Hydrocarbon Potential and Basin Analysis of the Southern Permian Basin, North Sea: Evaluating Key Plays in the Turonian and Carboniferous

Abstract

This research provides an in-depth basin analysis and evaluates the hydrocarbon potential in the Southern Permian Basin, North Sea, Netherlands. It employs a thorough approach, including interpreting well logs, analysing petrophysical data, mapping faults and horizons, converting time to depth, and calculating reserves. The study highlights two key plays: the Turonian play (Barremian Formation) and the Carboniferous play (Rotliegend Formation). Petrophysical analysis of the Turonian Formation shows porosity values between 8.9% and 16% and net-to-gross ratios ranging from 0.6 to 1.0, indicating variable reservoir quality with a 45% geological chance of success. In contrast, the Carboniferous play, which includes Rotliegend marine sandstones, has a 45% chance of success but benefits from better porosity and permeability than the Turonian Formation. The research produced time and depth structure maps, clarifying trap mechanisms and identifying potential leads. With its promising results, the Southern Permian Basin presents a significant opportunity for future exploration and development. However, the study notes several limitations, such as issues with power stability, the need for more 3D seismic data and missing logs like neutron and density for some wells. Addressing these issues by improving data collection and operational conditions is crucial, as it could enhance exploration accuracy and increase the chances of success in the Southern Permian Basin. It also highlights the potential for further research in this area.
