Techlog 2011.1 Release Notes Introduction

Techlog delivers an industry leading wellbore software platform that provides petrophysicists,

geoscientists and engineers with a fully integrated, interactive, easy to use analysis tool for

interpretation of all wellbore data types (e.g. core, logs, images, photos…). Using Techlog, these

different disciplines can collaborate effectively by accessing and incorporating the same data into

the workflows; thus fully capitalizing on previous data investments.

Techlog 2011.1 represents significant development efforts, with a particular focus being devoted to

the user experience. A complete refresh of the user interface with the Techlog T-bar and the

introduction of new icons ensure that Techlog is even more intuitive and easy to use. The powerful

customization capabilities are available at different levels of granularity—from the corporate

perspective, within a project and down to the end user.

All of the new functionalities and enhancements are described in more details in these release

notes. Of special interest is the new Pore Pressure Prediction module, which incorporates industry

standard methods to compute the safe mud weight window and establish the fracture gradient to

ensure safe drilling operations. In addition, the implementation of GeoFrame ELAN functionality

into Techlog has augmented the previously named Quanti.min and replaced it with the new module

Quanti.Elan.

We hope you enjoy Techlog 2011.1 as much as we do.

installed depending on your computer hardware:

8/23 Schlumberger Private

Install Techlog xxxx.exe. This version runs in both 32 and 64 bits PCs.

Install Techlog xxxx (64-bit).exe. This version contains the 64 bits Techlog code and runs only on 64 bits machines (64 bits applications can only be run with 64 bits hardware and OS).

Install Techlog xxxx (32+64-bit).exe. This version contains both codes for 32 and 64 bits versions of Techlog. By installing it, one can each time chose the way he/she wants to run Techlog as a 32 or 64 bits application.

The Workflow overview

The vertical view:

o Allows the user to navigate easily between workflows and methods with a tree view

system.

o Possibility to load/create (right mouse click on the first branch of the tree) a new

workflow into this window, it will appear as a new group (new branch in the tree).

Each workflow can get its own inputs, zonation and parameters.

o Possibility to quickly define the methods properties and the workflow properties

(display, save, save and display, enable, remove, automatic launch, pause, close).

o Method to be edited can be directly selected from the left pane.

o There are now properties for each workflow; user can get to them by clicking on the

workflow name in the tree view.

Inputs table view:

o Summary of all inputs for the workflow selected in the manager view (table view

with possibility to filter on each column), possibility to fill up/down, transpose, etc.

o Each time the user changes an input in a method it refreshes the global view and

each time the user changes the current value of an input in the global view, the

method gets updated.

Parameters view: ability to define a parameter as “Global” for each workflow (workflow

parameter). The constant used in the overview will be applied in all method of the selected

workflow regardless the input dataset, zones, etc.

Outputs: Summary table of all outputs for the selected workflow with possibility to

enable/disable outputs rename, etc. (most of the properties already available in outputs

properties for each methods).

Method settings:

o New design and re-arrangement of the icon emplacement.
