Tunnelling challenges in Nepal
(Chapter, 2004)Nepal is a landlocked mountainous country with a population of approximately 23 millions. Being steep in topography and having many rivers originating from the glaciers of the Himalaya, Nepal has been gifted in the field ... -
Adsorptive retention of copper from acidic mine water at the disused sulphide mine at Lokken, central Norway - initial experiments using olivine
(Peer reviewed; Journal article, 2004)This paper investigates the chemical potential of using forsterite olivine to remove copper from acidic mine water through the actions of neutralisation and adsorption. The study was initiated by The Norwegian Directorate ... -
The influence of porous plates on effective drainage and imbibition rates
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:104, Doctoral thesis, 2004)The goal in petrophyscial studies is very often to obtain representative capillary pressure curves in conjunction with Sw-RI relationships for log interpretation. The most frequently used techniques today are centrifugation, ... -
Characterization of gas-lift instabilities
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:56, Doctoral thesis, 2005)This dissertation mainly investigates the occurrence and characteristics of density-wave instability in gas-lift wells. The investigation is based on a simplified gas-lift system, in which water and air are used as producing ... -
Combined Inversion of PP and PS Seismic Data for Static and Dynamic Reservoir Characterization
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:85, Doctoral thesis, 2005)Reservoir properties are mainly determined based on well log information. However, wells in most reservoirs are sparse and widely spread compared to the size of the reservoir. Seismic data is thus one of the most important ... -
Pore pressure estimation from single and repeated seismic data sets
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:31, Doctoral thesis, 2005)Høye poretrykk utgjør en risiko for boreoperasjoner på Norsk Sokkel og internasjonalt. Denne risikoen kan reduseres dersom man har kjennskap til poretrykksforholdene før boring. Poretrykk er også en viktig parameter for ... -
CO2 Injection in an Oil Reservoir with Gas Cap (Compositional Simulation Case at Heidrun Field Norway)
(Master thesis, 2006)A potential problem with CO2 Injection in oil reservoirs with gas caps is that gas cap may be contaminated by CO2. This could be an issue on the Heidrun Field where down dip using CO2-WAG is considered. Compositional ... -
Rock physics depth trend analysis using seismic stacking velocity
(Master thesis, 2006)Quantitative seismic interpretation is becoming more and more important in exploration and characterization of petroleum reservoirs. In this technology, rock physic analysis combined with seismic attributes has become a ... -
Quantitative Measurements of Mineral Microstructures: Development, implementation and use of methods in applied mineralogy
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:194, Doctoral thesis, 2006)The project has been in applied mineralogy. Advanced characterisation techniques have been developed and used as a tool for quantitatively describing geological raw materials, middlings and end products for optimal ... -
Testprogram for overskudds- og restmasser som planlegges brukt til tildekking av forurensede sedimenter
(Bioforsk Rapport;, Research report, 2006)Det er utarbeidet et testprogram for å vurdere egnethet av overskudds- og restmasser for bruk til tildekking av forurensede sedimenter. Testprogrammet vurderer materialets egnethet på generelt grunnlag, uavhengig av en ... -
Frå Nidarosen til Nidarneset: Ein ingegrert naturvitskapleg – arkeologisk – historisk rekonstruksjon av framveksten av Trondheim
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:65, Doctoral thesis, 2006)The centre of Trondheim is located on a peninsula at the mouth of Nidelva in the county of Sør-Trøndelag, Norway. A limited part of the town is an automatically protected heritage site Mellomalderbyen Trondheim (the medieval ... -
Geochemical Processes Controlling the Generation and Environmental Impacts of Acid Mine Drainage in Semi Arid Conditions
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:231, Doctoral thesis, 2006)This study evaluates the geochemical processes that control the geochemistry of acid mine drainage in semi arid conditions. The central objective is to characterise and understand the evolution of acid mine drainage and ... -
Size Reduction and Specification of Granular Petrol Coke with Respect to Chemical and Physical Properties
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:74, Doctoral thesis, 2006)Carbon required for the reduction of alumina by electrolysis in the Hall-Héroult process is supplied by the anode. Anodes are produced from a mixture of petroleum coke with coal tar pitch as the binder. The minimum theoretical ... -
