  1. 1. Effect of Petrophysical Parameters on Seismic Waveform Signatures : Review of Theory with Case Study from Frigg Delta Oil Field, Norway

    University essay from Uppsala universitet/Geofysik

    Author : Gardar Gislason; [2016]
    Keywords : AVO; poroelasticity; AVFO; WIFF; seismic attenuation; seismic dispersion; AVO; poroelasticitet; AVFO; WIFF; seismisk dampning; seismisk dispersion;

    Abstract : Conventional AVO analysis has been used for the past 4 decades to aid in locating oil and gas reservoirs for extraction. It is, however, not possible to use it to acquire information on the porosity of the rock, the fluid saturation or other important petrophysical parameters. READ MORE

  2. 2. Semi-Analytical Finite Element method for guided waves in civil engineering plate-like structures

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Christian Nielsen; [2015]
    Keywords : seismics; structural health monitoring; lamb waves; SAFE; semi analytical finite element; wave guide finite element; non destructive testing; civil engineering; ultrasound; ultrasonography; comsol; wave guide; plate; Technology and Engineering;

    Abstract : Guided waves have a signicant potential for Structural Health Monitoring (SHM) and Non-Destructive Testing (NDT) due to their relatively long distance of propagation and sensitivity to discontinuities along the propagation path, anywhere through the material thickness. The inability to model wave guides of arbitrary cross-section using current matrix methods, has led to the development of a technique called Semi-Analytical Finite Element (SAFE). READ MORE
