Identification of the geological facies and their distribution from seismic and other available geological information is important during the early stage of reservoir development (e.g. decision on initial well locations). Traditionally, this is done by manually inspecting the signatures of the seismic attribute maps, which is very time-consuming. This paper proposes an application of the Expec...

Evaluating any subsurface CO2 storage site comprises the reservoir, seal, and overburden investigation to mitigate injection storage-related complications. The Upper-Middle Jurassic Sognefjord, Fensfjord, Krossfjord formation sandstones are potential reservoirs at Smeaheia area, northern North Sea. area is located east of Troll oil gas field. Upper organic-rich Heather Draupne Formation shales ...

Reservoir characterization on offshore fields often faces specific challenges due to limited or unevenly distributed well data. The object of this study is the North Adriatic poorly consolidated clastic reservoir characterized by high porosity. seismic data indicate notable differences in quality spatially. only two wells field drilled best area. Seismic data, characterization, and accurate int...

background: interest in tatera indica rodent arises mostly because it is believed that this species is survived among four subspecies reported from iran, two of which exist in khuzestan province. in addition, it might has a role as res­ervoir hosts of zoonotic cutaneous leishmaniasis in the transmission of leishmania major in some of the widespread asian foci including southwestern iran. method...

Color is the critical factor in seismic data interpretation and geological targets visualization. And recently, ideas of color blending have brought the enlightenment in attribute combinations for reservoir characterization in petroleum engineering. In this paper, we present this approach of color blending in different color modes and its application in subsurface channel detection by using sei...

spectral decomposition or time-frequency representation (tfr) is a powerful tool for analyzing time varying nature of seismic data. mapping of a one dimensional seismic time trace to a two dimensional function of time and frequency reveals some characteristics of seismic signals that are not available in only time or frequency representations. this approach has been widely used in seismic explo...

The aim of seismic inversion is mapping all of the subsurface structures from seismic data. Due to the band-limited nature of the seismic data, it is difficult to find a unique solution for seismic inversion. Deterministic methods of seismic inversion are based on try and error techniques and provide a smooth map of elastic properties, while stochastic methods produce high-resolution maps of el...

lithofacies identification can provide qualitative information about rocks. it can also explain rock textures which are importantcomponents for hydrocarbon reservoir description sarvak formation is an important reservoir which is being studied in the marun oilfield, in the dezful embayment (zagros basin). this study establishes quantitative relationships between digital well logs data androutin...
