TerraStation Version 7.360 21 January, 2015
IMAGELog - an errant facies interval line that might appear in an IMAGELog track header has been removed.
Correlation - the current datum for a stratigraphic section is now remembered when inserting or deleting a Z variable.
General - the system for managing the ID number for stored log constraints has been improved. ID numbers could sometimes be reused, preventing access to the duplicated constraint ID.
Sonic Waveform - frequency dispersion calculation popup plot can now be "auto-run". Users should first set "use saved values". This option permits a video capture of the sequence.
Formation Viewer - a problem when setting the "slot name" under Tool Attributes has been resolved.
Data Loading - the LAS data loader attempts to auto-detect orientation data when loading images.
Dip Analysis - a problem where pick filters were not applied has been fixed.
Mapping - some issues with the display of rose diagrams on a map have been corrected.
TerraStation Version 7.359 15 January, 2015
Sonic Waveform - an option to compute Backus upscaled moduli, density and sonic curves has been added. It is on the Data Control - Save Rock Properties panel.
Petrophysics - Curve Utilities-Filters now offers a time based filter for upscaling of curves using either a TWT or OWT curve for the time to depth conversion. The time filter must be supplied as an ASCII file.
Data Loading - the Auxiliary Data loader can now load show symbols into the General Symbols file.
Data Loading - images loaded via the LAS loader can now recognize sequences of curves as the image, rather than requiring explicit definition of each button as before.
Data Loading - the program attempts to auto correct longitudes during loading to reduce the possibility of incorrect sign errors.
Data Loading - users may now specify the incoming data increment in the LIS loader when loading images. LIS data may be unable to determine the image increment with sufficient accuracy if floating point values are used for incoming depths.
Synthetic Seismic - an obsolete floating point format for SEG-Y files used by Kingdom can now be exported from TerraStation.
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.
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.
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.
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".
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.
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.
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.
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.
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.
