AVA-study of shallow marine unconsolidated sediments using UHR multichannel seismoacoustic dataset acquired with a deep-towed system

open access: yes, 2015
Combination of P-wave velocity analysis and AVA-study of seismoacoustic data can provide information about Vp, Vs, bulk density ρ and attenuation of the media. However, efficient AVA-analysis of ultra-high resolution dataset requires minor distortions in

Bayesian Estimation of Reservoir Properties by Means of Wide-angle AVA Inversion and a Petrophysical Zoeppritz Equation

open access: yes, 2016
We apply a target-oriented amplitude versus angle (AVA) inversion to estimate the petrophysical properties of a reservoir in offshore Nile delta. A linear empirical rock-physics model derived from well log data provides the link between the petrophysical

Spatial delineation, fluid-lithology characterization, and petrophysical modeling of deepwater Gulf of Mexico reservoirs through joint AVA deterministic and stochastic inversion of 3D partially-stacked seismic amplitude data and well logs [PDF]

open access: yes, 2006
This dissertation describes a novel Amplitude-versus-Angle (AVA) inversion methodology to quantitatively integrate pre-stack seismic data, well logs, geologic data, and geostatistical information.

Identification of Gas-hydrates and Free Gas Zones using Acoustic Impedance Inversion Integrated with AVA Analysis

open access: yes
The methane hydrates are often recognized in seismic data by means of identifying a distinct seismic reflection called the Bottom Simulating Reflector (BSR).

Two intra-articular regimens of administration of tramadol after arthroscopic surgery in the horse: effects on pain control

open access: yes, 2017
The analgesic efficacy of intra-articular 50 mg tramadol is documented in human surgery. We aim to compare the analgesic effect of tramadol administered at two different doses in horses after arthroscopy.

Post-stack inversion of seismic reflection data from the belvoir coalfield [PDF]

open access: yes, 1995
Post-Stack inversion of reflection data in seismic exploration can be used to obtain detailed information about lithology variations in the zone of interest. Generalized Linear Inversion (GLI) has previously been applied as a useful tool to achieve this.

Three-dimensional geoacoustic perturbative inverse technique for the shallow ocean water column [PDF]

open access: yes, 2013
textThis work focuses on developing an inversion scheme to estimate water-column sound-speed fields in three dimensions. The inversion scheme is based on a linearized perturbative technique which utilizes estimates of modal travel times.

An adaptive multiscale algorithm for efficient extended waveform inversion

open access: yes, 2017
Subsurface-offset extended full-waveform inversion (FWI) may converge to kinematically accurate velocity models without the low-frequency data accuracy required for standard data-domain FWI.
