What’s New in GMI • Caliper™ v. 2.0       

Improved Import and Export Capabilities

•  GMI•Caliper can now process LAS files with angular parameters (HAZI, DEVI, P1AZ, RB) given in radians I instead of degrees.

•  GMI•Caliper can now import auxiliary curves from LAS files (File -> Auxiliary Curves -> Import ->LAS Files…). As before from the ASCII File/Clipboard importer, up to two auxiliary curves can be imported.

•  When loading LAS files (File->Open…) in GMI•Caliper, the dialog window for curve selection allows specifying individually whether a particular curve is either a caliper or a radius. In previous versions the program always assumed caliper for 4-arm data and radius for 6-arm data.

•  Similarly, the Caliper Data Importer (File->Import…) allows the user to specify if data columns are calipers or radii (two radio buttons at bottom).

•  When reading Caliper data from LAS files (File->Open…), the dialog window for curve selection has a new option to Create Caliper files .hdr & .ca4/.ca6. This allows the creation of Caliper files which was so far only possible in case of importing data by the ASCII importer (File->Import…).

•  In previous versions of GMI•Caliper an error message appeared in case LAS files had insufficient definition of bit size (value or unit were missing or incorrect). In Version 2.0 a dialog window opens automatically to enter bit size manually. In addition, in case some of the required parameters have undefined units in the LAS file, an error message with explanation will appear.

•  In case of 6-arm data the ASCII output file now additionally list Cmax, Cmin, Ac and Sc.

•  Files .hdr/.ca4/.ca6 created from an ASCII file (through File ->Import…) use the same depth unit as the original imported file (before depth unit in feet).

•  The criteria for the breakout selection (Tools ->Filter Breakouts…) can now be saved into a text file *.fil by using the new Save button. Later the filter settings can be re-loaded by using the Load button. The user can return to default settings by applying the Default button.

Improved Communication between GMI software - Reading & Writing XML

•  GMI•Caliper can now import zipped XML files from other GMI applications. Data exported by GMI•PressCheck™ can easily be read into GMI•Caliper using the “Open XML Files…” option under the “File” menu (Fig.1).

•  As an extended export capability the >Save To< pop up menu at the bottom of the Breakout Direction window (Fig. 2) offers the export of “XML File…”. This allows saving breakouts into a XML file for easy transfer to other GMI software. This XML file can for instance be loaded by GMI•WellCheck™ in order to compare predicted vs. observed breakouts in the Check Mud Weight mode.

Additional Analysis Plots

•  A new Hole Size Plot (Fig. 3) has been implemented (Plot->Hole Size). This plot provides the user with a better understanding for the hole size and shape. The user can rescale any of the plots by clicking on desired scale and defining new axis limits in a dialog window. Printing from the File menu produces an exact copy of the window (File->Print).

New Tools

•  GMI•Caliper can now display input data and results in both TVD and MD depth units.

•  In any depth GMI•Caliper displays the exact values of the input data and the analysis data (for 6-arm caliper) by left click of the mouse in the desired plot.

•  The bit size can now be changed within the GMI•Caliper program by using the new menu item Tools ->Modify Bit Size…

Improved Appearance

•  All depth scales in GMI•Caliper now have a fixed format instead of scientific notation (for example, 20000 instead of 2.10^4).

•  Up to this update of GMI•Caliper, the Input Data window displayed P1AZ, RB and HAZI only if the particular parameter was delivered by input file (two of the three parameters are obligatory).

•  Vertical wells default to the geographic reference system (and P1AZ), horizontal well to the wellbore reference system (and RB).

•  Labels such as “TVD [feet]” were added to the depth axis of the three-dimensional view of wellbore trajectory (Plot -> 3-D View).

Improved Scaling Capabilities

•  All depth-based plots (Plot ->Input Data, Breakout Direction, Analysis) have a new option to change the scale of any horizontal axis.

•  GMI•Caliper now remembers the scale settings so that its definition does not have to be repeated for each newly generated window.

•  Default horizontal scales are either fixed (for example, [0,360] for P1AZ/RB/HAZI) or they are automatically set to [Min-5%(Max-Min),Max+5%(Max-Min)] in case of variable scales such as calipers.

Breakout Filter Criteria

•  The window for the Criteria for Breakout Selection (Tools -> Filter Breakouts…) is redesigned for both 4-arm caliper data and 6-arm data.

Miscellaneous

•  The manual for GMI•Caliper is now provided as a .pdf file instead of the previously used CHM files (Help ->Caliper Help).

•  Release notes and manual are now accessible through Start ->All Programs ->Geomechanics International ->GMI Caliper.

Bug Fixes

•  A bug is resolved which occurred when calculating the average breakout direction for some .las files with undefined hole azimuth HAZI.
