A novel directional-oriented method for predicting shear wave velocity through empirical rock physics relationship using geostatistics analysis.

This study attempts to design a novel direction-oriented approach for estimating shear wave velocity (V) through geostatistical methods (GM) using density employing geophysical log data. The research area involves three hydrocarbon wells drilled in carbonate reservoirs that are comprised of oil and water. Firstly, V was estimated using the four selected empirical rock physics relationships (ERR) in well A (target well), and then all results were evaluated by ten statistical benchmarks.

The deterioration of groundwater quality by seawater intrusion in the Chao Phraya River Basin, Thailand.

The Chao Phraya River Deltaic Plain is the largest basin in Thailand and the second largest one in Southeast Asia after the Mekong River Delta. In recent decades, the groundwater quality in the Lower Chao Phraya River Basin in Thailand has deteriorated due to salinization caused by seawater intrusion. In the present study, hydrogeochemical and statistical methods were employed to determine the hydrochemical characteristics of the groundwater and to investigate the possible sources of salinity in the study region for the years 2008 and 2020.

A comprehensive study of the parameters affecting the stable isotopes in the precipitation of the Bangkok metropolitan area using model-based statistical approaches.

This study determined the main local and regional parameters affecting the stable isotopes (O, H) in the Bangkok precipitation and developed the Bangkok meteoric water line (BMWL) (H = (7.68 ± 0.07) O + (7.
