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

3. 2. Effects of simulated rainfall intensity on water flow through soil in two tillage systems

   University essay from SLU/Dept. of Soil and Environment

   Author : Maria Sandin; [2012]
   Keywords : heavy clay soils; reduced tillage; macropore flow; rainfall simulator; dual-permeability model;

   Abstract : Diffuse losses of phosphorus from agricultural land to freshwater reservoirs have gained increasing interest in later years. Resent research suggests that phosphorus is mainly transported from the fields through macropores, and that soil under reduced forms of tillage can develop a higher macroporosity and thus an increased risk of phosphorus leaching compared to conventionally tilled soil, because of the more rapid flows of water through the soil.
