Overview

The Saturation-Height Modeling module provides core-to-log integration via the following workflow:

  • Template loading of special core data.
  • Graphical review and edit for QC.
  • Transform or normalize pressure data.
  • Model capillary pressure data shapes.
  • Apply models within log domain.
  • Solve for free fluid level by hydraulic zone.
First step: The equation is applied to the samples in order to derive the parameters.
Second step: The matrix of fitted parameters versus formation properties, illustrating best-fitting equations.
Third step: A combined single function applied across all data in a single rock type.
Saturation height model results: Comparison of the core model and optimized model, using solver.
Applications

Model application

Capillary pressure models can be easily saved, and direct graphical and quantitative comparisons made against log derived results. Models can be optimized to fully reconcile log and core data using an integrated solver.

Benefits

Model design

There are four common functions available within the SHM module: Brooks-Corey, Lambda, Thomeer, and Leverett-J function. Each functional solution has three coefficients. The coefficient values can be automatically correlated against formation properties—such as φ, sqrt(K/φ), and K—using different fit criteria (linear, logarithmic, exponential, power, and average). The coefficients can be set to be functions of the formation parameters or to be constants, and instant comparison against “standard” models can be made for rock typing.
