Evolution in the use of natural building stone in Madrid, Spain [PDF]

open access: yes, 2013
Many types of stone have been used for construction in Madrid. In historical times, their use was determined by the proximity of the geological resources, the ease of quarrying and transportation links to the city. More recently, as transport connections

Association of the Flow Units with Facies Distribution, Depositional Sequences, and Diagenetic Features: Asmari Formation of the Cheshmeh-Khush Oil Field, SW Iran [PDF]

open access: yesJournal of Petroleum Science and Technology, 2017
The Oligo-miocene Asmari formation is one of the most important hydrocarbon reservoirs in the southwest of Iran. In order to evaluate reservoir quality and the factors controlling reservoir properties, detailed geological and petrophysical studies were ...

Sedimentological and biofabric patterns for hybrid coquina deposits: Insights from wave tank experiments

open access: yesSedimentology, Volume 72, Issue 6, Page 1992-2024, October 2025.
ABSTRACT Hybrid bioclastic/siliciclastic coquinas are sedimentary accumulations typical of coastal‐ and shallow‐water settings, where wave breaking, longshore drift and wave shoaling drive sediment transport and control the final accumulations. These processes resulted in thick packages of sediments, as identified in the Lower Cretaceous depositional ...

Unstructured Grid Based Joint Inversion of DC Resistivity and Gravity Data: Adaptive FCM Assisted Model Coupling and Quantitative Similarity Analysis

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Many geophysical studies have highlighted the limitations of relying on a single geophysical data set to understand subsurface conditions. Often, individual inversions yield inconsistent geologic models. To address this issue, this study integrates direct current (DC) resistivity and gravity data within a joint inversion (JI) framework.

Fully Integrated Hydrocarbon Reservoir Studies: Myth or Reality? [PDF]

open access: yes, 2010
: Problem statement: In the petroleum industry and especially during reservoir studies, data coming from different disciplines must be combined in order to generate a model that is representative of the reservoir being studied and can be used for ...

High Impedance Mudstone Associated With Sand Injection Complexes: Significance for Basin‐Scale Fluid Retention and Escape

open access: yesBasin Research, Volume 37, Issue 5, September–October 2025.
The diagram on the left is a section view illustrating the centroid concept, whereby a permeable lithology (yellow, sand) can facilitate fluid escape from low permeability host mudstones (grey). The cartoon section on the right illustrates the location of focused fluid escape along injectites (in red) that straddles a primary overpressure zone ...
