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.

Characterization of complex fluvial-deltaic deposits in Northeast India using Poisson impedance inversion and non-parametric statistical technique [PDF]

Scientific Reports, 2022
Characterizing complex fluvial-deltaic deposits is a challenging task for finding hydrocarbon discoveries. We described a methodology for predicting the hydrocarbon zones from complex well-log and prestack seismic data.

A New Stochastic Process of Prestack Inversion for Rock Property Estimation

Applied Sciences, 2022
In order to enrich the current prestack stochastic inversion theory, we propose a prestack stochastic inversion method based on adaptive particle swarm optimization combined with Markov chain Monte Carlo (MCMC).

Application of Facies Controlled Prestack Inversion Technology in Prediction of Deep Tight Gas in Continental Faulted Basin

Geofluids, 2022
It is difficult to predict tight sandstone gas in continental rift basin because of complex deep structure, fast transformation of sedimentary facies, large lateral variation of reservoir thickness, and tight and strong heterogeneity.

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 ...

Amplitude Versus Angle (AVA) feature restoration in prestack gathers via dictionary learning. [PDF]

PLoS ONE
With 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

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.

Seismic characterization of carbonate stringers using machine learning techniques: an example from the western flank of South Oman Salt Basin [PDF]

Scientific Reports
Carbonate 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).
