(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)This thesis provide a case-study of fault-seal characteristics and consequently the retained hydrocarbon column heights in the Oseberg area. The interpretation of the Oseberg structure utilized seismic and well data to map ... -
Mitigating Stick-Slip Vibrations Using Surface Control Software - A Validation of SoftSpeed II™ Using High-Speed Along-String Dynamics Measurements in a Norwegian Offshore Field
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-05-30)Stick-slip is a well known drilling related problem that causes damage and delays, often resulting in an overall more expensive well. These problems have traditionally been remedied by reducingWOB or increasing RPM ... -
Modeling of dirty sands and clay zones with poor production characteristics
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The Statfjord field is one of the oldest and largest oil and gas producing fields on the Norwegian continental shelf. It is currently at its late life production period with pressure depletion as the main production ... -
Modeling synrift sediment infill patterns of synthetic normal faults
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2016-01)Previous studies of normal faulting and their control on sedimentation have largely focussed on geometrical infill patterns from a two dimensional perspective. In order to overcome this a series of 3D models have been ... -
Modelling of Co-Current Spontaneous Imbibition – Improved Understanding of Reservoir Flow Physics
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-16)Study of recovery mechanism in naturally fractured reservoir (NFRs), such as spontaneous imbibition has high interest in the oil industry to enhance oil production. Many studies of spontaneous imbibition such as counter-current ... -
Modelling of gas production from tight shale formations: An innovative approach
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Shale gas is one of the most rapidly growing forms of natural gas. Unconventional natural gas deposits are difficult to characterize overall, but in general are often lower in resource concentration and more dispersed over ... -
