Analysis of the applicability of LNG production as exemplified by the Shtokman gas condensate field
(Master thesis, 2021)In the modern world, liquefied natural gas plays an increasing role; its consumption grows from year to year. Liquefied natural gas is relevant since liquid form gas occupies 600 times less volume, is environmentally ... -
Analysis of the de-rated Burst and Collapse Resistance of a Locally Worn Tubing by using the Finite Element Method and API models
(Master thesis, 2017-06-15)A well integrity survey performed by the Petroleum Safety Authority showed that tubing related problems are a major issue on the Norwegian Continental Shelf. Caliper log runs carried out by ConocoPhillips revealed that the ... -
Analysis of the drilling fluids engineer position and the proposition of relocating the position to shore
(Masteroppgave/UIS-TN-IØRP/2012;, Master thesis, 2012)The petroleum industry in Norway is in a time of optimism, due to recent reservoir findings. However, a continuing problem for the industry is its high and increasing level of cost. This has been one of the reasons for the ... -
Analysis of the factors influencing the annulus pressure far away from downhole pressure measurements
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-14)In any drilling operation, it is important to maintain the annulus pressure within the geo-pressure margins (collapse and pore pressure on one side and fracturing pressure on the other side). The downhole pressure management ... -
Analysis of the factors that affect the target depth in deviated wells
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)This thesis presents the analysis of the factors that affect the target depth. Depth measurement is one the most important parameter and most difficult to identify. For the target depth meas ... -
