Analysis of Factors Contributing to Long Term Shallow Gas Migration to Seabed in Surface Casing Annulus
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-07)A common observation is a low rate gas bubbling from the outside of the 20” surface casing on wells located in the Haltenbanken area on Norwegian Continental Shore. This phenomenon is known as long term shallow gas migration ... -
Automated MPD level in the oil and gas industry and development possibility
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)Automation is introduced to the industrial field long time ago, but still in its first steps in the oil and gas industry. There are many reasons led to this slow of automation in this industry. These reasons related to the ... -
Automatic adjustment of drilling fluid properties
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013)The primer objective of this thesis was to implement and test, in the automated drilling hydraulics laboratory at the University of Stavanger, a system for automatic adjustment of viscosity of a fluid. The fluid used to ... -
Automatic Management of Rate of Penetration in Heterogeneous Formation Rocks
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Rate of penetration (ROP) is dependent on several factors and it is essential to properly manage and control this in order to save cost of drilling operations. Drillbotics test skid is an automated machine that is expected ... -
Automatic MPD & downhole temperature estimation and temperature effect on density
(Master thesis, 2015-06-15)Hydraulic model is the ‘brain’ of an automated managed pressure drilling (MPD) control system. It requires knowledgeable people to set up and tune before operation starts. Glenn-Ole Kaasa’s simplified dynamic wellbore model ... -
Cementing Geothermal Steam Wells
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Cementing wells with severe temperatures and/or pressures has become a common matter over the years. Running casing and designing the cement job is very difficult with temperatures above 150°C (300°F) which is a common ... -
Challenges related to magnetics and navigation within directional drilling
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Magnetic distortion of magnetometer readings affects the accuracy and efficiency of the wellbore positioning operations, which in turn degrades the industrial viability of the magnetic measurements while drilling survey ... -
