Abstract: A regional review by Total E & P on the Dinantian (Lower Carboniferous) carbonate play in the Southern North Sea and Onshore UK. This report was prepared for the UK Department of business Enterprise and Regulatory Reform (DBERR) to promote exploration of this play. It outlines the technical work undertaken by Total E & P on this play since 2002, when a regional cross-border (UK, Netherlands, Belgium and Germany) hydrocarbon prospectivity overview was completed by Total.   Description:Total E & P produced this report for UK DBERR in order to promote exploration in the Dinantian Carbonate play in the Southern North Sea and Onshore UK.  In 2002 a regional cross-border hydrocarbon prospectivity overview covering parts of the UK, Netherlands, Belgium and Germany by Total E & P highlighted the possibility of a poorly explored hydrocarbon play in the Dinantian (Lower Carboniferous). The main conclusion of that regional overview was that the Dinantian carbonate play is most favourably developed along the northern flank of the London-Brabant Massif. The purpose of this report is to summarise the technical work undertaken by Total E & P on this play since the original overview of 2002. This report includes: tectonic evolution, Carboniferous stratigraphy, reservoir development and analysis of source rocks and hydrocarbon charge.  This report is released under the NSTA User agreement.
