Saudi Arabian Permo-Triassic biostratigraphy, micropalaeontology and palaeoenvironment
Published:January 01, 2005
The Khuff Formation of Saudi Arabia consists of a succession of shallow marine carbonates, mudstones and evaporites. It is exposed along the basement-flanking outcrop belt of central Saudi Arabia, and also forms important hydrocarbon reservoirs at depth in the east. Micropalaeontological evidence suggests that the Khuff Formation in Saudi Arabia is of latest Permian to early Triassic age. Of the four members, the Permo-Triassic boundary is located at, or slightly above, the boundary between the uppermost Midhnab and Khartam Members in the outcrop belt and within the lower part of the Khuff B carbonate reservoir in the subsurface.

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.
