Executive Summary : | The aim of this project is to investigate the stability of gas hydrate-bearing sediments in the Indian offshore region with the goal of enhancing gas production. The study will comprise a thorough examination of the geological features of the area and an evaluation of the mechanical characteristics of the hydrate-bearing sediments. The National Gas Hydrate Program (NGHP) of India conducted two expeditions, NGHP-01 in 2006 and NGHP-02 in 2015, and discovered hydrates in the K-G, Mahanadi, and Andaman basins. Based on the success of these expeditions, India is preparing for a third expedition, NGHP-03, that will include pilot testing in the K-G basin. However, further research is necessary to completely understand the technical, economic, and environmental feasibility of gas hydrate production. Therefore, this project will investigate the stability of hydrate-bearing sediments from the K-G, Mahanadi, and Andaman basins under triaxial loading conditions. This study will also investigate the change in the physico-mechanical properties of hydrate bearing sand during CH4-CO2 swapping process. The project will include planned experimental and numerical investigations into the deformation properties of sediments containing hydrates, particularly during dissociation. The outcomes of this research can enhance the efficiency and safety of gas hydrate drilling and production operations and contribute to expanding the knowledge base in this field. To maximize the impact of the research outcomes, the project will disseminate its findings through peer-reviewed publications, conferences, and workshops, and work with industry experts to apply the findings in practical scenarios. The outcomes will improve the understanding of the stability of hydrate-bearing sediments in the Indian offshore region and assist in the planning and execution of the NGHP expedition - 03. |
