PFAS - version 8.0


We, at ITC are proud to present the new PFAS version 8.0 that was released in October 2004. 

This version has a brand new look and feel, that will improve your efficiency working with well data. 

The power of PFAS is stronger than ever: 

  • Mix both depth based data and time based data - add a survey, and you can view all your data in TVD, MD or both.

  • Make your own calculations and put them into the PFAS menu. You will have more control over calculations than you ever dreamt of !

Existing users can upgrade from

News in version 8.0

  • Redesigned user interface where all data are shown in the main window.

  • User defined width of each data track (without using templates).

  • Save templates with the project data. This makes it easier to exchange data with remote locations.

  • PFAS “remembers” last screen layout for each project.

  • Improved printing capabilities – make more presentable reports.

  • Improved use of survey data.


Further development

ITC plans to implement WITS-ML to enable real time data exchange as soon as called for by one of our customers. The systemization and choice of WITS-ML expertise has been done – so we are ready to act.

Next version will include a user defined plug-in functionality for external applications. This will further on enhance the PFAS capability as the “Top Layer Application” for well planning and efficient drilling.


The PFAS Workbench

PFAS is being used by oil companies and has been developed since 1992. The main contributors are the Norwegian Oil companies Sage Petroleum and Hydro.

PFAS is a multi-disciplinary system for planning new wells, following up during drilling and for post analysis. PFAS is used by geo-mechanics, pore pressure specialists, petro-physicists, well-site geologists, drilling engineers and anybody who need to have access to well data and/or analysis tools.

Therefore, PFAS is a multi-user system, made for multiple persons to have simultaneous access the same data. Users may have differentiated access to various groups of data or calculation modules.

Data management

PFAS handles all kind of depth related data (for example logs or incidents related to depths) and time based drilling data. Attach a survey, and the reports can be presented in TVD or MD or both.

PFAS Workbench

PFAS Workbench handles all data on a project basis. This means that all data for one project (one well or one analysis) are stored in a set of files. These files can easily be copied to a new location or sent by email.

PFAS Data Manager

The Data Manager is an add-on to the PFAS Workbench.  The Data manager handles a database with data from all available wells that is easy to access for all PFAS users. This improves the availability of the data, in addition to a more powerful QA/QC functionality where data can be quality approved or attached to various project phases.

The figure below shows the data used by PFAS in a well planning process in Norsk Hydro.

NOTE: This is not required data, but it shows the power of the application. (A lot of useful information can come from only a few data in PFAS). QA/QC is an integrated part of PFAS.


  • Overburden – integration from density logs
  • Pore pressure using Eaton method, Ratio method or Quick Look method. Draw trend lines on sonic logs, resistivity logs or d-exponents.
  • Fracture and collapse – minimum and maximum mud weight boundaries from geo-mechanical data.
  • Breakout Analysis to calculate stress directions.
  • Inversion Technique to calculate stress directions and magnitude
  • Log smoothing
  • User defined Calculations. A powerful way for the users to insert their “own” calculations into the PFAS system.


  • Present all kind of depth related data in TVD or MD.
    • Logs
    • Survey data
    • Geological information (lithology, litho-stratigraphy and chrono-stratigraphy)
    • Symbols for FMT, RFT, annotation, faults, tight hole problems, gas values, hydro carbon, composite data symbols, shallow gas, swelling clay, coring, different types of comments (related to depths) and much more.
    • Free text comments can be placed anywhere on a presentation.
    • Use templates and your company logo for uniform and representative reports.
  • Time based drilling data
    • Time based data can be mixed with depth based data.
  • The reports can be shown on the screen, printed on a printer or plotter, or you can write the report to a graphic file (jpg, tiff, bmp, wmf or emf) for use in documents.


Why is the Planning  & Field Application Software (PFAS) unique ?


1)      The Software has been developed over a long period, starting in 1992 based on the need to have multi-skilled well support groups to co-ordinate the drilling and well planning process in an modern organised oil company.

2)      PFAS is the “Top Layer Application” where all well data can be stored and presented. PFAS can read ASCII data on any format, and can also export/import data to and from special software from other vendors. Typically it will handle Geological, Seismic, Geo-mechanical, Geo-pressure, Drilling and Petro-physical (log) data.

3)      PFAS is the workbench and co-ordinating facility to enable the production and maintenance of a well plan throughout all faces of the operation.

4)      PFAS Workbench can be used as “a stand-alone” software. But the most efficient result is with the complete package, PFAS Workbench plus the Data Manager, with the database included, which handles both raw data and calculated data with a high level of QA / QC.

5)      PFAS is chosen in oil companies that want to adopt the philosophy developed through the development of PFAS, the “well support group”.

6)      ITC has a unique way of co-operating with the expert users in several companies, but in particular Hydro and leading Service Companies. In this way we have access to the most experienced scientists in the North Sea and the Middle East area.

7)      ITC is the leading well design and drilling operation training school in Norway, thus all needed training can be tailored and delivered at any location, with high focus on PFAS and well support group thinking.
