAS,
GeologASCII, DLIS/LIS, ASCII file with the wizard, core images,
TechCSV, and the Techlog format (XML).
In addition, you can export data or any object created in Techlog
(such as plots and layouts) from Techlog to various format such
as LAS, DLIS, GeologASCII, ASCII file, TechCSV, and the
Techlog format (XML).
Learning Objectives
After completing this module, you will know how to:
• import data files, such as DLIS, LAS, and TXT formats
• import spreadsheet files
• import image files, such as PNG and TIFF
• import XML Techlog files
• export data from Techlog
• use the Well Identification Solver.
Lesson 1 Data Import
You can import data in four ways:
• Drag the files to be imported into Techlog (LAS, DLIS,
Techlog XML, CSV files).
• Select Project > Import from the main Techlog window.
• Select Home > Import .
• Press Ctrl + Shift + J,I.
Regardless of the method you choose, the action opens the

©2011-2013Schlumberger.Allrightsreserved.
5. Enter a name using the correct naming convention.
You can enter the name or choose a predefined pattern. The
name of images file must comply with the naming convention
for images. For example, if your image is named
Well1_CoreImages_1567.png, the naming convention is
%WellName%_%DatasetName%_%DepthTop%
If the name of the file is more complex (for example, if the
core image file is CD10789 with 10789 as the top depth of
the core), you must type CD%DepthTop% with CD before the
% to make sure Techlog recognizes the depth automatically.
6. Copy images into the project by selecting the Copy all images
into the project check box.
If you do not select this option, a link will be created between
the variable and the actual image during the import process.
TIP: If there are a lot of images to copy, the performance of

The table in the lower left corner shows you how the data is
stored (a data set with a link to the image at each depth). The
scale in the right lower corner lets you preview the images.
17. Review the depth table and note the empty intervals.
18. In the lower right corner of the window where a view of the
image is available, modify the zoom factor.
Each time you click Preview to apply a modification, the
scale is updated.
TIP: The Maximum interval option is ignored when the top
and bottom are available. If only tops are available,
Techlog runs a check on the difference between them,
then determines the maximum interval.
If the difference between tops is longer than the
maximum interval, the core length will be equal to the
maximum interval. This prevents the core image from
being stretched between the two tops.
19. Click Load to the import buffer.
The data is now added to the import buffer. You can see the
DaylLight and UV data sets under Well9. Notice the different
references: MD for the DayLight data set and CDEPTH for

Lesson 7 XML File Import
XML files are data files that have been previously processed and
exported in Techlog. This format contains all the additional
information that a variable can carry, including an associated
palette and well color.
There are two ways of importing xml files into Techlog. Method 1
uses the import commands on the menu; Method 2 uses a drag-
and-drop function.
Procedure 1 Importing XML Files from the
Import Buffer
In this procedure, you import an .xml file created in Techlog using
the import buffer.
1. Select Home > Import to open the import buffer.
2. Select File(s) import from the drop-down menu.
3. Click Open to choose the .xml file you wish to import. The
data you import are automatically loaded into the import
buffer.

Procedure 2 Importing XML Files with a Drag-
and-drop Method
In this procedure, you import xml files using a drag-and-drop
method.
1. Drag your .xml file into the display area.
The files are parsed automatically in the import buffer,
because .xml is the Techlog native format.
Techlog XML data file is the preferred format when
exchanging data between Techlog users, because it
preserves all Techlog-specific settings (Families, History,
Well Color).
2. Choose the data and click to import the data into the
Project browser.
3. Click Delete to clear the contents of the import buffer.

Lesson 8 Time Data
In this lesson, you will learn how Techlog handles time data. In
the previous exercises, all the references were Measured Depth.
Sometimes you might have to upload data with a different
reference such as time data.
Techlog manages data with 16 significant figures (double
precision data). This allows it to support date-time data. A variable
is considered date-time data when its family is Date Time.
You can create a data set with a reference in date-time by
following a simple workflow within the Project browser or the
Data editor. You also can import and save date-time data in a
Techlog project. All data processing tools (such as resampling,
combining or resizing data sets, and time shift) work with date-
time data.
In Techlog, a Date-time reference is stored as a number of milli-
seconds since January 1st 1900. For example, December 21st
1983, 21:26:11 is stored in the database as 2649878771116.07
ms.
You can load these date-time formats into Techlog:
• yyyy-MM-dd hh:mm:ss.zzz
• yyyy-MM-dd hh:mm:ss
• yyyy/MM/dd-hh:mm:ss
• yyyy/MM/ddThh:mm:ss
• dd/MM/yyyy-hh:mm:ss
• dd/MM/yyyy hh:mm:ss
• hh:mm:ss dd-MMM-yy
• hh:mm:ss/dd-MMM-yyyy
• hh:mm:ss.zzz
• hh:mm:ss
- 96. Data Import and Export Schlumberger Internal Use Only
82 Techlog Fundamentals, Version 2012
©2011-2013Schlumberger.Allrightsreserved.
To upload other formats, go to the Import buffer Properties
window where you can add a specific date-time format that is not
handled by Techlog by default.
You will need to combine these expressions to import specific
date-time files.
Table 1: Expressions to Create Date-time Formats
Expression Output

Exercise 2 Uploading Time Data with Time
Reference
In this exercise, you upload a second file containing time data as a
reference. If you drag this file into Techlog, the file will be
uploaded as any ASCII file. However, in the Project browser, you
can see that the time reference has no family. It will not load
correctly.
Furthermore, in the Project browser, the reference appears to
have no family and no unit. This indicates that the time format has
not been recognized by Techlog.
