Abstract

Glacial sediments have long been of significant interest, not only from an Earth history perspective, polar ice masses evolution, and their close relationship with global temperature, but also as a response to the exploration and development of oil hydrocarbons, groundwater, and, recently, CO2 capture and storage operations. The present study focused on subsurface data (well logs, core, and 3D seismic) acquired in SW Libya (Murzuq Basin), aims to unravel the architectural complexities of late Ordovician glaciogenic sediments and their potential as reservoirs. As a result of the integration of a suite of inter-related research techniques and disciplines (Seismic spectral decomposition, paleogeographic reconstruction, inorganic geochemistry, seismic stratigraphy, facies analysis, and Geomorphological comparison with modern analogs), a comprehensive facies scheme and depositional models are proposed providing a better understanding of both their spatial and stratigraphic distributions, the linkage between different environments, varying reservoir properties, and the study area sedimentological evolution.
