We present new features of VSL cosmologies and show that they face problems explaining the cosmological isotropy problem. We also find that if c falls fast enough to solve the flatness and horizon problems then the quantum wavelengths of massive particle states and the radii of primordial black holes can grow to exceed the scale of the particle horizon. This may provide VSL cosmologies with a self-reproduction property. The constraint of entropy increase is also discussed. The new problems described in the this letter provide a set of bench tests for more sophisticated VSL theories to pass.

The approach is unusual in two respects: firstly, the uncertainty is quantified by using traditional stochastic methods combined with an analysis of the representativity of wells, secondly, the oil-in-place is calculated within a sedimentological framework, that is, by genetic sedimentary units. The former step is performed by a method known as the "Bootstrap" technique. The geostatistical modelling is constrained by detailed seismic, well and pressure data. The statistical and geostatistical methods are presented, along with a discussion of the broader implications for the quantification of uncertainty. The second part of the paper details the application of the technique to an appraisal stage field. Introduction The appraisal phase is a crucial time in the life of a field, particularly as fields are increasingly being exploited on the margins...

Heterogeneity is mainly controlled by the distribution of sandstones embedded in laminated facies. Channels and lobes account for most of the production. Their frequencies and geometries are critical factors that affect reservoir connectivity, hence oil recovery. The combined used of flexible stochastic techniques allows generating realistic 3D models of this complex architecture. The modelling strategy is multi-steps, with first a geologically constrained generation of facies distributions, and second, simulations of permeability variations within the previously permeability variations within the previously generated facies distributions. Introduction W-field, discovered in the early sixties. is located offshore of a large sedimentary basin whose origin is linked to the opening of the Atlantic ocean. After a fe...
