The application of outcrop analogues in geological modelling: a review, present status and future outlook

Abstract: Abstract Analogues, especially outcrop analogues, have played a central role in improving understanding of subsurface reservoir architectures. Analogues provide important information on geobody size, geometry and potential connectivity. The historical application of outcrop analogues for understanding geobody distributions in reservoirs is reviewed, from the pioneering work of the 1960s to the high-tech virtual outcrop methodologies of today. Four key types of analogue data are identified: hard data, which describe the dimensions and geometry of the geobody; soft data, which describe the conceptual relationships between different geobody types; training images, which record the dimensions, proportions and spatial relationship; and analogue production data, which are taken from direct subsurface production analogues. The use of these different data types at different stages of the geomodelling workflow is discussed and the potential sources of error considered. Finally, a review of geobody and analogue studies in different clastic environments is discussed with reference to selected previous work and the range of papers in the current volume.

Nanocomposite materials (LAW392)

Abstract: The present invention relates to a latex comprising water and a layered material intercalated with a polymer. The invention also relates to a nanocomposite material comprising a layered material intercalated with a polymer. The latex can be produced by forming a dispersion of layered material in water, adding surfactant, polymerizable monomer or monomers, and a polymerization initiator to the mixture and then polymerizing the monomer to form a latex. The latex can also be formed from preformed polymers. Composite materials formed from latexes produced by either method have improved mechanical properties and reduced air permeability.

Domain-growth kinetics for the Q-state Potts model in two and three dimensions

Abstract: We present new simulations of the domain-growth kinetics for the Q-state Potts model in two and three dimensions. The time dependence of the average grain radius R\ifmmode\bar\else\textasciimacron\fi{} can be described by R\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\simeq}${\mathrm{Bt}}^{n}$, where B is a temperature-dependent constant. In two dimensions, we find n=0.49\ifmmode\pm\else\textpm\fi{}0.02 for a range of Q values from 2 to 48. This value of n is obtained from very long simulations on lattices up to size ${1000}^{2}$ and is in contrast to our earlier estimates for n which were less than (1/2 (n\ensuremath{\simeq}0.41\ifmmode\pm\else\textpm\fi{}0.01) for large Q. In three dimensions on lattices of size ${100}^{3}$, we find that n=0.48\ifmmode\pm\else\textpm\fi{}0.04 if early-time data are excluded from the fit to the kinetic data but smaller if the entire data set is used. The grain-size distribution for several values of Q in both two and three dimensions is also determined and compared with our results for grain growth in real polycrystalline materials.
