... The seismic reflection of volcanic reservoir in deep basin is disordered due to the influence of energy shielding, which makes the exploration of volcanic reservoir very difficult. Aimed at the complex inner structure of deep volcanic reservoir with multi-phase superposition, TFEM (Time...

... Seismic characterization of volcanic reservoirs is a difficult task considering the low quality of seismic data. The reflection of volcanic rocks is always characterized by high amplitude and relatively low frequency compared with reflections of clastic sediments which makes the identification...

.... The discovery of the first volcanic reservoir in the eastern South China Sea has opened up a new field for the study of volcanic rock accumulation in the South China Sea, which plays an important role in the understanding of volcanic rock structure and the study of reservoir-forming rules in the South China Sea...

... Using common reflection angle migration (CRAM) which is an advanced beam migration, we successfully improved signal-to-noise ratio (SNR) and image continuity in the volcanic reservoir, offshore Myanmar. In this field, seismic imaging is challenging because high impedance contrast at the top...

... ABSTRACT Volcanic rock has enormous resource potential and has been the hotspot in the petroleum exploration for decades. Seismic characterization technology is a common method for volcanic reservoir prediction. However, its prediction accuracy is often limited by factors, such as complex...

... ABSTRACT Seismic characterization of volcanic reservoirs is a difficult task considering the complex depositional environment and low quality of seismic data. We developed a case study of characterizing volcanic reservoirs using geophysical methods in Junggar Basin, western China, which agrees...

... ABSTRACT The latest exploration results show it is widespread distribution of volcanic reservoirs in the Songliao Basin, Tarim Basin, Junggar Basin, and so on. Therefore, volcanic reservoirs are very important targets for oil and gas exploration. Hydrocarbon is produced where these volcanic...

... ABSTRACT Volcanic lithofacies is an important factor affecting reservoir performance and the basis of comprehensive evaluation of volcanic reservoir. Lithology and lithofacies of volcanic rock are very complex and change rapidly. At present, the use of one single identification technique leads...

... ABSTRACT The lithology of volcanic rock varies dramatically. The lithofacies are complicated. Thus, such type of reservoir shows strong heterogeneity. The conventional post-stack inversion can not effectively identify volcanic reservoir. However, pre-stack inversion can obtain more abundant...

... methods have been used for fracture detection, such as tectonic stress analysis, shear-wave splitting, coherency, structural curvature, etc. This paper describes how to best use azimuthal anisotropy in 3-D P-wave data to map the distribution of naturally fractures in a volcanic reservoir in the XJWZ...

.... Presently, laboratory study of rock physics characteristics of volcanic rocks is fewer, and there is very little published information available. In order to improve the ability of gas exploration and to discover more volcanic reservoirs, the laboratory measurements are carried out for some volcanic rock...

... multicomponent seismic experiments reveal some potential to use PS convertedwaves to image these targets, but the results are limited due to data quality issues. Recent advances in digital MEMS sensors have rekindled the interests of using convertedwave data to delineate these volcanic reservoirs in this area...

... ABSTRACT We introduce the methodology to image and characterize volcanic reservoirs and illustrate its application with the aid of a case study in XJWZ fault depression of the northern Songliao basin, China. Instantaneous spectral analysis and model based impedance inversion technique are used...
