TerraStation Version 7.430 - 14 December, 2016

IMAGELog - the header for a sonic waveform track can now be vertically oriented.

IMAGELog - a crash condition when doing a left click drag operation on a facies bed boundary in the facies track has been fixed.

IMAGELog - depth label size can now be controlled by the user in the 3D borehole visualizer option.

IMAGELog - a problem with color distribution when using a small number of colors in the color map for a color coded track has been corrected.

General - user control for the screen display logo has been added to the Edit - Preferences - Plotting section of the main menu window.

TS V7.429 - 30 November,2016

TerraStation Version 7.429 - 30 November, 2016

Data Loading - DLIS image mnemonics longer than sixteen characters are now possible.

IMAGELog - Sonic Waveform - a system for customizing the track title for sonic waveform tracks has been added. If the track title is left blank, then the track title will use the Slot Name of the waveform file. If that is not set, then it will use the slot name from the tsswffil.v70 file. If that is missing then it will use the "SWF x" where x is the sonic waveform file number as the track title.

General - users may specify a custom screen logo to appear on the upper right of various petrophysical displays such as histograms, ternary diagrams, crossplots, and bar graphs. This requires an addition to control file in the form of:

      (global (define screen_logo_file "xxxxx.bmp/jpg/tif"));

TS V7.428 - 2 November, 2016

TerraStation Version 7.428 - 02 November, 2016

IMAGELog - Pressure Modeling - the level of interactivity has been changed to offer the user more control over redraws in the Pressure Model track. Redraws may be "Off", "Full, All Curves", or "Stress Models Only".

Petrophysics - Equus - a problem with file handling when copying an equation has been fixed. This also applies to the Map Equus feature in the map module.

TS V7.427 - 26 October, 2016

TerraStation Version 7.427 - 26 October, 2016

Borehole Imaging - a pick analysis option has been added to save normal and shear stresses on critically stressed fractures. Normal stresses are saved in the VALUE column and shear stresses are saved in the MEAN column of the PCK file. These are the effective stresses in PSI.

Production Data - changed the decline curve analysis to use harmonic, exponential and hyperbolic fits. Also some display changes to show ratios on a separate axis.

TS V7.426 - 12 October, 2016

TerraStation Version 7.426 - 12 October, 2016

Sonic Waveform - when calculating frequency dispersion in combined anisotropy mode, both fast and slow dispersions are now calculated.

Petrophysics - Fast Formation Evaluation can now includes logic to handle the presence of coal and salt. If coal or salt is present then output porosities are set to zero and output Sw's to 1.0.

Petrophysics - the user interface for Fast Formation Evalution has been updated to the tree menu structure.

IMAGELog - Curve Listing track. The angle of text display for numeric curve tracks can now be controlled by the user.

TerraStation Version 7.424 - 14 September, 2016

Sonic Waveform - negative semblance arrival window offsets are now permited.

Data Loading - a problem with data increment units (introduced in V 7.422) has been corrected.

IMAGELog - Biostratigraphy track - a new "abundances (text)" display is now available. This shows abundances as a single text character. A colored background to the characters can be done by using the new QUALIFIER entry in the data file.

IMAGELog - a "reverse hourglass" option has been added to color coded curve tracks.

Dip Analysis - a problem with color coding on walkout plots when using a stratigraphy file has been fixed.

Petrophysics - three new methods for multi-well normalizing have been added.

Borehole Imaging - Tadpole Track - tadpoles can now be filled gradually based on the quality setting of the pick.

General - zoom response times have been improved.
