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 detection of reservoir influx in conventional drilling, managed pressure drilling and dual gradient drilling
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Reservoir influxes, or kicks, are well control incidents with the potential of severe consequences to health, safety and the environment, as well as economics. Although the main focus will always be to prevent such incidents ... -
Automatic evaluation of drilling fluid properties
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06-12)This thesis is structured in two main parts. First part covers the fundamental role of drilling fluid in the drilling process. It provides a description of the mud circulating system for conventional drilling operations, ... -
Automatic evaluation of drilling fluid properties during conventional and MPD operations
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-07-12)The primary barrier to maintain well integrity in drilling operations is the drilling fluid. With the current routines of evaluating the fluid properties and the increasingly use of automated and advanced drilling ... -
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 ... -
Bayesian Lithology and Fluid Prediction on the Mikkel Field using a geologically constrained prior model
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)The main objective of this project was to predict lithology and fluid classes from prestack seismic data at the Mikkel field in the Norwegian Sea. Segments 5 and 7 on the flank of the main field are of special interest ... -
Borehole stability on Yme
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)The main object of this thesis it to perform an in-situ stress and borehole stability evaluation of the wells in the Yme field. The Inversion technique was used find the maximum and minimum horizontal stresses. The ... -
Calculation of forces acting on a rotary steerable liner drilling system
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)Torque and drag calculations performed on a new liner drilling design indicate that a very high grade drillpipe, up to S-135, is required in order to satisfy the requirements which both axial and torsional loading place ... -
Casing design evaluation for water injectors at Valhall
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)The Valhall field is the largest field that BP operates on the Norwegian Continental Shelf, and is one of the most well known high porosity chalk fields in the Southern part of the North Sea. During many years of oil ... -
Casing wear in multilateral wells

Cement Plugging of Highly Deviated Wells Displaced in Oil Based Mud
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)When an oil or gas well is not profitable to produce from anymore, it needs to be temporarily or permanent plugged and abandoned (P&A). These operations are required in order to leave a well secured with sufficient barriers ... -
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 ... -
Centralization of casings in wells
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-03)Centralization of casings is very important in order to ensure a high quality well. Poor centralization of casing is often the main reason for bad cement jobs, which forces the operators to perform remedial cementing. This ... -
Challenges of a floating production unit in in the arctic
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2014-01-13)The challenging conditions in the deep water Arctic (>100) demands solutions that still have to be develop in order to successfully operate. In terms of production units the FPSO seems like the most likely solution to ... -
Challenges related to drilling further north in the Norwegian Arctic
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)The world’s energy demands are increasing rapidly and the oil & gas industry is forced to search for new acreages for exploration and production. The Arctic is expected to contain a vast amount of the remaining undiscovered ... -
Challenges related to magnetics and navigation within directional drilling
