Here we demonstrate how zeta potentials that agree with measured values can be calculated by: (1) integrating the net average charge in surface-parallel layers from the midpoint of the fluid layer (where the electrostatic potential is zero) to and then into two solid caps, (2) determining the position of slipping plane with separate Couette flow models, and (3) calculating the charge distribution and electrostatic potential under static conditions. The solids we model are charge neutral surfaces composed of atoms with zero charge or charge balanced monovalent or divalent ions. The zeta potentials calculated are within a few millivolts of measured values, and the measured values fall within the simulation error bars. Insights provided by the improved MD simulations into the complex phenomena that affect surface charge and zeta potential are discussed.

The new basin models not only reduce exploration risk on a basinwide scale but also prioritize blocks of interest on subbasin or smaller scales. However, the models must be robust and easy to use to be effective in a competitive oilexploration environment. In many cases, faults are petroleum migration conduits, especially at depths less than a few kilometers. This is clearly indicated by observations in extensional basins with high deposition rates, such as the Gulf of Mexico and the Niger Delta. Model stability largely involves the handling of faults in 3-D. Most gridding schemes either superimpose a regular grid on complex depositional patterns and structures or capture some or all of the geologic complexity with disjointed grids or grids that are highly deformed in fault zones. A practical alternative to these...
