TS V7.234 30 September, 2011

TS V7.234 - 30 September, 2011

IMAGELog -Lithology/Facies track - we have added a curve source toggle to allow the control curve to be obtained from the alias list or project curve list as well as the individual well list. This also necessitated a rearrangement of the interface window for this track.

IMAGELog -Lithology/Facies track - added support for multiple facies/lithology files in the lithology/facies report table.

IMAGELog -Lithology/Facies track - fixed a bug with using non standard colors in the component definition files.

IMAGELog - Color Coded Track - we have fixed a crash that could occur when using this track in 'hour glass' mode and when the overlay curve display range excluded any color coding within the hour glass area.

IMAGELog - Stratigraphy track - made the WEIGHT and STYLE values for an entry be active so that the box around a stratigraphic unit uses those settings. In the past this always used a line weight of 1 and a solid line style.

IMAGELog - Stratigraphy track - added ability to choose track title orientation if standard header is off.

IMAGELog - Interval Graphs - added report of min, max and average vug area if using the VUG file in this track. Also reports this data in the Pick Data report option.

Formation Viewer - We have added a second breakout file, so now there is Breakout File A and B.

Formation Viewer - Picking Vugs. - the vug area is now computed and stored in the .VUG file when you define a vug shape.

Formation Viewer - We have added support for 4 caliper images. This assumes the calipers are independent of each other and at 90 degrees apart.
Formation Viewer - fmvtool.v70 change. We have made the default depth of investigation for the OMRI tool be 0.9 inches.

Petrophysics - Curve Utilities. We have added a Block by Interval capability. It is under the 'Bedding' tab. This allows a blocked curve be be created based on depth zones in one of several auxiliary  files.

Petrophysics - Curve Utilities - Merge Curves. The default merge method can now be set be a setting. Contact support for help with this if desired.

Import - Geopolitical - You can now specify a line weight setting when importing SHAPE files.

TS V7.233 24 September, 2011

TS V7.233 24 September, 2011

General - a problem with using custom colors has been fixed.

DLIS Export - well constant export can now be turned off when creating a DLIS file.

DLIS Import - the handling of incoming coordinates has been improved to better protect existing well coordinates.

Petrophysics Crossplot - an issue with the crossplot scales being incorrect if entering distly from the power bar under certain circumstances has been addressed.

Dip Analysis - a power bar option has been added to toggle between strike and azimuth mode when displaying rose diagrams on the stereonet display.

TCL - support for the string "!=" has been added to IF statements as an option for "not equal". The old '#' is still valid too.

Sonic Waveform - computations for semblance and slowness taper has been improved.

TS V7.232 8 September, 2011

TS V7.232 8 September, 2011

General - the resolution used in depth shifting (for other than image data) has been improved to exactly honor the depth points used for shifting.  Previously depth shifting adjusted to the nearest depth increment value for the well.  Image data is still shifted to the nearest depth increment, which usually is at a high resolution.

IMAGELog - a text justification problem with facies comments has been fixed.

Borehole Imaging - a problem introduced in version 7.228 involving left and right pick truncation from the right click menu has been resolved.

TS V7.231 1 September, 2011

TS V7.231 1 September, 2011

Borehole Imaging - CAST tools are now supported as a distinct acoustic image type.

LIS Data Loading - a problem where small data values were incorrectly set to NULL values has been corrected.  This problem was seen in CMI data loading operations.

Mapping - a problem with IMAGELog template plotting (on maps) has been resolved.  The problem occurred when a map pick column was present in the template used, and a map pick set was in use.

DLIS Data Loading - SCMI data loading support was added.

Petrophysics - netpay reports can now include information from the IHD well header files via the 'npheader.v70' control file.

Petrophysics - a problem with the Z axis display range when creating a sequence of plots has been resolved.

TCL - added a subroutine called TESTUNITS to check a curves units. See Help for details.

TS V7.230 18 August, 2011

TS V7.230 18 August, 2011

General - an option has been added to disable the MD depth warning in Correlation that appears when the depth reference is set to MD.  Please contact TerraStation support if you need help with this customization.

Formation Viewer - image statistics can be computed within a vug feature.

Auxiliary Data Loading - a generic pick type or subtype can be specified when loading planar picks from external sources.  Thus one may load pick files that do not contain this information.

Mapping - a problem with deleting map points has been resolved.

Edit Picks/Zs - support has been added for displaying picks in TVDSL.  This option is also available for pick values in IMAGELog displays.

Curve Properties - Functions - a problem with loading a value over a block of curve data has been resolved.

TCL - a problem accessing core data via the COREINFO subroutine has been fixed. It would retreive the preceding value to the one requested.

Histogram - statistical values computed on raw data when displaying histogram on logarithmic basis.

TS V7.229 4 August, 2011

TS V7.229 4 August, 2011

General - Fixed an issue with Image File 21 being treated as if it was a Core Data file. Occurred when we expanded the number of image files from 20 to 30.

General - Color Maps - Improved issue of sometimes being prompted that color map is 'read-only' when changing color maps, but not actually edting them.
Formation Viewer - Added a new Pick File type for vugs (represented by polygons). The vugs must be less than 180 degrees in extent and the polygons are currently limited to being up to 8 sides. The auxiliary well file has a ".VUG" extension.
Input/Output - Added some additional Pathfinder image mnemonics to the Auto-Image loading function in the LAS Image Loader.

Input/Output - the LAS Loader will now attempt to extract the TOOL ID (API info) sometimes found on the lines containing the curve name and units, and store it in the Tool ID filed in the curve properties.

Input/Output - LAS Loader. Allow a stratigraphy merge for same intervals.

IMAGELog - Hole Shape Track. Fixed an issue with the TVD display of the 'Draped Image' option. Also made the 'Amplitude' control available for full circumference images.

IMAGELog - Color Coded track. A new 'Clip' option has been added. 'Hour glass form' will display the Overlay curve in a 'back-to-back' display with color coding between the curves.

Petrophysics - Crossplot. Fixed a problem with the Zplot color key if the Z curve is on a logarithmic basis.
Curve Splicer If the curve properties -  description, company, and units - are of the same type then these attributes are now passed to the output curve.

TS V7.228 22 July, 2011

TS V7.228 21 July, 2011

DLIS Loading - file assignment for sonic waveform data has been improved for better consistency of data organization.

Pick Data Options - a new option has been added to the computations available for linear features.  The new option is the "Linear Feature Direction" option.  It represents the azimuthal "direction" of the linear feature, in degrees constrained from 0 to 180.  This is equivalent to the old "Linear Feature True Azimuth" option.  It is the eastern half compass direction, looking down from above, that the feature points towards.

The True Azimuth option now shows an angle from 0-360, which is the compass direction, looking down from above, from the borehole center to the center point of the feature.  This is the same as the breakout option of the same name. It can be used to indicate direction for features which do not extend through the borehole.

For plotting purposes on dip displays, under both these options a dip of 85 degrees is assigned.

Note: previous IMAGELog templates which stored one of these options may not work as expected since the numbering of the options has changed.

Petrophysics - the decimal precision in Multiple Linear Regression has been improved for small numbers.

Petrophysics - the Archie equation constants A, M, and N are now included in multiwell crossplots.


TS V7.227 14 July, 2011

IMAGELog - the curve shading legend in plot files has been improved.

Plotting - a PostScript issue having to do with a narrow depth track has been fixed.

Auxiliary Well Data Loading - the "rank" can be set from the panel when loading stratigraphy.

Correlation - a problem retrieving saved cross sections with more than 20 wells has been corrected.

Sonic Waveform - the slowness range is no longer limited when muting semblance.

Sonic Waveform - fast and slow semblance computations must be set up explicitly by the user.

Mapping - grid handling has been improved after importing outside map grids.

Petrophysics - probabilistic netpay results can now be sorted by thickness.

DLIS Data Loading - SWF file slot assignments have been improved to better standardize the location of specific waveform types.

Data Loading - a problem with the "standard name" file, tlstdnam.v70, has been fixed.


TS V7.226 7 July, 2011

TS V7.226 6 July, 2011

General - the startup sequence for TerraStation has been changed to eliminate the "splash screen".  This is due to security problems under some Windows firewall settings.  A few users had changed the Target in the startup icon to work around this problem.  Beginning with this release, if you had implemented the work-around, you will need to return it to the original system.  We apologize for the inconvenience.

Borehole Imaging- the default depth of investigation has been set to one half inch.

Sonic Waveform - muting for semblance calculations has been improved.

IMAGELog - text display in comment tracks has been changed to prevent words being split.

IMAGELog - a potential crash condition in an interval graph track has been fixed.

Dip Analysis - the data source for lithology/facies columns can now be controlled by the user.

True Vertical Depth - the line display parameters for the borehole trace can now be controlled by the user.

Petrophysics - a problem with curve normalization when using interval file zones has been fixed.

TS V7.225 16 June, 2011

TS V7.225 16 June, 2011

Sonic Waveform - Semblance - the semblance algorithm now allows a larger arrival window to be specified.

Sonic Waveform - Data Control - compressional, shear and density data (DTC, DTS, RHO) can be used to compute rock properties.  PR, YME, KMOD, UMOD, VPVS are created as output curves.  This computation takes place over the current depth interval.

Petrophysics - Crossplot - a key has been added to the color-contour map crossplot display.

Plot Output - PDF - we have improved font geometry to allow for better text justification in center and right justified text strings.


TS V7.224 08 June, 2011

TS V7.224 08 June, 2011

Borehole Imaging - "Bent Hole" logic has been enhanced to improve pick representation in horizontal borehole environments.

Sonic Waveform - an optional window can be used to compute the primary anisotropy computation.

Sonic Waveform - a "re-compute" option has been added to permit users to revise the relative angle and other calculations from the original data.

Petrophysics - Bar Graph - up to two values can now be plotted on a whisker plot.

General - a string limitation (potential crash) in IMAGELog header displays has been increased and made more robust.

Dip Analysis - depth based cumulative dip plots can now display lithology and facies track.

Dip Analysis - one may now compute and display a depth from intersecting lines drawn on the cumulative dip plot.

Borehole Imaging - a problem with extending the dip and azimuth values properly (to the bottom of the interval) when using the "Subtract Variable Structures" computation has been resolved.

TS V7.223 01 June, 2011
