Description
Ecopetrol - ICP participó en la última campaña oceanográfca de investigación y reconocimiento del Integrated Ocean Drilling Program (IODP) cuya misión era reconocer un área en el Océano Pacífco (Papette (Tahiti) - Honolulu (Hawaii)) donde se harán ocho perforaciones estratigráfcas. El objetivo es hacer estudios referentes a cambio climático, paleoproduc-tividad, bioestratigrafía, calibraciones astronómicas de eventos geológicos, perfles de temperatura, evolución geológica y modelos de circulación y sedimentación. El reconocimiento del área se basa en el uso de unas herramientas, que permiten la visualización de las características del suelo marino a perforar. Estas herramientas son la sísmica, magnetometría, ecosonda, batimetría multi-beam, piston coring y el multi system track, entre otras.
Ecopetrol - ICP realizó una prueba en la bahía de Santa Marta, aplicando las metodologías aprendidas en la campaña del IODP para recuperar muestras del fondo marino. Esta prueba resultó ser un éxito, se obtuvieron corazones a profundidades que oscilan entre 20 y 400 m. Con estas muestras se busca realizar estudios bioestratigráfcos basados en la distribución de foraminíferos recientes, para generar un modelo que permita predecir paleoambientes y paleobatimetrías y por ende, aportar al entendimiento de la geometría de los reservorios en cuencas marinas.

Ecopetrol ICP took part in the last Research & Reconnaissance Oceanographic Cruise of the Integrated Ocean Drilling Program (IODP), its mission was to recognize an area in the Pacifc Ocean (Papette (Tahiti) - Honolulu (Hawaii)) where they will drill eight stratigraphic wells. The objective is to develop studies about climate change, palaeoproductivity, biostratigraphy, astronomic calibrations of geological events, temperature profles, geological evolution and circulation and sedimentation patterns. The reconnaissance of the area is based in the use of some tools, which allow the visualization of the sea foor characteristics to drill. Those tools are the seismic, magnetometry, ecosounder, multi-beam bathymetry, piston coring and the Multi System Track, among others. Ecopetrol ICP made a test in the Santa Marta bay applying the learned methods in the IODP cruise to extract sea foor samples. This test turned out successful, we obtained depth core samples between 20 and 400 meters. With those samples we want to made biostratigraphy studies based in recent foraminifera distribution, to generate a model that allows to predict palaeoenvironments and palaeodepths and in this way contribute to the understanding of reservoir geometry in marine basins. Key words: IODP, Exploration, Offshore Basin, Ecopetrol - ICP, Foraminifera.
