COD and TOC measurement of subsurface brine of water-soluble natural gas.

open access: diamondJournal of the Japanese Association for Petroleum Technology, 1992
Applicability of TOC and COD values was examined as an indicator of organic contamination levels of subsurface brines from water-soluble natural gas fields. It was found that those brines have unique chemical characteristics as shown bellow, comparing with those seawaters.1) In TOC measurement, elimination of inorganic carbon by PH lowering made higher

Sonoluminescing air bubbles rectify argon [PDF]

open access: yes, 1997
The dynamics of single bubble sonoluminescence (SBSL) strongly depends on the percentage of inert gas within the bubble. We propose a theory for this dependence, based on a combination of principles from sonochemistry and hydrodynamic stability.

Genetic Types, Distribution Patterns and Enrichment Mechanisms of Helium in China’s Petroliferous Basins

open access: yesFrontiers in Earth Science, 2022
Helium is a strategic resource with many scientific, technical and industrial applications. However, despite its importance and scarcity, there is a lack of understanding on its origin, migration and accumulation processes.

Unconventional natural gas accumulation system

open access: yesNatural Gas Industry B, 2022
Unlike conventional natural gas accumulations, unconventional ones have obvious particularity in reservoir forming conditions, enrichment mechanism, distribution modes, prediction method, and exploration technology.

Optimal Control for Transmission of Water Pollutants [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2018
Pollutants are formed when oil, gas, chemical plants, etc. discharge their harmful waste materials into stream or other water bodies. In this paper, a mathematical model for water pollutants which are soluble and insoluble has been formulated as a system

Air/Sea Transfer of Highly Soluble Gases Over Coastal Waters [PDF]

open access: yes, 2020
The deposition of soluble trace gases to the sea surface is not well studied due to a lack of flux measurements over the ocean. Here we report simultaneous air/sea eddy covariance flux measurements of water vapor, sulfur dioxide (SO2), and momentum from ...
