“…It is used for imaging discontinuity related to faulting or stratigraphy in seismic data. Variance attribute is proven to help in imaging of channels, fault zones, fractures, unconformities and the major sequence boundaries [25]. The darkest regions in the seismic section, which make vertical strips, may be interpreted as faults or fractures.…”

In this study, we have extracted and analyzed four seismic attributes of Akos oil field to obtain more information about the structures, stratigraphy and hydrocarbon potential of the Akos field from available seismic and a suite of well logs data. Two lithology and reservoirs were delineated from the well logs. Two horizons and growth faults were identified in the seismic sections. For a comprehensive analysis of the structural and stratigraphic understanding of the reservoirs, four seismic attributes variance edge, sweetness, root mean square and relative acoustic impedance were applied to the seismic data. The Variance edge analysis was used to delineate the prominent and subtle faults in the area. The high sweetness regions in the seismic data indicate high amplitude which indicates the presence of hydrocarbon-bearing sand units. The root mean square amplitude analysis also indicates the presence of hydrocarbon in seismic data. The relative acoustic impedance analysis was used for delineating lithology variation in the seismic sections. The result of the seismic attribute analysis has shown that the Akos field has good hydrocarbon prospects.

“…Late Cretaceous–Cenozoic basins along the East Asian continental margin have attracted much attention for hydrocarbon exploration and evaluation over the past few decades (Gongcheng, Li, Lei, & Zhao, ; Jiang, Li, Chen, Zhang, & Wang, ; G. H. Lee, Kim, Shin, & Sunwoo, ; Pigott, Kang, & Han, ; Ye, Qing, Bend, & Gu, ; Zhou, Zhao, & Yin, ). East China Sea Basin (ECSB), one of the petroliferous sedimentary basins in the East Asia, is composed of elongated depressions aligned parallel to the subduction zone of the western Philippine Sea Plate with the Taiwan–Sinzi Belt and Ryukyu Arc (Figure ; Wageman, Hilde, & Emery, ).…”

Structural evolution of two‐stage rifting in the northern East China Sea Shelf Basin

et al. 2018

This study focuses on the stratigraphic correlation and structural evolution of the Ieodo and Jeju basins in the northern East China Sea Shelf Basin (ECSSB), which are compared to the Changjiang and Xihu depressions, respectively. Based on multi‐channel seismic reflection data, Cenozoic sedimentary successions resting on the acoustic basement in both basins can be divided into multiple syn‐ and post‐rift units. Basement‐involved structures exhibit different orientations, that is, E–W (ENE–WSW) and NE–SW trending structures in the Ieodo and Jeju basins, respectively. They represent the development of two‐stage rifting. The first rift stage began in the Palaeocene and was only restricted to the Ieodo Basin located west of the Hupijiao Rise. The second rift stage subsequently occurred in the Jeju Basin located east of the Hupijiao Rise during the late Eocene to Miocene. The Eocene post‐rift unit of the Ieodo Basin was uplifted while the Jeju Basin was subsided by bounding faults. The sequential development of rift structures in the basins suggests eastward migration of the Cenozoic rifting in the northern ECSSB. The NE‐trending rift structure of the Jeju Basin parallel to the subduction zone of the Pacific Plate suggests that the second rift stage possibly evolved under the influence of the back‐arc extensional regime. The Hupijiao Rise between the Ieodo and Jeju basins was possibly a geologic basement in the Palaeocene and was an uplifted remnant caused by footwall exhumation during the second rift stage of the Jeju Basin.

“…As elevadas amplitudes presente nos refletores do primeiro e segundo arranjo corroboram a identificação de um embasamento acústico remetendo a feição de paleocalha do antigo canal principal em escala similar ao atual (Cooper et al, 2016;Damuth et al, 1983;Peakall et al, 2007). A identificação dessas feições caracteriza o desenvolvimento de paleofeições, as quais também podem estar associadas as mudanças na configuração neotectônica e alterações abruptas na descarga fluvial com a ação de fenômenos favorecidos pelas condições de maré como o fenômeno da pororoca típico em regiões com a influência de macromaré (Pigott et al, 2013;Santos et al, 2002;Smith et al, 1993).…”

RESUMO.A Baía de Macapá, por estar inserida a zona de médio estuário do Rio Amazonas, apresenta vestígios de alterações morfológicas diferenciadas pela forte dinâmica em um curto intervalo de tempo. O reflexo de tais alterações pode ser observado nas modificações morfoestruturais presentes no leito e subsuperfície. A análise dos perfis sísmicos em alta resolução pelo intervalo de frequência de 0,7 kHz a 12,0 kHz revela que as características apresentadas nas formas de fundo desencadeiam os processos modeladores do padrão de reflexão observados nos refletores em subsuperfície. Através desta relação foi possível identificar a predominância de cinco formas de fundo, quatro unidades estruturais e cinco sismofácies com o destaque para a identificação de uma feição de paleocanal. Observou-se que as variações morfológicas do leito são influenciadas pela constante atuação dos processos hidrodinâmicos e sedimentares ocorrentes periodicamente e vice-versa, corroborando para correlação entre as feições superficiais de fundo e as feições em subsuperfície.Palavras-Chave: Morfologia, formas de fundo, sismofácies, paleocanal.ABSTRACT. The Macapá Bay, because it is inserted in the middle estuary zone of the Amazon River, presents evidences of different changes in a short time. The reflex of such changes can be observed in morphostructural modifications present in the bed and subsurfaces. The analysis of the high-resolution seismic profiles through on frequency range of 0.7 kHz to 12.0 kHz reveals that the features presented in the bedforms trigger the reflection pattern modelers processes observed in the subsurface reflectors. Through this relationship, it was possible to identify the predominance of five bedforms, four structural units and five seismic facies with highlight for the identification of a paleochannel feature. It was observed that the morphological variations of the bed are influenced by the constant actuation of the hydrodynamic processes and sedimentary that occur periodically and vice versa, corroborating to correlation between the superficial bottom features and the subsurface features.
