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 (*).

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. Techlog Fundamentals, Version 2012 33

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.



2011-2013 S

chlumberger. A

ll rights reserved. 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.

Project opening default mode: In Techlog 2012, only single-user is available (options are read/write or read only).
