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.
TerraStation Version 7.337 - 21 May, 2014
Sonic Waveform - Semblance - When stacking transmitters, one can now use a multi-shot average or sub-array computation when working in multi-shot mode.
Sonic Waveform - an option has been added to declare an alternative bandpass filter for use in dipole anisotropy.
Sonic Waveform - the anisotropy raw relative angle and final relative angle curves are now stored separately.
General - some new patterns have been added.
Petrophysics - curve aliasing can now be activated when running net pay analysis.
General - a problem with the IMAGELog header editor that was related to displaying the entire header if the header was wider than it is tall has been addressed.
TerraStation Version 7.336 - 14 May, 2014
Borehole Imaging - an "All Pairs" option for auto picking has been added.
Data Export - the MD value is always included when outputting auxiliary data, even in TVD mode.

DLIS/LIS Export - RMI tools now export the button arrays with the original mnemonic set, i.e K001 to K144.
General - the Scout Ticket editor now has a right click option to "clear" a Z variable. This sets all values for the Z variable to NULL.
General - the pattern editor can now support sixteen by sixteen bitmaps.
TCL - a problem with the PICKINFO command has been fixed.
Mapping - a new EQUUS type function has been added to the map module to permit advanced Z calculations.
TerraStation Version 7.335 - 07 May, 2014
Mapping - the map title now displays the current Z variables - first the Z used to position the well spots (the reference Z), followed by the grid Z (contoured Z, if different).
Mapping - the contour interval can now be displayed if using the HDR system to create a custom map header. The commands ZCONT and CONTOUR_INT have been added to the HDR layout system to support this.
Data Loading - ASCII forms of data loading now support the possibility of eight calipers when loading images.
Borehole Imaging - the pair of opposing pads auto picking method has been improved for better results with six arm dipmeter devices.
Sonic Waveform - the magnetic declination correction is now remembered and stored with the data file.

General - problems with removing map duplicates and "Link, Add to Map" in Map Data Managment have been fixed.
IMAGELog - a "lines only" form of the pick key is now available.
IMAGELog - an option to display lithology or facies patterns on a black background. The initial version should be used only with the primary colors.
IMAGELog - an initial attempt at a lithology/facies group file editor has been added.
IMAGELog - Lithology/Facies track. The thickness histograms can now be scaled independently and control over the number of bars has been added.

Dip Analyis - the key positioning for azimuth vector plots for detailed dips has been improved.

The first 3/9ths displays the first 20 degrees. The next 4/9ths displays the range from 0 to 60 degrees. The final 2/9ths displays the range from 60 to 90 degrees. These match tadpole plots occasionally used by some industry participants.
