-The latest version of 3DUTAPWeLS, version 4.28, was released on May 17th 2018.
IMPORTANT: Pre-4.00 projects are no longer compatible with UTAPWeLS versions 4.25 and above. Pre-4.00 projects may be updated using v4.00 through v4.24 with v4.24 recommended.
*Fast Sonic Logging
-The fast sonic logging simulator works with vertical wells and horizontal layers.
-The module has received a general update making plots faster, and easier to navigate.
-Calculation and plot of first arrivals has been reinstated.
-Advanced settings, for wave form simulators are now available for use.
*Updated rock components properties according to "Advanced Interpretation of Wireline Logs (SLB)"
-Density, Th (ppm), Ur (ppm), and K (%) properties have been updated.
*Various Smaller Bugs and Features
-The display unit system is consistent across project (not just the well).
