Abstract

Summary

This submission documents the geochemical characteristics of oil samples recovered from the Athena Oilfield in the Jura Basin of the U.K. sector of the Central North Sea. The oil shows geochemical characteristics which are atypical of other North Sea oils and which suggests expluslion from a carbonate-rich facies of the Kimmeridge Clay Formation which, to date has gone undocumented in the U.K. sector of the North Sea and has implications for exploration on the margins of these mature basins. The presence of such carbonate source rocks and associated, labile, Type II-S kerogens at the margins of the main Upper Jurassic basins may allow the mapping of effective source kitchens to extend further afield than are currently anticipated - allowing the charging of mapped prospects that were once thought to lay too far from effective source rocks to be viable.
