Caracterización geoquímica del petróleo de los reservorios de la Fm Napo del Cretácico (Ecuador) y su relación con las lutitas intercaladas como roca generadora de hidrocarburos
(2009)The Napo Formation from the Cretaceous age is located in the Oriente basin in Ecuador and is composed of limestones, shales, and sandstones, the «U» and «T sandstones», which are the most important reservoirs in the ... -
Circulación de fluidos en fracturas en el miembro superior de la Fm. Armàncies (Eoceno, Pirineo oriental)
(Sociedad Geológica de España, 2005)The presence of oil shows associated with fractures provides a significant opportunity to unravel the type, origin and evolution of fluids involved in fractures cementation and their relationship to oil migration. Two stages ... -
Control diagenètico sobre la porosidad y permeabilidad en areniscas-almacén cretácicas (área Salam, Western Desert, Egipto)
(Sociedad Geológica de España, 1996)Pelrographic analysis of core samples of reservoir sandstones from the Sa/am Field show that porosity and permeability are strongly influenced by diagenesis. The studied sandstones can be subdivided into two populations ... -
Controles composicionales, diagenéticos y de microfábrica sobre las características de la roca madre jurásica del petróleo del Campo de Salam (Western Desert, Egipto)
(Sociedad Geológica de España, 1996)Petrographic, mineralógica! (XRD), bulk geochemical (TEM, SEM and BSE) andpetrophysical analysis of selected shales, siltstones, coaly shales and coals from Jurassic Khatatba Fm. and Cretaceous Alam El Bueib (AEB) Fm. in ... -
Diagénesis y estratigrafía secuencial de la arenisca «U» de la Fm Napo del Oriente, Ecuador
(2006)The Napo Formation of Cretaceous age in the Oriente basin, Ecuador, is an important sandstone reservoir. The «U» sandstone is one oil interval within the Napo Formation. It is buried at a depth of 1500 m in the eastern part ... -
Estudio de las rocas madre del Albiense medio-superior de la región de Bir M'Cherga, Túnez: interacción de la diagénesis orgànica-inorgànica con la migración primaria de hidrocarburos
(Sociedad Geológica de España, 1994)Geochemical, mineralógicaI and petrophysic examination of the source rocks of the Middle-Upper Albien maristones and chalks from the Bir M'Cherga region (Tunisia) provide insights into factors which control the organic and ... -
Estudio textural y mineralógico de rizocreciones en los suelos terciarios de la cuenca del río Amarguillo (Toledo)
(Sociedad Geológica de España, 1997)The paleosoils of the Miocene from the Amarguillo river basin show an important development of edaphic features. These are principally argillaceous fillings of old root casts. These rizocretions show several different ... -
Heavy mineral composition and geochemistry of the Weald facies from the Maestrat Basin (Spain): Provenance implications for Late Jurassic-Early Cretaceous rifting stage
(Sociedad Geológica de España, 2005)Las areniscas en facies Weald de la Cuenca del Maestrazgo fueron depositadas durante la etapa de rift Jurásico superior-Cretácico inferior. Una característica de las cuencas intracratónicas desarrolladas durante periodos ... -
Influencia del bitumen sobre la calidad de un reservorio siliciclástico: Aplicación al campo de Salam en el desierto occidental de Egipto
(Sociedad Geológica de España, 1998)Bitumen are rarely taken into account in the petrophysical characterization of reservoirs because they may be rather difficult to distinguish. This paper focuses on the effects of bitumen on the reservoir quality of the ... -
Materia orgánica en la Fm. Arenas de Utrillas de Picofrentes (provincia de Soria): diagénesis mineral y orgánica
(Sociedad Geológica de España, 1992)By Rock-Eval pyrolysis method, fluorescence, microscopy and S.E.M. with E.D.A.X. analysis, the organic matter rich horizonts at the top of Utrillas Fm. in Picofrentes log were studied. Ail samples are potencially good ... -
Materia orgánica y diagénesis de la formación de margas del Mas d'Ascla (Jurásico superior) en la cuenca del Maestrazgo (Cadena Ibérica oriental)
(Sociedad Geológica de España, 1999)The Mas d'Ascla marls Fm. (Upper Kimmeridgian to lowermost Tithonian) in the Maestrat Basin (Salzedella sub-basin, Castellò de la Plana) displays two organic-carbon-rich horizons which indicate anoxic conditions. The maximum ... -
Mineralogía de arenas y edad en una secuencia de superficies entre el río Tajo y los Montes de Toledo
(Sociedad Geológica de España, 1997)We study the heavy minerals in the fine sand from Bt horizons of soils developed in a serie of surfaces related to the Tajo river and Los Montes de Toledo. We found a sequence in the weathering degree of the detrital ... -
Nuevos datos sobre la petrología y procedencia de la Formación Miers Bluff, Isla Livingston, Islas Shetland del Sur
(Sociedad Geológica de España, 1994)The turbidites of the Miers Bluff Formation have been pelrologically analised and some compositional parameters have been calculated. The use of several ternary diagrams allow for some provenance speculations such as a ... -
La pirólisis Rock-EvaI en el caso de las muestras ricas en sales
(Sociedad Geológica de España, 1989)In this paper is presented a diffential behaviour during pyrolisis Rock-Eval between rich and non salt samples belonging to the Neogene Tertiary argillaceous sediments from the Tajo Basin -
Procesos de transformación y neoformación de esmectitas en los materiales volcanoclásticos de la isla de La Palma (Canarias)
(Sociedad Geológica de España, 1998)Clay minerals from the volcaniclastic deposits of the three different sedimentary settings (paleosols, continental lacustrine and transitional, fan delta) have been studied by X-ray, MEB y TEM. The clay fraction of this ... -
Propiedades petroestructurales de rocas madres de petróleo. Pizarras bituminosas del Cretácico superior de la cuenca vascocantábrica
(Sociedad Geológica de España, 1992)Black shales from Carai (Vizcaya) have been studied from the following points of view: mineralogy, geochemistry (pyrolysis rock-eval), porosimetry measurements and clay fabric. Data obtained suggest that: a) The presen ce ... -
Relaciones entre la diagénesis orgánica y mineral en rocas madre de cuencas lacustres: cuenca terciaria de Ribesalbes
(Sociedad Geológica de España, 1993)Lacustrine carbonate sediments from the Tertiary Basin of Ribesalbes (Castellón, Spain) were studied with the aim of determining the relationships between organic and mineral diagenesis. Petrological and geochemical data ...
