- [German] So, the motivation. We are going to be, I'm going to be showing an example from the Almond formation, which is a Cretaceous marine and non-marine formation in the southern field, which is located in the southwest corner of the Wyoming state in the US. So a couple of factors make the Almond formation behave more similarly to a conventional reservoir. So first, the present-day structure, which is shown in these control lines, in the northern part of the field, is quite similar to the one in the Eocene time, when this hydrocarbon migrated into the reservoir. So, the dark blue represents the deeper structure, and the lighter color represents the shallower structure. The second important thing is that the trap mold has a strong stratigraphic component, with a overlying Lewis formation, kind of providing a regional seal. Also, you have lagoonal and marine shales providing lateral seals. So these are the main reservoirs for the upper Almond, which are shore face pass You have pretty good lateral and on top seal. All these reservoirs, I also charge with seeing, I'll adjust with other carbon be the medium interformational source rope, we chartered a course. We charter throughout, we can be found throughout the sea. So, these facts encouraged us to derive, and implement drainage saturation-height models for kind of better understanding the correlation between saturation distribution and reservoir quality. Also, a last highlighting mismatch is between saturation models and resistivity derive water saturation models. Given that some reservoirs, like in this case, the ones labeled with number one and number four, display high water saturation that the other bars, like the one show less number two and number three. This is a really good opportunity for testing inhibition and saturation models. You will see later on how we model primary drainage and primary inhibition model. Anything more complicated than that, like secondary inhibition and secondary drainage, is not included in this work. So, in other words, anything more complex than primary and secondary... For anything more complicated than primary inhibition and primary drainage is not included here.
