description |
Through the integration of seismic and well data, it is possible to construct a model of the subsurface, which is analyzed to identify sandstones bodies, their stratigraphic location and possible structural deformation. This integrated interpretation is used to analyze elements of the petroleum system, such as the trap and the reservoir. The area of study is located on a basement high which, together with the regional dip of the basin have favored hydrocarbon migration. Coherence/variance, root-mean square (RMS), and spectral decomposition seismic attributes helped to define the structural and stratigraphic features, as well as the distribution of sandstones. Two structural trends are identified, the first one with a predominantly N-S direction that controls the configuration of the geobodies identified. The second with a NE-SW direction that is parallel to the direction of the deformation front of the orogen. From the Paleozoic top to the Barcos-Cuervos top, two sedimentary cycles were distinguished in the time slice: a) Gachetá Basal Fm. and Gachetá Fm. b) Guadalupe Fm. and Barcos-Cuervo Fm. The Gachetá Formation presents an approximate thickness of 300 ft., equivalent to 50 ms (TWT). The formation was divided into two intervals separated by a boundary established by an analysis developed in a previous study of stratigraphic sequences made by Cepsa. This division was made aiming to perform the supervised facies classification inside each interval. The results evidence the existence of two sedimentary cycle within the area. The first (a) has an inner shelf dominance, and the second (b) is dominated by coastal plain environments. The wells corresponding to facies 1 have the greatest sandstones content. The sandstones of the Gachetá Formation are an exploratory target and it is recommended to study further these sandstones using quantitative seismic interpretation methodology |

Con esta interpretación integrada se están analizando dos elementos del sistema petrolífero: trampa y roca almacén. El área de estudio se encuentra en un alto de basamento, y junto con el buzamiento regional de la cuenca han favorecido la migración de hidrocarburo Los atributos sísmicos de coherencia/variancia, root-mean square (RMS) y descomposición espectral permitieron definir el control estructural y estratigráfico del área y la dependencia en este sector de la distribución de las arenas. Se identifican dos trenes estructurales, el primero y preponderante con dirección N-S controla la configuración de los geocuerpos identificados; el segundo de dirección NE-SW, paralelo a la dirección del frente de deformación del orógeno. En la zona correspondiente entre el tope del Paleozoico y el Tope de Barcos-Cuervos, se distinguieron dos a ciclos sedimentarios con asociaciones propias de un mismo ambiente visualizado en los times slice: a) Fm. Gachetá Basal y Fm. Gacheta y b) Fm. Guadalupe y Fm. Barcos-Cuervo La Formación Gachetá en el área presenta un espesor aproximado de 300 pies correspondiente a 50 ms (TWT). La Formación fue dividida en dos intervalos separados por un límite de secuencia según el análisis realizado por Cepsa. Los resultados soportan la existencia de dos ciclos sedimentarios. El primero (a) corresponde a un dominio de plataforma interna y el segundo (b) a una planicie costera. Los pozos con las facies denominadas facies 1 son las que tienen mejor contenido de arenas. Las areniscas de la Formación Gachetá constituyen en un objetivo exploratorio y se recomienda su estudio con la aplicación detallada de la metodología de interpretación cuantitativa conocidaGeocientíficoPregrado119 hojasapplication/pdfengUniversidad de los AndesGeocienciasFacultad de CienciasDepartamento de Geocienciasinstname:Universidad de los Andesreponame:Repositorio Institucional SénecaGeophysical and geological interpretation of cretaceous rocks (Gachetá and basal Gachetá formations) in the south Casanare area, Llanos basinTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPPaleogeofísicaGeología del petróleoEstratigrafíaGachetá (Región Colombia)GeocienciasPublicationhttps://scholar.google.es/citations?user=3QCeJHwAAAAJvirtual::15820-10000-0002-1600-6445virtual::15820-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000054450virtual::15820-14dafb0f7-569a-4cb5-bd0a-3a5494a93309virtual::15820-14dafb0f7-569a-4cb5-bd0a-3a5494a93309virtual::15820-1ORIGINALu806934.pdfapplication/pdf13292064https://repositorio.uniandes.edu.co/bitstreams/9521825b-699d-4b59-bd2b-324794fa3555/downloadcb8cef87aa21577e39572111366b93c3MD51THUMBNAILu806934.pdf.jpgu806934.pdf.jpgIM Thumbnailimage/jpeg8339https://repositorio.uniandes.edu.co/bitstreams/a20006b5-9598-410c-b7c1-f1a2c7daed23/downloadaee66b6103ca0d95e5af3af6e3b15e63MD55TEXTu806934.pdf.txtu806934.pdf.txtExtracted texttext/plain144987https://repositorio.uniandes.edu.co/bitstreams/0f4080b0-3e9b-4c60-9fbe-4351f8d3b4d2/download7c9f0757d13ff36768f7884d6553b0ecMD541992/39625oai:repositorio.uniandes.edu.co:1992/396252024-03-13 15:33:44.493http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
