TS V7.208 3 February, 2011

Sonic Waveform - track muting availability has been expanded for various sonic waveform displays and data handling options.

Petrophysics - the Echo curve data display now allows the depth sampling to be coarser than the actual depth increment.

Well Data Export - if only a single well is selected for export, the current well collection is not modified.

Petrophysics - Crossplot - the fixed point of the Fixed Point Regression is now retained after batch plotting.

Petrophysics - Merlin - an error with the multiple linear regression report table involving the statistical summary has been resolved.

DLIS Data Loading - the assignment of sonic waveform files has been improved, especially when loading multiple sonic waveform data sets.

TS V7.207 27 January, 2011

Correlation - an option has been added to reset the template for a well in a cross section to the default template.

Sonic Waveform - a curve can now be imported into a sonic waveform trace.  This can be used with an external DT curve to guide the calculation.

Sonic Waveform - a depth shift option has been added which can be applied to sonic waveform data.

Sonic Waveform - "on-the-fly" semblance computations can now be done to reduce the amount of storage required for computed results.

DLIS Loading - a problem in the method for assigning output sonic waveform files has been resolved.  Also the system for capturing sonic waveform constants has been improved.

TVD - additional checking of incoming directional survey files for the well name or UWI.  The extra form takes the first part of input file name until an underscore character is encountered and uses this as the well name (or UWI) for matching purposes. It ony uses this after first trying to use the entire filename as the well name or UWI.

Curve Splicing - a new report capability has been added. It details what curves and what intervals of those curves were used to generate the spliced curve.

Well Collections - a problem with the new system for storing well collections as seperate files has been fixed.

TS V7.206 20 January, 2011

General - well collections may now be saved using a method similar to an IMAGELog template.  This permits easier sharing of collections between users of the same project. The default method has not changed. Activating this new approach requires an addition to your user_def.sbi file. You can contact TERRASCIENCES or look in the online help under the Well Selection & Collection chapter for information on how to do this.

Well Data Management - users may now modify the curve properties for multiple curves within a single well.  (From the right click menu in Well Data Management.)

Petrophysics - some issues with creating an array curve from columns of another array curve have been resolved.

DLIS Data Loading - errors in unpacking packed PWFX curves containing sonic waveforms have been corrected.

Petrophysics - button labeling in curve utilities has been improved so that current data selected is better identified.

TS V7.203 28 December, 2010

LAS Export - the handling of a TVD curve which is not fully populated has been improved.

Sonic Waveform - the default Baker dipole time step is now 36. Previously it was 40.

General - a problem with the Edit Tops/Z's table which caused duplicate map well points to be created has been fixed.

TS V7.202 8 December, 2010

Sonic Waveform - displays have been improved when the waveform depth increment is smaller than the well depth increment.

DLIS Data Loading - a rare problem wherein values at a given depth might be skipped has been fixed.

Map Data Loading - a problem with loading map data into previously deleted points has been resolved.

Geopolitical Data Loading - A problem with loading SHAPE files has been addressed.

Correlation - an issue with "custom" well IMAGELog templates being carried over to a new section has been fixed.

Dip Analysis - Depth interval settings for stereonets now properly reflect the selected stratigraphic "rank" when specifying the depth interval from the stratigraphy display.

Previous Release Notes

TS V7.201 1 December, 2010

Borehole Imaging - an option to rescale an image into the zero to one data range, based on a cumulative distribution, has been added. This operation can be accessed on the Analysis tab as "Rescale to 0-1". Please note that your original data will be lost in this operation.

Note that the depth interval definition controls identify the interval over which the cumulative distribution data is computed. The operation will change the image data for the entire image.

Waveform - One can now patch a DT computed curve on a semblance track. Pick up to 3 points. First click on the curve to patch and the initial depth limit. The second click shows the path to follow. The (optional) third click identifies the other depth limit. See the help for details.

Waveform - a "Truncate" option has been added to the table data editor. This sets extreme values to the extreme of the neighboring waveforms.

Waveform - a right click frequency dispersion crossplot display option has been added. This uses a 1.5 kHz width rectangular band pass filter. The step is 0.1 kHz.

Waveform - a checkbox for semblance merging has been added. Muting must be on for this option to work.

Waveform - the absolute maximum of the slowness has been increased from 500 to 1000 us/ft. This is still limited by the number of samples in the reciever arrays.

Petrophysics - the standard deviation is now included in histogram statistics reports.

IMAGELog - several new data management options have been added to curve displays. One is that you can now right click on a point and "Copy Values to Clipboard". This captures the depth and curve values at that depth into the Windows clipboard.

IMAGELog - Another new right click option is to left click on a curve, then drag a zoom box and right click. You may "Copy a Curve", which picks up the trace of the curve you clicked on to begin. Then you can paste that section of curve into another curve, or access one of several other options by right clicking again.

AUX Data Loading - DEX format biostratigraphy data can now be loaded.

Petrophysics - a problem with the Welex Matrix Conversion correction has been resolved.

Dip Analysis - stratigraphy names now display properly on walkout plots.

DLIS Loading - a "heap error" condition has been resolved.

DLIS Loading/Export - the null value for sonic waveform data has been fixed at -999999.0. This allows proper handling of data which may include as a legitimate value the standard null value of -999.25. This may create problems if other programs use a different null value.

IMAGELog - pie charts in lithology/facies tracks can now display percentages alone, or do combined color/pattern displays.

IMAGELog - the option to click on a curve and see the numeric values in curve tracks is now active when in pick edit mode.

TS V7.198 28 October, 2010

IMAGELog - a new biostratigraphy track type has been added to IMAGELog. Please refer to the help manual for more information on how to use it.

AUX Data Loading - all the engineering file (.ENG) data types are now supported.

DLIS Loading - when loading sonic waveform or image data, the program now presents a parameter table listing. Users should review this listing to ensure that the proper instrument constants have been loaded. E.g. tool spacing for waveform tools. As mnemonics become standardized, we can configure the loader so it retrieves these values automatically.

Well Collections - one may now search the project and build a collection based on the presence or absence of location coordinates.

TS V7.196 14 October, 2010

Correlation - the right click popup menu has been modified somewhat. A new "Well Properties" option is now included when a well is clicked on in cross sections.

1. A "data type" toggle has been added to tell the program to work in dipole anisotropy mode.
2. Fast and slow semblence computations are now saved in an SWX and SWY file which can be displayed.
3. Stored slowness curves are monitored to make sure that their slowness range does not intersect that of any other slowness curve.

Sonic Waveform - the workflow for performing dipole anisotropy has been modified. Please check the help file for more information.

Petrophysics - Crossplot - the number of frequency plot bins can now be configured in crossplots. The maximum it can be is 500.

TS V7.194 30 September, 2010

IMAGELog - options have been added for controlling the orientation of the header text in several tracks that did not allow this before.

IMAGELog - folded curves can now "double" fold. That is, if the curve values go off scale on the folded or wrapped scale, they will show up on a third scale.

Correlation - a possible crash when the cross section contains more than twenty three wells has been fixed.

General - a problem wherein the table went blank if deleting multiple rows in an interval file has been resolved. No data was lost, but it was a little confusing.

Data Export - the DLIS file export utility now supports the export of sonic waveform data.

 

TS V7.193 23 September, 2010

IMAGELog - blank tracks can now have vertical headers.

General - several issues related to the new compiler have been resolved. These cause error messages to be thrown up for tasks which have worked correctly in the past. We apologise for the inconvenience, but these messages should enable us to eliminate the mysterious, untraceable crashes which occasionally have occurred in TerraStation.

IMAGELog - a crash in the draped image form of the hole shape track has been fixed.

Sonic WaveForm - slowness parameters are now saved with the sonic waveform data, so they can be retreived for later use with the particular data.

Borehole Imaging - a problem with image depth shifting (introduced in 7.192) has been resolved.

Well Log Export - depths are now written to 4 decimal places, which should reduce extraneous digits being appended at the limits of numeric precision.

Petrophysics - when making a multi well histogram, a well may be selected for highlighting on top of the overall histogram.

IMAGELog - we have added an AUTO keyword option to the TABLE ZONES command in IMAGELog headers. This allows only zones within the current depth interval to be displayed in the table.

 

TS V7.192 16 September, 2010

Formation Viewer - Pick Export - borehole image picks can now be exported in a LAS-like format for use with FracMan. Note this is not a standard LAS format and may not load into other software packages, including TerraStation.

IMAGELog - the number of curve values seen on the status line in "interrogation" mode has been increased.

Stereonet - the "mirrored" azimuth constraints for azimuth displays is now shown.

Petrophysics-Crossplot - a problem with resetting curves when selecting a well from the Select Well button has been fixed.

General - "sub-parallel picks" now use a polyline for a more detailed display. Sub-parallel picks are those that are nearly parallel to the borehole track.

Petrophysics - EQUUS now functions for curves that are not sampled on the main well depth increment, that is 'fast' curves. Equus does not function with irregularly sampled curves.

TS V7.190 25 August, 2010

Dip Analysis - a "mirror" option has been added for azimuth constraints.

Borehole Imaging - a beta version for a new system which saves picks in "bent" holes has been added. Whether the system is used is controllable via a checkbox on the "Pick and Breakout Options" panel. We welcome feedback on the new feature, especially on whether performance is adequate.

General - when displaying ASCII files, tab characters will be displayed as "[TAB]". This makes it easier to determine the layout of incoming ASCII data files.

General - a maximum of 4 gigabytes for a well file has been established.

Borehole Imaging - a problem with saving the angle offset in Dual OBMI images has been corrected.

Multi-Z Echo Edit - when editing Z values, the window "focus" will remain on the edit window to permit multiple edits. In IMAGELog, previously it would shift to the curve display as it was redrawing the picks.

Data Loading - an "alias" system for identifying company names during loading has been created. The configuration for this system can be found under ASCII Editing/ Labels/ CURVE_COMPANY.

General - parameter files will now initialize automatically when setting parameters from a screen display. E.g. when setting a geologic parameter from a histogram.

Dip Analysis - users can now display data on the Azimuth vs Dip plot using a -180 to 180 range.


TS V7.188 05 August, 2010

Borehole Imaging - the accuracy of saving picks that are nearly parallel to the borehole has been improved. This system relies on the following:

1. The method comes into effect after 5 pick points and if
relative dip is over 80 degrees.
2. It requires the tvd, xdev and ydev channels to be populated
3. If there is a discrepancy between surveys, be sure to use
the image file data to run the TVD calculation.

General - TerraStation now has a list of "curve companies" to help keep track of the history of each well curve.

Borehole Imaging - We've added support for the slim FMI tool type.

Stereonets - curve shading cuttoffs are saved with the setup.

TCL - a problem with the ELSE condition in an IF statement has been resolved.

Formation View - a histogram option has been added to formation view tracks.

Formation View - a problem recomputing image orientation has been resolved.

Formation View - symbols are now retrieved correctly for truncated picks.

Mapping - a error message about a missing "BTT" file has been turned off. This message was innocuous and did not indicate a real problem, but it was irritating.

General - data can now be "pasted" from the copy buffer into the end of Auxiliary data files.

TS V7.185 30 June, 2010

IMAGELog - The location of core image photos can now be recomputed from the Driller's Depth and Offset values. Core photos are positioned using the Top and Bottom depths. The Driller's Depth is retained only for reference. However, this option permits you to reposition core photos so the top is moved to "Driller's Depth + Offset".

IMAGELog - a lithology/facies key can now optionally be displayed in a seperate window.

IMAGELog - The lithology/facies track now has an option to remove thin beds. This is found under the Data Operations button. Any beds below a specified thickness can be removed using this option.

Borehole imaging - Pick Editing - the pick quality values can now be configured for keys 1, 2, 3, or 4 to user specified values. They default to 20, 40, 60, or 80% quality initially, with 0 always being 0 and 5 always being a quality ranking of 1.

Data Loading - the LAS loader can now add orientation data from LAS files to an existing image.

Dip Analysis - a lithology/facies column can now be added to stereonets in dip analysis using the Display Preferences - Strat/Lith/Facies Track tab.

Well Collections - a collection of wells can be created based on the presence of the various auxiliary files. This can be used to obtain a list of all wells in the project which have pick files, for example. (Or all which don't.) This can be useful for data management purposes.

TS V7.184 10 June, 2010

Plotting - the ability to move JPEG images inserted in TerraStation plot files now functions correctly.

TCL - some additional warning messages have been added.

Petrophysics Histogram - the "mean" and "mode" are now displayed when doing multiple plots per page.

Petrophysics Equus - NULL handling when constraints are active has been changed. Previously, when doing an Equus calculation, if a constraint was active and the depth failed the constraint, a null value would be written to the output curve. This has been changed so that whatever value is present in the output curve is left alone, with no change.

TS V7.179 21 April, 2010

Plotting - a TIFF inversion option has been added.

Plotting - support for "bigTiff" formats has been added. This is an expanded TIFF format for large drawings. Plots which are small enough that they do not require the expanded format are drawn in standard TIFF format.

Plotting - a problem with incorrect plotting of symbols in some circumstances has been resolved.

TS V7.178 8 April, 2010

General - when drawing finely sampled curves on screen, curves are subsampled to improve display performance. A problem with this new technique, introduced in 7.177, has been resolved. It would not affect most users. The error resulted in inappropriate depth shifting. This happened in screen displays only, and only at scales higher than 1:240.

General - Curve Source selection support for the recently added 10 additional image file slots now exists.

Sonic Waveform - Brute Force Method - a new method for computing anisotropy angle has been added. It computes semblance based shear for all angles (between 0 and 180) to find the angle where it is fastest.

Plotting - a warning about potential display problems in other software packages has been added for large PDF drawings.

Petrophysics - Netpay - a problem restoring saved net pay setups has been fixed.

TCL - rock elastic properties can now be computed using a TCL subroutine called ELASTICS. See the online help for details on the call.

Data Loading - a problem when merging well data has been corrected.

Borehole Imaging - annotation has been expanded on popup image histograms.

Sonic Waveform - a "band pass" label has been added to the detailed frequency spectrum display.

Sonic Waveform - Slowness - DT Separation. This allows the 'distance' between the computed DTC and DTS to be constrained when using the semblance method. It can now be controlled by the user. Choose either a factor or the Poisson's ratio.

TS V7.175 4 March, 2010

IMAGELog - a new shading legend option has been added to curve track headers. To activate the shading legend option, enter a "Shading Description" under the Display Attributes for the shaded curve. Note that the Curve Name labeling under the Header/Options panel must also be checked.

IMAGELog - track header labeling has been improved, especially for vertical curve labels in track footers.

IMAGELog - a new button option has been added when doing interval control for such things as rose diagrams. The option is called "Remove Gaps". It modifies the intervals so that when the bottom of one interval is within four depth increments of the top of the next interval, the gap is closed. The bottom of the upper interval is moved to equal the top of the lower interval. The change is written into the interval file for subsequent use.

Map Loading - the "One Line Per Z" option has been removed. It should be possible to load this type of data via the normal delimited loading sequence. To load a "One Line Per Z" data file, simply identify the column where the Z name appears.

This should be a more powerful method, since it permits a variety of column configurations and is not bound by column order.

Geopolitical Data Loading - CDF files with mixed case keywords can now be loaded.

Geopolitical Data Loading - support for loading projected coordinates has been improved.

General - some new units and curve mnemonics have been added to the system.
