... Popular hypotheses for secondary migration of petroleum fail to explain many of the characteristics of secondary migration systems. As an alternative, I have resurrected an old hypothesis of colloidal migration, but in much more detail than hitherto. Some numerical models to test this hypothesis...

During a mineral system evaluation, the exploration team hypothesise where genetically-related clusters of mineral deposits (mineral ‘plays’) could occur if the mineral system’s essential ingredients all coincided in 4D. Ideally, the cost:value and risk:reward...

By approximating the null- iterative approximate solver instead of the inverse Hessian. space shuttles which maximally violate a given hypothesis about the inversion, this method establishes an effective approximation of the Uncertainty quanti cation strategies in FWI...

... hypothesis of continuity, while the other is based on the good assignment probabilities. Both methods aim at providing a constraint for a geomodel with a spatial continuity consistent with the geology. These two approaches have successfully been controlled and compared. Finally, the results were integrated...

... be an artifact of the inversion algorithm. To investigate this, and to have confidence, or not, in the existence of the deep body, we carry out a hypothesis analysis where we attempt to find a model that does not have a high conductivity at depth. Forward modeling and subsequent inversion confirms...

This algorithm uses the dynamic variable density mesh mode to improve the travel-time accuracy effectively, especially in the near travel-time field. The application...
