“…For detritus deposition with flowing water as the transport medium, the hydrodynamic force determines the particle size, movement mode, and deposition mode of the rock particles [31,32]. Strong hydrodynamic conditions can transport large rock particles away from their provenance via rolling and jumping.…”

In order to finely characterize the physical properties and seepage characteristics of underwater distributary channel sand bodies in a braided river delta, the particle size distribution, mercury injection, and withdrawal of low, medium, high, and extra-high permeability core samples from the TIII reservoir from 15 core wells in the Sangtamu Oilfield were compared. The pore-throat characteristics of the rocks with different deposition modes and their effects on the fluid seepage were analyzed from the perspective of the deposition processes. The statistical results revealed that the rocks formed in a continuous and stable strong hydrodynamic environment were coarse grained. The seepage capacities of the rock increased as the maximum throat radius connecting with the pores increased. The mercury withdrawal efficiency decreased as the difference between the throat radius and pore radius increased. The percentage of the throat volume without effective seepage to the total volume of the pore-throat system increased as the permeability of the samples increased. Therefore, when characterizing reservoirs based on the porosity and permeability, it is important to differentiate the energy of the hydrodynamic depositional environment of a monogenic sand body in order to improve the accuracy of the understanding of the reservoirs.

This study uses a thorough grain size analysis approach to the depositional environment in the Thamirabarani River basin, specifically in the Srivaikundam district of Tamil Nadu, India. There is a significant lack of research on the depositional settings and sediment features unique to the Thamirabarani River basin, even though there have been numerous sediments studies conducted in other river basins. Consequently, the purpose of this study is to investigate the depositional habitats and sediment characteristics of this area. The majority of the 18 sediment samples were determined to be medium- to fine-grained and poorly sort-able after extensive analysis using granulometric research and sieve methods. The low-energy formation process took place in a largely fine-grained or very fine-grained sandy soil, as indicated by the sediments platykurtic and mesokurtic morphologies. The depositional habitats within the region can be better understood by classifying the soil based on ternary plots of clay, silt, and sand, such as particle distribution curve. Furthermore, comparison with a unified soil classification chart aids in further categorizing the soil types. Soils can be classified and the depositional settings of different landscapes, such as rivers, estuaries, beaches, and aeolian terrains, can be better understood with the use of this comprehensive grain size study. Another interesting aspect of the Thamirabarani River basin sediment movement and deposition is the slow breakdown of rocks, especially feldspar and quartz, as they move through rivers and streams.
