TS V7.358 - 7 January, 2015

TerraStation Version 7.358 7 January, 2015

Data Loading - NGI image mnemonic recognition now attempts to classify caliper measurement as diameter or radius.

General - a new user interface has been installed the Preferences area. Comments are welcome as this style of panel layout will be adopted in other program applications.

Correlation - the currently active well name is now highlighted (if displayed) and its symbol enlarged on the context map.

IMAGELog - internal logic has been added to adjust the display ranges appropriately for fractional vs. percentage curves.

Borehole Imaging - a potential crash issue when displaying images in Contrast mode has been fixed.

TS V7.357 - 18 December, 2014

TerraStation Version 7.357 18 December, 2014

IMAGELog - a problem with vertical line divisions in stratigraphy tracks, introduced in version 7.355, has been fixed.

Borehole Imaging - an audit record is now kept in the Well Audit file when accelerometer and pad flap corrections are done on an image.

Borehole Imaging - support has been added for the Tucker High Resolution BIT tool.

Dip Analysis - saved configurations will now remember the Dip Data Control - Display Options section settings. eg Quality Cutoff, partial Pick Filter, etc.

Synthetic Seismic - some changes have been made for SEGY output to improve the chance of third party software reading the file.

Synthetic Seismic - wavelet presentation in the header of the display has been improved.

True Vertical Depth - a warning message is now posted if the XDEV and/or YDEV output curves are set to Read-Only.

TCL - COPY_GLP, COPY_INT, COPY_RUN commands - an option (parameter=2) now exists to assign a single parameter file to all wells in a collection. For example, one could assign a standard INT interval file to all wells. This is different than the old copy utility. With this new method, one need only edit the master file for it to be propogated to all wells.

TS V7.356 - 11 December, 2014

TerraStation Version 7.356 11 December, 2014

Sonic Waveform - the table editor for SWF data now includes a depth shifting option.

IMAGELog and Dip Analysis (Stereonet) - control for the displayed pick sets has been enhanced. Users may now explicitly choose to add linear features, breakouts, or vugs to the displayed pick set. Pick computations, if used, will only apply to the primary pick set. Other display options apply in the same way to all active data sets.  Rose diagram displays will use the size control as configured for the primary pick set.

Data Loading - a problem adding a curve suffix name when loading irregularly sampled curves from ASCII data has been resolved.

DLIS Loading - a mislabeled option on the Convenience Tab of the Curve Load Control option has been corrected. This option permits the user to load "fast" channel data in its entirety when loading DLIS data.

General - a crash in well collections has been fixed.

TS 7.355 - 4 December, 2014

TerraStation Version 7.355 04 December, 2014

Formation View - Borehole Visualizer - some work has been added to make it easier to set the view angle. One can now left click on a desired MD as the view centerpoint. A toggle for resolution control has been added. Performance may suffer at full resolution since the entire image is accessed while producing the drawing.

Sonic Waveform - a frequency dispersion tracking option has been added to the right-click menu of Sonic Waveform tracks. If the frequency dispersion has already been computed, performance will be improved by "using saved values".

General - ASCII File Editing - when editing some auxiliary well data files, including the pick files, the depth column is "static" so it will always be displayed even if the table has been scrolled to the right. Depending on the file type, more than one column may be 'fixed'.

IMAGELog - a problem when right clicking to add facies/lithology beds (not terminating properly leading potentially to an extra bed being inserted) has been resolved.

IMAGELog - one can optionally now have a cross-hair cursor rather than an arrow while configuring a track. There is a new Cursor Mode setting on the Track Setup panel for this.

Dip Analysis - cumulative dip and azimuth vector displays now display an "N = " count.

Well Data Management - X and Y coordinates now appear as part of the well data management table.

Data Loading - the LAS loader can now automatically append data to an existing image file.

IMAGELog - one can now edit well stratigraphy data (.STR files) interactively via right click, "grabbing" the top or bottom.  One can also add new entries using the Add Feature menu item.

General - a "preferences" option has been added which initially fits restored IMAGELog template displays to the width of the window. A "Fit Width" powerbar option is also now available.

Sonic Waveform - initial support for the Halliburton Array Sonic Tool and Schumberger Thrubit data has been added.

IMAGELog - a new "length" option allows the user to calculate a selected depth interval. Left click on a curve track, hold and release at the end of the interval. Then right click and select Report Interval to see the distance.

Sonic Waveform - merging sonic waveform files is now possible for the receiver arrays. Several options control how the data is merged. Semblance and frequency dispersion values cannot be merged, but may be replaced if one does a "raw overwrite".

TS V7.354 - 12 November, 2014

TerraStation Version 7.354 12 November, 2014

Correlation - well distances are now displayed correctly after inserting a "pseudo" well.

Petrophysics - Curve Properties - Functions tab. The Copy, Load Fixed Value, Blank Interval and Interpolate options now operate on the current depth interval.

General - a right click option has been added to the curve Status function. Choose Select Curves. A Status table for just the selected curves is generated.

IMAGELog - a saved depth shift can now be applied to lithology or facies files. See the Options tab on Track Configuration for a facies or lithology track.

Borehole Imaging - a saved depth shift can be applied to pick files via a new function on the Functions tab of Pick and Breakout options.

Borehole Imaging - a Pick Key option has been added to the general tab of Pick and Breakout options.

General - when displaying Pick Keys, one may choose to display the key as sine waves, with the appropriate line colors and settings.

DLIS Writing - the mnemonic for image deviation has been changed back to SDEV. (Used prior to TS V7.343.) Techlog is unable to recognise another mnemonic for this, while WellEye insists on the mnemonic DEVI. If you want to export a DLIS file to WellEye, use Curve Utilities to create a curve in the well file named DEVI.

Petrophysics - histograms which use data from auxiliary well files such as button curves from images will now be labeled as to the source data file for the curve For example "Buttn 130[FMS]".

Petrophysics - RFT crossplots have been enhanced to compensate for a deficiency in well engineering data in which units are not stored. Units may be included within parentheses in the X axis title (e.g Pressure (psi)), which will then be used for RFT line gradient labeling.

TS V7.353 - 7 November, 2014

TerraStation Version 7.353 - 7 November, 2014

General - warning messages about "unique well names" are limited to 5 so data loading can proceed without excessive interruption.

Data Loading - the single well LAS/ASCII loader can now match the well data either by well name or UWI.

Data Loading - the Auxiliary Data Loader now has an option to remove extraneous characters from incoming UWI strings.

Data Loading - the Auxiliary Data Loader can now calculate the component index when loading lithologies or facies.

Sonic Waveform - under certain conditions, semblance calculations might not provide updated results for sections of the selected interval. This has been resolved.

Borehole Imaging - some problems when exporting picks after changing wells have been fixed.

Petrophysics - the Hingle Plot has been improved to set the initial value of the matrix point more appropriately for the porosity curve that is being used.

Petrophysics - some issues with Pickett Plot lines and range control have been resolved.

Correlation - a problem when adding a new stratigraphy element to a cross section has been fixed.

TS V7.352 - 22 October, 2014

TerraStation Version 7.352 22 October, 2014

Data Loading - TerraStation now honors loading flags with respect to TVD curves. Previously they might be overwritten despite contradictory user interface settings.

Data Loading - some improvements have been added with respect to comment loading.

Borehole Imaging - initial mnemonic support for the new slimhole resistivity imaging Geologger tool from Robertson has been added. This will be refined as more information about the tool becomes available.

IMAGELog - a problem with the widths of breakout displays in breakout tracks has been resolved.

TS V7.351 - 15 October, 2015

TerraStation Version 7.351 15 October, 2014

IMAGELog - a problem when drawing image file curves containing gaps and skipping over NULLs has been resolved.

Map Data Loading - non alpha numeric characters can be removed from UWI strings during data loading. This makes it easier to match existing wells which may have been loaded from other data sources.

Map Data Loading - the sign of the incoming longitude value can now be reversed at the table stage without reloading the file.

Sonic Waveform - the filter and data limit parameters previously used when computing semblance values now appear in the user interface settings, showing the setup used.

TS V7.350 - 1 October, 2014

TerraStation Version 7.350 1 October, 2014

IMAGELog - Various items of information from waveform files can now be automatically picked up by IMAGELog header files. See the SWF command set in the Header Command Language part of the help.

Curve Splicing - an option to bulk shift curves during splicing operations is now available.

TerraStation Version 7.349 24 September, 2014

Dip Analysis - IMAGELog templates can now be displayed and interacted with as part of a Dip Analysis stereonet display.  A mud log track or second lith/facies tracks can no longer be displayed directly - use a template to do this if desired.

Well Export - LAS - Well Constants to be output can now be specified via a config file called 'wxconst.restrict'.  This file must be in the project folder. See the help for details on use.

Geopolitical Loading - a problem when loading geopolitical text entries has been resolved.

General - a crash condition when accessing Well Properties and in other circumstances has been fixed.  This problem was introduced in version 7.345.
