The Data Processing Software for the Sondex Multi-Finger Imaging Tool (MITpro software) performs the task of processing MIT raw data automatically, but under interactive user control. It reduces the tedium of manually   analysing   the   data, producing consistent, reliable reports showing where and to what degree the pipe wall is damaged or scaled.

The software locates

collars in tubing or casing, using a range of specialised, automatic search algorithms. The results can be modified interactively, until a suitable description of every joint is obtained.

To process the data, the software uses algorithms, which correct for tool decentring and fit the interior shape of the pipe locally. All deviations from the fitted shape are merged and classified into damage reports. The software configuration can be adapted to process the data from any type of survey, using any Sondex MIT tool.

MITpro can generate highly reliable and consistent survey reports, which are stored as

ASCII format disc files. These include Summary Report Files, which summarise the findings as a Joint Tabulation, and Process Report Files, which contain detailed damage information.

The Summary Report can be printed out, to a high presentation standard, suitable for offering to end-users directly. Worst-case cross section plots can be generated and appended to the report automatically. Both metric and imperial formats are supported throughout.

The MITpro software is a 32-bit application, which runs under Microsoft Windows 95 or Windows 98. The software can also run under Windows NT.






        Cross-sections produced by MITPro are very important to know the real status of the pipe in the well. MITPro has therefore been widely used in casing and tubing inspections in L & TD – VSP. These cross-sections combine with plots, produced by WellCAD and MITView software and are the most effective ways of showing pipe status.

Some pictures below were taken from the casing and tubing inspection results.  Data source was recorded by MIT (24,40,60) tools in White Tiger oil field.

  • In this case, the casing was strongly deformed
  • This image illustrates that the casing was parted.The measured value from all of fingers exceed the nominal outer radius of the casing
  • Solid material adhering to the inside of pipe


          One of the most effective ways of understanding the condition of a well is to produce 3D images. To achieve this, we use a package called MITview.

This powerful presentation package uses the ASCII files of data recorded by an MIT to produce 3D images on a PC screen. These images are under user control and can be manipulated to give a view that best suits understanding the nature of a feature. All the views use a combination of false colour and position to give pictures where diameter changes are shown as variations in colour & shape. During MITview use the initial visualisation generated is normally a view straight down the well; the result is an image similar in appearance to that seen when using a Downhole Video Camera. The difference is MITview has no problem with well fluid turbidity and additionally provides a quantified output. On screen controls provide the ability to add a number of useful measurement aids. The value of each arm reading can be displayed enabling dimensioned cross-sections to be examined. A grid of nominal O.D. can be superimposed, this allows excursions that are probable penetrations to be rapidly identified. "Whiskers" can be automatically drawn to represent anomalies in a vector like form with lines representing the magnitude and direction of a feature.


While views down the well are very informative, MITview can be used to allow the operator to look at features from different directions. Full control of the displayed image allows it to be angled, rotated, lengthened etc. This often makes the understanding of a downhole problem easier. Longitudinal sections are also available.


           MITview users are able to produce a CD for their customer with the data  fil  e  s of a particular job together with an operating version of the program. This allows the engineer responsible for the well to run MITView and examine the data himself

           Exported images can be used to produce hard copy pictures suitable for use in written reports, for example the BOP shown on the right. 

Some pictures below illustrate this software application in Vietsovpetro L&TD. Data was recorded by MIT (24,40,60) tools in White Tiger oil field.
