TS V7.228 22 July, 2011

TS V7.228 21 July, 2011

DLIS Loading - file assignment for sonic waveform data has been improved for better consistency of data organization.

Pick Data Options - a new option has been added to the computations available for linear features.  The new option is the "Linear Feature Direction" option.  It represents the azimuthal "direction" of the linear feature, in degrees constrained from 0 to 180.  This is equivalent to the old "Linear Feature True Azimuth" option.  It is the eastern half compass direction, looking down from above, that the feature points towards.

The True Azimuth option now shows an angle from 0-360, which is the compass direction, looking down from above, from the borehole center to the center point of the feature.  This is the same as the breakout option of the same name. It can be used to indicate direction for features which do not extend through the borehole.

For plotting purposes on dip displays, under both these options a dip of 85 degrees is assigned.

Note: previous IMAGELog templates which stored one of these options may not work as expected since the numbering of the options has changed.

Petrophysics - the decimal precision in Multiple Linear Regression has been improved for small numbers.

Petrophysics - the Archie equation constants A, M, and N are now included in multiwell crossplots.

TS V7.226 7 July, 2011

TS V7.226 6 July, 2011

General - the startup sequence for TerraStation has been changed to eliminate the "splash screen".  This is due to security problems under some Windows firewall settings.  A few users had changed the Target in the startup icon to work around this problem.  Beginning with this release, if you had implemented the work-around, you will need to return it to the original system.  We apologize for the inconvenience.

Sonic Waveform - Semblance - the semblance algorithm now allows a larger arrival window to be specified.

Sonic Waveform - Data Control - compressional, shear and density data (DTC, DTS, RHO) can be used to compute rock properties.  PR, YME, KMOD, UMOD, VPVS are created as output curves.  This computation takes place over the current depth interval.

Petrophysics - Crossplot - a key has been added to the color-contour map crossplot display.

Plot Output - PDF - we have improved font geometry to allow for better text justification in center and right justified text strings.
