Decision Framework for Well Delivery Processes - Application of Analytical Methods to Decision Making
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:30, Doctoral thesis, 2007)A major portion of unproduced oil and gas resources are located in deep-water areas, often at sea level depths between 1500 and 3000 metres. Development of these fields with conventional technology necessitates increasing ... -
Predicted versus actual rock mass conditions: a review of four tunnel projects in Nepal Himalaya
(Journal article; Peer reviewed, 2007)The Himalayan region possesses enormous potential for hydropower development. However, there exists great challenge for the successful underground excavation due to complex geological set up of the region. It is generally ... -
An Analytical Mathematical Theoretical Study of Single-Well Push-Pull ”Echo” Tests
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:122, Doctoral thesis, 2007)Analysis of stream-line-based formulations is exercised to develop a stream-line based semi-analytical model for the single-well push-pull test, taking into account natural ground-water drift. The model is employed to ... -
Time-lapse interferometric imaging using an active source
(Master thesis, 2007)The purpose of time-lapse seismic processing is to relate changes in seismic signals to changes in reservoir parameters. A synthetic time-lapse experiment has been conducted in order to provide a controlled test environment ... -
Leakage behind casing
(Master thesis, 2007)Achieving zonal isolation by cementing annulus space between casing and well bore is an important job in many oil wells. Gas leakage in the annulus has been recognised as a major completion problem in the oil well. A ... -
Magnetization of exsolution intergrowths of hematite and ilmenite: Mineral chemistry, phase relations, and magnetic properties of hemo-ilmenite ores with micron- to nanometer-scale lamellae from Allard Lake, Quebec
(Journal article; Peer reviewed, 2007)[1] Hemo‐ilmenite ores from Allard Lake, Quebec, were first studied over 50 years ago. Interest was renewed in these coarsely exsolved oxides, based on the theory of lamellar magnetism as an explanation for the high and ... -
Uncertainty analysis of tunnel squeezing for two tunnel cases from Nepal Himalaya
(Journal article; Peer reviewed, 2007)Weak rocks such as shale, slate, phyllite and schist, and the rock mass of weakness/fault zones are incapable of sustaining high tangential stress. Severe tunnel squeezing is therefore common in the tectonically active ... -
Production of mechanically activated rock flour fertilizer by high intensive ultrafine grinding

Physical Effects Controlling Mass Transfer in Matrix Fracture System during CO2 Injection Into Chalk Fractured Reservoirs
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:72, Doctoral thesis, 2007)Tertiary recovery or Improved Oil Recovery (IOR) methods are key processes to replace or upgrade reserves, which can be economically recovered, beyond conventional methods. Therefore, the application of IOR methods offers ... -
Magnetic phases in hemo-ilmenite: Insight from low-velocity and high-field Mössbauer spectroscopy
(Journal article; Peer reviewed, 2007)[1] We have studied natural samples of hemo‐ilmenite (ilmenite with hematite exsolution lamellae) by use of Mössbauer spectroscopy. The samples are from the Allard Lake intrusion in Quebec. The stoichiometric compositions ... -
Behaviour of polymer muds under high pressure – high temperature conditions
(Master thesis, 2007)A well is classified as a HPHT (High Pressure High Temperature) well if the static bottomhole temperatures are greater than 350 °C and when the formation pressures exceed 1800 kg/m3 ECD. Mud weights as high as 2400 kg/m3 ... -
Magnetic properties and potential field modeling of the Peculiar Knob metamorphosed iron formation, South Australia: An analog for the source of the intense Martian magnetic anomalies?
(Journal article; Peer reviewed, 2007)[1] Magnetic property measurements show that the strongly metamorphosed Peculiar Knob iron formation (IF), South Australia, is coarse‐grained, high‐grade hematite with variable amounts of magnetite and maghemite. This body ... -
Reservoir modeling of water production in two unconventional resources - North American Tight Gas and South American Heavy Oil
(Doctoral theses at NTNU;2017:141, Doctoral thesis, 2007)This dissertation investigates methodologies for reservoir simulation and model tuning of wells producing water with hydrocarbon in two particular and extreme reservoir environments: cases of extremely small and very large ... -
Monitoring Overburden and Reservoir Changes from Prestack Time-Lapse Seismic Data: Applications to Chalk Fields
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:37, Doctoral thesis, 2007)Reservoir compaction due to hydrocarbon production has been observed in several North Sea reservoirs, especially the chalk reservoirs in the southern part. This compaction leads to changes in porosity and permeabilities ... -
Static and dynamic stability analyses of the 800m high Åknes rock slope, western Norway
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:128, Doctoral thesis, 2008) -
Magnetic petrology of the Devonian Achala Batholith, Argentina: titanohaematite as an indicator of highly oxidized magma during crystallization and cooling
(Journal article; Peer reviewed, 2008)Devonian magmatism in the Eastern Sierras Pampeanas (Córdoba, Argentina) is represented by elliptical, porphyritic, batholithic, late- to post-orogenic monzogranites emplaced in a metamorphic—plutonic basement. Two groups ... -
Magnetic properties of anorthosites: A forgotten source for planetary magnetic anomalies?
(Journal article; Peer reviewed, 2008)[1] Anorthosites, igneous rocks very rich in plagioclase, rarely considered to be strongly magnetic, are common on Earth, and the Moon, and inferred to be on other planets. Magnetic properties of anorthosites could be ... -
Pavement wear and airborne dust pollution in Norway
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:133, Doctoral thesis, 2008)In several large cities in Norway the traffic volume is high. The use of studded tires and other friction enhancing measures during winter leads to significant pavement wear, which in turn leads to an increase in the amount ... -
