Oil and Gas Exploration in Cuba offers a comprehensive analysis of geological and structural mapping in various regions of Cuba, including the western, central, and central-eastern areas. The book presents the results of studies supported by potential fields and airborne gamma spectrometry data. It provides a detailed overview of the structural-tectonic regionalization relevant to hydrocarbon exploration, with a particular focus on identifying new oil and gas targets in specific land blocks. Additionally, case studies are presented for certain locations where innovative geophysical-geochemical exploration techniques have been successfully applied. The use of gravity-magnetometric data for mapping the metamorphic massif Isla de la Juventud is also addressed, with results indicating the discovery of granitic bodies formed through complex geological processes.
