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.
TerraStation Version 7.348 18 September, 2014
IMAGELog - some problems with title header text in a stereonet track have been corrected.
Well Data Loading - an issue with loading multi-well formation view picks has been fixed.
DLIS Loader - some additional options have been added to the Verification Listing report.
DLIS Loader - contents reports for DLIS files are now stored in the original source folder if it is writeable.
IMAGELog - Z Aliasing can now be used when defining zones bounded by map Z variables in a well stratigraphy track.
TerraStation Version 7.347 10 September, 2014
Dip Analysis - a display issue when using a quality cutoff for dips causing overwriting of text has been resolved.
Mapping - a potential crash condition when using bubble map displays has been fixed.
TerraStation Version 7.346 3 September, 2014
Note: Version 7.346 was not formally released but is included in Version 7.347.
IMAGELog - the clipping for color coded curve displays has been improved at the top and bottom of the window.
IMAGELog - "fast" curves can now be displayed in a color coded curve track.
Image Data Loading - support has been added for Weatherford CMI_S tools. Some additional slow channel mnemonics have been added to the look up system.
Dip Analysis - a second lithology/ facies track can be shown on stereonet displays.
TerraStation Version 7.345 27 August, 2014
Dip Analysis/IMAGELOG tracks - rose diagrams and stereonets can now be optionally drawn without spoke labels. (Spoke labels were added in TerraStation version 7.344.)
Dip Analysis - Azimuth Vector and Dip Walkout Plot - one can now zoom in and out using the mouse wheel (or up and down arraw keys). One can grab and move the display using the left mouse button (use a left click-drag and drop sequence of events).
General - a comment field has been added to lithology and facies group files. This comment can be used to populate the comment field when adding lithology or facies entries.
DLIS Loading - a (usually innocuous) bug which caused the program to show a "repcode error" has been fixed. The repcode errors were in most cases not truly errors.
DLIS Loading - a problem with interlacing for FMI images has been corrected. This caused all previously loaded FMI images to have their buttons swapped. If this error is present, you may correct it by using the button swap option under View/Edit Data.
The problem would reduce the resolution of FMI images, but the image itself would be usable and picks made from it would be valid. In cases where an acceleration correction was done, users should make certain the most current version of fmvtool.v70 is being used. I.e., no old versions of fmvtool.v70 remain in userdata or elsewhere in the system.
TerraStation Version 7.344 20 August, 2014
Borehole Imaging - if the tool type of a Baker tool is changed, the program attempts to reload the appropriate accelerometer and magnetometer curves for QC plots.
Borehole Imaging - image selection lists now mark existing images with an asterisk.
Header and Title Box Editor - sonic waveform header items may now be configured within the Header and Title Box Editor.
DEXTR - a problem has been corrected with the "Fail Constraints" null being lost.
DLIS Loading - a crash condition has been resolved when sonic waveforms files cannot be properly created.
DLIS Loading - users may now create verification listings in batch mode. This permits an easy file inventory method for a folder containing multiple DLIS files.
Borehole Imaging - the polygon used to represent a pick plane in 3D displays can now be chosen from a right click menu when editing the pick configuration file. (tspcktyp.v70) Left clicking on the polygon cycles through the possible shapes.
TerraStation Version 7.343 13 August, 2014
IMAGELog - Automatically rotate perforation symbol annotation in an Engineering Track if the string length exceeds six characters.
Dip Analysis - add spoke labels to stereonet grids if labeling is on.
Sonic Waveform - correct a problem with the anisotropy semblance calculation when some receivers are turned off.
Borehole Imaging - the Caliper QC crossplot now honors any RB offset.
Sonic Waveform - some waveform header information can now be displayed via the HDR track header system. See the online help for more information. Sonic Waveform options will not be available in the Header and Title Box Editor until the next release.
Data Loading - LAS data loading can now optionally ignore lengthy incoming curve descriptions.
Data Loading - depth units can now be forced to be feet or meters when batch loading LAS files.
Data Loading - data can now be appended to image files using the LAS image data loader.
TCL - the AUXCOPY function now maps data to the nearest depth increment when creating a well curve from auxiliary data.
Petrophysics - lithology and facies information may now be used as a histogram constraint.
General - well collection searches now determine the presence of curve data over the interval given in the well collection (Exclude from Collection only). Previously the entire well interval was used.
General - selection lists for available data in some circumstances will now show only existing images.
TerraStation Version 7.342 - 23 July, 2014
Petrophysics - a normalization option has been added to the crossplot module.
General - the display efficiency for large BMP files has been improved.
Formation Viewer - the image QC caliper plot and IMAGELog hole shape plots now handle 8 caliper images.
IMAGELog - ellipse fitting has been improved in hole shape tracks when more than four calipers are present.
IMAGELog - hole shape track ellipses may now be displayed as an overlay option.
DLIS Export - the DLIS exporter has been modified to support export of files to Schlumberger's free borehole viewer, WellEye. This is largely a matter of curve mnemonics, and may not work for all images. If you want to do this and are having problems, please contact TERRASCIENCES so we can fix them
LIS and DLIS Export - a problem with the button order when exporting GeoXplorer images has been fixed.
Formation Viewer - users can now add linear features in a polyline sequence. That is, the second point of the feature can be used as the first point for the next feature. This lets users trace breakouts with multiple line segments.
IMAGELog - the structure profile track now draws the borehole path last so it will always be visible.
Map Loading - the loader has been improved to better ignore mismatches if a UWI is missing during merge mode.
IMAGELog - one can now output a simple curve status report from the interval graphs track.
TerraStation Version 7.341 - 10 July, 2014
General - a WELLNAME keyword has been added to the HDR command file language, to allow well specific text headers to be picked up when plotting in batch mode using the same header control file.
Sonic Waveform - the default order for DSI X and Y dipole T-R1 spacings has been reversed so the X is now the upper.
General - Some new mnemonics have been added for loading alternate orientation data.
General - a problem with the ellipsoid for German map projections has been fixed.
DLIS Loading - the volume of error messages has been reduced for certain error cascades.
Petrophysics - Crossplot - the annotation of TPNH (instead of CNL) has been fixed in a couple of Schlumberger neutron density crossplot overlays.
Borehole Imaging - a problem with the order of caliper radii involving NGI images has been corrected.
TerraStation Version 7.340 - 18 June, 2014
Sonic Waveform - a simple frequency dispersion correction (for semblance only) has been added. This uses a dispersion lookup table for the correction.
Borehole Imaging - a simple ex-centering correction for CMI images has been added. This assumes the upper tool arms are centered. They are used to define the ellipse.
Map Loading - has been improved to better preserve existing map limits when incoming data posts within them.
General - a units conversion for m/hr has been added. It is used by the image data loading for converting cable velocity.
TerraStation Version 7.339 - 11 June, 2014
Borehole Imaging - order and high and low frequency cutoff values can now be supplied by the user for the Butterworth filter used in the acceleration correction.
DLIS Export - a complete set of Dual OBMI channels is now written to an output DLIS file.
DLIS Export - the control panel has been modified so that it fits properly on smaller computer displays.
TerraStation Version 7.338 - 04 June, 2014
General - some additional geochemistry curve categories and descriptions have been added.
IMAGELog - the program attempts to remember the plot scale after accessing header options when creating a plot.
IMAGELog - if the screen display of IMAGELog is rotated, the fill patterns are also now rotated.
TCL - the window title description when processing wells better describes whether the program is in single or multi well mode.
Petrophysics - a problem with curve selection in the net pay module which was introduced in version 7.337 has been corrected.
Sonic Waveform - sonic waveform displays are now subsampled when displaying large intervals for performance reasons. This happens if the wave frequency is less than .5, or if more than 2400 depths are included per inch of depth display.
Sonic Waveform - a horizontal line has been added to improve accuracy when DT guide editing.
Sonic Waveform - an initial version of the C66 modulus computation for transverse isotropic within perpendicular borehole situations has been added.
Sonic Waveform - a preliminary version of the Butterworth filter for sonic wave form processing has been added.
Note: normally this is a two pass filter, first low then high, but if low pass cutoff is 0, no low pass filter will be done. If the high pass cutoff is 0, no high pass filter will be done.If using an alternate filter for anisotropy, the filter will be same general type as that defined on the Data Control tab. The three Butterworth parameters are order (exponent), high pass cutoff and low pass cutoff.
