(Journal article; Peer reviewed, 2019)he Norwegian mining industry is currently showing increasing interest in the production of metals. Recent research has demonstrated promising results identifying the high potential of the Nussir deposit for the production ... -
Optimized production profile using a coupled reservoir‑network model
(Journal article; Peer reviewed, 2019)This paper presents an integrated approach for scheduling and forecasting oil and gas production by integrating models of the entire value chain, from the reservoirs to the sales points. The methodology ensures maximum oil ... -
A reduced random sampling strategy for fast robust well placement optimization
(Journal article; Peer reviewed, 2019)Model-based decision-making in oilfield development often involves hundreds of computationally demanding reservoir simulation runs. In particular, well placement optimization under uncertainty in the geologic representation ... -
Do Various Respirator Models Fit the Workers in the Norwegian Smelting Industry?
(Journal article; Peer reviewed, 2019)Background Respirator fit testing is a method to assess if the respirator provides an adequate face seal for the worker. Methods Workers from four Norwegian smelters were invited to participate in the study, and 701 ... -
Investigating the Effects of Carbon Dioxide Injection for Enhanced Oil Recovery - The Brent Group in the Statfjord Field
(Master thesis, 2018)According to the Norwegian Petroleum Directorate, the average oil recovery in fields on the Norwegian Continental Shelf is 47\%. Thus, more than half of the reserves are yet to be produced. CO2 injection is a method for ... -
Field development from subsurface to topside optimization - Case Study: Songo Songo Gas Field, Tanzania
(Master thesis, 2018)This thesis is focused on identifying, analyzing, and evaluating the possible development concepts for optimal development of the Songo Songo Gas field, Tanzania through reservoir and surface network integration. The field ... -
Enhanced Oil Recovery - Wisting Development
(Master thesis, 2018)The average oil recovery on the Norwegian Continental Shelf is 47% (NPD 2017b). Until today, most of the oil and gas fields at the Norwegian Continental Shelf have been produced with pressure depletion or gas/water injection. ... -
Subsea Chemical Storage and Injection Station - Single line batch re-supply of chemicals - An experimental investigation into displacement mechanisms and separation methods
(Master thesis, 2018)This thesis seeks to simplify the re-supply process of a subsea chemical storage and injection (SCS\&I) station by identifying possible alternative transport solutions. Specifically, this thesis explores the technical ... -
An Experimental Study of the Use of Silica and CNC Nanofluids for EOR by Spontaneous Imbibition
(Master thesis, 2017)Approximately half of the oil is still left in the reservoirs after primary and secondary oil recovery today. To increase the oil recovery from the reservoirs it is necessary to apply Enhanced Oil Recovery (EOR) Methods. ... -
Cold Flow Technical and Cost Efficiency Analysis
(Master thesis, 2017)Nowadays, subsea multiphase pipelines are commonly used in the deepwater oil-gas fields all over the world. However, when operating at such complex deepwater conditions, the problem of solid precipitation arises due to ... -
Failure criterion of hard rock and laboratory research of rockburt
(Master thesis, 2018)In deep excavation, typical instability subjected to the high induced stress is commonly controlled by the crack initiation, propagation, and accumulation in the rock mass. The surrounding rock mass in the region of stress ... -
Evaluation of Models to Predict Liquid Loading in Gas Wells
(Master thesis, 2018)Liquid production in the form of water or condensate is essentially the most common problem in mature gas wells. For efficient operation of the well, the produced liquid must be continuously transported to the surface. ... -
Sedimentation process and stratigraphic evolution of deep-water sediments in Sørvestsnaget Basin, Southwestern Barents Sea
(Master thesis, 2015)Deep-water clastic reservoirs are one of the most important hydrocarbon plays in the Atlantic region, especially on the Norwegian Continental Shelf. In the Sørvestsnaget Basin, the provenance and origin of Tertiary sediments ... -
CDF study of two-phase flow in helico-axial pump stage
(Master thesis, 2018)Pumping is an essential part of the process of several industries. Pumping and processing fluids with different properties have revealed to be among the major challenges in the last decades. In the oil and gas industry, ... -

Numerisk 3D-modellering av hydrogeologiske forhold på Slettemoen, Krødsherad kommune - Vurdering av beskyttelsessoner rundt produksjonsbrønner, bærekraftig grunnvannsuttak og grunnvannsnivå under grustak
(Master thesis, 2018)Bakgrunnen for oppgaven er at Krødsherad kommune ønsker økt kunnskap om akviferen på Slettemoen. Formålet med oppgaven er derfor å lage beskyttelsessoner rundt produksjonsbrønnene, anslå bærekraftig grunnvannsuttak og ... -
A sedimentological study of black shales from the Spekk Formation, Norwegian Sea
(Master thesis, 0216)Black shales from the Late Jurassic-Early Cretaceous Spekk Formation have been investigated by using a detailed sedimentological approach. Four IKU drilling cores from the Norwegian Sea have been used as study material to ... -
The Unstable Rock Slopes Træstane and Hest in Sørfjorden - Structural Mapping and Hazard assessment for Different Failure Scenarios
(Master thesis, 2018)The geological survey of Norway carries out a systematic mapping of potential unstable rock slopes in Norway. In context of this, a hazard analysis and preliminary consequence assessment has been undertaken at the two ... -
Vanninfiltrasjon i fjellbrønner i forbindelse med drivingen av Follobanetunnelen
(Master thesis, 2018)En tunnel åpner et bergrom i grunnen, som påvirker den naturlige fordelingen av vann i bergmassen. Som følge av innlekkasje til tunnelen kan poretrykket i fjellet rundt tunnelen reduseres. Dette kan drenere løsmassene over, ...
