MORALES-GONZALEZ, Jessica; PARDO-ECHARTE, Manuel  e  RODRIGUEZ-MORAN, Osvaldo. Possible gaso-petroleum occurrence from non-seismic and non-conventional exploration methods in the Central Basin, Cuba. Bol. cienc. tierra [online]. 2020, n.47, pp.15-20.  Epub 31-Jan-2022. ISSN 0120-3630.  https://doi.org/10.15446/rbct.n47.82641.

In various geological situations, seismic data provides little information about whether a trap contains hydrocarbons. It is well documented that the generality of hydrocarbon accumulations has predominantly vertical microfiltration. The use of non-seismic and non-conventional exploration methods, integrated with geological and seismic data, enables a better evaluation of prospects and exploration risk; such is the purpose of the investigation. The general objective was to map possible new gaso-petroleum targets that support exploration in the study region. The cartography of the areas of interest would be based on the presence of the indicator anomalies: gravimetric, aeromagnetic and airborne gamma spectrometric. In addition, a 2D model of the potential fields of the Jatibonico oilfield was designed to validate the hypothesis that the magnetic maximums reduced to the pole are the cartographic expression of the continental margin carbonate uplifts. The results indicate that the anomalous complex of the Cristales oilfield is reproduced in the location of La Vigía, which manifests as a preserved occurrence, according to the results of recognition by the Redox Complex .
