Preliminary cyclostratigraphy on planktonic foraminifera from IODP-Hole U1406A

Alessio Fabbrini, Luca Foresi, Isabelle Lecomte & Fabrizio Lirer
Cyclostratigraphy reconstructs astronomical-periodic signals in quantitative data from climate-sensitive proxies, as microfossils, carbonate content, isotopic data or any physical properties measurable at sufficient resolution. The astronomical cycles strongly influence the climate changes at a long time scale. The deep link between climate, sedimentation and orbitally forced insolation can be detected at a smaller scale and it allows the tuning of sedimentary sequences using foraminifera. This study investigated the interval 23.40-21.17 Ma within IODP Site U1406...

Interwell meter-scale depositional heterogeneity is a key geologic factor behind un-even fluid advance in carbonate reservoirs undergoing waterflooding and enhanced oil recovery developments. Subsurface data (seismic and well data) are limited in both resolution and data density to resolve this level of heterogeneity. Outcrop analogues are commonly utilized to fill this data gap on...

Modelling 2 Phase Flow in Heterogeneous and Anisotropic Rocks using AFRMs

Paul William, John Glover, Piroska Lorinczi & Saddam Sinan
University of Leeds, United Kingdom

Geological modelling and flow simulation in the subsurface in heterogeneous and anisotropic media is increasingly common. Unfortunately, conventional modelling using statistical techniques, up-scaling and interpolation to populate the inter-well volume of sparse datasets have a low resolution (> 50 m). Consequently they have difficulty modelling heterogeneous and anisotropic reservoirs. This paper focusses on modelling and simulation of heterogeneous and anisotropic reservoirs using a fractal approach (Advanced Fractal Reservoir...
