Special Issue Information

Dear Colleagues,

Gas hydrate has attracted attention as a potential unconventional geological energy, with numerous efforts having been devoted towards realizing the commercial production of gas hydrate. However, there are many factors restricting this development. This Special Issue aims to present recent advances in gas hydrate development. We invite you to submit comprehensive review papers and original articles coving topics including, but not limited to, the following:

  • Gas hydrate reservoir structure characterization;
  • Mechanical tests and constitutive models of gas hydrate-bearing sediments;
  • Multiphase seepage mechanism in gas hydrate reservoirs;
  • Numerical simulation methods of gas hydrate development;
  • Novel gas hydrate exploitation methods;
  • Geological hazards and environmental effects relative to gas hydrate development.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly journal published by MDPI.

In order to study the macro-meso shear mechanical characteristics of natural gas hydrate-bearing sediments, the direct shear simulations of natural gas hydrate-bearing sediment specimens with different saturations under different normal stress boundary conditions were carried out using the discrete element simulation program of particle flow, and the macro-meso shear mechanical characteristics of the specimens and their evolution laws were obtained, and their shear damage mechanisms were revealed. The results show that the peak intensity of natural gas hydrate-bearing sediments increases with the increase in normal stress and hydrate saturation. Hydrate particles and sand particles jointly participate in the formation and evolution of the force chain, and sand particles account for the majority of the force chain particles and take the main shear resistance role. The number of cracks produced by shear increases with hydrate saturation and normal stress. The average porosity in the shear zone shows an evolutionary pattern of decreasing and then increasing during the shear process. Full article
