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 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.)

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.

ASCII Log Data Loading - some potential memory problems leading to a TerraStation crash have been fixed.

TS V7.200 19 November, 2010

Sonic Waveform - an option has been added to clear any existing semblance computations.

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.

Petrophysics - curve handling has been improved in multi well cluster analysis.

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

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.

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 - 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.

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.

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.

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.

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.

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.

This function can be used for both interval files and stratigraphy files.

DEXTR - thickness computations now always use the correct endpoint strategy and cannot be overridden by the user interface setup.

DEXTR - because the storage for zone interval endpoint handling is unavailable within the map Dextr definition, zoned Dextr sequences do not provide the "Save Command" option. Zoned Dextr operations must save results to a "Fixed Value" Z variable. You can re-run the zone analysis and save the values back to the original Z if necessary.

DEXTR - zone operations in Dextr can only work if Z variables are being used for the zone extents. Error checking has been improved so the user is warned if there is a problem with the zone setup.
