... Gas hydrates may form from dissolved gas during cold-water (2– 5°C) injection in shallow offshore undersaturated oil reservoirs. In this work, we instrumented core samples with geophysical sensors to detect fluid phase transitions to a solid phase. This allows determining the conditions...

... Accurate identification and quantitative evaluation of gas hydrate from well-logs are the basis of gas hydrate geophysical exploration. Resistivity and sonic are two relatively accurate and reliable logging data for in-situ identification and evaluation of hydrate reservoir due...

... ABSTRACT Quantitative characterization of gas hydrate-bearing sediments from geophysical measurements has been of long-standing interest for gas hydrate evaluation and exploitation. Gas hydrates exhibit several microscopic morphologies within the sediments, subsequently affecting their elastic...

... ABSTRACT Gas hydrate residing in pore spaces and fractures are two representative distributions in general sediment settings. Morphology of hydrate distribution is essential for assessing its resource potential, understanding its formation, and determining optimum strategies for exploitation...

Additionally, within the accretionary prism, the area contains high concentrations of methane hydrates with clear observational records of continuous methane seepage. In the event of a major earthquake, the gas-hydrate stability field is likely...

... ABSTRACT This study aims to improve the imaging and detection of gas hydrate stability zones, particularly in regions that lack the presence of a Bottom Simulating Reflector (BSR) in the seismic data. Rock physics modeling techniques and a variety of seismic attribute studies have been...

... ABSTRACT The present study deals with delineation of lateral extent of BSR along a line of 2D seismic reflection data in the Krishna-Godavari basin, India passing through NGHP-01-4A and NGHP-01-11A wells. The investigation is further extended to estimate gas hydrate saturation at corresponding...

... ABSTRACT Seismic attributes have become successful in illuminating subsurface features and are widely used by interpreters for identifying potential hydrocarbon reservoirs. A case study is presented in the Mahanadi basin lying in the eastern Indian margin, where gas hydrate has been detected...

... ABSTRACT Gas hydrates reservoirs are considered as viable energy resource to be utilised in the near future. Deep sea pockmarks underlain by pipe structures that contain hydrates are abundant along the Norwegian continental margin. The Nyegga region, situated on the western Norwegian...

... Summary Naturally occurring gas hydrates contain significant amounts of natural gas which might be produced in the foreseeable future. Thus, it is necessary to understand the pore-space characteristics of hydrate reservoirs, especially the pore-scale distribution of hydrates...

These instruments are installed on NEPTUNE Canada’s ocean floor network on the Cascadia margin. Here, gas hydrates occur and they have the property of stiffening marine sediment...

... Summary Gas hydrate has recently received much attention as a potential energy source. To determine the candidate sites for the production of gas hydrate, the distribution and saturation which are closely related its reserves should be preferentially predicted. The saturation of gas hydrate...
