Advanced Casing Wear Model
Teigland, Andreas (Master thesis, 2017)Casing wear prediction is an important part of a well integrity assessment. Reduction in the thickness of the casing wall as a result of various wellbore operations can cause significant reduction in burst and collapse ... -
Advanced Temperature Model for HPHT Conditions
Løbergsli, Knut Vegard (Master thesis, 2015)Temperature changes of wells are analyzed in this Thesis. Wells need to be designed for all planned operations in order to maintain well integrity for the well life. Well barriers need to be numerically assessed for ... -
Advanced Tubing Design - Temperature Modeling
Lervik, Øystein (Master thesis, 2016)In casing and tubing design, one of the most important aspects is to make the well safe for operation. This includes many complex areas that need thorough understanding, with one being temperature prediction. This is a ... -
Coiled Tubing Drilling from Riserless Light Well Intervention Vessel
Bergsli, Bendik Øverland (Master thesis, 2017)Riserless light well intervention (RLWI) vessels currently have a proven capability of drilling offshore wells with coiled tubing (CT) to approximately 1000 meter measured depth (MD). The method has been used to drill ... -
Collapse prediction of pipe subjected to combined loads
Brechan, Bjørn Astor; Teigland, Andreas; Dale, Stein Inge; Sangesland, Sigbjørn; Kornberg, Even (Peer reviewed; Journal article, 2020)Prediction of tubular performance has over the last decades improved with models that are more accurate. There is a trend in the oil and gas industry where traditional uniaxial modelling is given less importance and the ... -
Digital well planning - Well Intervention
Selmer, Håkon (Master thesis, 2021)Dagens olje og gass industrien har sett en formidabel fremgang i teknologi og utstyr som er nødvendig for å kunne gjennomføre stadig mer krevende brønnintervensjoner. Brønnplanleggingsprosessen har ikke sett den samme ... -
Digital Well Planning: Next Generation Workflow
Bareksten, Magnus; Vambheim, Lars Djuve (Master thesis, 2022)Petroleumsnæringen er inne i en periode med høyt fokus på digitalisering og automatisering. Dette fokuset er spesielt drevet av en ambisjon om å redusere kostnader, effektivisere drift og øke sikkerheten. Flere nye ... -

Evaluation and Testing of Thermoset Polymer Resin for Remedial Repair of Sustained Casing Pressure
Øyan, Even Gunnarsson (Master thesis, 2017)The number of petroleum wells exhibiting pressure build-up in the annulus as a result of lost cement integrity is evident, this is known as Sustained Casing Pressure (SCP). There are several factors contributing to lost ... -
Evaluation of Industry Practice for Buckling Analysis in Well Design
Remmen, Trine (Master thesis, 2018)The development of horizontal drilling technology have enabled the production of oil and gas from thin layers. With the development of shallow, horizontal subsea wells, new challenges arises. The occurrence of compressive ... -
Evaluation of Methods and Quality Barriers in Plug and Abandonment - Technology Advances, Physical and Governing Requirements
Aasnes, Mona Øygarden (Master thesis, 2017)Improving the present P&A operation with respect to costs and safety is of current interest to the petroleum industry. This is because this operation will frequently be performed in the future due to the large number of ... -
Improved Casing Collapse Prediction with a Case Study of Asset Life Extension
Kornberg, Even Mikael (Master thesis, 2017)The current industry accepted standards of predicting collapse strength of casings are pessimistic and inaccurate. With wells being drilled ever deeper, high strength pipes are required in order to comply with rules and ... -
Influence of Hole Trajectory and Direction on MWD Survey Errors
Hassan, Syed Muhammad Reza (Master thesis, 2018)Wellbore positioning is important to meet directional drilling objectives. Inaccurate wellbore surveys can lead to wellbore collision, failure to penetrate thin reservoir sections and drilling of relief wells etc. Such ... -
Kick Tolerance for HPHT
Pettersen, Line (Master thesis, 2014)Safety is of great importance during a drilling operation. Where the worstcase scenario is that the well will kick and it will lead to a blowout. The bestway to handle disasters is to avoid them. Kick tolerance is a planning ... -
Optimized Well Design on Brage
Jensen, Marielle (Master thesis, 2015)Slot recovery operations have the intention to increase the oil recovery and extend the lifetime of maturing fields. Keeping the well cost low is an important aspect of such operations, as the recoverable resources are ...
