This book assesses the use of various non-seismic and non-conventional oil and gas exploration methods in Cuba. In addition to discussing the benefits of these methods, the book demonstrates how they can be combined with geological data and conventional methods, leading to a better evaluation of prospects and exploration risks.

This book assesses the use of various non-seismic and non-conventional oil and gas exploration methods in Cuba. In addition to discussing the benefits of these methods, the book demonstrates how they can be combined with geological data and conventional methods, leading to a better evaluation of prospects and exploration risks. The authors describe how potential new gaso-petroleum sites in the Pina-Ceballos and Sancti Spiritus regions can be effectively mapped. The geophysical-geochemical exploration techniques combined in the Redox Complex method are used to identify and evaluate these sites. Areas of interest are mapped based on the presence of a combination of indicator anomalies, mainly derived using gravimetric, aeromagnetic and airborne gamma spectrometry. The geochemical study concentrates on two petroleum-rich regions, one in northern and one in southern Cuba. The scope also includes the seas to the south of Cuba, which are studied with non-seismic exploration tools such as the Digital Elevation Model, which employs morphotectonic regionalization.

The so-called "Non-conventional geophysical-geochemical exploration methods" are used, in the particular case of oil and gas exploration, for the detection and mapping of active microseepage of light hydrocarbons with a vertical nature on the gas-oil accumulations.The non-seismic exploration methods used in Cuba are: Remote Sensing, Gravimetry, Aeromagnetometry, Airborne Gamma Spectrometry (AGS) and Morphometry (non-conventional, from the Digital Elevation Model 90x90m). The AGS also classifies, as a non-conventional geophysical-geochemical method, together with the Redox Complex.Besides, it is of interest to know the geological-structural framework where these microseepage occur. That is why the benefits of using these methods (excluding Redox Complex), prior to their integration with geological and seismic data, translate into a first approximation, valid for an initial understanding of geology and mapping of favourable areas of possible gas-oil interest.Finally, from the implementation of these methods (including Redox Complex), perspective sectors for oil and gas are obtained, once the integration with geology and seismic has been carried out.The book presents a brief theoretical account of the methods used and, as practical results, a set of perspective sectors of possible interest for exploration in Cuba.As a complementary result, the book also offer an evaluation of the areas that meet the petroleum-geologist premises for the presence of large accumulations of high quality oil in Cuba.
