1. 1. Giant Oil Fields - The Highway to Oil : Giant Oil Fields and their Importance for Future Oil Production

   Författare :Fredrik Robelius; Kjell Aleklett; Robert Hirsch; Uppsala universitet; []
   Nyckelord :Engineering physics; giant oil fields; URR; future oil production; peak oil; forecast; Teknisk fysik;

   Sammanfattning : Since the 1950s, oil has been the dominant source of energy in the world. The cheap supply of oil has been the engine for economic growth in the western world. Since future oil demand is expected to increase, the question to what extent future production will be available is important. LÄS MER

3. 2. Chemical exposures, biological monitoring and cancer risks in Swedish aluminium foundries and remelting plants

   Författare :Håkan Westberg; Hans Welinder; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : In aluminium foundries and remelting plants, a wide range of chemical agents are formed and emitted, including some highly toxic organochlorine compounds. This thesis explores emissions and exposures, as well as worker risk of porphyria and cancer. LÄS MER

4. 3. Parameters Controlling Distribution of Diagenetic Alterations within Fluvial and Shallow Marine Sandstone Reservoirs : Evidence from the Libyan Basins

   Författare :Muftah Khalifa; Hemin Koyi; Joao Marcelo Medina Ketzer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diagenesis; Structural setting; Depositional facies; Basin thermal history; Ther- mal Hot basinal brines; Fluid inclusions; Raman Spectrometry; Stylolites; Hydro-carbon migration; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

   Sammanfattning : This thesis demonstrates that geological setting, depositional facies, open system flux of hot basinal brines and descending of shallow waters have a strong impact on the distribution of the diagenetic alterations within continental and paralic/shallow marine sandstones which in turn control the quality and heterogeneities of the reservoirs.Geological setting controls the mineralogical and textural maturity of sandstone, whereas depositional facies control the pore water chemistry (marine, brackish or meteoric), sedimentary texture and sand body geometry.

5. 4. Seismic Investigations at the Ketzin CO2 Injection Site, Germany: Applications to Subsurface Feature Mapping and CO2 Seismic Response Modeling

   Författare :Sayed Hesammoddin Kazemeini; Christopher Juhlin; Sergey Fomel; Milovan Urosevic; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic resolution; Spectral blueing; CO2 seismic response; Continuous Wavelet Transform Decomposition; 3D seismic baseline; CO2SINK project; Solid earth physics; Fasta jordens fysik; geofysik; med inriktning mot fasta jordens fysik; Geophysics Specialized In Solid Earth;

   Sammanfattning : 3D seismic data are widely used for many different purposes. Despite different objectives, a common goal in almost all 3D seismic programs is to attain better understanding of the subsurface features. LÄS MER

7. 5. Dielectric Properties of Liquid-Impregnated Porous Solids

   Författare :Bo Nettelblad; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluid-solid interface; porous microstructure; temperature; ion-containing liquid; transport properties of porous media; brine; salinity; electric conduction; models of composite media; interface phenomena; dielectric relaxation; rock;

   Sammanfattning : Dielectric spectroscopy is a versatile tool that can often be used as a non-destructive, indirect way of measuring other important properties (such as content of crude oil or degree of curing of a resin). The dielectric properties of materials are thus of interest in several circumstances and not only for materials used for electrical purposes (such as electrical insulation). LÄS MER
