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

    Master-uppsats, Uppsala universitet/Geofysik

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

    Sammanfattning : 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. LÄS MER

  3. 2. A High Order Finite Difference Method for Simulating Earthquake Sequences in a Poroelastic Medium

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Kim Torberntsson; Vidar Stiernström; [2016]
    Nyckelord :numerical analysis; numerical methods; numerical modeling; SBP-SAT; finite differences; high performance computing; geophysics; geomechanics; poroelasticity; fault mechanics; induced seismicity;

    Sammanfattning : Induced seismicity (earthquakes caused by injection or extraction of fluids in Earth's subsurface) is a major, new hazard in the United States, the Netherlands, and other countries, with vast economic consequences if not properly managed. Addressing this problem requires development of predictive simulations of how fluid-saturated solids containing frictional faults respond to fluid injection/extraction. LÄS MER
