Journal Article: An Integrated Study Method For Exploration Of Gas Hydrate Reservoirs In Marine Areas

Abstract
We propose an integrated study method for exploration of gas hydrate reservoirs in marine areas. This method combines analyses of geology, seismology, and geochemistry. First, geological analysis is made using data of material sources, structures, sediments, and geothermal regimes to determine the hydrocarbon-formation conditions of gas hydrate in marine areas. Then analyses of seismic attributes,such as BSR, AVO, and BZ as well as forward modeling are conducted to predict the potential existence of hydrate and its free gas. In conj unction with geological conditions, the hopeful zones of gas hydrate reservoirs can be estimated. Finally, based on the analysis of geochemical anomalies to the main components, such as methane and hydrocarbon series, an integrated assessment of prospective gas hydrate reservoirs in study areas can be performed. Results of field practice show that this integrated method is effective and feasible. It provides a new research approach for exploration of gas hydrate reservoirs in marine areas.
