Simulation study of surfactant injection in a fractured core
Cheng, Xiaoqian; Kleppe, Jon; Torsæter, Ole (Journal article; Peer reviewed, 2019)Surfactant flooding could be used to improve water flooding in fractured reservoirs due to the main mechanisms of wettability alteration and interfacial tension reduction. However, the surfactant flooding in fractured ... -
A Simulation Study of the Barents Sea Alta Discovery - Investigation of Optimal Recovery Method
Sirevaag, Ida Nikoline Lie (Master thesis, 2018)A re-occurring topic in the petroleum industry is to enhance the oil and gas recovery while optimizing the return of investment. Decisions related to field development are critical because most of the investments are made ... -
Simulation Study of the Polymer Flooding Applied to the Norne Field E-Segment
Amirbayov, Teyyub (Master thesis, 2014)The enhanced oil recovery (EOR) methods such as polymer flooding to increase oil production from water flooded fields are becoming more attractive. Water flooding can increase recovery up to 20-40%. Various EOR methods can ... -
Simulering av gassproduksjon i kullreservoar i Eclipse 100 og Tempest MORE - Ei litteratur og casestudie av metanproduksjon i kullreservoar
Dahle, Jørgen Eikenes (Master thesis, 2013)Det vart gjort ei litteraturstudie på gassproduksjon i kullag. Dette kan best forstås gjennom eit "dual porosity" system, der gassen er lagra i adsorbert tilstand i matrix i kullet og produseres gjennom sprekkesystemt til ... -
Study of Closed-loop Reservoir Management and Case Development for Production Optimization using Brugge model
Maghsoudi, Behrouz (Master thesis, 2016)Improving reservoir performance is at the heart of all reservoir management process. Reservoir optimization enhances decision making which leads to decreased total costs and increased recovery. In practice, manual optimization ... -
Study of Pattern Search Optimization and Implementation of Hooke-Jeeves Direct Search for Production Optimization using Perforations
Møller, Silje (Master thesis, 2016)This thesis concerns the topic of petroleum production optimization using perforations. A plug-in by PhD student Einar Baumann was extended to include a second pattern search method: Hooke-Jeeves direct search. Originally ... -
Surface-Charge Alteration at the Carbonate/Brine Interface During Single-Well Chemical-Tracer Tests: Surface-Complexation Model
Khaledialidusti, Rasoul; Kleppe, Jon (Journal article; Peer reviewed, 2018)Water chemistry has been shown to affect oil recovery by affecting surface charge and rock dissolution. The single-well chemical-tracer (SWCT) test is a field method to measure residual oil saturation (Sor), in which ... -
Surfactant Enhanced Oil Recovery in Fractured Reservoirs: Simulation study of surfactant spontaneous and dynamic imbibition
Cheng, Xiaoqian (Doctoral theses at NTNU;2019:387, Doctoral thesis, 2019)Water flooding has poor performance in fractured reservoirs with mixed- or oil-wet wettability. Surfactant could be used to improve oil recovery by changing wettability to more water-wet or reducing water/oil interfacial ... -
The Effect of Field Pressure Interference: A Simulation Study on Aquifer Modeling and the Effect on Small Oil Fields from a Common Aquifer - Applied to Trell
Lunde, Magnus (Master thesis, 2017)Petroleum reservoirs do sometimes communicate through a regional aquifer. This means that a pressure drop imposed in any of the fields is transmitted across the aquifer to the other fields, and manifested as pressure ... -
The Stratigraphic Method Applied to History Matching of the Norne Field
Stensholt, Dag Morten (Master thesis, 2014)History matching is the process of improving a reservoir simulation model by modifying its parameters until simulations reproduce the observed data. This thesis presents a history match of the North Sea oil field, Norne. ... -
Up-scaling of Polymer Flooding with regards to Geologic Heterogeneities
Hong, Aojie (Master thesis, 2014)Up-scaling of reservoir model is required to save computational time and costs in the industry. Due to numerical dispersion caused by enlarged grid size and reduced reservoir heterogeneity during up-scaling process, the ... -
Upscaling polymer flooding using MRST
Danilova, Anna (Master thesis, 2016)Reservoir simulation models are widely used as a decision making tool in oil and gas industry. Modern technologies allow creating very detailed high-resolution models to represent the properties of a reservoir system as ... -
WATER CONING IN FRACTURED RESERVOIRS: A SIMULATION STUDY
Okon, Anietie Ndarake (Master thesis, 2012)Water coning is a complex phenomenon that depends on a large number of variables which include among others: production rate, perforation interval, mobility ratio, capillary pressure, etc. Its production can greatly affect ... -
"Well Placement for maximum production in the Norwegian Sea": Case Study: Norne C-segment Oil Field
Akpan, Stella Eyo (Master thesis, 2012)In petroleum fields, the essence of well placement is to develop and maintain petroleum reservoirs in order to achieve maximum production for economic benefit. Maximum production can be achieved with more oil wells, but ...
