TL;DR: In this paper, the authors carried out a systematic analysis of modern instruments, including the laser grain size analyzer, X-ray computed tomography, scanning electron microscopy, XRD, Raman spectroscopy, gas chromatography, and isotope mass spectrometry, on the hydrate-bearing sediment samples recovered from the Shenhu area in the South China Sea in 2016.
Abstract: The characteristics of the hydrate-bearing layer are important parameters for gas hydrate exploration and exploitation, which can be provided by laboratory analysis. We have carried out a systematic analysis of modern instruments, including the laser grain size analyzer, X-ray computed tomography, scanning electron microscopy, X-ray diffraction (XRD), Raman spectroscopy, gas chromatography, and isotope mass spectrometry, on the hydrate-bearing sediment samples recovered from the Shenhu area in the South China Sea in 2016. We focused on the structure, hydration number, and gas composition of the gas hydrate samples. We also evaluated the effects of sediments on the occurrence and distribution of gas hydrate. Our results showed that the sediments are much finer than those recovered from the Shenhu area in 2007. Some samples are found to contain calcareous microfossils and foraminifera, which are beneficial for dispersed gas hydrate formation. Whereas the only visible hydrate sample (FC4) has not fo...

TL;DR: In this paper, an experimental device for in-situ monitoring of hydrate phase equilibrium is described, which comprises a housing body, a reaction vessel and a gas storage container, and the reaction vessel is connected with a computer microprocessor through an optical imaging system, a metering control system and a chromatographic analysis system.
Abstract: The invention relates to a test device, and especially relates to an experimental device for in-situ monitoring of hydrate phase equilibrium. The experimental device is characterized in that the device comprises a housing body; a reaction vessel and a gas storage container are arranged in the housing body and are communicated with each other by a gas feed pipe; the gas storage container is communicated with a gas bomb by a gas feed pipe and a pressure device; the reaction vessel is connected with a computer microprocessor through an optical imaging system, a metering control system and a chromatographic analysis system; and the reaction vessel is arranged in a water-bath jacket. Based on the experimental device, during the whole experiment process, the in-situ real-time recording of temperature data, pressure data, image data and chromatographic analysis data is carried out in one device by a computer system.

TL;DR: Wang et al. as discussed by the authors focused on the production behavior analysis and numerical predictions for 2017 tests in Shenhu Area, South China Sea, where the short-to mid-term production rate is estimated to drop from 3.5 to 2.0m3/d within 60 days, which is then extended for mid-to longterm (2-3 years) prediction of gas production.

TL;DR: In this article, the authors applied secondary ion mass spectroscopy (SIMS) to analyze the sulfur isotope composition (δ34S) of authigenic pyrite in addition to sulfur measurements of bulk sulfide and hand-picked pyritic aggregates from two seafloor sites, HS148 and HS217, in the Shenhu seepage area, South China Sea.
