The study of deepwater channels is important for the understanding sedimentary evolution mechanism and process marginal sea. In 2019, thick pore-filling gas hydrate with high saturation was firstly discovered in Quaternary sands Qiongdongnan Basin (QDNB), which expanded reservoir types hydrates South China Sea. However, distribution sand-related not well characterized, limits ability to predict...

Aquifer systems are considered in which measurements of logpermeability (Y) at a 1E-2 m support scale are unimodally distributed as taken within the 1E0 to 1E1 m scale of individual sand and gravel (sg) lithofacies, are weakly multimodal at the 1E1 to 1E2 m scale of assemblages of these facies, and are strongly multimodal at the 1E3 m scale of complexes of sg facies assemblages juxtaposed with ...

To improve the prediction of thin reservoirs with special geophysical responses, a geostatistical inversion technique is proposed based on an in-depth analysis theory inversion. This Markov chain Monte Carlo algorithm, to which we added contents facies-constrained. The feasibility and reliability results are demonstrated by sand bodies in braided river channel bars Xiazijie Oilfield Junggar Bas...

The occurrence of power law relationships in the spatial distribution of sedimentary lithotopes has been identified in both modern and ancient carbonate depositional bodies. In this study, facies patterns and their spatial relationships are investigated quantitatively in an Arabian Gulf shallow subtidal carbonate ramp setting, using a synergy of IKONOS satellite imagery and vessel-based acousti...

Seismic hazard analysis of vulnerable countries on the Alpine-Himalayan belt has great importance to be considered. Recently, Iran as one of the countries located on the stated belt has experienced a few number of severe earthquakes. A wellestablished index of how earthquakes affect buildings is by assessing probable Peak Ground Acceleration (PGA) which can be estimated by past events. For this...

Abstract Shale-rich reservoirs present a long-standing challenge for reservoir geologists because the clay minerals often induce large-scale heterogeneity in pore system. This work aims to understand impact of distribution and mineralogy which would enhance predictability best facies. We integrate seismic, well-log datasets investigate petrophysical characteristics clay-rich Cenomanian Clastics...

A new approach is presented for inverse modeling to reconstruct continuous features in space, such as channels, that exhibit sparseness in a complementary basis (e.g. a Fourier basis) using observations in spatial domain. Continuity in space is used to constrain the solution to be sparse in the discrete cosine transform (DCT) domain. The DCT is used to effectively reduce the dimension of the se...

The influence of soil-structure interaction in the analysis and design of a 6-storey and basement reinforced concrete frame building is investigated. Models simulating two different conditions: namely soil-structure interaction, and fixed-base behavior are considered. The influence of the soil structure interaction in the dynamic behavior of the structure is reflected in an increase in the vibr...
