| Dynamic capillary model - a new tool for petrophysical modeling | |
| The dynamic capillary model is based on a fundamentally new approach to processing and approximating capillary pressure curves. This model was developed as an alternative to approximating capillary models, which have now become, with the involvement of specialized software products, a standard in petrophysical practice. The model was tested on a series of capillarymetric studies of core samples of terrigenous strata in Western Siberia and showed high accuracy of data reproduction, including for complex S-shaped capillary pressure curves of low-permeability samples. The dynamic capillary model can serve as an alternative tool for petrophysical modeling in cases of unsatisfactory results of using classical capillary models or unavailability of specialized software. Keywords: dynamic capillary model, capillarymetric studie, capillary pressure curves, petrophysical modeling. |
