Cost and duration estimation for deep enhanced geothermal system well
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013)Geothermal energy is today recognized as a weather independent and stable energy source with significant potential. The high cost of drilling long-reach wells is a key bottleneck and a show stopper for the realization of ... -
Coupling of trishear fault-propagation folding and ground process modelling.
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)This thesis couples two processes, tectonics and sedimentation, by simulating the kinematics of fault-propagation folding with sedimentary processes in the form of erosion, transport, and deposition, in a 3D numerical ... -
Creep behavior and loading rate dependency of chalks
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)‘‘Mechanically high porosity chalks behave as frictional materials, but with an end-cap reflecting pore collapse failure, and the mechanical properties of chalk are strongly dependent on the type of fluid in the pores’’ ... -
Cretaceous-Cenozoic tectonostratigraphic evolution of the Loppa High

Cutting transport models and parametric studies in vertical and deviated wells
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2014-01-09)Field experience shows that the accumulation of cutting in a wellbore causes several drilling problems. These include an increase in torque and drag, which may limit drilling from reaching to a desired target formation. ... -
Cuttings transport in inclined and horizontal wellbore
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Efficient cuttings transport and hole cleaning is very important for obtaining an effective drilling operation. In inclined and horizontal drilling, hole cleaning issues is a common and complex problem. This thesis explores ... -
Data Accuracy from Well Test Operations
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-12-18)This master thesis presents a study on data accuracy from well test operations. All data measuring methods, except bottomhole and surface PVT sampling, is investigated for the accuracy related to procedure and equipment ... -
Deep water well intervention and fluid selection
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Worldwide, the number of subsea wells showed a substantial increase over the last decade. This trend is particularly relevant for deep- and ultra deep-water field developments, indicating that the offshore oil and gas ... -
Deepwater Challenges & Well Control
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017)Deepwater challenges and well control problems are important drilling issues, as operators move into deeper waters and more challenging environments. The deepwater technology and the complexity of deepwater operations have ... -
Deepwater drilling problems
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)Several problems encountered in the deepwater makes it very difficult in terms of accessibility for drilling. In this work, the major problems in the deepwater are identified, and discussed from different perspectives. ... -
Deepwater operations - running and cementing casing with small clearances
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The petroleum demand is increasing and the line between success and failure is marginal. Thus, the drilling industry moves further into deeper waters, stretching the limits of engineering, economics and new technology to ... -
Depleted reservoir drilling : a study of the Ula field in the North Sea
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Ula is an oil field operated by BP in the southern part of the Norwegian North Sea. As the field matures depleted intervals are drilled to access remaining reserves. Drilling in highly mature fields is challenging, both ... -
Depleted reservoir drilling: A North Sea HPHT case study
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06)Drilling infill wells in HPHT fields can represent a severe challenge. Narrow drilling windows are prevailing in HPHT reservoirs, and pressure depletion will decrease this window even more. It may be critical to drill ... -
Depositional setting and diagenesis as keys to reservoir quality: Lower Cretaceous in the southwestern Barents Sea
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-20)Porosity and permeability are controlled by the interaction of sediment provenance, depositional processes, and diagenesis. This study attempts to determine and predict which role the depositional environment has in enhancing ... -
Depth issues in the oil patch : a study of wellbore position uncertainty in the Ekofisk Field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The understanding of the subsurface geometrical position of the wellbore is crucial. The wellbore positioning data is relied upon by different disciplines or functional groups throughout the life of any given field. For ... -
