We develop high-resolution models, derived from suitable outcrop analogues, and use them as a 'laboratory' to simulate and understand multiphase flow in heterogeneous reservoirs and hence solve problems of interest to both reservoir geoscientists and engineers.
Outcrop analogues have long been used by geoscientists to improve their understanding of the subsurface, but it is only recently that engineers have recognised the value of outcrop derived models to capture key aspects of fluid flow which are lost in typical subsurface models.
As part of the NORMS group, we have developed a unique resource of skills and techniques which allows us to build high resolution 3-D models from suitable outcrop data, at length-scales ranging from a few tens of centimetres to several kilometres, and simulate multiphase flow directly on these models.
The detailed spatial relationships captured in these outcrop-based models also allow us to re-evaluate our understanding of the geological processes that control reservoir architecture, and hence address fundamental scientific issues in sedimentology and stratigraphy.
