Abstract
The need to have gas and oil reserves is imperative in the contemporary world and in the case of Cuba the situation is accentuated due to external factors. For this reason, numerous investigations are carried out in the national territory to locate favorable structures where accumulations of hydrocarbons can be found. The objective of this research has been to study the marine sediments of the Gulf of Guacanayabo (Eastern Cuba), the indications of hydrocarbons in the seabed and the establishment of the areas of greatest interest. For this study, the combined use of bathymetry and high-resolution reflection seismic was used to map anomalous structures classified as possible pockmarks and mud volcanoes, morphologies generated by natural hydrocarbon emissions in the seabed. Likewise, the relationship between gaseous emanations and the presence of gas in the sediments of the seabed and the deep and shallow structures in the region has been established. Finally, the areas with the greatest potential have been established from the integration of all the available results. This study allows to ensure the potentialities of the Gulf of Guacanayabo for subsequent studies in relation to the presence of hydrocarbons in the subsoil.
