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 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.

This book studies the “Redox Complex”, a complex of unconventional geophysical-geochemical exploration techniques used for the indirect detection, characterization and evaluation of various metal targets, while also illustrating selected applications of unconventional geophysical-geochemical methods for oil exploration in Cuba. This complex is successfully applied in various fields: oil & gas and metal ores exploration; studies of oil and metal contaminants in soils; and the search for metallic archaeological burials. The use of these techniques is intended to complement the conventional prospecting complex by reducing areas and/or facilitating the selection of the most favorable targets, improving the economical-geological effectiveness of investigations in the process. Further, the Redox Complex can be implemented without physical or chemical damage to the environment. The book’s primary goals are to: 1) outline the general features characterizing the processes of metal mobilization, transport and accumulation on surficial media; 2) outline the methodology, data interpretation and mathematical apparatus that support quantitative estimates of the Redox Complex; and 3) design a database and applications system (the Redox System) to address storage processes, reports, graphics and the corresponding interpretations of the Redox Complex in a quick and reliable way. To do so, it examines the regions of Havana-Matanzas (Varadero Oil Field, Cantel Oil Field and Madruga Prospect) and Ciego de Ávila (Pina Oil Field, Cristales Oil Field, Jatibonico Oil Field, Jatibonico Oeste Prospect and Cacahual Prospect). The methods covered include, in some cases, airborne gamma spectrometry (K/eTh ratio) beside ORP and, in others, the Redox Complex with reduced or standard attributes. In all cases, the anomalous complex of interest corresponds to the correlation of the minimum K/eTh ratio with minimum ORP and, in the case of the Redox Complex, Magnetic Susceptibility highs with ORP lows, Spectral Reflectance lows and maximum Content of Chemical Elements (V, Ni, Pb, Zn, Fe).
