Gas hydrate occurence and morpho-structures along Chilean margin: Characterization of gas hydrate reservoir from seismic analysis by Ivan de la Cruz Vargas Cordero



Characterization of gas hydrate reservoir from seismic analysis. The main results obtained from seismic analysis are shown in this book. This analysis giving us information regarding the seismic velocity distribution, geothermal gradient, variation of gas concentrations and a realistic estimate of gas-phase. The results are promising because an important gas reservoir was identified. Издательский Дом: VDM Verlag Dr. Müller.

Generally, gas hydrate deposits are investigated using geophysical methods. The seismic technique, which is the most used, allows detecting a clear indicator of the hydrate and free gas accumulations, known as bottom simulating reflector. Moreover, the seismic data provides information about the geometry of the main geological structures, allowing possible explanations of the presence/absence of gas hydrate.

There are three known structures of gas hydrates: Structure I (sI), structure II (sII) and structure H (sH). The MRI detects gas hydrate as a large drop in intensity between images of liquid water and solid hydrate. Hydrate formation was measured as the loss of MRI intensity as the liquid water converted to solid hydrate. Hydrogen in the solid hydrate has a short relaxation time and is not detected by the MRI by standard spin echo sequences (no signal above the background level).

INTRODUCTION This collaborative, international effort to compare gas hydrate reservoir simulators is designed to: (1) to exchange information regarding gas hydrate dissociation and physical properties enabling improvements in reservoir modeling, (2) to build confidence in all the leading simulators through exchange of ideas and cross-validation of simulator results on common datasets of escalating complexity, and (3) to establish a depository of gas.

Some cores are kept whole on a temporary basis (up to . m long) within the PCATS laboratory but most are cut into core sections for either long term storage or for rig site quantitative depressurization. Samples of gas are taken and analyzed throughout the depressurization process enabling the composition and concentration of gas hydrate in the sedimentary formation to be determined. Analysis of the records from the depressurization steps can provide both kinetic and thermodynamic evidence for the presence of gas hydrate.

During the last decades, the scientific community spent many efforts to study the gas hydrates in oceanic and permafrost environments. In fact, the gas hydrate occurrence has a global significance because it is a potential energy resource. Moreover, it may play a role in global climate change. The detection of a bottom-simulating reflector (BSR), by using seismic methods, has allowed to define the distribution of gas hydrate. In the last decades, along the Chilean continental margin the BSR is well reported by several geophysical cruises. In particular, the BSR is recognized along the accretionary prism. The main goal of this study is to map the gas hydrate occurrence along Chilean margin. The main results obtained from seismic analysis are shown in this book. This analysis giving us information regarding the seismic velocity distribution, geothermal gradient, variation of gas concentrations and a realistic estimate of gas-phase. The results are promising because an important gas reservoir was identified.
