Abstract
La Cuenca de San Pedro (CSP) se define como una depresión batimétrica con tendencia E-O y una extensión aproximada de 6000 km2, situada en el margen sureste de la isla de La Española (República Dominicana y Haití). Estructuralmente, el SPB está ubicada en la parte trasera del Cinturón Deformado de los Muertos (CDM). Considerada tradicionalmente como una cuenca de edad Mioceno medio, cuyo relleno ha sido depositado en el espacio de configuración generado por la progresiva deformación del CDM. El área de estudio pertenece al límite norte entre las Placas Norteamericana y Caribe, habiendo registrado la compleja interacción entre ambas. Aun-que la CSP se encuentra próxima a un sistema petrolero confirmado (los descubrimientos de Ma-leno e Higuerito en la región de Azua recuperaron 50,000 brls de petróleo), podría considerarse como poco explorada y los diferentes intentos de correlaciones estructurales y estratigráficas con la región de San Cristóbal (tradicionalmente considerada como la extensión en tierra de la CSP) y la cuenca de Azua han puesto de manifiesto importantes discrepancias. En consecuencia, tanto la evolución de la CSP como su potencial de hidrocarburos siguen sin estar claramente definidos...
The San Pedro Basin (SPB) consists of an E-W bathymetric depression with an extension of 6000 km2, located in the south-eastern margin of Hispaniola Island (Dominican Republic and Haiti). Structurally, the SPB is situated at the rear zone of the Muertos Thrust Belt (MTB). The basin has been dated as middle Miocene in the bibliography, with the infill deposited in the configuration space generated by the progressive deformation of the MTB. The study area belongs to the north-ern limit of the Caribbean Plate, having recorded the complex interaction with the North Ameri-can Plate. Although the SPB is located close to a confirmed petroleum system (the discoveries of Maleno and Higuerito in the Azua region recovered 50,000 brls of oil), it remains almost unex-plored and the different attempts of onshore-offshore structural and stratigraphic correlations with the nearby San Cristóbal (traditionally considered as the onshore extension of SPB) and Azua Basins have shown strong discrepancies. Therefore, the SPB evolution and its hydrocarbon po-tential remains unclear...
