PORE PRESSURE PREDICTION.
Pore pressure prediction uses sonic data to estimate pore pressure in the mudrocks. At the most basic level, it uses the following approach: 1) it uses overburden and hydrostatic gradients to estimate vertical effective stress at any depth 2) it predicts acoustic velocity for the normal compaction trend (hydrostatic effective stress) in the mudrock 3) it predicts pore pressure based on the deviation of the sonic data from the normal compaction trend. The app has interactive module for workign with the density logs as well as picking mudrock intervals.

LANDSLIDE AGE FROM BSR 2D.
This interactive application calculates the age of a submarine landslide using bottom simulating reflection (BSR) underlying a slide-impacted seafloor in the seismic data. This application loads your seismic image in *jpg format; it allows to pick horizons, assign variable geothermal gradient, estimate steady-state BSR depths, and acquire landslide age along the selected line. The application is based on Portnov et al.(2022) paper, which provides numerical and analytical solutions for conductive heat flow transfer upon the change of the upper boundary condition triggered by a landslide. Landslide Age From BSR is based on the original analytical solution using temperatures to calculate fractional dissipation.

LANDSLIDE AGE FROM BSR 1D.
This application calculates the age of a submarine landslide using bottom simulating reflection (BSR) underlying a slide-impacted seafloor in the seismic data. The application is based on Portnov et al.(2022) paper, which provides numerical and analytical solutions for conductive heat flow transfer upon the change of the upper boundary condition triggered by a landslide. Landslide Age From BSR is based on the original analytical solution using temperatures to calculate fractional dissipation. It works for a selected 1D location only.

TEMPERATURE FROM BSR.
This application calculates geothermal gradient based on the depth of a seismic BSR, or predicts the depth of a BSR (base of gas hydrate stability zone) if the geothermal gradient and bottom water temperature are known. The application uses 100% methane phase boundary curve obtained using CSMHYD application (http://hydrates.mines.edu/CHR/Software.html), 3.5 % NaCl salinity and 1024 g/cm3 water density for pressure-depth conversions.

TWO WAY TIME to DEPTH.
The application is a fast way to predict depth in meters from the two-way-travel time. It offers two options: use default velocity model and use custom velocity model.
