2. 1. Diagenesis and Reservoir-Quality Evolution of Paralic, Shallow Marine and Fluvio-lacustrine Deposits : Links to Depositional Facies and Sequence Stratigraphy

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sandstone; Diagenesis; paralic; shallow marine and fluvio-lacustrine; reservoir quality; sequence stratigraphy; Solid earth geology and petrology; Berggrundsgeologi och petrologi;

   Abstract : Linking diagenesis to depositional facies and sequence stratigraphy enables better prediction of spatial and temporal distribution of diagenetic alterations, and thus of evolution of reservoir quality in sandstones. This thesis demonstrates that employing this approach is possible because depositional facies and sequence stratigraphy can provide useful information on parameters controlling the near-surface diagenesis, such as changes in: (i) pore-water chemistry, (ii) residence time of sediments under certain geochemical conditions, (iii) detrital composition and proportion of extra- and intra-basinal grains, and (iv) types and amounts of organic matter.

4. 2. Impact of Diagenetic Alterations on Reservoir Quality and Heterogeneity of Paralic and Shallow Marine Sandstones : Links to Depositional Facies and Sequence Stratigraphy

   Author : Khalid Al-Ramadan; Sadoon Morad; Luiz Fernando De Ros; Uppsala universitet; []
   Keywords : Bedrock geology; Siliciclastic; Diagenesis; Sequence stratigraphy; Paralic and shallow marine; Heterogeneity; Reservoir quality; Berggrundsgeologi;

   Abstract : This thesis constrains the distribution of diagenetic alterations and their impact on reservoir-quality and heterogeneity evolution pathways in relation to depositional environments and sequence stratigraphy (systems tracts and key sequence stratigraphic surfaces) of four selected paralic and shallow marine siliciclastic successions. Typical eogenetic alterations encountered include the dissolution and kaolinitization of framework silicates, which are closely associated to shoreface facies of forced regressive systems tract (FRWST), lowstand systems tract (LST), upper part of the highstand systems tract (HST), and below the sequence boundary (SB).

5. 3. Diagenesis and Reservoir-Quality Evolution of Deep-Water Turbidites: Links to Basin Setting, Depositional Facies, and Sequence Stratigraphy

   Author : Howri Mansurbeg; Sadoon Morad; Ihsan Al-Aasm; Uppsala universitet; []
   Keywords : Bedrock geology; Diagenesis; reservoir quality; active margin; passive margin; depositional facies; sequence stratigraphy; Berggrundsgeologi;

   Abstract : A study of the distribution of diagenetic alterations and their impact on reservoir-quality evolution in four deep-water turbidite successions (Cretaceous to Eocene) from basins in active (foreland) and passive margins revealed the impact of tectonic setting, depositional facies, and changes in the relative sea level. Diagenetic modifications encountered in the turbiditic sandstones from the passive margin basins include dissolution and kaolinitization (kaolin has δ18OV-SMOW = +13. READ MORE

6. 4. Urinary diversion by the Kock ileal reservoir. Studies on clinical outcome, quality of life, bile acid and vitamin B12 metabolism

   Author : Gunnar Olofsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kock reservoir; urinary diversion; quality of life; bile acids; vitamin B12;

   Abstract : Introduction: Urinary diversion with the Kock ileal reservoir has been performed at Sahlgrenska University Hospital since 1975. One key question is the long-term consequences regarding glomerular filtration rate (GFR) and quality of life of this kind of surgery. Other important topics are the consequences due to loss of ileum. READ MORE

7. 5. Effects of Watershed Dynamics on Water Reservoir Operation Planning : Considering the Dynamic Effects of Streamflow in Hydropower Operation

   Author : Nicholas Zmijewski; Anders Wörman; Andrea Bottacin-Busolin; Francesca Pianosi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reservoir operation; dispersion processes; wave diffusion; multi-objective operation; water resource management; discharge variability; power spectrum analysis; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Water reservoirs are used to regulate river discharge for a variety of reasons, such as flood mitigation, water availability for irrigation, municipal consumption and power production purposes. Recent efforts to increase the amount of renewable power production have seen an increase in intermittent climate-variable power production due to wind and solar power production. READ MORE
