Enthought Pore Pressure Prediction

The Enthought Pore Pressure Prediction application lets you calibrate your prediction model with known well-log data. You can then apply that model to predict pressures based on 2-D and 3-D seismic data, using prediction algorithms such as Eaton, Bowers, or Eberhart-Phillips/Han/Zoback.

Automation

The application automates many of the steps that are typically involved in pressure analysis. The application can:

• Create overburden from hand-edited density.
• Detect sand/shale lithology.
• Fit a normal compaction trend (NCT) curve to porosity data.
• Create pseudo-wells.

1-D Calibration

The application automatically calculates pressure curves that you can then refine. You can:

• Change calculation parameters.
• Modify the curves on which the calculation is based, such as NCT or sand/shale lines.
• Quickly perform as many refinement iterations as you need to arrive at a satisfactory result.

2-D and 3-D Prediction

The application supports applying the prediction model from the 1-D data to 2-D and 3-D data. You can:

• Import seismic data in SEGY or ASCII format.
• Smooth or correct seismic velocities.
• View and adjust NCT at arbitrary locations.
• Fit NCT curves automatically, without well control.
• View a cross section along an inline, a crossline, or an arbitrary slice through a cube, for pressure, fracture gradient, or velocity.
• Export fracture gradients, pressures, or raw data.
