(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-05-22)Drill cuttings recovered after drilling with OBM today are treated and deposited at onshore facilities. The TWMA Company offers a new technology, which recovers drilled subsurface materials together with oil and water ... -
Applied well integrity
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Extended reach drilling is the result of industry focus to exploit fields efficiently with a minimum financial and environmental impact. Two of the ERD pioneer fields are Wytch Farm in UK and Statfjord on the Norwegian ... -
Assessment of expandable liner for the Skarv field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)BP’s Skarv field is a stacked three layer reservoir structure. The field development plan involves drilling deviated and horizontal wells into the uppermost reservoir layer, Garn, and the lowermost reservoir layer, Tilje. ... -
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 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 ... -
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 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 ... -
