The submarine fan/channel complex of the Eocene Ainsa System in the south-central Pyrenees, Spain is in the process of being analysed for its microfossil content. The aims of this analysis are to establish the age and palaeoenvironment of the system, and to investigate whether the different types of (channel axis, off-axis and levee/overbank) sub-environments that it contains can be discriminated using micropalaeontological criteria, thus contributing to a hydrocarbon reservoir analogue model. This paper presents some preliminary observations.

Recent Developments in Applied Biostratigraphy
In recent years the application of biostratigraphy to hydrocarbon exploration and development has become increasingly important both scientifically and economically. The demand for higher stratigraphical resolution in field development studies has resulted in the utilization of new approaches. However, in under-explored areas with little reliable primary biostratigraphical data, conventional methods using relatively coarse biozonations still have relevance. The aim of this volume is to encourage an exchange of ideas and to seed new research initiatives particularly within integrated multidisciplinary teams. The papers are divided into four main themes which cover a broad range of modern applications of biostratigraphy. The first three themes are: UK North Sea field development; outcrop analogues; and international exploration and development. The final section discusses new methodologies, such as the application of correspondence analysis and multivariate correlation of wells, and palynological processing techniques applicable to the wellsite.
