Hybrid-Driven High-Resolution Prestack Seismic Inversion
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Prestack seismic inversion is considered among the most frequently utilized techniques for reservoir characterization. However, the resolution of the inverted parameters, such as P-, S-wave velocity, and density, is low due to the limited bandwidth and ...

Simultaneous prestack seismic inversion in a carbonate reservoir [PDF]
REM: International Engineering Journal, 2018 We applied a method of Simultaneous Prestack Seismic Inversion (SPSI) in a hydrocarbon field located in the Campos Basin, Brazil. The goal was to study the application of this method to Albian carbonate rocks of the Quissamã Formation.

Monitoring geological storage of CO2 using a new rock physics model [PDF]
Scientific Reports, 2022 To mitigate the global warming crisis, one of the effective ways is to capture CO2 at an emitting source and inject it underground in saline aquifers, depleted oil and gas reservoirs, or in coal beds.

Amplitude Versus Angle (AVA) feature restoration in prestack gathers via dictionary learning. [PDF]
PLoS ONEWith the expansion of oil and gas exploration into deep and complex reservoirs, the prestack amplitude versus angle (AVA) inversion technique faces challenges due to amplitude attenuation and phase distortion caused by formation absorption effects, which

Prestack seismic inversion using a Rytov-WKBJ approximation
Geophysical Journal International, 2021 Summary Approaches to seismic modeling using integral methods, notably Born-WKBJ (Wentzel-Kramers-Brillouin-Jeffreys), have seen an increase in applications in geophysical prospecting and near-surface exploration. Moreover, due to its linearity characteristic, which can fast and efficiently simulate full-waveform information, the Born ...

Seismic characterization of carbonate stringers using machine learning techniques: an example from the western flank of South Oman Salt Basin [PDF]
Scientific ReportsCarbonate stringers are defined as a slab of carbonate bodies encased inside salt. In Oman, the intra-salt carbonate stringers are a very common target, especially in South Oman Salt Basin (SOSB).

Direct inversion for reservoir parameters from prestack seismic data [PDF]
Journal of Geophysics and Engineering, 2020 Abstract Reliably estimating reservoir parameters is the final target in reservoir characterisation. Conventionally, estimating reservoir characters from seismic inversion is implemented by indirect approaches. The indirect estimation of reservoir parameters from inverted elastic parameters, however, will produce large bias due to the ...
